A natural way to control flies that is people, pet, and planet safe!
Protect your feathered and furry friends from fly borne diseases with our natural Fly Exterminators! Delivered in wood shavings, during the parasitized pupae stage (which looks like a black rice kernel) and ready to hatch, these nocturnal fly predators target the larval stage of various fly species, effectively minimizing the pest fly population. These tiny, ant-sized insects hover inches off the ground, and do not bite, sting, swarm, or bother humans or animals.
Fly Exterminators will begin hatching 7-14 days after delivery, depending on temperature. Reduction in fly population should be noticeable approximately 3 weeks after hatching.
Our Fly Exterminators are a predator to 95% of flies, including house flies, lesser houseflies, horse flies, filth flies, bot flies, biting stable flies, and various other fly species.
Less complete on the false stable fly, face fly, flesh fly, and horn fly since these species complete their life cycle widely dispersed in pasture.
You may see large numbers of flies around your animals, but the fly breeding area is most likely to be close to manure areas or other moist, rotting organic matter. These are the areas to release your Fly Exterminators.
Top priority release sites include barns, stables, kennels, chicken coops, on feedlots, and animal straw bedding.
Other potential fly breeding sites include compost piles, garbage cans, septic tanks, and near water sources (but not directly in water).
Release monthly during warm months. Heavy infestations may require additional releases.
- Locate fly breeding sites. Please see Release Sites section.
- Sprinkle Fly Exterminators near fly breeding sites and lightly cover to protect from birds and rodents.
- Locate other possible breeding sites and repeat.

- Locate fly breeding sites. Please see Release Sites section.
- Sprinkle Fly Exterminators in Hatching Bag (included). Secure the open edge with staples or clips to protect from birds or rodents. Hang it above the ground, away from direct sunlight, near fly breeding sites. The hanging height is not critical.
- Locate other possible breeding sites and repeat.
