Mosquito Dunk Chunks are a variation of the ever-popular Mosquito Dunks and are designed to be applied to standing water. They contain Bacillus thuringiensis israelensis (Bti), a highly effective targeted larvicide from a naturally occurring bacterium. After application, the Chunks will float on the water and slowly dissipate, as they do so the Bti will be released into the water. Larvae growing in the water will then feed on the Bti and die within 24 hours of ingestion. Under normal environmental conditions the larvae will be controlled for up to 30 days.
- Bti is species-specific and will not harm beneficial insects, honeybees, tadpoles, dragonflies, or any other living creature.
- Safe to use around people, plants, pets, fish, and livestock
- Each Chunk treats up to 25 sq. ft. of surface water
- Super-easy to use - no mixing or measuring - just toss the Chunks into the water
- Mosquito Dunk Chunks should not be applied to drinking water, but it will not harm animals when added to their watering sites.
For use in standing water serving as mosquito breeding sites. This includes, but is not limited to, flowerpots and the saucers underneath them, bird baths, funeral urns, unused swimming pools, rain barrels, gutters, ditches, old tires, woodland ponds, marshes, lake perimeters, catch basins, water retention ponds, tree holes, greenhouses, cisterns, aquaponics, irrigation water, hydroponics and animal watering throughs.

Areas of Standing Water (Outside):
- In highly polluted water with a high organic content, such as sewage ponds, the application rate can be increased to as much as four times the normal dosage based after evaluating water organic content and/or seeing mosquito larvae in the water.
- When mosquito larval populations are high, aquatic vegetation dense, or the water highly polluted at the time of Chunks use, pre-treatment with Mosquitos Bits® and Dunks® is suggested.
Areas of Standing Water (Indoor Use):
For use in areas that collect water from time to time, such as elevator shafts, basements that flood, sump pump wells and any drainage areas with standing water or subject to flooding within buildings.

Chunks can be applied to sites when they are dry and in anticipation of them becoming flooded after rain.
