KILLS MOSQUITOES BEFORE THEY BECOME OLD ENOUGH TO BITE:
Kills mosquitoes for 30 days or longer when placed in standing water outdoors. Can be used in bird baths, rain barrels, old automobile tires, ponds, ditches, unused swimming pools, tree holes, flower pots, roof gutters or wherever water accumulates. The mosquito eggs are very hardy and manage to live under almost all conditions. When the water temperature is right, the eggs hatch and become mosquito larvae which swim around eating and growing. In about a week they become full-grown mosquitoes and fly out of the water looking for someone to bite. Mosquito Dunk float on water and will keep on working for 30 days or longer and are completely biodegradable. While floating, they slowly release a natural mosquito-killing biocontrol agent at the waters surface. This agent gradually settles in the water where it is eaten by mosquito larvae growing there.
