# Installing a Bee Colony: Package Bees, Nucleus Colonies, and Swarms


## Key Takeaways

- Package bees require careful queen introduction and continuous 1:1 sugar syrup feeding until comb is drawn and natural nectar flow is established, as they arrive without stored food and may lack sufficient adult bees for early-season thermoregulation.
- Nucleus colonies (nucs) offer a faster start due to existing drawn comb, brood, and a laying queen, but require monitoring for pathogens like *Nosema ceranae* or deformed wing virus if the donor apiary lacks surveillance.
- Swarms present a lower-cost option but carry unpredictable genetics and potential disease exposure; they often have higher *Varroa destructor* loads, necessitating immediate integrated pest management and syrup feeding to prevent absconding.
- Biosecurity is paramount, involving adherence to WOAH Terrestrial Animal Health Code standards for transboundary movement, inspection for notifiable diseases like American foulbrood, and isolation of newly acquired colonies.
- Early monitoring for queen acceptance (presence of eggs and larvae within 5-7 days) and pest infestation (e.g., *Varroa destructor* via alcohol wash or sugar shake) is critical for colony establishment and preventing cascading failures.

---

Installing a bee colony entails selecting the appropriate source,package bees, a nucleus colony (nuc), or a captured swarm,and executing a sequence of management actions that support queen acceptance, population establishment, and disease prevention. Each source type presents distinct advantages and risks regarding timing, cost, biosecurity, and early colony vigor. The decision must integrate local flowering phenology, available equipment, and the beekeeper’s capacity for early-season inspections and supplementary feeding.

## At a Glance

| Feature | Package Bees | Nucleus Colony | Swarm |
|---------|--------------|----------------|-------|
| **Typical timing** | Early spring, after last frost, depends on supplier availability | Late spring to early summer, when donor colonies are strong | Late spring through summer, unpredictable |
| **Acceptance checks** | Verify queen release from cage after 3,5 days, monitor for balling or rejection | Evaluate brood pattern and queen presence within 7 days, observe for laying worker signs | Confirm queen presence within 5,7 days, check for egg-laying progress |
| **Feed support** | Continuous 1:1 sugar syrup until comb drawn and nectar flow begins | Moderate syrup feeding if dearth occurs, no requirement if natural forage abundant | Syrup feeding recommended until comb construction and foraging resume |

## System Context and Planning Decisions

Colony source choice must account for local disease regulations and movement restrictions. [WOAH Terrestrial Animal Health Code](https://www.woah.org/en/what-we-do/standards/codes-and-manuals/terrestrial-code-online-access/) outlines certification requirements for transboundary bee movement, including Varroa destructor and American foulbrood inspection. [USDA APHIS Livestock and Poultry Disease](https://www.aphis.usda.gov/livestock-poultry-disease) provides disease reporting protocols that apply when imported bees show signs of notifiable pathogens. Package bees, often imported from distant breeders, carry elevated risk of introducing novel mite strains or antibiotic-resistant pathogens. [Merck Veterinary Manual](https://www.merckvetmanual.com/) notes that package bees may arrive with insufficient adult bees to maintain brood temperature during early spring cold spells, necessitating advanced preparation of insulated hive bodies.

Nucleus colonies purchased from a local, certified apiary typically exhibit better establishment rates because the colony already possesses drawn comb, stored pollen, and a laying queen. However, [USDA APHIS Livestock and Poultry Disease](https://www.aphis.usda.gov/livestock-poultry-disease) advises that nucs can transmit Nosema ceranae or deformed wing virus if the donor apiary lacks surveillance. Swarms represent a lower-cost alternative but carry unpredictable genetics and potential disease exposure from unknown origins. [PubMed record 38791663](https://pubmed.ncbi.nlm.nih.gov/38791663/) emphasizes that swarms often have higher Varroa mite loads than managed colonies, requiring immediate integrated pest management upon installation.

