    Q
    You say 1 BTI Mosquito Dunk treats 100 sq ft of water. How many gallons are in 100 sq for of water?
    A

    BTI Mosquito Dunks treat the surface of the water, so because if this, the depth of water does not matter. They are placed in areas with standing water that are mosquito breeding sites.  As the briquets 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 mosquito larvae.

    Q
    Can you use water treated with BTI Mosquito Dunks to water your lawn?
    We have alot of gnats in our grass. When our dogs are outside laying down they are covered in them. Trying to find a non-harmful way to get rid of them.
    A

    BTI Mosquito Dunks are only meant to be used in standing water areas like bird baths, ponds, etc. If you wanted to treat your lawn for gnats you would want to use an actual insecticide like Bifen I/T which is a clear drying insecticide that would last on the lawn for at least 30 days to give continuous control over the gnat population and would be completely safe for your pet to lay on once dry. Bifen I/T is used at the rate of 0.5-1 oz per gallon of water and can be sprayed on lawns, bushes, trees, hedges, flowers, etc for gnat/mosquito control.

    Q
    Is it possible that deer are eating the BTI Mosquito Dunks?
    I keep putting dunks in my bird baths and they keep disappearing.
    A

    We really couldn’t say what is happening to the dunks honestly.  Per the product manufacturer of the BTI Mosquito Dunks the insecticidal toxins are a by-product of the bacillius thuringiensis in the dunks with is not harmful in any way to non-target animals.  So if they are eating the dunks it should not harm them.

    Can you use BTI dunks in a pond used for drinking water?
