Broiler House Rodent and Pest Control

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

Key Takeaways

Rodent and pest infestations in broiler houses lead to significant economic losses through feed contamination and consumption, structural damage (e.g., gnawed wiring causing ventilation failure), disease transmission (e.g., Salmonella, E. coli by flies and rodents), and food safety risks impacting processing.
Effective pest control relies on the integrated strategy of exclusion (sealing entry points with hardware cloth, caulk, steel wool), sanitation (immediate cleanup of spilled feed, managing litter moisture, proper feed storage), and population reduction (using a combination of snap traps, glue boards, and approved rodenticides in tamper-resistant bait stations).
Primary rodent threats include Norway rats (burrowing, prefer ground level), roof rats (climbing, prefer elevated nesting), and house mice (small, curious, prolific breeders), each requiring specific placement of traps and baits along established runways.
Flies (house flies, stable flies) and darkling beetles are significant vectors for pathogens like Salmonella and E. coli, with flies breeding in moist organic matter and beetles infesting litter; their control necessitates dry litter management and targeted insecticide applications.
Wild birds pose a critical biosecurity threat, acting as primary vectors for avian influenza and other serious diseases, necessitating strict exclusion through sealing all building envelope gaps and vents.
A robust monitoring system, including regular checks of bait stations and traps, coupled with meticulous recordkeeping of pest sightings and control actions, is essential for evaluating program effectiveness and identifying emerging issues.

Rodents, flies, wild birds, and crawling insects cost broiler growers real money every single day. They eat and contaminate feed, stress the birds, spread disease, damage buildings and insulation, and create food safety risks that can follow a flock all the way to processing. This guide covers the full range of pest problems in a broiler house and gives you practical, step by step methods for keeping them under control. It is written for broiler growers, farm managers, and poultry farm employees who want a cleaner, safer, and more profitable operation. You will learn how to identify the pests that matter, how to prevent them from entering, how to monitor their activity, and how to eliminate them using a combination of sanitation, exclusion, trapping, and approved chemical products.

Why Pest Control Matters in a Broiler House

A broiler house is an ideal habitat for pests. It is warm, humid, stocked with feed, and full of hiding places. Birds are confined in high densities, which means their feed and water are concentrated in a small area. Spilled feed accumulates under feeders and along walls. Litter provides warmth and cover. The structure itself, with its insulation, wall voids, and equipment, offers nesting sites for rodents and harborage for insects.

The financial impact of pest activity goes far beyond the cost of the feed they eat. Consider what happens when rodents gnaw through electrical wiring. A short circuit can shut down ventilation, heating, or lighting at the worst possible time. In a broiler house, ventilation failure can kill an entire flock in a matter of hours during hot weather. Rodents also gnaw through insulation, water lines, and feed lines. A single rat can cause thousands of dollars in damage in a single season.

Disease transmission is the other major concern. Rats and mice carry Salmonella, leptospirosis, and other pathogens. Flies mechanically transfer bacteria, viruses, and parasites from manure to feed and water. Wild birds can bring in exotic diseases like avian influenza, which can wipe out a flock and trigger a regulatory response from state and federal agencies. The USDA Animal and Plant Health Inspection Service, known as APHIS, treats certain poultry diseases as reportable emergencies. A wild bird entering your house is not just a nuisance. It is a potential biosecurity breach.

Food safety is the final piece. Processors inspect for evidence of rodent or insect contamination. If a load of birds shows signs of pest damage or if the processing plant finds rodent filth during inspection, you can lose your contract or face regulatory penalties. The modern broiler industry operates on thin margins. Pest control is not an optional expense. It is a core part of production.

Understanding Your Main Pests

Different pests require different control strategies. Before you can control a pest, you need to know what you are dealing with. This section covers the biology and behavior of the pests you will most commonly encounter in a broiler house.

Norway Rats

The Norway rat, also called the brown rat or sewer rat, is the most common rat on poultry farms. It is a large, heavy-bodied rodent that burrows in the ground. Norway rats are most active at night. They prefer to travel along walls and established runways. They are cautious about new objects in their environment, which means they may avoid bait stations and traps for several days after placement.