Feasibility of early-season feeding governs timing decisions. Late winter to early spring installation of package bees demands continuous provision of 1:1 sucrose syrup until natural forage becomes reliable. [FAO Animal Production and Health](https://www.fao.org/animal-production/en/) guidance recommends that beekeepers in temperate zones delay package installation until daytime temperatures consistently exceed 15°C (59°F) and that supplementary pollen substitute be offered when natural pollen is scarce. Nucleus colonies usually require less feeding because they already contain substantial stores, but prolonged inclement weather can still force starvation.

## Core Management Framework

## Pre-Installation Preparation

Before the colony arrives, the beekeeper must assemble hive equipment, select an apiary location with proper windbreaks and morning sun exposure, and verify that local pesticide applications are not imminent. The [USDA National Animal Health Monitoring System](https://www.aphis.usda.gov/livestock-poultry-disease/nahms) data indicate that poor site drainage and insufficient forage diversity correlate with reduced colony survival during the first winter. A new hive should contain frames of foundation or drawn comb in the brood chamber, a bottom board, inner cover, and telescoping outer cover. Entrance reducers must be fitted to protect against robbing and reduce heat loss during the establishment period.

### Installation Day Procedures

The two validated methods for package bee installation,the traditional shake-out technique and the Hansen method,differ in handling of the queen cage and initial placement of bees. [A new procedure to install packages of bees](https://api.elsevier.com/content/abstract/scopus_id/84864875003) reports that shaking bees directly into the hive while suspending the queen cage between frames reduces queen loss compared to tipping the entire package. [The Hansen method: An easy and efficient way to install a bee package into a hive](https://api.elsevier.com/content/abstract/scopus_id/84958154362) involves pinching the queen cage into a frame of drawn comb, then quickly transferring the package bees onto the cage. Both procedures require careful removal of the queen cage’s candy plug or cork at the correct orientation so that attendants can feed the queen immediately.

Nucleus colony transfer involves moving the nuc’s frames into a standard hive body, maintaining the original frame order if possible to avoid disrupting brood nest temperature. The WOAH code emphasizes that any nuc frames with visible symptoms of American foulbrood must be destroyed immediately and the entire colony isolated for veterinary examination. Swarm installation begins by placing the swarm’s cluster into an empty hive body with foundation, if the swarm is clinging to a branch, the beekeeper can gently shake or brush the bees into a cardboard box before transferring them. Swarms are often hungry, so a feeder of 1:1 syrup should be offered within 30 minutes of installation to reduce absconding risk.

### Post-Installation Monitoring

First inspection timing follows source-specific intervals. [PubMed record 37161307](https://pubmed.ncbi.nlm.nih.gov/37161307/) demonstrates that queen acceptance rates for package bees can be assessed 72 hours post-installation by confirming that the queen has been released and is moving freely among workers. If the queen remains caged beyond 5 days, or if workers are balling her, the beekeeper must intervene by gently uncaging her or replacing her with a new mated queen. Nucleus colonies rarely require queen introduction intervention because the queen is already accepted, but a rapid inspection on day 5 to confirm eggs and larvae is critical to detect laying worker syndrome. For swarms, the first inspection at day 7 should verify that the queen has begun laying and that drawn comb is not excessively drone-cell oriented.

Feed support must be quantified in records. [PubMed record 30753530](https://pubmed.ncbi.nlm.nih.gov/30753530/) notes that overfeeding can lead to fermentation in the hive, particularly if syrup is provided in open feeders that invite robbing. The recommended feeding method is an internal top feeder or division board feeder that minimizes exposure of syrup to nontarget bees. Recordkeeping entries should include daily high and low temperatures, date of first egg sighting, food store estimated mass, and any mite control measure application. Early detection of mite or disease overload, as described in [PubMed record 19449626](https://pubmed.ncbi.nlm.nih.gov/19449626/) regarding Nosema, allows the beekeeper to adjust feeding and consider veterinary consultation.

