Mosquito Dunks
Mosquito Dunks
- Easy-to-use biological mosquito control for ponds and water gardens
- Controls mosquitoes, potential vectors of West Nile Virus, for 30 days
- EPA-registered mosquito control in all 50 states
Biological mosquito control prevents your water garden from becoming a mosquito breeding ground. Used by professionals for more than a decade to effectively kill mosquito larvae before they mature into biting adult pests. Slowly released Bacillus thuringiensis israelensis (Bti), a biological mosquito larvicide, works for 30 days or more. Works fast on mosquito populations (within 24 hours) to treat up to 100 square feet of surface water, regardless of depth. 2" diameter dunks can be easily broken up to treat small areas. Unused Dunks retain their potency indefinitely, so you can store them without waste.
Recommended usage: Place one Mosquito Dunk in pond for every 100 square feet of water surface, every 30 days.
Outdoor Use Around the Household
Use one (1) Mosquito Dunk for up to 100 square feet of water surface,
regardless of depth. Use whole or broken into portions and applied to
containerized standing water near the home.
