Mosquito Dunks

Used by professionals for more than a decade, Mosquito Dunks® have proven their value in destroying mosquitoes by killing the larvae before they mature into biting adult pests. Mosquito Dunks float on water and will keep on working for 30 days or longer. While floating, they slowly release a natural mosquito-killing biocontrol agent, Bti (Bacillus thuringiensis israelensis), at the water's surface.
