Unlike conventional pesticides, each Altosid® formulation contains (S)-methoprene, an insect growth regular (IGR) that stops 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 Altosid® 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, the (S)-methoprene in Altosid® products has an excellent toxicity profile. So you get complete control without additional worries. Furthermore, residual larvicidal activity reduces adult populations and the need for adulticides.