Facilities and environment for colony installation should be assessed prior to receiving bees. Hive placement in an apiary requires full sun exposure in cooler climates or partial shade in hot regions to reduce thermal stress, as noted by [FAO beekeeping guidance](https://www.fao.org/animal-production/en/). Windbreaks and a nearby water source improve colony stability during the establishment period. The [hive stand](/knowledge/animal-farming/apiculture/hive-stands-elevation-benefits-construction-options) should elevate the brood chamber 15 to 20 cm above ground to deter moisture and predators. Inclement weather, especially prolonged rain or temperatures below 10°C, delays installation because bees cannot fly to forage and cluster tightly, increasing the risk of starvation. Installation should be postponed if forecast conditions are unfavorable, unless the package or nucleus is already in transit.

Nutrition and water management are critical during the first days after installation. Package bees arrive without stored honey or pollen, they rely entirely on the beekeeper for immediate feed. A 1:1 sugar syrup (by weight) is commonly provided using a feeder placed inside the hive or at the entrance. The [Merck Veterinary Manual](https://www.merckvetmanual.com/) emphasizes that syrup should be offered continuously until natural forage becomes available or until the colony draws out new comb and the queen begins laying. Pollen substitute patties may be supplied if natural pollen is scarce, but their use requires monitoring for spoilage and mold. A clean water source within 100 m of the apiary is essential, sugar syrup does not replace water for brood rearing and thermoregulation. Beekeepers should refill feeders regularly and clean them to prevent fermentation or disease transmission.

Production-stage decisions include selecting the colony source and the installation method. Package bees are an artificial unit of 0.9 to 1.4 kg of worker bees with a mated queen in a screened cage. Nucleus colonies (nucs) consist of several frames with drawn comb, brood, stored food, and a laying queen, providing a faster start to the production season. Swarms, whether natural or captured, contain a queen and worker bees of unknown health status and should be quarantined and inspected before introduction to established apiaries. The choice depends on timing, local disease risk, and the beekeeper’s experience. The [USDA APHIS Livestock and Poultry Disease](https://www.aphis.gov/livestock-poultry-disease) database indicates that colonies from unknown sources have higher prevalence of American foulbrood and varroosis. For package bees, the Hansen method describes shaking workers onto a ramp or directly into the hive body while allowing the queen to be released from her cage after a delay of 24 to 48 hours, as reported in [The Hansen method: An easy and efficient way to install a bee package into a hive](https://api.elsevier.com/content/abstract/scopus_id/84958154362). An alternative procedure involves spraying the package with sugar syrup and then pouring the bees into the hive, then placing the queen cage between frames, this technique is discussed in [A new procedure to install packages of bees](https://api.elsevier.com/content/abstract/scopus_id/84864875003). Both methods aim to reduce queen rejection and minimize the number of bees that fly away before orienting to the new hive. Nucleus colonies are installed simply by transferring the frames into a full-sized brood box, taking care not to injure the queen. Swarms can be hived by shaking or brushing them into a box fitted with frames and foundation.

Recordkeeping is a cornerstone of apiary management and should begin on installation day. Essential records include the date of installation, source of bees, breed or stock, queen mark color, and any treatments applied. The [USDA National Animal Health Monitoring System](https://www.aphis.usda.gov/livestock-poultry-disease/nahms) recommends documenting baseline observations such as colony strength in frames of bees, brood pattern quality, and presence of disease or pests. Written or digital records enable the beekeeper to track colony development, detect disease emergence early, and make informed decisions about requeening or combining colonies. Records also support compliance with regional apiary registration where required.

Welfare considerations during installation center on minimizing stress to the bees and queen. Package bees have been shaken from their source colony and confined for one to three days. They arrive dehydrated, hungry, and often disoriented. The [WOAH Terrestrial Animal Health Code](https://www.woah.org/en/what-we-do/standards/codes-and-manuals/terrestrial-code-online-access/) includes general principles for the welfare of production animals, which extend to bees through the need to avoid unnecessary suffering. Practical steps include spraying the package with lukewarm sugar syrup before opening, installing the queen cage safely between frames to protect her from aggression, and providing shade if the installation occurs in direct sunlight. Aggressive behavior from the colony during installation often signals stress or queenlessness. Killing the queen accidentally or crushing workers should be avoided by handling frames gently. The queen herself should never be gripped with forceps, instead, the cage should be opened only after confirming that the bees have accepted her. Acceptance checks at 48 hours involve observing the queen moving freely on comb, the presence of fresh eggs, and the absence of balling behavior. If the queen is missing or dead, the beekeeper must either introduce a new queen or combine the colony with a healthy one.

