Barn Fly Control for Small Barns and Stables
Family-run, licensed and insured pest control in South Florida.
$50 OFF your first service + FREE inspectionNew customers · No code needed · No expirationGood barn fly control starts with one fact: the flies in your barn were almost certainly born there, or very close by. A small barn with a few horses, goats or chickens produces exactly what flies need to breed, and in South Florida's heat they do it fast. Spraying alone can't keep up with that. What works is a mix of cleanup that takes away breeding spots and treatment of the places flies rest, done on a schedule that fits the barn.
Which flies are in your barn
Most barn flies are house flies and stable flies.
- House flies don't bite. They gather around manure, feed and trash, and on walls and ceilings in the sun. More on the house fly page.
- Stable flies look a lot like house flies but they bite, mostly on the legs. If your horses are stamping and switching their tails, stable flies are a likely reason.
Where barn flies breed
Both breed in wet, rotting material: manure mixed with bedding, wet hay, spilled feed and the muck under waterers. In South Florida heat, a house fly can go from egg to adult in as little as 7 to 10 days, and a stable fly in about two to four weeks. That's why a barn can look fine on Monday and be full of flies by the next weekend.
Common breeding spots to check:
- corners of stalls where wet bedding builds up
- the area under and around waterers and troughs
- the manure pile, especially the wet edges
- spilled feed and hay around the feeding area
- the wash rack drain and any spot where water pools
- trash cans and feed bags
How to get rid of flies in a horse barn: the cleanup side
This part is yours, and it makes the biggest difference:
- Clean stalls and wet spots often. Pull out wet bedding instead of covering it with fresh.
- Move the manure pile away from the barn, and keep it from spreading into wet areas.
- Fix leaking waterers and dripping hoses.
- Clean up spilled feed and old hay.
- Keep the wash rack draining. Standing water and wet dirt there breed flies and mosquitoes.
- Use tight lids on feed bins and trash cans.
Barn fly control: what we treat
Treatment works on the adult flies around the barn. Here's how we approach it:
- We start with an inspection of the barn, the manure area, the wash rack and the outside of the buildings.
- We treat the outside of the barn and the surfaces where flies rest: walls, overhangs, eaves and the shady areas around animal housing.
- We stay out of feed rooms and never spray animals directly. We don't treat pastures.
- Treatment is applied according to the label. Feed, water troughs and buckets are moved or covered first, and we'll tell you when animals can go back into treated areas.
Keep kids and pets off treated areas until dry, and follow your technician's instructions. For fly products that go on the horse itself, talk to your veterinarian.
Mosquitoes around the barn are a separate service. Our mosquito control page explains how we treat barn exteriors, paddock edges and wash racks, and the mosquito FAQ answers common questions.
A schedule that fits the barn
Barns get a flexible recurring schedule, set after the FREE inspection. Flies pick up in the warm, wet months, so many barns need more visits then than in the cooler, drier months. Options include monthly, bimonthly and quarterly service, and pricing for barns is quoted after the inspection. For plan customers: "If pests come back between visits, so do we, at no extra cost." There are no long-term contracts and no cancellation fees, just a simple service agreement. We're family-run and licensed, with 30+ years in the business, and hablamos español. See our commercial pest control and pest control pages, or our guides.
