Fly Control

Filth flies breed faster than you can spray, and they build resistance just as fast. Fly parasites stop them before they ever take wing — quietly, around your animals and crew.

House and stable flies pour out of manure, bedding, and damp organic matter all season. Fly parasites for fly control are tiny beneficial wasps that destroy fly pupae at the source, so biological fly control shrinks the population without sprays or residue.

Why choose biological fly control

Filth flies resist insecticides and breed continuously, but fly parasites attack the pupal stage where flies concentrate — leaving no residue and staying completely safe around livestock, pets, and handlers.

How to build your program

Scatter fly parasites near manure, bedding, and moist breeding sites every few weeks through fly season, or use a hatching station for steady emergence. Pair releases with sanitation and moisture control for the biggest knockdown.

What's in this collection

• Fly Parasites — beneficial wasps that parasitize house and stable fly pupae.
• Fly Parasite Hatching Station — protects and releases parasites for continuous control.

Frequently asked questions

How do fly parasites work?

The tiny wasps lay eggs in fly pupae; the developing parasite kills the pupa, so a new wasp emerges instead of a fly.

Are fly parasites safe around livestock?

Yes — they target only fly pupae, don't sting or bother animals or people, and leave no chemical residue.

When should I start releasing fly parasites?

Begin early in the season before flies build up, and re-release every 2–4 weeks to stay ahead of breeding.

Will fly parasites get rid of all my flies?

They dramatically reduce the breeding population over time; combine them with sanitation and traps for the cleanest results.