Worker safety during installation involves personal protective equipment (PPE) including a veil, light-colored coveralls, and gloves. Stings can cause anaphylactic reactions in sensitized individuals, beekeepers with known allergies should carry epinephrine auto-injectors. Heavy lifting of hives and supers must be performed with proper technique to avoid back injury, and apiaries should be located away from frequent human or livestock traffic. Smoke use is standard to reduce defensive behavior, but smoke should be cool and applied sparingly to the entrance and under the cover.

[Food safety](/knowledge/bacteria/livestock-bacteria/cooking-chicken-bacteria-prevention) considerations apply when honey is harvested later, but installation practices influence the risk of contaminating future honey. The [FAO Animal Production and Health](https://www.fao.org/animal-production/en/) guidelines emphasize that any extraneous substances such as antibiotics, miticides, or feed additives must be used strictly according to label directions to avoid residues. Sugar syrup fed to new packages may be consumed immediately and is not stored as honey, but after the colony is established, feeding should cease before a nectar flow to prevent syrup from entering the honey crop. Pollen substitutes should be removed before they can be incorporated into brood food that could later contaminate harvested honey.

Failure patterns after installation include queen rejection, drifting of workers, starvation, and absconding. Queen rejection is the most common cause of package failure and may be due to the queen being unfamiliar, injured, or of poor quality. A [PubMed review of honey bee health](https://pubmed.ncbi.nlm.nih.gov/38791663/) notes that queen acceptance rates are influenced by the age and pheromone profile of the queen, as well as the age composition of the worker package. Starvation occurs when syrup feeders empty and nectar is unavailable, particularly during cold spells that keep bees confined. Drifting of workers to adjacent hives is more likely when hives are placed in straight rows with identical entrances, painting entrances different colors or placing landmarks reduces this. Absconding, where the entire colony leaves the hive, is more common in swarms and packages that fail to accept the queen or find the location unsuitable. Monitoring for these failures requires an inspection at day 3 to day 5 after installation, checking for the queen, eggs, and stored syrup. A second inspection at day 10 assesses comb building and brood expansion.

Practical monitoring for disease and pests begins within the first two weeks. Varroa mite detection through alcohol wash or powdered sugar shake should be performed once the colony has sealed brood, typically after two to three weeks. The [PubMed record on honey bee colony loss](https://pubmed.ncbi.nlm.nih.gov/37161307/) highlights that early mite monitoring is critical to prevent viral disease outbreaks that destabilize a new colony. Clinical signs of American foulbrood (discolored, sunken, or perforated brood cappings with ropy remains) must be reported to veterinary authorities in many jurisdictions. The [WOAH Terrestrial Animal Health Code](https://www.woah.org/en/what-we-do/standards/codes-and-manuals/terrestrial-code-online-access/) lists American foulbrood as a notifiable disease. Beekeepers should maintain a low threshold for seeking diagnostic assistance through regional apiculture extension services or veterinarians experienced in honey bee medicine. The [PubMed study on tracheal mite and Nosema](https://pubmed.ncbi.nlm.nih.gov/19449626/) indicates that early season stress exacerbates these infections, reinforcing the need for preventive management and feed support.

In summary, successful colony installation depends on matching the source of bees to environmental conditions, providing immediate nutrition and water, careful handling to promote queen acceptance, and diligent recordkeeping and monitoring. Each of these elements interacts to reduce failure rates and promote a healthy, productive colony for the ensuing season. Professional beekeepers and veterinary advisors should weigh the advantages of package bees, nucs, and swarms against local disease pressures and the beekeeper’s ability to respond to early setbacks. Uncertainty remains about the optimal timing of queen release from cages and the best sugar concentration for syrup, these decisions are best informed by observing colony response instead of rigid schedules. When losses exceed expected levels, a systematic review of installation protocols, feed quality, and disease monitoring should be conducted with reference to the most current [USDA APHIS Livestock and Poultry Disease](https://www.aphis.usda.gov/livestock-poultry-disease) and [PubMed honey bee health reviews](https://pubmed.ncbi.nlm.nih.gov/30753530/).

