What Are Fly Wranglers?
Fly Wranglers are naturally occurring parasitoid insects. They are ant-sized predators that lay their eggs inside fly pupae found in manure, compost, and other decaying organic matter. Fly Wranglers eliminate the host pupa before an adult fly can emerge. This interrupts the fly life cycle at the pupal stage, targeting the population before it develops.
Fly Wranglers Are:
- Environmentally Friendly - Fly Wranglers minimize your fly problems naturally.
- Effective for a Variety of Animals - Protect your horses, cows, chickens, and more.
- Easy to Use - Simply scatter around fly breeding sites monthly.
How to Use Them
During warm months, apply Fly Wranglers near areas where flies breed, such as manure piles, compost areas, and other organic waste. Apply every three to four weeks to keep ahead of the pest fly lifecycle.

Testimonial
Phyllis B. Says:
"Fantastic! I tried everything to prevent the biting flies from tormenting my donkeys. Their legs would be bloodied by all the bites, in spite of the topical treatments and all the fly traps. This is a miracle for me and them. No more skin treatments. No my fly traps."
