How Fly Predators® Work

A step-by-step process on using fly predators®

Fly Predators® are the natural enemy of flies, but never bother people or animals. This is how the process works along with some quick tips for using your Fly Predators®.

Identify Your Needs
When ordering Fly Predators® we customize your order based on your needs. For every large animal, you will need approximately 1000 fly predators. We also factor in your location and climate.
Create Schedule
Get your recommended Fly Predator® schedule. Because pest flies reproduce nine times faster, adding supplemental Fly Predators® every three to four weeks during warm months keeps the population balance necessary for good fly control.
Get Your Shipment
We ship you your Fly Predators® in a safe package during their cocoon stage. Don’t open the bag until you see a dozen or more running around. This can take up to 2-7 days after they arrive.
Spread Your Predators
Once the Fly Predators® are ready, put them out within a day or two. They want to be where the pest flies reproduce, so sprinkle them out in moist areas such as manure. Once they are put out, your done! Repeat as necessary with your determined schedule.
