Summit Mosquito Dunks Organic

Summit Mosquito Dunks Organic is a microbial larvicide dunk for standing-water mosquito larvae control, a biological mosquito control option for ponds and water-holding containers.

Each dunk is a biodegradable, donut-shaped floating briquet designed to sit on standing water and release a long-term biological mosquito larvicide over time. The result is targeted, sustained-release mosquito control that focuses on the larval stage, helping reduce emerging adult mosquitoes from the water sources around homes, gardens, farms, and outdoor living spaces.

The active ingredient is Bacillus thuringiensis subspecies israelensis (Bti), a naturally occurring bacterium used as a Bti larvicide for mosquito larvae. In simple terms, it’s a bacterial active ingredient that is toxic to mosquito larvae and is described as harmless to other living things. Summit Mosquito Dunks are also suited to organic production, making them a practical fit for growers and homeowners who want an organic-friendly mosquito larvae control approach without harsh, broad-spectrum chemistry.

Summit Mosquito Dunks are designed for use anywhere water collects and remains for periods of time, including rain barrels, birdbaths, koi ponds, animal watering troughs, planter reservoirs, tree holes, rain gutters, and similar standing-water sites. They are also described as appropriate for areas where animals and pets drink or bathe, and as having no effect on plants, fish, frogs, turtles, or beneficial insects. Because this is mosquito larvae control, it is specifically aimed at the aquatic larval stage rather than adult mosquitoes.

This is a good fit for anyone looking for a standing water mosquito control product that combines a sustained-release microbial larvicide, a biodegradable floating dunk format, and a Bti larvicide active designed to target mosquito larvae in common water-collection hotspots.
