Bt israeliensis is highly effective against mosquito larvae and black fly larvae. Bti comes in two forms: granular (Aquabac) and solid dunks. Both can be used wherever mosquitoes breed: the periphery of ponds, lakes, flooded orchards, ditches, pastures, sewage or animal waste lagoons, roof gutters, run-off areas, and so on.
The granular Bti should be broadcast at 2.5-10lbs/acre, every 7-14 days, depending on the organic properties of the water: black, murky water needs more than clear water. 10-20lbs/acre every 7-14 days may be needed to control 3rd & 4th instar larvae in highly organic waters.
The dunks kill mosquitoes for 30 days or longer when placed in standing water outdoors. As the dunks dissolve, the Bti settles in the water where it is eaten by mosquito larvae. Dunks can be anchored with string to prevent them from being washed away. Alternate drying and wetting does not reduce their effectiveness. Use 1 dunk/100 sq. ft. of infested water.
Bti does not harm people, pets, birds, fish, or plants. Dunks also can be used as a preflood treatment in areas expected to become breeding sources.
