Product Details

About Altosid® Larvicides

The Altosid family of products from Central Life Sciences are an effective mosquito larvicide option for professionals, providing consistent control and performance. Depending on the product form, residual control activity can range from 7 days all the way up to 150 days — giving mosquito control professionals peace of mind that they’re covered when needed most. Each Altosid® larvicide formulation contains (S)-methoprene, an insect growth regulator (IGR) that stops mosquitoes from becoming breeding, biting adults.

(S)-Methoprene is target-specific, has an excellent toxicity profile, 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 enjoy effective, long-term control.

Clarke is an authorized distributor of Altosid formulations for public health mosquito control use.
