If you're wondering how to get rid of flies around your chicken coop, the good news is that the fix is usually simpler than you'd think: keep things clean and dry. Flies aren't drawn to your hens themselves but to the conditions a coop can create — droppings, moisture, spilled feed, and damp bedding. Sort those out and the swarms thin out fast.
Short answer: Remove droppings often, keep bedding and the run dry, clean up spilled feed and leaking water, improve drainage and ventilation, and back it up with natural deterrents and a few well-placed fly traps. A smooth, easy-clean coop and removable droppings trays make that routine far quicker.
Why do chickens attract flies?
Chickens don't attract flies on purpose — their environment does. Understanding why coops draw flies is the first step to stopping flies in your chicken run. Here are the main culprits.
1. Manure and droppings
Chickens produce a lot of moist droppings, rich in nutrients and organic material. That makes accumulated manure the single most attractive breeding ground for flies around any coop. The faster you remove it, the fewer flies you'll see.
2. Spilled feed
Chickens often spill and trample their feed. Scattered grain and any decomposing organic matter on the ground are powerful fly magnets, so tidy feeding habits matter for chicken coop fly control.
3. Moisture and poor drainage
Waterers spill and leak, creating damp patches. Flies thrive in moist environments, so any wet spots around the run will boost their numbers. Good drainage and dry bedding are two of your strongest weapons against flies.
4. Damp bedding and run material
Organic run material like wood chips, and bedding inside the coop, slowly decompose and collect droppings. Once they turn damp, they become an ideal place for flies to breed. Keeping bedding dry and refreshing run material regularly cuts that breeding cycle short. (For more on this, see our guide to the best bedding for chicken coops.)
5. Warmth
The warmth from your birds and their bedding accelerates the fly life cycle, letting them reproduce rapidly in summer. You can't change the weather, but you can deny them the damp, dirty conditions they need.
6. Other pets, livestock, compost, and ponds
Flies rarely have a single source. Other animals' waste, an open compost bin, and nearby ponds all add to the population — so your chickens often get blamed for the cumulative effect of the whole yard. Lidding the compost and managing standing water help more than you'd expect.
None of these factors alone is the reason you have flies. And while flies are annoying, they pose little risk to your hens. Before you tear up half your yard, there are much easier ways to manage the situation.
How to get rid of flies around your chicken coop
Unlike parasites such as red mites, flies are more of a nuisance to us than to our birds. The real fix is keeping everything clean and dry — everything else is a useful backup. Here's how to stop flies in your chicken run, in roughly the order of impact.
- Clean the coop and remove droppings often. This is the most effective fly control there is. Clean the coop at least weekly — more in hot weather — removing soiled bedding and scrubbing perches and the ramp, which get grubby fast. A Nestera coop is easy to wash out and dries quickly in warm weather (or even faster with a towel). Better still, pull-out droppings trays let you lift out the worst of the mess in seconds, so manure never gets the chance to attract flies.
- Keep bedding and the run dry. Damp is what turns bedding into a fly nursery. Refresh bedding before it gets soggy, fix any roof or wall leaks, and make sure the run has good drainage so it dries out after rain.
-
Manage feed and water spills. Use a feeder that prevents spillage and put feed away at night. Make sure waterers don't leak and sit where spills can drain away quickly; nipple drinkers minimize wasted water and wet patches.
- Replace old run material. If the run has old, decomposing chips, dig them out, add them to a lidded composter, and lay fresh material. Your birds get something new to scratch through, and you remove parasitic worm eggs and other pathogens in the process.
- Lid your compost. Use compost bins with tight lids for manure, yard waste, and food scraps so flies can't reach them.
- Good ventilation. A well-ventilated coop dries out faster and stays less hospitable to flies. Fine mesh screens on windows and vents keep flies out while air still flows freely.
-
Fly traps. Use commercial or homemade traps around the coop and run. Sticky traps, baited water, baited cage traps, and UV light traps all work. Place baited traps as far from people and birds as you can — they don't smell great!
- Natural deterrents. Plant fly-repellent herbs such as basil, lavender, mint, and marigolds around the coop. You can also mix 10–15 drops of essential oil with a cup of water in a spray bottle, shake well, and spray fly-prone areas. Flies particularly dislike lavender, peppermint, eucalyptus, lemongrass, tea tree, citronella, basil, clove, and rosemary oils.
- Beneficial insects and predators. Parasitic wasps prey on fly larvae and can naturally lower fly numbers, and encouraging wild birds and frogs that eat flies helps too.
How an easy-clean coop makes fly control faster
Every method above comes back to one thing: keeping the coop clean and dry. That's far easier when the coop is built for it. Nestera coops are made from 70% recycled plastic with smooth, non-porous surfaces that wipe down and rinse out in minutes — no flaky wood or crevices for muck to cling to. Large rear hatches and removable roofs give you full access, and pull-out droppings trays let you clear away manure daily without a full clean-out.
Because hygiene is so quick, you're far more likely to keep up the frequent cleaning that actually stops flies breeding. Smooth plastic also leaves nowhere for red mites to hide, which is a welcome bonus. If you're looking at coops, a wipe-clean recycled-plastic chicken coop takes a lot of the work out of staying fly-free. It pairs naturally with good habits like regular dust baths for healthy plumage and smart feed storage to keep wildlife (and flies) away from spilled grain.
Frequently asked questions
Why do chickens attract flies?
Chickens themselves don't attract flies — their droppings, spilled feed, damp bedding, and any wet, decomposing material around the coop do. Flies are drawn to moisture and organic waste, so a clean, dry coop attracts far fewer.
Are flies harmful to my chickens?
Flies are mostly a nuisance to people and pose little risk to healthy hens. That said, heavy fly numbers can spread some pathogens and lead to problems like flystrike. If your birds seem unwell or you spot wounds or maggots, contact your vet or a qualified poultry specialist.
What's the fastest way to stop flies in a chicken run?
Remove droppings and clean the coop more often, keep bedding and the run dry, and clear up spilled feed and leaking water. Removing the breeding sources works faster and more reliably than any trap or spray on its own.
Do natural fly repellents really work for coops?
Herbs like lavender, mint, and basil and essential-oil sprays can help deter flies and are a good supplement, but they won't fix the root cause. Use them alongside frequent cleaning and dry bedding, not instead of it.
The bottom line: get rid of flies around your chicken coop by keeping it clean and dry, and make that routine effortless with an easy-clean, wipe-down coop. Explore the Nestera recycled-plastic chicken coop and matching droppings trays to keep hygiene quick and your flock fly-free.
