Beekeeping Facility Biosecurity: Design and Protocols

By Dr. Zubair Khalid, DVM, MS, PhD · 2026-08-14

Key Takeaways

• Apiary biosecurity hinges on physical facility design and strict operational protocols to mitigate disease transmission, primarily driven by beekeeper activities. Key design elements include a single entry point, dedicated equipment cleaning stations, and distinct zones for healthy and sick colonies, with new apiaries sited at least 2 miles from known diseased colonies and 100 feet from high-traffic areas.
• Pathogen and parasite transmission routes, such as Paenibacillus larvae spores for American Foulbrood (AFB) surviving for decades on equipment, or Varroa destructor mites moving via bee drift and contaminated brood frames, necessitate rigorous hygiene. Color-coding tools per apiary yard and disinfecting all equipment between yards using a 10 percent bleach solution or commercial disinfectant are critical preventative measures.
• Quarantine protocols are essential for all new colonies, splits, and queens, requiring a minimum 30-day isolation period with thorough inspections to detect subclinical infections or mite infestations before introduction to main yards. Used equipment, particularly hive bodies and frames, poses a significant risk for AFB introduction and requires gamma irradiation or burning for decontamination.
• Routine inspections every 14 days during the active season are crucial for early disease detection, including monitoring for AFB (sunken cappings, ropey larvae), European Foulbrood (twisted larvae), chalkbrood (mummified larvae), and Varroa mite infestation levels via alcohol washes or sugar rolls.
• A written biosecurity plan, reviewed annually, detailing facility layout, quarantine procedures, inspection schedules, cleaning protocols, and response plans for disease outbreaks, is fundamental. Training personnel on these protocols and seeking professional veterinary or state apiarist consultation at the first sign of serious diseases like AFB or unexplained colony death is paramount.

Keeping honey bees healthy starts long before you spot the first symptom of disease. The layout of your apiary, the way you move equipment between hives, and the habits you build around every inspection all determine whether a single sick colony becomes a yard-wide outbreak or stays contained. This guide covers the full scope of apiary biosecurity for beekeepers who are planning a new facility, expanding an existing operation, or tightening up loose practices. It is written for sideliners managing a few dozen hives as well as commercial operations running thousands. You will find practical design principles, step-by-step protocols, recordkeeping templates, and clear guidance on when to bring in professional help.

At a Glance

• Place new apiaries at least 2 miles from known diseased colonies and at least 100 feet from high-traffic areas, livestock pens, and standing water.
• Design the facility with a single entry point, a dedicated equipment cleaning station, and separate zones for healthy and sick colonies.
• Use a color-coding system for tools: one set per apiary yard, never shared between yards.
• Quarantine all new colonies, splits, and queens for at least 30 days before introducing them to your main yards.
• Inspect brood frames at least every 14 days during the active season and record what you see on a standardized form.
• Disinfect all tools, gloves, and hive bodies between yards using a 10 percent bleach solution or a commercial beekeeping disinfectant.
• Feed only from clean internal feeders, never shared community feeders placed outside the hive.
• Keep a written biosecurity plan and review it every spring before the first inspection.
• Call your state apiarist, extension apiculturist, or veterinarian at the first sign of American foulbrood, European foulbrood, or unexplained colony death.

Understanding Disease Transmission in Apiaries

Honey bees face a wide range of pathogens, parasites, and pests. The most serious threats include American foulbrood (AFB), European foulbrood (EFB), chalkbrood, sacbrood, deformed wing virus, Nosema species, and the parasitic mite Varroa destructor. Each of these moves through a colony and between colonies in different ways, but the common thread is that beekeeper activity is the single biggest vector for spreading disease across yards.

How Diseases Spread Between Colonies

AFB is caused by the bacterium Paenibacillus larvae. Its spores can survive for decades on equipment, in honey, and in wax. When you move a frame from a sick colony to a healthy one, you transfer spores directly. When you use the same hive tool without cleaning it, you transfer spores from one colony to the next. Even your gloves and veil can carry spores if you handle infected brood and then move to another hive.

EFB is caused by Melissococcus plutonius. It spreads through contaminated food, especially when you move frames of honey or pollen between colonies. Chalkbrood and sacbrood are fungal and viral diseases respectively, and both spread through contaminated equipment and stressed colonies.

