How to Get Rid of Flies in a Chicken Coop

Flies can be a real nuisance in your chicken coop. They buzz around, annoy your flock, and can even spread disease. If you’re tired of swatting at them and want to give your poultry a more comfortable home, don’t worry—it’s a common problem with easy solutions!
In this guide, we’ll go over why flies love your coop and share some simple, practical steps to keep them away.
Why Are Flies Attracted to Chicken Coops?
First, let’s figure out why flies flock to your backyard chicken coop. Flies are pesky pests that no one likes. The main culprits of them finding their home in your hen coop are:
- Manure: Chicken droppings are a magnet for flies.
- Moisture: Wet bedding or spilled water creates the perfect breeding ground for flies.
- Food scraps: Leftover feed or treats can quickly attract flies.
By managing these factors, you can drastically reduce the fly problem.
Step 1: Keep It Clean
Flies thrive in dirty environments. Which is also why they bring in so many diseases. So cleaning the coop becomes your first line of defense. Here’s how:
- Remove Manure Daily
Scoop out droppings every day or as often as you can. Less manure means fewer flies. Use a small rake or scoop to make the task quick and easy. - Change Bedding Regularly
Wet or dirty bedding is a breeding ground for flies. Replace soiled bedding with fresh material weekly or more often if needed. - Clean Up Spills
If water or food spills, clean it up right away. Wet spots not only attract flies but can also cause mold and bad odors.
Step 2: Control Moisture
Flies love damp areas, so keeping the hen coop dry is essential.
- Fix Leaks: Check waterers for drips and repair any leaks.
- Improve Ventilation: Good airflow helps keep the coop dry. Make sure there’s enough ventilation without creating drafts.
- Cover the Run: If your run gets muddy after rain, consider adding a roof or tarp to keep things dry.
Step 3: Use Fly Traps
Fly traps are a simple way to reduce the fly population. You can buy them at a farm supply store or make your own.
- DIY Fly Trap: Fill a jar with a little apple cider vinegar and a few drops of dish soap. The vinegar attracts flies, and the soap traps them. Place the jar near the coop but out of reach of your chickens.
- Sticky Traps: Hang sticky fly paper in areas where flies gather, like near the coop entrance or above feeders. Just be sure to place them where chickens can’t get stuck.
Step 4: Try Natural Repellents
Flies hate certain smells, so natural repellents can help keep them away:
- Herbs: Plant fly-repelling herbs like mint, basil, and lavender around the coop. You can also hang bundles of these herbs inside the coop.
- Essential Oils: Mix a few drops of essential oils like eucalyptus, citronella, or peppermint with water in a spray bottle. Lightly spray the mixture around the coop (but avoid spraying it directly on your chickens).
Step 5: Use Fly Predators
Fly predators are tiny, non-stinging insects that feed on fly larvae. They’re completely safe for chickens and humans but deadly to flies. You can order them online and release them near the coop.
- How They Work: Fly predators lay eggs in fly larvae, stopping flies from hatching. It’s a natural, low-maintenance way to control flies long-term.
Step 6: Manage Food Sources
Flies are attracted to leftover food, so managing feed is important.
- Feeders: Use feeders that minimize spillage, like hanging feeders or ones with narrow openings.
- Scraps: Only offer as much food as your chickens will eat right away. Remove any leftovers quickly.
- Compost: If you compost chicken manure or food scraps, keep the compost pile far from the coop to avoid attracting flies.
Step 7: Lime and Diatomaceous Earth
These natural powders can help control flies and keep your coop fresh:
- Agricultural Lime: Sprinkle lime on the coop floor to dry out manure and discourage flies. Make sure to use safe, non-caustic lime specifically for agricultural use.
- Diatomaceous Earth (DE): Spread food-grade DE in the bedding and around the coop. It dries out fly larvae and keeps the environment less appealing to pests.
Step 8: Add Screens and Curtains
Flies can’t bother your chickens if they can’t get in!
- Screens: Install fine mesh screens over windows and vents to keep flies out while maintaining airflow.
- Curtains: Hang lightweight curtains over the coop entrance to block flies while allowing chickens to come and go freely.
Step 9: Rotate and Rest the Run
If your chicken run is heavily used, it can become a fly haven. Rotating the run area can help:
- Temporary Rest: Fence off a portion of the run and let it rest while your chickens use another area.
- Tilling: Turn over the soil in the resting area to bury fly eggs and larvae.
When to Call for Help
If you’ve tried everything and still have a major fly problem, it might be time to call a professional pest control service. Look for someone experienced in working with farm animals to ensure your chickens stay safe.
