With extended residual control, this granular insect growth regulator (IGR) is designed to prevent the emergence of adult mosquitoes, including those which may transmit vector-borne diseases like West Nile virus, Zika virus, Chikungunya and dengue. Altosid XR-G® kills mosquito larvae in stagnant water where they breed, including temporary or floodwater areas and irrigated cropland. Effective for up to 21 days, this formulation provides effective and flexible control—ideal for aerial applications in standing water over large tracts of land, ponds and lakes needing canopy penetration.

The same Altosid XR-G® granular formulation is offered in a 10 oz container called Altosid® Pro-G. This convenient size is ready-to-use, ideal for residents to apply at-home treatments to standing water on their property.