Varroa mites are the most widespread threat. They reproduce inside sealed brood cells and feed on developing bees. When bees drift between colonies, mites move with them. When you move brood frames between colonies, you move mites. When you combine weak colonies or add frames of capped brood to boost a struggling hive, you are importing mites.

Why Facility Design Matters

The physical layout of your apiary can either amplify or interrupt these transmission routes. A well-designed facility separates clean and dirty zones, provides dedicated spaces for equipment cleaning and storage, and makes it easy to follow good hygiene habits. A poorly designed facility creates bottlenecks where tools pile up, where hive bodies sit stacked on the ground, and where the only water source is shared by multiple yards.

The design phase is the cheapest time to make changes. Moving a fence, adding a gate, or pouring a concrete pad after the fact costs more and disrupts your operation. If you are planning a new facility, take the time to get the layout right from the start.

Facility Design Principles for Apiary Biosecurity

Site Selection

The first decision is where to place the apiary itself. Bees forage over a radius of roughly 2 to 3 miles, so you cannot fully isolate your bees from neighboring colonies. What you can control is the immediate environment around your hives.

Choose a site that gets morning sun. This encourages early foraging and helps bees dry out dew and condensation. Avoid low-lying areas where cold air settles and where moisture collects. Wet conditions stress colonies and create favorable environments for fungal diseases.

Place hives at least 100 feet from livestock pens, poultry houses, and manure storage areas. Flies that breed in manure can carry pathogens to your hives. Place hives at least 20 feet from human foot traffic paths. Bees become defensive near high activity zones, and the more people move through the yard, the higher the chance of accidental hive disturbance.

Consider the prevailing wind direction. Orient hive entrances away from prevailing winds to reduce drafts inside the hive. In cold climates, a windbreak of trees or a fence can help colonies maintain internal temperature with less energy.

Water is essential. Bees need a reliable water source within a few hundred feet of the hive. Provide a clean shallow water source such as a birdbath with pebbles or a purpose-built bee watering station. Change the water regularly to prevent mosquito breeding and algae growth. Do not place the water source where livestock or pets can contaminate it.

Zoning the Facility

Divide your facility into clear zones based on contamination risk. The three-zone system works well for operations of any size.

The clean zone is where you store new equipment, packaged bees, queens, and feed that has not been opened. This area should be indoors or under cover, away from bee flight paths. Nothing that has touched a hive enters the clean zone without being disinfected first.

The transition zone is where you work. This includes the equipment cleaning station, the tool storage area, and the inspection staging area. The transition zone is where contamination is most likely to occur, so it needs hard surfaces that can be washed and disinfected.

The dirty zone is the apiary itself and the area around it. Once equipment enters the apiary, it is considered contaminated until it is cleaned. Hive bodies, frames, lids, and bottom boards that come out of the apiary move to the cleaning station, not back to the clean zone.

Single Entry Point

Design the facility with a single vehicle and foot entry point. This gives you a natural checkpoint where you can control what enters and leaves. A gate that you close and latch prevents unauthorized access and keeps out stray animals.

If you run multiple apiary yards, the entry point to each yard should have a boot wash station. A shallow pan with a disinfectant solution that you step through before entering the yard is simple and effective. Change the solution daily or whenever it becomes visibly dirty.

Equipment Cleaning Station

The cleaning station is the most important piece of infrastructure you will build. It should have a concrete or gravel pad that can be washed down, a water supply, and drainage away from the apiary. A pressure washer is useful for removing wax and propolis, but it is not a substitute for disinfection.

The station needs a dedicated workbench for inspecting frames and hive bodies. The bench should be non-porous, such as stainless steel or heavily sealed wood, so it can be scrubbed and disinfected. Keep a supply of clean rags, brushes, and scrapers at the station. Do not bring these items into the apiary and then return them to the station without cleaning.

Tool Storage

Store tools in a clean, dry location between uses. Hive tools, frame grips, and smokers should be cleaned and disinfected after each yard visit. A simple system is to have a bucket of disinfectant at the cleaning station. After finishing a yard, soak tools in the bucket for 10 minutes, rinse, dry, and store.

Color-coding tools by yard is a practical way to prevent cross-contamination. Paint the handles of hive tools, frame grips, and gloves with a distinct color for each yard. Red tools stay at yard A, blue tools stay at yard B, and so on. This eliminates the risk of accidentally carrying contaminated tools between yards.

Hive Yard Layout

Hive Spacing

Spacing hives too closely together increases the risk of robbing and disease spread. Robbing occurs when bees from one colony steal honey from a weaker colony. During robbing, bees from different colonies fight at the entrance, and diseases can spread through the food being stolen.

