Each biodegradable dunk treats up to 100 square feet of water, is safe for pets and wildlife, and is approved for organic use. Ideal for rain barrels, birdbaths, and other water-holding spots, these dunks offer a hassle-free, eco-conscious solution to mosquito control with indefinite shelf life when dry. ## Description A Mosquito Dunk looks like a small, beige donut which floats on standing water. As the Dunk slowly dissolves, it releases a bacterium which is toxic to all species of mosquito larvae. The active ingredient in Mosquito Dunks is Bacillus thuringiensis subspecies israelensis (Bti). Bti is a bacterium that is deadly to mosquito larvae but harmless to other living things. Just float a biodegradable Mosquito Dunk in water troughs, koi ponds, birdbaths, rain barrels, animal watering troughs, elevator shafts, or any place where water collects and remains for periods of time. While floating, a Mosquito Dunk slowly releases a long-term biological mosquito larvicide at the water's surface. This larvicide gradually settles in the water, and while it travels through the water it is eaten by the mosquito larvae growing there. When female mosquitoes lay their eggs in standing water treated with a Mosquito Dunk, the larvae will hatch and begin to eat the Bti. The Bti will kill the mosquito larvae before they can grow up to become biting and disease-spreading adults. Each Mosquito Dunk will effectively treat 100 square feet of surface water for 30 days or more. For less water, a portion of a Mosquito Dunk can be used. Homeowners, ranchers and farmers looking for a safe, nontoxic way to control mosquitoes can use Mosquito Dunks, which kill mosquitoes before they can become flying, biting, disease-carrying adults.

Can I mix a batch with one dunk and store it to spray onto the surface of my garden as needed?** A: Hi I just saw your question, and i have a way these work for my plants. I use gallon milk jugs and put 1/4 of a mosquito dunk in each. For a small sprayer you'd only needed a small piece, but just spraying your plants or the top of the soil won't kill the larvae. You'll need to water each plant with the treated water to effectively eradicate the gnats. I've found that the small piece that I use lasts for a month, and i just write the date on a piece of masking tape attached it to the jug. I'm not 100% sure, but with these being made up of live bacteria, I don't cap the jugs. Idk if they require air, but I don't want to mistakenly kill those. I hope this helps! **Q: Where can I place these if i have no standing water in my backyard or front yard and how many for a total 1/4 acre?** A: Why would you want to use these if you have no standing water? That’s all they’re designed for. Perhaps the mosquitos you’re fighting are coming from a neighbor’s yard who does have standing water, in which case they’re the ones who should be using this product. **Q: I use these in buckets or kid water table. Should the standing water be replaced periodically? If so, how often. Do the dunks need to be replaced too?** A: Dont use this in your kids water. Just fill up the water table fresh and dump it out every time theyre finished playing. **Q: Picture shows one pack of 20 dunks, but title says 100 ct. Nowhere in the description does it say 5 packs of 20. How many dunks total??** A: I too found that a little confusing, but yes 100 dunks. ## Customer Reviews ### ⭐⭐⭐⭐⭐ This stuff works!! *by H***U on 19 January 2023* ### ⭐⭐⭐⭐⭐ Great Way to Get Rid of the Mosquitoes *by L***C on 21 September 2023* ### ⭐⭐⭐⭐ Get this ... it works & is safe *by L***E on 26 June 2025* ## Frequently Bought Together - Summit…responsible solutions 155 Summit 100 Count Mosquito Dunk, Natural - SUMMIT CHEMICAL CO 117-6 30OZ Mosquito Bits - Spartan Mosquito Pro Tech - 1 Acre Pack 4 Tubes (2 Boxes) 100% American Made --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.uy/products/621623688-responsible-solutions-155-summit-100-count-mosquito-dunk-natural](https://www.desertcart.uy/products/621623688-responsible-solutions-155-summit-100-count-mosquito-dunk-natural) --- *Product available on Desertcart Uruguay* *Store origin: UY* *Last updated: 2026-04-22*
