On June 3, 2026, the U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) confirmed the detection of a New World screwworm (NWS) in Texas.

The U.S. food supply is safe. Screwworms do not infest meat, fruits, vegetables, or other food sources.

New World screwworm has not been found in the US at this time. However, it is important to know the facts about how it could affect livestock, pets, wildlife and people.

New World screwworm is NOT in the U.S. and the U.S. Department of Agriculture continues to deploy proven technology and nationwide outreach to stay ahead of this pest and protect livestock, pets, wildlife, and people.

Preparedness starts with awareness, so get the facts:https://www.aphis.usda.gov/sites/default/files/nws-myth-busters.pdf

Take a look at this information about Environmental Insect Management.

American Association of Equine Practitioners

Practical environmental management steps can make a big dent in insect populations around horse farms, often without needing pesticides. 🪰🦟

🦟 REDUCE MOSQUITO BREEDING
• Dump standing water routinely.
- Mosquitoes need water to complete their life cycle. Empty water that collects in flowerpots, buckets, barrels, etc.
- Drill drainage holes in tire swings and keep children’s wading pools empty and stored on their side when not in use.
• Refresh water troughs frequently. Change water troughs at least twice weekly to discourage mosquito breeding.
• Mosquito-proof barns and stables:
- Install and maintain secure screens on windows and doors.
- Use fans (mosquitoes/flies avoid strong air movement because they can’t control flight well).
- Consider lighting choices. In barns, swapping incandescent bulbs for fluorescent-type fixtures can make the area less attractive to mosquitoes.

🪰 SANITATION & FACILITY MANAGEMENT
• Manure and waste handling (sanitation) is foundational. Remove stall and paddock litter and dispose of it properly.
• Stacking manure to reduce surface area is recommended; for small facilities, covering stacks with plastic film can help reduce fly breeding.
• If hay is fed in paddocks, avoid allowing hay to get trampled into the footing/substrate near feeders—flies can develop in that material, sometimes even beneath the soil surface.

⚠️ REMEMBER: not all flies come from your manure pile. “Feed-through” fly products are only potentially helpful if the flies are actually breeding in manure from horses on-site; in contrast, face flies, horn flies, and tabanids do not breed in horse manure, while house flies and stable flies can.

TRAPS & NON-CHEMICAL TOOLS
• Use traps to monitor and help manage flies. Traps can be useful to track fly numbers, but placement matters.
- Put traps where flies are numerous, and for stable flies, as close to the animals as possible.
• Use fans inside barns as pesticide-free protection. This is one of the simplest, most effective barn strategies for flies that enter.
• UV light traps can help indoors. If used, they’re recommended inside barns; avoid placing them outside or running them after dark.