Norway rats are excellent diggers. They create burrows along building foundations, under concrete pads, and in dirt floors. A typical burrow has an entrance hole about 3 to 4 inches in diameter. The burrow system can extend several feet underground and has multiple entrances. Norway rats need water daily and prefer to nest within 100 to 150 feet of a water source. In a broiler house, the drinker lines and the humidity of the litter provide all the water they need.

Roof Rats

Roof rats are smaller and more agile than Norway rats. They are excellent climbers and prefer to nest above ground. You will find them in attics, ceiling voids, wall cavities, and on top of equipment. Roof rats are more common in warm coastal regions but can appear anywhere. They are less likely to burrow than Norway rats and more likely to enter a building through gaps in the roof, eaves, or utility penetrations.

Roof rats are also cautious about new objects. They tend to be more selective feeders than Norway rats. They may sample small amounts of bait one day and avoid it the next. This behavior makes them harder to control with poison baits alone.

House Mice

House mice are much smaller than rats. An adult mouse weighs less than an ounce. They can squeeze through openings as small as a quarter of an inch. Mice are curious and will investigate new objects, which makes them easier to trap than rats. They are also prolific breeders. A single female can produce 6 to 10 litters per year with 5 to 6 young per litter.

Mice do not need much water. They get most of their moisture from feed. They will nest in any protected spot, including inside insulation, under equipment, and in stacked materials. Their droppings are small, dark, and pointed at both ends. Mouse droppings are often the first sign of an infestation.

Flies

House flies and stable flies are the two most common fly pests in broiler houses. House flies breed in moist organic material, particularly in wet litter, spilled feed, and manure. The life cycle from egg to adult can be as short as 7 days in warm weather. This means fly populations can explode quickly.

House flies are a mechanical vector for disease. They land on manure, pick up bacteria, and then land on feed, water, equipment, and birds. They can carry Salmonella, E. coli, Campylobacter, and many other pathogens. Fly control is not just about comfort. It is about preventing disease transmission.

Stable flies are blood feeders. They bite birds and workers. Their bites are painful and cause stress, reduced feed intake, and reduced weight gain. Stable flies breed in decaying organic matter, particularly in wet litter and manure mixed with spilled feed. They are more common in houses with poor litter management.

Darkling Beetles

The darkling beetle, also known as the lesser mealworm, is a common beetle in broiler houses. It lives in the litter and feeds on spilled feed, manure, and dead birds. Darkling beetles are not just a nuisance. They carry Salmonella and other pathogens. They also damage insulation by burrowing into it. In heavy infestations, they can chew through foam insulation and cause significant structural damage.

Darkling beetles are most active at night. During the day they hide in litter, under feeders, and in cracks and crevices. Their larvae, called mealworms, are also found in the litter. Beetle populations build up over multiple flocks. A house with a long history of beetle problems will have a much larger population than a new house.

Wild Birds

Wild birds are a serious biosecurity threat to broiler houses. Sparrows, starlings, pigeons, and other birds can enter through open doors, damaged vents, and gaps in the roof. Wild birds carry avian influenza, Newcastle disease, and many other pathogens. They also eat and contaminate feed, leave droppings on equipment, and bring mites and other parasites into the house.

Excluding wild birds is a critical part of biosecurity. The World Organisation for Animal Health, known as WOAH, identifies wild birds as a primary reservoir for avian influenza viruses. Keeping them out of your house is one of the most important things you can do to protect your flock.

Step by Step Pest Control Program

A successful pest control program follows a logical sequence. You start with prevention, then add monitoring, and finally apply control measures when populations exceed thresholds. This section walks you through each step in order.

Step 1: Conduct a Thorough Farm Inspection

Before you can control pests, you need to know where they are coming from and how they are getting in. Walk the entire farm, including the outside of the house, the interior, and all adjacent buildings. Look for signs of pest activity and entry points.

Outside the house, look for rodent burrows along the foundation, under concrete pads, and near feed storage. Look for droppings near doors and along walls. Check for gnaw marks on doors, pipes, and wiring. Look for evidence of wild birds, including nests in eaves, droppings on ledges, and feathers near vents.