### Health Observation and Monitoring

After colony installation, daily observation without disturbance is recommended for the first week. The entrance should be watched for active foraging, pollen collection, and defensive behavior. A complete internal inspection is appropriate after 5 to 7 days, assuming ambient temperature exceeds 15°C and wind is light. During this first inspection, record the presence and pattern of the queen (sight of her or of eggs and young larvae), the number of frames with capped brood, the distribution of stored nectar and pollen, and any signs of dysentery or unusual odor. The [Merck Veterinary Manual](https://www.merckvetmanual.com/) emphasizes that worker behavior at the entrance is often the earliest indicator of colony stress. Bees fanning vigorously with exposed Nasonov glands may indicate queen loss or poor ventilation. Absence of pollen inbound on a warm, dewy morning suggests brood rearing has stopped or the queen is failing.

Systematic records should include date of installation, source type (package, nucleus, or swarm), queen origin and marked color, frame count, and any supplemental feed provided. The [USDA National Animal Health Monitoring System](https://www.aphis.usda.gov/livestock-poultry-disease/nahms) conducts periodic surveys of honey bee health and recommends standardized record formats to identify early trends in mortality or disease.

### Biosecurity Measures

Biosecurity begins before installation. Used equipment from an unknown source should be considered contaminated until properly sanitized. Hives should be placed on stands at least 30 cm above ground and spaced a minimum of 1 meter apart to reduce drift and disease transmission. The [WOAH Terrestrial Animal Health Code](https://www.woah.org/en/what-we-do/standards/codes-and-manuals/terrestrial-code-online-access/) provides detailed recommendations for apiary sanitation, including disinfection of hive tools and gloves between colonies and the establishment of a quarantine apiary for newly acquired colonies or sick colonies. All imported bees, especially packages from distant suppliers, should be held in an isolated apiary for at least 4 weeks. During this period, observe for American foulbrood (AFB) symptoms , sunken, greasy cappings and a foul odor , as well as European foulbrood, chalkbrood, and parasitic mite syndrome.

The [FAO Animal Production and Health](https://www.fao.org/animal-production/en/) guidance stresses that Varroa destructor is the most serious global threat to colony establishment. Package bees often arrive with some mite load, and a single untreated infestation can collapse a small colony within months. Testing for Varroa using an alcohol wash or powdered sugar shake should be performed on the first inspection and at monthly intervals thereafter. Do not treat unless a veterinarian or experienced apiculturist has established a threshold specific to your region, season, and colony strength.

### Diagnostic and Veterinary Escalation

Colony-level disease signs that warrant immediate veterinary consultation include: spotty brood pattern without a visible queen, perforated cappings, ropiness of larval remains (AFB), mite-infested brood with deformed wings, and any neurological signs such as trembling or spinning behavior. The [PubMed record 38791663](https://pubmed.ncbi.nlm.nih.gov/38791663/) reviews the overlap between viral and pesticide toxicosis, and many clinical signs are non-specific. A definitive diagnosis often requires laboratory analysis. Submit samples of 20,30 adult bees and a 10×10 cm section of brood comb to a diagnostic laboratory accredited by the USDA Animal and Plant Health Inspection Service. The [USDA APHIS Livestock and Poultry Disease](https://www.aphis.usda.gov/livestock-poultry-disease) portal lists approved laboratories for honey bee pathogens. For notifiable diseases such as AFB, Vespa mandarinia infection (in the United States), or Tropilaelaps infestation, regulatory authorities must be notified within 24 hours.

Veterinary involvement is also required when a colony fails to accept a queen after a second attempt, or when queen marking clips or cage candy is involved in injury. Prescription medications, such as oxytetracycline for AFB control, are legally restricted in many countries and must be used under a veterinarian’s supervision. The [PubMed record 37161307](https://pubmed.ncbi.nlm.nih.gov/37161307/) highlights that indiscriminate antibiotic use in [beekeeping](/knowledge/animal-farming/apiculture/beekeeping-colony-nutrition-seasonal-management-parasite-monitoring-and-honey-harvest) can disrupt gut microbiota and promote resistance, reinforcing the need for professional oversight.

