Spalding Fly Predators® brand beneficial insects are the natural enemy of flies, but never bother people or animals. They kill immature flies before they emerge by safe biological control. Every three to four weeks during fly season, just sprinkle them on all manure areas. It takes just a few minutes and you've done your fly control for the month.

Suitable for horses, cows, dogs, chickens, goats, sheep, alpacas and more.

Fly Predators are shipped directly from Spalding Labs every 2 to 3 weeks starting just as the temperatures reach the high 60's and stopping in the late Autumn.

Ask your Jeffers Customer Service Rep. for the optimum start and stop dates for your area.

For over 36 years, tens of thousands of livestock owners have depended on Fly Predators.

For best results, release Fly Predators
monthly for at least 3 months.

CANNOT BE SHIPPED TO CANADA!