Inside the house, look for droppings along walls, under feeders, and in corners. Check the insulation for gnawing or tunneling. Look for grease marks along walls, which are caused by rodents rubbing against surfaces as they travel. Check the feed lines and drinker lines for leaks. Look for spilled feed under feeders and along the feed line. Check the litter for moisture and for signs of beetle activity.

Inspect the building envelope for gaps and openings. Rodents can squeeze through surprisingly small spaces. A mouse can fit through a hole the size of a dime. A rat can fit through a hole the size of a quarter. Check around pipes, wires, vents, and doors. Check the roof for gaps in the eaves and around the ridge cap. Check the side walls for gaps where the wall meets the foundation.

Step 2: Eliminate Entry Points

Exclusion is the most cost effective pest control measure you can take. It costs less than baiting and it works around the clock. Seal every gap and opening you find during your inspection.

For small gaps around pipes and wires, use expanding foam, caulk, or steel wool. Steel wool is important because rodents can chew through foam and caulk. Pack the gap with steel wool and then seal it with foam or caulk. For larger gaps, use hardware cloth, sheet metal, or cement.

Pay special attention to the area where the side wall meets the foundation. This is a common entry point for Norway rats. Fill any gaps with cement or mortar. Check the bottom of the doors and install door sweeps if needed. The sweep should fit snugly against the floor.

Check the ventilation system. Rodents can enter through the air inlets and exhaust fans. Install hardware cloth over the openings on the outside of the house. The mesh should be 1/4 inch or smaller to keep out mice. Use 1/2 inch mesh for rats. Make sure the mesh is securely attached and does not block airflow.

Check the roof for gaps where the roof meets the side walls and around the ridge cap. Wild birds can enter through gaps in the eaves. Install bird proofing material over these openings. Use metal flashing, hardware cloth, or specialized bird exclusion products. Do not use netting that birds can become entangled in.

Seal gaps around the feed bin and the auger system. Rodents can climb the feed bin legs and enter the house through the fill system. Install baffles or guards on the bin legs to prevent climbing. Check the seal where the auger enters the house.

Step 3: Remove Food and Water Sources

Pests will not stay where they cannot find food and water. Sanitation is the foundation of any pest control program. The cleaner your house, the fewer pests you will have.

Clean up spilled feed immediately. Spilled feed is the single most important food source for rodents, beetles, and flies. Sweep or vacuum around feeders daily. Adjust the feeder height to minimize spillage. The lip of the feeder should be at the height of the birds back. This reduces the amount of feed that is scratched out.

Check the drinker lines for leaks. Leaking drinkers create wet litter, which is a breeding ground for flies and beetles. Fix leaks promptly. Manage the litter to keep it as dry as possible. If the litter becomes wet, add fresh dry litter or remove the wet spots.

Store feed properly. Keep the feed bin closed and in good repair. Clean up any feed that spills around the bin. Do not leave open bags of feed in the house or in the feed room. Store all feed in sealed containers.

Remove debris and clutter. Piles of lumber, old equipment, and trash provide harborage for rodents. Remove or elevate anything that is stored outside. Keep the area around the house mowed and free of weeds. Tall grass and weeds provide cover for rodents and make it easier for them to move around undetected.

Step 4: Set Up a Monitoring System

You cannot control what you do not measure. A monitoring system tells you where pests are active, how many there are, and whether your control measures are working.

Place monitoring stations around the perimeter of the house, inside the house, and at all entry points. Use bait stations, snap traps, or glue boards. The purpose of monitoring is not just to kill pests. It is to give you information. Check the stations regularly and record what you find.

For rodents, place bait stations every 50 to 100 feet along the outside walls of the house. Place additional stations near the feed bin, at the corners of the house, and near any known entry points. Inside the house, place stations along the walls, under feeders, and in corners. Rodents prefer to travel along walls, so place stations with the opening parallel to the wall.

For flies, use sticky fly tape or fly traps to monitor population levels. Place them near the entrance, near the feeders, and in areas where flies are most active. Check the traps weekly and record the number of flies caught.