### Uncertainty and Colony Acceptance

Queen acceptance remains the most uncertain factor in installing package bees and nucleus colonies. A queen released directly without a cage is attacked instantly in a package, while in a nucleus colony she is often accepted. The Hansen method, described in [The Hansen method: An easy and efficient way to install a bee package into a hive](https://api.elsevier.com/content/abstract/scopus_id/84958154362) (2015), uses a slow-release cage placed between frames to reduce acceptance failure. Swarm installation typically yields the highest acceptance because worker bees already recognize a queen. However, if the swarm has been queenless for more than 24 hours, they may attempt to raise emergency queen cells even after a new queen is introduced.

Mortality rates during the first week are variable and depend on weather, nutrition, and parasitic load. The [PubMed record 30753530](https://pubmed.ncbi.nlm.nih.gov/30753530/) indicates that Nosema ceranae infection can be present without clinical signs yet reduce colony growth by 30%. Without laboratory testing the beekeeper cannot distinguish between typical establishment stress and subclinical disease. Recordkeeping helps identify patterns but cannot replace diagnostic confirmation.

### Sustainability

Sustainable apiary management starts with genetic diversity. Sourcing queens from local breeders adapted to the region reduces mortality from environmental stressors and reduces the need for chemical treatments. The [PubMed record 19449626](https://pubmed.ncbi.nlm.nih.gov/19449626/) discusses how selective breeding for hygienic behavior can reduce Varroa populations naturally. Installing a nucleus colony instead of a package often improves early colony growth because the frames already contain brood, bees of all ages, and stored food, which reduces the first,season energy deficit. Package bees require heavy sugar syrup feeding (1:1 by weight) for at least two weeks to stimulate wax production and brood rearing. Nucleus colonies need less supplemental feed and may build comb faster, which reduces overall resource consumption.

Sustainability also means maintaining colonies that are capable of resisting local pests and diseases without routine chemical prophylaxis. Routine biosecurity, proper apiary placement away from pesticide-dense agricultural zones, and annual requeening from screened stock contribute to long-term viability. The [FAO Animal Production and Health](https://www.fao.org/animal-production/en/) highlights the role of pollinator health in food security and recommends integrated pest management approaches that combine monitoring, mechanical control, and biological agents.

## Frequently Asked Questions

**1. How can I tell if a newly installed package bee colony has accepted its queen?**
Within 5 days you should see eggs arranged in a regular pattern at the bottom of cells. If you see only drone-sized cells or multiple queen cups with larvae, the original queen has likely been rejected or lost.

**2. Should I feed a swarm immediately after hiving?**
Yes, even if natural forage is abundant. Swarms have depleted their honey reserves and need a 1:1 sugar syrup feed for at least one week to stimulate comb building.

**3. What is the minimum frame count for a nucleus colony to survive installation?**
At least 3 frames of bees covering brood, plus 1 frame of honey and pollen. Fewer frames increase the risk of starvation and reduced temperature regulation.

**4. How do I treat Varroa mites in a new colony without harming developing brood?**
Some organic acid treatments (oxalic acid vaporization or trickling) are effective only when brood is absent or minimal. For a colony with brood, consult a veterinarian for a formic acid product or synthetic miticide that is labeled for use during brood rearing.

**5. Is it legal to install a colony from outside my state or province?**
Many regions require a health certificate or import permit. Check with your state department of agriculture or national veterinary authority before moving bees across borders to prevent introducing exotic diseases.

**6. Can I introduce a new queen if the original queen is still present?**
Only after removing the existing queen. Two queens in one hive will eventually fight, and the stronger one (usually the younger) will survive. If you cannot find the old queen, place the new queen in a cage, the workers will decide which queen to keep.

