HATCHING RELEASE BAGS
Every order includes hatching release boxes to keep Fly Wranglers (A.K.A. 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 Wranglers.
- Easy Introduction - Hatching Release Bags provide a contained environment for the hatching and dispersal of Fly Wranglers. These tiny parasitoids are smaller than an ant and can fly out of 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 Wranglers (A.K.A. Fly Exterminators) is a simple process. We also offer subscriptions so you can stay on top of the pest fly lifecycle.

For optimal results, release within 24 hours of hatching. Wait until temperatures are consistently over 50°F before releasing. Fly Wranglers will self-distribute up to 100 yards.
