Summit Chemical 102-12 Mosquito Dunks Tablet 2-pack

Product Description

The SUMMIT CHEMICAL 102-12 Mosquito Dunks are a biological mosquito control tablet designed for use in standing water environments. Each dunk releases Bacillus thuringiensis israelensis (Bti), a naturally occurring soil bacterium that targets and kills mosquito larvae before they reach the adult biting stage. The active ingredient is selectively toxic to mosquito larvae and does not harm fish, wildlife, pets, or beneficial insects. A single dunk treats standing water for 30 days or more, making it an efficient option for ongoing larval control without repeat daily application.

These dunks are suited for use in water gardens, ornamental ponds, bird baths, rain barrels, tree holes, flower pots, and any other area where standing water accumulates and mosquitoes breed. Pool service professionals and pest control technicians use them in low-flow or non-circulating water features where chemical larvicides may not be appropriate. The ready-to-use tablet format requires no mixing or measuring — simply place the dunk in the target water source.

Installation Notes

No professional license is required for consumer use, though pest control technicians should follow applicable state regulations when applying biological larvicides on a commercial basis. Place the dunk directly on the water surface — no tools required. Remove and replace each dunk after 30 days or when it has fully dissolved to maintain continuous larval control. Keep product stored in a cool, dry location away from direct sunlight when not in use.
