HATCHING RELEASE BAG

Every order includes hatching release bags to keep Fly Exterminators safely
out of reach from birds and rodents. Our hatching release bags are beneficial
for a number of reasons:
- Target Application - The Hatching Release Bags are designed to ensure controlled and targeted application of the Fly Exterminators.
- Easy Introduction - Hatching Release Bags provide a contained environment for the hatching and dispersal of Fly Exterminators. These tiny parasitoids are|smaller than an ant and can fit through the holes in the release bag after hatching.
- No Mess - Hatching release bags are designed to minimize cleanup efforts, eliminating the need for post-application cleanup or the handling of potentially messy substances.
Hang Hatching Release Bag out of direct sunlight. Height is not critical, but must be hung off the ground to protect from birds and rodents.
APPLICATION
Releasing Fly Exterminators is a simple process. We also offer subscriptions so you can stay on top of the pest fly lifecycle.
INTRODUCTION SITES
You may see large number 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 introduction sites include:
- Barns
- Stables
- Kennels
- Chicken Coops
- Feedlots
- Animal Straw Bedding
Other potential introduction sites include:
- Compost Piles
- Garbage Cans
- Septic Tanks
- Near Water Sources (but not directly in water)

Hatching may take 7-14 days, depending on temperature, with the Fly Exterminators beginning to hatch at 70°F. Pupae do not change in appearance after hatching. For optimal results, release within 24 hours of hatching. Wait until temperatures are consistently over 50°F before releasing. Fly Exterminators will self-distribute up to 100 yards.
- Locate fly breeding sites. Please see introduction sites above.
- Sprinkle Fly Exterminators near fly breeding sites and lightly cover to protect from birds and rodents OR sprinkle Fly Exterminators into hatching release bag and hang above the ground, away from birds and rodents.
