Should I spray Bifen IT into standing water to get rid of mosquito larvae?

can I put this is standing water and will it dilute and kill mosquito larva? Or can I spray over still water and will it still be effective? or what do you recommend for still water? thanks

Answer:

You should not spray Bifen IT into standing water. You should use BTI Mosquito Briquette Dunks to treat standing water. BTI Mosquito Briquettes are a sustained-release larvicide that conveniently floats right on the water surface. These briquettes can be used in virtually any standing water site where mosquito larvae grow. As the briquettes float, BTI (or bacillus thuringiensis israelensis, a natural mosquito-killing biocontrol agent) is slowly released at the water’s surface and gradually settles in the water where it is consumed by mosquito larvae. Bti kills mosquito larvae before they are able to grow into mature, biting adults, eventually controlling the mosquito population. Additionally, the toxin will continue to be released into the water for a period of 30 days or more, providing continuous kill. Each briquette will effectively treat up to 100 square feet of surface water regardless of depth. Bifen can be used to help control adult mosquitoes on your property. Be sure to spray the undersides of leaves on trees as bushes as this is where mosquitoes like to hang out during the heat of the day.