For darkling beetles, use pitfall traps or simply inspect the litter regularly. Lift the litter in several spots and look for beetles and larvae. Record the number you find. A threshold of 10 to 20 beetles per square foot in the litter indicates a serious infestation that requires treatment.

Step 5: Choose Your Control Methods

Once you know what pests you have and where they are active, you can choose the appropriate control methods. A combination of methods is almost always more effective than any single method.

Rodent Control Methods

Snap traps are the most reliable method for killing rodents. They are quick, humane, and allow you to confirm that you have killed the rodent. Use large snap traps for rats and small snap traps for mice. Bait the traps with peanut butter, bacon, or a piece of dried fruit. Place the traps along walls with the trigger end against the wall. Check the traps daily and reset them as needed.

Glue boards are useful for monitoring and for catching rodents in areas where traps are impractical. Place them along walls and in corners. Glue boards are not a humane method of control because rodents may struggle for hours before dying. Check them daily and dispose of any captured rodents promptly.

Rodenticides, or poison baits, are effective when used correctly. Use only approved bait products and follow the label instructions exactly. Place bait in tamper resistant bait stations to prevent access by children, pets, and non target animals. Secure the stations to the ground or to a wall so they cannot be moved.

Rodenticides come in two main types. Anticoagulant baits work by preventing blood clotting. They require multiple feedings over several days. A single feeding may not be lethal. Non anticoagulant baits, such as bromethalin, work more quickly and can be lethal after a single feeding. Choose the product that best fits your situation.

Important note on bait shyness. Rats are cautious about new food sources. If you use the same bait for a long time, rats may become wary of it. Switch to a different bait product periodically to keep the population from becoming bait shy. This is especially important for roof rats, which are naturally cautious feeders.

Fly Control Methods

Fly control requires an integrated approach. Sanitation is the most important component. Remove the breeding sites and you remove the flies. Wet litter, spilled feed, and manure are the primary breeding sites. Keep the litter dry, clean up spills, and manage the manure properly.

Insecticide sprays can knock down adult fly populations quickly. Use a residual spray on walls, ceilings, and other resting surfaces. Use a space spray, also called a fogger, to kill flying adults. Follow the label instructions for application rates and safety precautions. Do not spray feed, water, or birds directly.

Fly baits are another option. These are granular or liquid products that attract flies and kill them when they feed. Place fly baits in trays or scatter them in areas where flies congregate. Keep fly baits away from birds and feed.

Biological control is an emerging option. Parasitic wasps are tiny beneficial insects that lay their eggs in fly pupae. The wasp larvae consume the developing fly and kill it. These wasps are available commercially and can be released regularly to help control fly populations. They are not harmful to people, birds, or other animals.

Darkling Beetle Control

Darkling beetles are difficult to control because they live in the litter and reproduce rapidly. The most effective control is a combination of litter management and chemical treatment.

Keep the litter dry. Darkling beetles prefer moist litter. Fix leaks, improve ventilation, and remove wet spots. Between flocks, remove the litter completely if the beetle population is high. This removes the majority of the beetles and their larvae.

Chemical treatments are available for darkling beetles. These are applied to the litter or to the walls and floor before the birds arrive. Some products are labeled for use in poultry houses. Follow the label instructions carefully. Pay special attention to the withdrawal period, which is the time between treatment and the arrival of the birds.

Several products contain insecticides that are effective against darkling beetles. Look for products containing cyfluthrin, tetrachlorvinphos, or other approved active ingredients. Rotate between different classes of insecticides to prevent resistance.

Wild Bird Control

Exclusion is the primary method for wild bird control. Seal all gaps in the roof, eaves, and vents. Keep doors closed when they are not in use. Install bird netting over open areas where birds can enter.

If wild birds are roosting or nesting on the building, use deterrents to discourage them. Bird spikes can be installed on ledges and roof ridges. Visual deterrents, such as predator decoys or reflective tape, can be effective for a short time. Birds become accustomed to these deterrents, so they need to be moved or changed regularly.

Auditory deterrents, which emit distress calls or predator sounds, can be effective but may also disturb neighbors and workers. Use them with caution and follow any local regulations.

Shooting is an option for small populations of pest birds, but it is not practical for large infestations. Check your local regulations before using this method. Some species of wild birds are protected by law.