Space hives at least 6 feet apart within a row. Place rows at least 15 feet apart. This spacing reduces robbing pressure and gives you room to work around each hive without bumping into neighbors.

Entrance Orientation

Orient hive entrances in different directions within a yard. When all entrances face the same way, bees returning from foraging can drift into the wrong hive, especially on windy days. Drifting spreads mites and viruses. Alternating entrance directions reduces drift.

Windbreaks and Sun Exposure

Plant windbreaks or install fence panels on the prevailing wind side of the yard. Windbreaks reduce heat loss from hives in winter and reduce stress on bees during the active season. They also create a calmer flight path for bees entering and leaving the hive.

Ground Cover

Keep the ground directly in front of hive entrances clear of tall grass and weeds. Tall vegetation blocks bee flight and creates humid microclimates that favor fungal growth. Mow or trim regularly. Some beekeepers lay landscape fabric or gravel in front of hives to suppress weeds and create a clean work surface.

Isolation Yards

For operations with multiple yards, designate one yard as the isolation yard. This yard is positioned at least 2 miles from your other yards, preferably more. Use the isolation yard for new colonies, splits, and any colony showing signs of disease. If you have only one yard, create an isolation zone at the far end of the yard, separated by at least 50 feet from your main colonies.

Quarantine Protocols for New Bees and Equipment

Quarantining New Colonies

Every new colony that enters your operation is a potential disease risk. This includes packaged bees, nucs, swarms you collect, and colonies you purchase from other beekeepers. Even a healthy-looking colony can carry AFB spores or mites that have not yet reached detectable levels.

Quarantine all new bees in the isolation yard for at least 30 days. During this period, inspect them thoroughly at least twice. Look for signs of disease, check mite levels with an alcohol wash or sugar roll, and observe the brood pattern. Only move the colony to your main yard after it has passed all inspections and shown no signs of disease.

Quarantining Equipment

Buying used equipment is a common way for beekeepers to save money, but it is also a common way to bring AFB into a clean operation. Never buy used hive bodies, frames, or honey supers without knowing their history. If you do buy used equipment, quarantine it and disinfect it before introducing it to your apiary.

The most reliable way to disinfect wood and wax equipment is gamma irradiation, which kills AFB spores. Some areas have commercial facilities that offer this service. If irradiation is not available, scorching with a flame torch can kill spores on wood surfaces, but it does not penetrate into cracks and joints. Do not rely on scorching alone for AFB decontamination.

Queen Introduction

Queens are a disease risk because they are shipped from breeding operations that may have different disease pressures than your area. All new queens should be introduced through a cage with the attendant workers that came with her. The cage keeps the queen separated from the colony until her pheromones are accepted. During this time, monitor the colony for signs that the queen was rejected.

Feed and Supplement Safety

Feed is a common disease vector. Honey from unknown sources can contain AFB spores and should never be fed to bees. Pollen substitutes are generally safe, but pollen collected from unknown hives can carry viruses and spores. Use only commercial pollen substitutes or pollen you have collected from your own healthy colonies.

Internal feeders are safer than external community feeders. When multiple colonies share an external feeder, bees from different hives crowd together and can transmit diseases through shared food. Internal feeders, such as frame feeders or top feeders, keep each colony feeding separately.

Hygiene Protocols for Routine Inspections

Before You Start

Before opening the first hive, lay out your equipment in a clean, organized way. Have your hive tool, frame grip, smoker, and inspection record sheet ready. Have a bucket of disinfectant and clean rags at the cleaning station.

Wear gloves. Nitrile gloves are better than leather because they can be changed between yards or even between hives if you are working with a colony showing disease symptoms. If you use leather gloves, disinfect them between yards.

Inspecting the First Hive

Open the hive gently. Use your smoker sparingly. Too much smoke stresses the bees and can cause them to fill on honey, which makes the inspection harder and increases the risk of damaging brood.

Work through the frames systematically. Start at one side and move across, checking each frame for brood pattern, signs of disease, and the presence of the queen. Look for the specific signs of AFB: sunken or perforated cappings, dark greasy-looking brood cells, and ropey brown material when you probe a cell with a toothpick. EFB shows as twisted, discolored larvae that have melted into a brown mass at the bottom of the cell.

