Frequently Asked Question

Btk is not a chemical insecticide, rather it is a naturally occurring organism. Chemical pesticides have a single mode of action (making them susceptible to insecticide resistance) and typically kill a wider range of insects, including many beneficial ones. The active ingredient of Foray is a natural bacterium, Bacillus thuringiensis, spp. kurstaki Strain ABTS-351. This strain of Btk produces a finely balanced profile of four different protoxins specific to the larvae of certain caterpillars.

This means that non-targets (birds, bees, fish, people) are unaffected by Foray. Foray is quickly biodegraded in nature, unlike a number of chemical pesticides that form by-products and residues of environmental concern. Most formulations of Foray are approved in Certified Organic programs.
