Kills Mosquitoes before
they're old enough to bite!
Mosquito Dunks are a form of Bacillus thuringiensis v. israelensis in a solid form. As they float in the water where you put them
they slowly release the BT on the water surface. The BT then gradually
settles to the bottom where the mosquito larva eat it and die.
Mosquito Dunks are 2 inches in diameter and 1/2 inch thick, with a small
hole in the center. The Dunks float on top of the water and will be
effective for approximately 30 days. Alternate wetting and drying will not reduce their effectiveness.
The center hole can be used to anchor the dunks in place with a string or
stake. Recommended application rates are 1/4 dunk for 1-5 square feet of
water surface area and one dunk for 25-100 square feet of water surface
area regardless of the water depth.
-
Mosquito dunks can even be used in areas that run wet
and dry, such as areas prone to periodic flooding and they still remain
effective!

1 Dunk treats 100 square feet
-
Dunks can be staked or anchored in place to keep
them from washing away. To use in moving water like a creek or slow moving
river, you can anchor the dunk with a small string and weight to keep them
in place.

BTI does not harm people, pets, birds, fish, or plants.

Mosquito Dunks can be used
in many places where we find mosquito larva. Even a tree crotch that
catches and holds water can be a breeding ground for mosquitoes! You don't
need to use the whole dunk for small places either- you can break off a
small piece as needed.
Places where dunks can be
used:
Bird Baths, flower pots, tree holes, old tires,
rain barrels, roof gutters, watering troughs, water gardens, any areas that have standing water etc.
They will not harm fish, plants or other aquatic life. They may be safely
used in animal drinking water troughs and bowls that don't have the water
changed frequently. If the water is changed every few days there is no
need for the dunks.
Caution:
Avoid
contamination of feed and foodstuffs. Do not use dunks in finished,
treated human drinking water sources.