Step 6: Treat the Perimeter

Pest control does not stop at the walls of the house. The area around the house is a reservoir for pests. If you do not treat the perimeter, pests will continue to re enter the house.

Keep the area around the house clean and free of debris. Mow the grass regularly. Remove any piles of lumber, equipment, or trash. Keep the area around the feed bin clean and free of spilled feed.

Maintain a gravel barrier around the foundation. A strip of gravel 2 to 3 feet wide creates a dry, open area that rodents do not like to cross. It also makes it easier to see rodent activity.

Place bait stations around the perimeter of the house. These should be checked and refilled on a regular schedule. Use a permanent bait station program. Rodents will constantly try to re establish themselves around the farm. A continuous baiting program keeps the population in check.

Step 7: Coordinate With Your Flock Schedule

Pest control activities should be coordinated with the flock schedule. The period between flocks, when the house is empty, is the best time for intensive pest control.

During the downtime, remove all litter and clean the house thoroughly. This removes the breeding habitat for flies and beetles. Repair any damage caused by rodents. Seal any new entry points. Apply residual insecticides to the walls and floor to control beetles. This is also the time to clean and repair bait stations and traps.

Do not forget to treat the outside of the house during downtime. The area around the house should be cleaned and treated just like the inside. Rodents will move from the outside to the inside when the new flock arrives. Reduce the outside population before that happens.

Step 8: Train Your Workers

Pest control is not a one person job. Everyone who works on the farm needs to understand the pest control program and their role in it. Train your workers to recognize the signs of pest activity. Teach them to report any sightings immediately. Show them how to check and maintain traps and bait stations.

Make sanitation a daily habit. Workers should clean up spilled feed, fix leaks, and keep the house tidy as part of their regular routine. Pest control is much easier when everyone is working together.

Keep a pest control log book in a central location. Workers should record any pest sightings, any traps that were triggered, and any bait that was consumed. This log provides the data you need to evaluate your program and make adjustments.

Common Mistakes in Broiler House Pest Control

Even experienced growers make mistakes in pest control. Here are the most common ones and how to avoid them.

Relying on Poison Baits Alone

Poison baits are an important tool, but they are not a complete program. Baits kill rodents that consume them, but they do nothing to prevent new rodents from entering the house. If you rely on baits alone, you will be fighting a constant battle. Combine baiting with exclusion, sanitation, and trapping for the best results.

Placing Traps and Baits in the Wrong Locations

Rodents travel along walls and established runways. They do not wander around in the open. Place traps and bait stations with the opening parallel to the wall. Place them in areas where you have seen droppings, gnaw marks, or other signs of activity. A trap placed in the middle of the room will catch nothing.

Not Checking Traps and Bait Stations Frequently Enough

Traps and bait stations need to be checked regularly. Snap traps should be checked daily. Bait stations should be checked at least weekly. Glue boards should be checked daily. If you do not check your devices, you will not know if they are working. A trap that is not set or a bait station that is empty is useless.

Using the Wrong Bait

Different rodents prefer different foods. Norway rats prefer meat and fish. Roof rats prefer fruits and nuts. House mice prefer seeds and grains. Peanut butter is a good all purpose bait, but you may need to experiment to find what works best in your situation. If rodents are avoiding your traps, try a different bait.

Ignoring the Outside of the House

Pest control inside the house is only half the battle. If you do not control pests outside, they will keep coming inside. Treat the perimeter, keep the area clean, and maintain bait stations around the outside of the house.

Not Keeping Records

You cannot evaluate your pest control program if you do not have records. Keep a log of all pest sightings, all control actions, and all results. This data helps you identify problem areas, track population trends, and make informed decisions about your program.

Using Expired or Improperly Stored Products

Pesticides and rodenticides have a shelf life. Check the expiration date before using any product. Store products in a cool, dry place away from direct sunlight. Do not use products that are expired or that have been stored improperly.

Not Following Label Instructions

The label is the law. Every pesticide and rodenticide product has a label that specifies how it should be used, where it can be used, and what safety precautions are required. Read the label before using any product. Follow the label instructions exactly. Using a product in a way that is not specified on the label is illegal and unsafe.

