Altosid® Pellets

Professional Products

No two mosquito habitats are alike - and neither are the ways you treat them. That's why there are a variety of Altosid formulations. Each provides the extended control you need in easy-to-access or difficult-to-treat areas. Altosid formulations are labeled for use in known fish habitats. That means they prevent the emergence of breeding, biting adults without upsetting the food chain or impacting non-target species. So you're ensured consistent control - and peace of mind. TARGET - SPECIFIC CONTROL: Unlike conventional pesticides, each Altosid® formulation contains (S)-methoprene, an insect growth regulator (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. Altosid Pellets provide up to 30 days of residual control in standing water.