Between Hives

Between hives, scrape any wax, propolis, or debris off your hive tool onto the ground. Do not wipe it on your gloves and then continue. If you are working through a yard where you have seen any signs of disease, change gloves between hives and dip your hive tool in disinfectant.

Between Yards

When you finish a yard, clean all tools before moving to the next yard. Soak hive tools and frame grips in disinfectant for at least 10 minutes. Rinse and dry them. Change gloves. Change your boots or step through a boot wash. Wash your hands thoroughly with soap and water or use an alcohol-based hand sanitizer.

Smoker Management

The smoker is a hidden disease vector. The inside of a smoker accumulates tar and resin from burning material, and these residues can harbor spores. Empty the smoker after each use and scrape out the interior. Disinfect the interior with a bleach solution and rinse thoroughly. Do not use the same smoker between yards without cleaning it.

Step-by-Step Cleaning and Disinfection Protocols

Tools and Gloves

Mix a disinfectant solution of 1 part household bleach to 9 parts water. This 10 percent bleach solution kills most bacterial pathogens, including AFB spores, when applied for at least 10 minutes. Note that bleach is corrosive to metal, so rinse tools thoroughly after soaking and dry them completely.

For hive tools, frame grips, and queen marking cages, soak in the bleach solution for 10 to 15 minutes. Rinse with clean water and dry. For gloves, wash the exterior with soap and water, then wipe with a disinfectant wipe or dip in bleach solution. Rinse thoroughly.

Commercial beekeeping disinfectants are available and some are less corrosive than bleach. Follow the manufacturer's instructions for concentration and contact time. Whichever disinfectant you choose, it must be labeled for use against the pathogens you are targeting.

Hive Bodies and Frames

Wooden hive bodies and frames are harder to disinfect than tools because they are porous. The most effective approach is to scrape off all wax, propolis, and debris, then wash with hot soapy water, then apply disinfectant.

For routine cleaning, a pressure washer with hot water removes most debris. After washing, spray with a disinfectant solution and let it sit for the recommended contact time. Rinse thoroughly and allow to dry completely in the sun. UV light from the sun provides an additional level of disinfection.

For AFB-contaminated equipment, do not attempt to disinfect at home. Contact your state apiarist or extension agent for guidance. In most cases, the equipment should be burned or sent for gamma irradiation.

Protective Clothing

Veils, coveralls, and jackets should be washed regularly. Hot water with detergent is sufficient for most pathogens. If you have been working with a diseased colony, wash your clothing immediately after the inspection and do not wear it again until it has been washed.

Extraction Equipment

Honey extraction equipment is a major disease vector because it comes into contact with honey from many colonies. If you extract honey from a colony with AFB, the spores contaminate the extractor, uncapping tank, and any equipment that touched the honey.

After each extraction session, disassemble the extractor and wash all parts with hot soapy water. Rinse thoroughly and spray with a disinfectant solution. Rinse again and allow to dry completely. Store the extractor in a clean, dry location.

Disease Surveillance and Monitoring

Regular Inspection Schedule

During the active season, inspect each colony at least every 14 days. This interval catches most brood diseases before they spread throughout the colony. It also allows you to monitor mite levels and take action before they reach damaging thresholds.

Each inspection should include a visual check of the brood pattern, a check for disease symptoms, and a mite count. The alcohol wash method is the most accurate way to count mites. Collect about 300 bees from the brood nest into a jar, add alcohol, shake, and count the mites that fall off. A mite count above 3 mites per 100 bees in the spring or 6 mites per 100 bees in the fall indicates treatment is needed.

Recognizing Key Diseases

American foulbrood is the most serious bacterial disease of honey bees. It is caused by Paenibacillus larvae and produces spores that can survive for decades. Symptoms include sunken and perforated brood cappings, dark greasy cells, and a foul odor. When you probe a diseased larva with a toothpick, it stretches out into a ropey brown thread.

European foulbrood is caused by Melissococcus plutonius. It affects younger larvae and produces a sour smell. Diseased larvae appear twisted, discolored, and often melt into a brown mass at the bottom of the cell. EFB is less persistent than AFB, but it still requires treatment.

Chalkbrood is a fungal disease caused by Ascosphaera apis. Infected larvae become hard, white, mummified masses that resemble chalk pieces. Chalkbrood is often a stress indicator. Improving ventilation, reducing moisture, and ensuring adequate nutrition often resolves the problem.

