This article is part of our Fly Control Awareness Month brought to you by Absorbine.

As the days get longer and the weather starts to warm up, horse owners anticipate the upcoming fly season. Taking proactive steps now can minimize the impact of flies before they become a persistent problem.
Proper preparation can lead to a more comfortable spring and summer for both horses and their owners. Here are some steps you can take to stay ahead of the fly season:

1. Start with a Clean Slate
Flies thrive in dirty environments, so reducing breeding grounds before flies have a chance to hatch is essential for effective fly control. Start by cleaning stalls, pastures, and paddocks. Regular manure management can significantly reduce fly populations before they become a problem. Cleaning stalls or runs daily can also help minimize fly presence near the barn.
If you have access to large pastures, spreading manure can fertilize them and prevent manure piles from attracting flies.
2. Set Up Your Fly Control Plan
There isn’t a one-size-fits-all approach to fly control, but a multi-layered plan can yield the best results. Consider using a combination of:
- Fly Sprays & Repellents: Use an effective, long-lasting fly spray preventively before flies appear.
- Fly Sheets & Masks: Protect your horse with fly sheets, fly boots, and fly masks to prevent irritation, especially for sensitive horses.
- Feed-Through Supplements: Some supplements disrupt the fly life cycle by affecting larval development in manure.
- Fly Traps & Predators: Natural solutions like fly traps and predators can help keep fly populations in check.
Stock up on these items in advance. Having fly control products on hand when flies start appearing will make your horse happier!
3. Prepare Your Barn & Turnout Areas
Proper airflow and moisture control can discourage flies from settling in your barn. Here are some quick fixes:
- Install fans in stalls and aisleways to create airflow that deters flies.
- Repair leaks and areas where water may accumulate.
- Place fly bait stations in areas where flies gather.
- Keep feed bins sealed and maintain a clean grain room to avoid attracting flies.
4. Monitor Early Fly Activity
Even if flies aren’t a major issue yet, noticing early signs of their presence can help you adjust your plan before they multiply. Watch for flies on manure piles, in shaded barn areas, or near water sources. If you see an increase, it’s time to step up your fly prevention efforts.
