Mosquito Dunks contain Bacillus thuringiensis israelensis (Bti), a targeted larvicide from a naturally occurring bacterium that controls mosquito larvae. These doughnut-shaped Dunks float on water and as they dissipate into the water they will slowly release the Bti on the water's surface. Mosquito larvae growing under the water's surface will feed on the Bti and perish within 24 hours of ingestion. Under normal environmental conditions the larvae will be controlled for at least 30 days.
Mosquito Dunks can be used in all types of containerized standing water sites where mosquito larvae grow, except finished, treated drinking water intended for human consumption. This includes, but not limited to, unused swimming pools, flowerpots and saucers, bird baths, animal watering troughs, old automobile tires, ditches, ponds and rain barrels. They can also be used in outdoor areas expected to flood and indoors in places that are known to collect water, like elevator shafts, basements that flood, sump pumps and any drainage areas within buildings.
