Altosid XR Residual Briquets provide control over mosquito emergence up to 150 days in treated areas. These "ingot" shaped briquets contain the insect growth regulator (IGR) (S)-Methoprene. Altosid XR prevents the emergence of adult mosquitoes. However, it does not affect the mosquitoes that have reached the pupal or adult state.

For application sites connected by a water system,i.e., storm drains or catch basins, treat all of the water-holding sites in the system to maximize the efficiency of the treatment program