Nosema is a microsporidian parasite that affects adult bees. It causes dysentery, reduced lifespan, and poor colony performance. Nosema spores are spread through fecal contamination inside the hive. Good hygiene and proper winter feeding reduce the risk.

Monitoring for Varroa Mites

Varroa mites are the most damaging pest of honey bees worldwide. They feed on the fat bodies of adult bees and developing brood, and they transmit viruses including deformed wing virus. A heavy mite infestation can collapse a colony within months.

Monitor mite levels at least monthly during the active season. The alcohol wash method is the standard. Use the treatment thresholds from your local extension service, as they vary by region and season.

Recordkeeping

Write down what you see at every inspection. A standardized record sheet makes it easy to spot trends and catch problems early. Your record sheet should include the date, hive identification number, queen status, brood pattern quality, signs of disease, mite count, and any treatments applied.

Keep a separate log for each apiary yard. This log should track the movement of equipment and bees into and out of the yard. If a disease outbreak occurs, the log helps you trace the source and identify which other yards may be at risk.

When to Call a Professional

Do not try to diagnose and treat AFB on your own. If you suspect AFB, contact your state apiarist or extension apiculturist immediately. They can confirm the diagnosis and guide you through the regulatory requirements. In many states, AFB is a reportable disease, and failure to report it can result in fines.

Call a veterinarian who works with bees if you see signs of disease that you cannot identify, if a colony collapses without an obvious cause, or if you need guidance on treatment options. A veterinarian can help you develop a treatment plan and can prescribe medications when needed.

Common Biosecurity Mistakes

Sharing Tools Between Yards

The most common mistake beekeepers make is using the same hive tool across multiple yards without cleaning it. A hive tool picks up wax, propolis, and potentially spores from every hive it touches. One yard with an undetected AFB infection can contaminate every tool used in that yard, and those tools then carry the spores to every other yard.

Feeding Honey from Unknown Sources

Feeding honey from grocery stores, from unknown beekeepers, or from dead colonies is a fast way to introduce AFB. Honey can contain spores that are invisible and tasteless. Only feed honey from your own healthy colonies, and even then, only if you are certain the colony showed no signs of disease.

Combining Weak Colonies Without Testing

Combining a weak colony with a strong colony is a common management practice, but it is dangerous if the weak colony has a disease. Always test the weak colony for AFB and other diseases before combining. If you see any sign of disease, do not combine. Isolate the weak colony and treat it separately.

Ignoring Mite Counts

Mite counts are the single most important monitoring tool you have. Skipping a monthly mite count because you are busy is a recipe for disaster. By the time you see visible mite damage, the colony may be beyond saving.

Using the Same Smoker Without Cleaning

The smoker is often overlooked in biosecurity planning. The interior of a smoker accumulates sticky tar that can harbor spores. Clean the smoker after each use and disinfect it regularly.

Letting Visitors Walk Through the Apiary

Visitors are a biosecurity risk because they may have visited other apiaries before coming to yours. Ask visitors to wear clean clothing and clean boots. Provide boot covers or a boot wash station. Do not let visitors handle hive equipment unless they are wearing gloves.

Decision Thresholds and Response Plans

When to Isolate a Colony

Isolate a colony at the first sign of any disease symptom. Move it to the isolation yard immediately. If you do not have an isolation yard, place it at least 50 feet away from your other colonies and mark it clearly. Do not work on the isolated colony and then return to your main yard without changing gloves and disinfecting your tools.

When to Treat

Treat for Varroa mites when your mite count exceeds the threshold for your region and season. Treat for Nosema when you see signs of dysentery and confirm the diagnosis. Treat for EFB if the infection is moderate to heavy or if the colony is weak.

Do not treat for AFB. AFB is not treatable in the field. The only options are burning the colony and equipment or submitting the equipment for gamma irradiation. Contact your state apiarist before taking action, because they will guide you through the regulatory process.

When to Destroy a Colony

Destroying a colony is a last resort, but it is sometimes the only responsible option. Colonies with confirmed AFB should be destroyed and burned. The bees should be killed humanely, the hive bodies and frames burned, and the location marked so you do not place new bees there for at least one year.

When to Call for Help

Call for help when you see any of the following: a colony that dies suddenly without an obvious cause, a brood pattern that looks abnormal but you cannot identify the cause, mite counts that remain high despite treatment, or any sign of a disease you cannot identify. Your state apiarist, extension apiculturist, or veterinarian are the right people to call.

