Mosquito Dunks (Bti Briquets) 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.

Directions of Use:

• 1/4 dunk for 1-5 sq feet of standing water.
• 1/2 dunk for 5-25 sq feet of standing water.
• 1 dunk for 25-100 sq feet of standing water.
• Tie dunk to an anchor if dunk can be washed away.
• Check on the dunk after 30 days and replenish if needed.
