Mosquito Dunks provide effective mosquito control for standing bodies of water and kill mosquitoes for 30 days or longer under normal environmental conditions. Each dunk is inoculated with a beneficial bacteria (Bacillus thuringiensis israelensis) that releases into the water once placed. This bacteria is a microbial insecticide that prevents mosquito larvae from feeding once ingested. Mosquito Dunks are perfect for mosquito control in containerized standing water areas: flower pots, tree wells/holes, bird baths, roof gutters, rain barrels, animal water troughs and more.

Dunks will float in water and can be anchored with string to prevent them from being washed away. Mosquito Bits are suitable alternatives to the Mosquito Dunks when bodies of standing water are not present. Alternate drying and wetting does not reduce the effectiveness of Mosquito Dunks or Mosquito Bits.

Application Rates: The square footage below refers to surface area of the standing water.

  • 1-5 Square Feet – ¼ dunk
  • 5-25 Square Feet – ½ dunk
  • 25-100 Square Feet – 1 dunk
  • 100+ Square Feet – 1 dunk per 100 square feet.
Mosquito Dunks also can be used as a pre-flood treatment in areas expected to become breeding sources.
