Product Information

Mosquito Dunks Kill Mosquito Larvae (Before they can bite)

Mosquito Dunks attack mosquitoes at the larvae stage, before they become biting adults. 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 and start biting.

How Mosquito Dunks Work

Mosquito Dunks containing Bt israeliensis float on water and will keep on working for 30 days or longer. Mosquito Dunks are completely biodegradable. While floating, they slowly release a natural mosquito-killing biocontrol agent, Bti (Bacillus thuringienis israelensis) at the water's surface. This agent gradually settles in the water where it is eaten by mosquito larvae growing there. Bti (Bacillus thuringienis israelensis) is a bacterial toxin that infects and kills mosquito and black fly larvae. It is safe and environmentally sound because it is highly selective, killing mosquitoes and black flies.

Are Mosquito Dunks Safe ?

Bti contains no poisonous chemicals and is completely harmless to other living things! When Bti is eaten by the mosquito larvae, it damages the gut cells, eventually entering the body cavity. Once this happens, the larvae die.
