Mosquito Growth Regulators

Insect/Mosquito growth regulators (IGR's) stop mosquitoes from becoming breeding, biting adults. (S)-Methoprene is target-specific and will not affect fish, waterfowl, mammals or beneficial predatory insects. As a result, you can feel comfortable using (S)-Methoprene IGR's in your district's most sensitive areas. And you'll feel even better about the effective, long-term control you'll get in return.


Best of all, our (S)-methoprene products like Altosid have an excellent toxicity profile. So you get complete control without additional worries. Furthermore, residual larvicidal activity reduces adult populations and the need for adulticides.