How to Know When Your Pest Problem Is Serious

Not every pest sighting requires a full scale response. A few flies in the summer are normal. A single mouse that got in through an open door is not an emergency. But there are thresholds that indicate a serious problem that requires immediate action.

Rodent Thresholds

If you see rodents during the day, you have a serious infestation. Norway rats and house mice are nocturnal. Seeing them in daylight means the population is so large that they are being forced out of their hiding places. This is a sign that you need to take immediate action.

If you find multiple fresh droppings in several locations, you have an active infestation. If you find gnaw marks on wiring, insulation, or equipment, the rodents are causing damage. If you find rodent burrows along the foundation, you have a breeding population.

Fly Thresholds

Fly populations can be measured using sticky traps. A general guideline is that if you are catching more than 100 flies per sticky trap per week, you have a problem that needs attention. If flies are bothering the birds or the workers, the population is too high. If you see fly larvae, called maggots, in the litter, you have an active breeding site that needs to be addressed.

Darkling Beetle Thresholds

Inspect the litter in several locations. If you find more than 10 beetles per square foot, you have a serious infestation. If you see beetles climbing the walls or congregating around feeders, the population is high. If you find damage to insulation, the beetles have been present for a long time.

Wild Bird Thresholds

Any wild bird inside the house is a problem. Wild birds are a biosecurity risk, regardless of the species. If you see wild birds entering the house, take immediate action to exclude them. If you find nests or droppings inside the house, you have an ongoing problem that requires immediate attention.

Monitoring and Recordkeeping

A pest control program is not a set and forget system. It requires ongoing monitoring and regular adjustments. The data you collect through monitoring tells you what is working and what is not.

What to Record

Keep a pest control log book or use a digital spreadsheet. Record the following information on a regular basis:

Date and time of inspection
Pest species observed
Location of pest activity
Number of pests observed
Condition of traps and bait stations
Amount of bait consumed
Control actions taken
Results of control actions

How Often to Monitor

Check traps and bait stations weekly at minimum. Check more frequently during periods of high pest activity or after control actions. Walk the perimeter of the house weekly to look for new burrows, droppings, and entry points. Inspect the interior of the house weekly for signs of pest activity.

Using Your Records

Review your records monthly to identify trends. Are pest sightings increasing or decreasing? Are certain areas of the farm more problematic than others? Are certain control methods more effective than others? Use this information to adjust your program.

If you see a sudden increase in pest activity, investigate the cause. Look for new entry points, new food sources, or changes in the environment. A spike in pest activity often indicates a problem that needs to be fixed.

When to Call a Veterinarian or Extension Agent

Most pest control problems can be handled by the farm crew. But there are situations where you should call for professional help.

Signs of Disease

If you see signs of disease in your flock, call your veterinarian immediately. Sudden increases in mortality, respiratory distress, swelling of the head or face, purple discoloration of the combs or wattles, and sudden drops in feed or water consumption are all signs that require immediate attention. Some of these signs, particularly sudden death and respiratory distress, can indicate a reportable disease such as avian influenza or Newcastle disease.

The USDA APHIS and the World Organisation for Animal Health, known as WOAH, have strict reporting requirements for certain poultry diseases. Your veterinarian will know the reporting requirements in your area. Do not wait to see if the problem resolves on its own.

Pest Infestations You Cannot Control

If you have a pest infestation that you cannot control with your own efforts, call a professional pest control operator or your extension agent. A licensed professional can identify the pest species, assess the extent of the infestation, and recommend appropriate control measures. They may have access to products that are not available to the general public.

Unusual Pest Activity

If you see pests that you do not recognize or if you see unusual behavior in known pests, contact your extension agent. There may be a new invasive species in your area that requires a different control approach.

Regulatory Concerns

If you suspect that a reportable disease has entered your flock, contact your veterinarian or state animal health official immediately. Do not attempt to diagnose or treat the disease yourself. Early reporting can help contain the disease and prevent it from spreading to other farms.

Frequently Asked Questions

How often should I check my rodent bait stations?