Seasonal Biosecurity Calendar

Spring

Spring is the highest-risk season for disease because colonies are building up after winter and brood is expanding rapidly. Conduct your first full inspection as soon as temperatures allow, usually when daytime highs reach 60 degrees Fahrenheit. Check for brood diseases, mite levels, and queen status. Clean and disinfect all equipment before the season starts.

Summer

Maintain your 14-day inspection schedule through the summer. Monitor mite levels monthly. Watch for signs of robbing during nectar dearths. Keep the apiary clean and mowed. Replace any dirty or contaminated equipment promptly.

Fall

Fall is the time to prepare for winter and to reduce mite loads before the winter cluster forms. Treat for mites according to your monitoring results. Consolidate weak colonies only after testing for disease. Clean all extraction equipment and store it properly.

Winter

Winter inspections are limited, but you can still monitor colony health from the outside. Check for activity on warm days, listen for buzzing, and look for signs of dysentery on the hive front. Plan your spring biosecurity improvements during the winter months when you have time to think.

Designing a Biosecurity Plan for Your Operation

Written Plan Components

A written biosecurity plan is a requirement for commercial operations and a good practice for any beekeeper. The plan should include your facility layout, your quarantine procedures, your inspection schedule, your cleaning and disinfection protocols, and your response plan for disease outbreaks.

Write the plan so that anyone working in your apiary can follow it. Include specific instructions for each task. For example, the plan should state exactly how to clean a hive tool between yards, not just say "clean tools between yards."

Training Your Team

If you have employees or family members who help with the bees, train them in the biosecurity plan before they start working. Show them how to clean tools, how to change gloves, and how to recognize disease symptoms. Test them on the procedures and correct any mistakes before they work with the bees.

Reviewing and Updating the Plan

Review your biosecurity plan every spring before the first inspection. Update it when you add new yards, change equipment, or learn about new disease threats. A plan that sits in a drawer and is never updated is not worth the paper it is written on.

Frequently Asked Questions

How far should I keep my apiary from neighbors' hives?

The foraging range of honey bees is 2 to 3 miles, so you cannot fully isolate your bees from neighboring colonies. However, you should place your hives at least 100 feet from any known diseased colony. If you are unsure about the health of neighboring colonies, keep your hives as far apart as practical and focus on your own biosecurity practices.

Can I disinfect used hive equipment that might have American foulbrood?

Home disinfection methods do not reliably kill AFB spores. The spores can survive bleach, boiling water, and flame scorching. The only reliable methods are gamma irradiation or burning. Contact your state apiarist for guidance before attempting to reuse any equipment from a suspected AFB colony.

How often should I replace my hive tools?

Hive tools last for years if you clean them properly. The issue is not wear but contamination. Clean and disinfect your hive tools after every use. If you cannot remove all wax and propolis from the tool, replace it. A hive tool with deep scratches and crevices is harder to disinfect than a smooth one.

What is the best disinfectant for beekeeping equipment?

A 10 percent bleach solution (1 part bleach to 9 parts water) is effective against most bacterial pathogens when applied for 10 minutes. Commercial beekeeping disinfectants are also available and may be less corrosive. Choose a disinfectant that is labeled for the pathogens you are targeting and follow the label instructions.

Can I share equipment between my apiary yards if I clean it between uses?

You can share equipment if you clean and disinfect it thoroughly between yards. The risk is that a quick wipe with a rag does not kill spores. Follow the full cleaning protocol: scrape, wash, disinfect, rinse, and dry. If you have any doubt about whether the equipment is clean, do not move it between yards.

How do I know if my bees have American foulbrood?

The classic symptoms are sunken and perforated brood cappings, dark greasy-looking cells, and a foul odor. When you probe a diseased larva with a toothpick, it stretches into a ropey brown thread. If you see any of these signs, contact your state apiarist immediately. Do not attempt to treat AFB yourself.

Should I quarantine queens before introducing them?

Yes. New queens should be introduced through a cage with their attendant workers. This gives the colony time to accept the queen and gives you time to observe her health. Watch for signs that the queen is rejected, such as the colony building queen cells or the queen being balled by workers.

What should I do if a colony dies during the winter?

Do not open the hive immediately. Wait until the weather warms, then inspect the colony carefully. Look for signs of disease, mite damage, or starvation. If you cannot determine the cause of death, contact your extension apiculturist or veterinarian. Clean and disinfect all equipment before reusing it.