**7. Why does my package colony abscond after three days?**
Absconding is often caused by a strong odor of pesticide, heavy mite infestation, or a queen that is not releasing enough pheromone. Inspect the hive for dead bees at the entrance and test for pesticide residues.

**8. How often should I inspect a newly installed colony in the first month?**
Once a week. More frequent inspection can damage comb and stress the bees, less frequent inspection may allow disease or queen failure to become irreversible.

### Educational Veterinary Notice

This article provides general guidance for beekeepers and animal health professionals. Colony establishment outcomes vary widely based on local climate, forage availability, pest pressure, and beekeeper skill. A veterinarian with experience in honey bee medicine should be enlisted to design a health management plan specific to your operation. Regulatory requirements for disease reporting and treatment differ among jurisdictions, the WOAH Terrestrial Code and national apiary programs are authoritative references. No single installation method guarantees colony survival, and integrated observation, recordkeeping, and professional consultation remain the foundation of successful beekeeping.


## At a Glance

The following table summarizes the three primary sources of bee colonies and their key attributes for installation.

| Source | Typical Colony Size | Establishment Time | Cost | Risk of Disease | Need for Queen Acceptance |
|--------|---------------------|-------------------|------|-----------------|--------------------------|
| Package Bees | 3 lb (approx. 10,000,12,000 workers) plus one queen | Several weeks for comb building and brood cycle | Moderate | Low (queen and workers from controlled breeder) | High, queen must be accepted by workers |
| Nucleus Colony (Nuc) | 4,5 frames with brood, stores, and a laying queen | 1,2 weeks to expand to full hive | Higher | Moderate (may carry local pathogens) | Low, queen already accepted and laying |
| Swarm | Variable (leaves parent colony, can be 5,000,30,000 workers) | Immediate comb building but no brood initially | Low (often free) | Variable (depends on origin) | Moderate, queen may be mated but acceptance usually high |

Acquiring bees from each source involves different handling protocols, timelines, and precautions. Package bees require a deliberate queen introduction method, nucleus colonies are a nearly complete mini,hive, and swarms demand rapid capture and placement to prevent secondary swarming or loss.

## Preparing for Colony Installation

### Timing and Weather

Install colonies when temperatures are consistently above 10 °C (50 °F) and when at least a week of mild weather is forecast. Swarms captured in early spring require close monitoring for nutritional support, as natural forage may be limited. Package bees and nucs are typically ordered for delivery when dandelion or maple bloom begins. Avoid installation during rain or strong winds, bees are less likely to orient to the hive when conditions are poor.

### Hive Placement

Place the hive on a level, dry area with morning sun and some afternoon shade in hot climates. Tilt the hive slightly forward to allow condensation to run out of the entrance. Ensure the entrance faces away from prevailing winds and heavy foot traffic. Remove all weeds and tall grass directly in front of the hive to facilitate orientation flights. For package bees, provide a small ramp or branch near the entrance so clustering bees can easily re,enter.

## Installing Package Bees

### Equipment Needed

A 3,lb package consists of a screened wooden box with a can of sugar syrup (or fondant) and a separate queen cage. You will need a hive body with frames (nine or ten), a feeder (entrance feeder or frame feeder), and a spray bottle with 1:1 sugar syrup by volume.

### Step,by,Step Process

Remove the syrup can and the queen cage from the package. Inspect the queen and confirm she is alive. Hang the queen cage between two center frames, ensuring the candy plug is accessible. Remove the cork from the candy end and puncture the candy with a small nail. Reassemble the hive body. Sprinkle the worker bees through the screen with sugar syrup, then remove the cover of the package cage. Shake the bees into the empty hive body in front of the queen cage. Replace the hive top and feed immediately with 1:1 syrup. After three to four days, open the hive to confirm the queen is released.

## Installing a Nucleus Colony

### Transferring Frames

Nucleus colonies come with a mated queen already laying. Prepare a full,size hive body with frames. Remove the frames from the nuc box one by one, placing them in the same order into the center of the new hive body. Fill the empty spaces with foundation frames. The nuc box often contains drawn comb and stores, so minimize disruption. Provide entrance reducer for the first week to help the small population defend the hive.

