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.
Application Altosid XR Residual Briquets
Place these briquets in areas before flooding when sites are dry or on snow or ice. Alternate wetting or drying will not reduce effectiveness.
Examples of application sites are: storm drains, catch basins, roadside ditches, fish ponds, ornamental ponds and fountains, other artificial water-holding containers, animal watering troughs, cesspools, and septic tanks, waste treatment and settling ponds, flooded crypts, transformer vaults, abandoned swimming pools, tires, construction and other man-made depressions, cattail marshes, water hyacinth beds, vegetation-choked phosphate pits, pastures, meadows, rice fields, freshwater swamps and marshes, salt and tidal marshes, tree holes, woodland pools, floodplains, and dredging spoil sites. 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
Aedes, Ochlerotatus,andPsorophoraspp.:For control non-(or low-) flow shallow depressions (<2 feet in-depth), treat based on the surface area, placing one Altosid Briquet per 200 ft2. Place briquets in the lowest areas of mosquito breeding sites to maintain continuous control as the site alternately floods and dries up.
Culex, Culiseta and Anophelesspp.:Place one Altosid XR Briquet per 100 ft2.
Coquillettidia and Mansoniaspp.: For application to cattail marshes and water hyacinth beds. For control of these mosquitoes, place one Altosid XR Briquet per 100 ft2