Check bait stations at least once a week. During periods of high rodent activity, check them more frequently. Each time you check, record the amount of bait consumed and any signs of rodent activity. Refill the stations as needed. A station that is empty for several days is not doing its job. Also check the stations for damage and make sure they are still securely anchored and tamper resistant.

What is the best bait for rats in a poultry house?

There is no single best bait that works in every situation. Norway rats prefer meat and fish based baits. Roof rats prefer fruits and nuts. Peanut butter is a good all purpose bait that works well in most situations. You may need to experiment to find what works best in your house. If you are using poison baits, choose a product that is labeled for use in poultry houses and follow the label instructions. Rotate between different bait types to prevent bait shyness.

Can I use cats to control rodents in a broiler house?

Cats can help control rodents, but they are not a substitute for a proper pest control program. Cats are not allowed in many commercial poultry operations because they can carry diseases and may disturb the birds. A cat may catch some mice, but it will not eliminate the population. Cats cannot get into the wall voids and other hiding places where rodents live. They also do not prevent new rodents from entering the house. Use cats as a supplement to, not a replacement for, traps, baits, and exclusion.

How do I keep flies out of my broiler house?

The most important step is to remove fly breeding sites. Flies breed in moist organic material, including wet litter, spilled feed, and manure. Keep the litter dry, clean up spilled feed immediately, and manage the manure properly. Install fly screens over vents and openings to keep flies out. Use sticky traps and insecticide sprays to control adult flies. Consider using parasitic wasps as a biological control method. A comprehensive approach that combines sanitation, exclusion, and control measures is the most effective way to manage flies.

What should I do if I find a wild bird inside my broiler house?

Remove the bird immediately and humanely. Wear gloves and use a net or other tool to capture the bird. Do not handle it with bare hands. After removing the bird, inspect the house for how it got in and seal the entry point. Check the rest of the house for other wild birds. Wild birds are a serious biosecurity risk because they can carry avian influenza and other diseases. If you find evidence of wild bird activity, such as nests or droppings, take immediate action to exclude them. If you have any concerns about disease exposure, contact your veterinarian.

How do I get rid of darkling beetles in my broiler house?

Darkling beetles are difficult to control because they live in the litter and reproduce rapidly. The most effective approach is to remove the litter between flocks and clean the house thoroughly. Apply an approved insecticide to the walls and floor before the new flock arrives. Keep the litter as dry as possible during the flock. Fix any leaks and improve ventilation to reduce moisture. If the beetle population is high, you may need to treat the litter with an approved product. Rotate between different insecticide classes to prevent resistance.

What is the best way to prevent rodents from entering my broiler house?

Exclusion is the most effective method. Seal every gap and opening around pipes, wires, vents, and doors. Install door sweeps on all exterior doors. Fill gaps in the foundation with cement or mortar. Install hardware cloth over ventilation openings. Keep the area around the house clean and free of debris. Maintain a gravel barrier around the foundation. Place bait stations around the perimeter to catch any rodents that do get through. A combination of exclusion, sanitation, and perimeter baiting is the most effective approach.

How do I know if my pest control program is working?

The best way to evaluate your pest control program is to track your monitoring data over time. If you are seeing fewer pests, less bait consumption, and fewer signs of activity, your program is working. If pest activity is staying the same or increasing, you need to adjust your approach. Review your records monthly to identify trends. If you are not seeing improvement, consider consulting a professional pest control operator or your extension agent for advice.

Is it safe to use rodenticides in a broiler house?

Rodenticides are safe when used correctly. Always use tamper resistant bait stations to prevent access by children, pets, and non target animals. Follow the label instructions exactly. Do not place bait where birds can access it. Secure the bait stations so they cannot be moved. Check the stations regularly and dispose of any dead rodents promptly. If you have any concerns about safety, consult the product label or your extension agent.

When should I call a professional pest control operator?

Call a professional if you have a pest infestation that you cannot control with your own efforts. This includes large rodent populations, persistent fly problems, or darkling beetle infestations that do not respond to treatment. A professional can assess the situation, identify the pest species, and recommend appropriate control measures. Call a professional immediately if you suspect a reportable disease in your flock. Do not wait to see if the problem resolves on its own.