### Feeding and Monitoring

Feed a nuc with 1:1 syrup if natural nectar is not abundant. Do not feed if robbers are active. After one week, inspect for the queen and confirm that she is laying eggs in a consistent pattern. If the nuc arrived with an older queen, consider requeening after three to four weeks if brood pattern is spotty.

## Installing a Swarm

### Capture and Containment

Swarms are clusters of bees that have left the parent colony with a queen. Gently shake or brush the swarm into a cardboard box or a dedicated swarm trap. Use a smoker sparingly, too much smoke can cause the queen to take flight. Keep the box closed and cool until you transfer the bees.

### Hiving the Swarm

Place a hive body with a few frames of drawn comb (if available) or foundation near the capture site or at the apiary. Dump the bees directly in front of the entrance. The queen will typically walk in, and the workers will follow. Feed the swarm with 1:1 syrup to encourage comb building. Since swarms lack stored food, they cannot tolerate a gap in nectar. Check after one week for eggs and larvae. If no eggs are visible, the queen may be lost or not mated.

## Post,Installation Care

### Feeding Regimen

All new colonies require supplemental feeding until they have drawn out at least three frames of comb and have stored 4,6 lbs of honey. Use a contact feeder (jar or baggie) placed directly above the cluster. Increase hole size slowly to avoid drowning. Reduce feeding after six weeks if a strong nectar flow is present.

### Disease and Pest Monitoring

Inspect colonies every 7,10 days during the first month. Look for signs of chalkbrood, foulbrood, or Varroa mites. Package bees and nucs from certified breeders carry less disease, but swarms can introduce uncontrolled pests. Perform a sugar roll or alcohol wash for mites only after the colony has developed a brood cycle (approximately 21 days). Do not apply synthetic treatments without a proven need.

### Queen Acceptance

For package bees, queen acceptance is confirmed when you find evidence of egg,laying within 5,7 days. For nucs, the queen is already accepted. For swarms, observe that the queen is present and not injured. If a queen is rejected, the colony may start queen cells. Remove any supersedure cells unless you intend to let the colony raise a new queen.

## Frequently Asked Questions

**1. How long can package bees remain confined before installation?**
Package bees should be installed within 24,48 hours of receipt. If immediate installation is impossible, keep them in a cool (10,15 °C or 50,59 °F), dark, well,ventilated area and spray the screen with sugar syrup twice daily.

**2. Can I combine a weak nuc with a package to boost its strength?**
Combining two weak colonies is possible but carries a high risk of disease transmission and queen conflict. Use the newspaper method only after both colonies have confirmed disease,free status. Combining is not recommended for beginners.

**3. What should I do if the queen in a package is dead on arrival?**
Contact the supplier for a replacement queen. In the interim, introduce the workers to a hive with a frame of open brood from another colony to help them accept a new queen later. Never leave queenless workers alone for more than three days without brood.

**4. How do I prevent swarms from absconding after installation?**
Use a queen excluder at the entrance for the first 24 hours, or place the hive in a location where the queen cannot easily fly off. Feed heavily and provide drawn comb. Absconding is more common in captured swarms than in packages or nucs.

**5. Is it safe to install a colony during a light rain?**
No. Rain prevents orientation flights and causes bees to cluster on the outside of the hive. Wait for dry, calm weather. If a storm is imminent, delay installation until the next day.

**6. How many frames of brood should a nuc contain?**
A standard nuc has four to five frames. At least two frames should contain capped brood and larvae, and one frame should have honey and pollen. Ensure the queen is laying in a compact pattern.

**7. Can I install a package directly onto an empty hive that previously housed a diseased colony?**
No. Old comb can harbor spores of American foulbrood, chalkbrood, or viruses. Scorch the hive body with a propane torch or replace with new equipment. Never reuse comb from a disease,affected hive.

**8. Why do my package bees cluster outside the entrance instead of entering?**
The queen may not have been released from her cage, or the bees are orienting to a different location. Check the queen cage for obstruction and reduce the entrance size. If clustering persists after 24 hours, gently herd them back into the hive with a feather or soft brush.
