Used by professonals for more than a decade, Mosquito DunksŪ have proven their value in destroying Mosquitos - by killing the larvae before they mature into biting adult pests. Mosquito Dunks' Bacillus Thuringeniensis Israeliensis, (Bt israeliensis or b.t.i.), is the most convenient sustained release mosquito larvaecide available.
Made with natural B.t.i., Mosquito Dunks represent a major breakthrough for people and the environment when compared with the traditional toxic chemical approach for mosquito control.
Once a month float a Dunk in the Water Garden and every place water accumulates around your home - you'll be rid of mosquitos for the whole season. Each Dunk will effectively treat up to 100 square feet of surface water regardless of depth. Dunks may be broken to treat small areas.
This biological pest control kills mosquito larvae but is completely non-toxic to animals such as fish, birds, wildlife, and pets. B.t.i. Mosquito Dunks are safe to use in pet watering bowls, horse troughs, lakes, bird baths, fish ponds, flower pots, aquatic gardens, flood control basins, unused swimming pools and other areas where standing water is a possible breeding ground for mosquitos.
Unused and dried out Dunks retain thier potency indefinitely.
