What is a Mosquito Dunk?
Made with Bt-israelensis (Bt-i), a highly specific biological pesticide, this product represents a major breakthrough for people and the environment when compared with the traditional toxic chemical approach to mosquito control. Mosquito Dunks will NOT harm people, pets, wildlife or fish.

Once a month place wherever water accumulates around your home. Each Dunk will effectively treat up to 100 square feet of surface water regardless of depth. They may also be broken in half to treat smaller areas. Great for use in water gardens, flower pots, bird baths, rain gutters and decorative ponds!

Mosquito Prevention Measures
PREVENT SOURCE BREEDING (MOST EFFECTIVE) – Dump stagnant water from gutters, old tires, pots, and small containers. Cover rain barrels and change bird bath water daily. A 3” potted plant tray can produce hundreds of larvae.

AVOID MOSQUITOES AT FEEDING TIME (EFFECTIVE) – Try not to be outside late in the evening (dusk) when female mosquitoes are searching for a blood meal. The majority of attacks occur at this time. If you must go out, wear repellant containing DEET and long sleeves and pants. Make sure screens and exterior doors are closed and in good repair.
