Each dunk releases Bacillus thuringiensis israelensis (BTI), a naturally occurring bacterium that targets only mosquito larvae, providing an easy, low-maintenance approach to reducing local mosquito populations without harming people, pets, wildlife or fish.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these dunks stop mosquitoes from multiplying?\u003c\/h3\u003e\n\u003cp\u003eWhen placed in standing water, the dunk gradually releases BTI, which is ingested by mosquito larvae and disrupts their development. The active ingredient is species-specific and works on larvae stages before they become biting adults, helping to break the life cycle in treated areas.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eEach dunk treats about 100 square feet of surface water.\u003c\/li\u003e\n  \u003cli\u003eSlow-release formulation provides protection for up to 30 days.\u003c\/li\u003e\n  \u003cli\u003eTargets larvae stages only—applies before adult emergence.\u003c\/li\u003e\n  \u003cli\u003eWorks in a variety of containers: birdbaths, ponds, gutters, tires, and more.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eAre Summit Mosquito Dunks safe for pets, fish, and wildlife?\u003c\/h3\u003e\n\u003cp\u003eSummit dunks use BTI, a biological agent that is toxic to mosquito larvae but considered safe for humans, pets, livestock, birds and most aquatic animals.

Visible change to water clarity is uncommon, and routine placement won't hinder normal garden or pond use.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMinimal residue—dunks break down into biologically inactive material.\u003c\/li\u003e\n  \u003cli\u003eNo known phytotoxic effects when used according to directions.\u003c\/li\u003e\n  \u003cli\u003eSafe around ornamental plants and landscaping features.\u003c\/li\u003e\n  \u003cli\u003eRemove spent material if aesthetic concerns arise.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: Summit Mosquito Dunk Tablets are ideal for homeowners, landscapers, and property managers who want a targeted, low-effort method to control mosquito larvae in standing water.
