## Overview

Summit Responsible Solutions Mosquito Dunks use a natural bacterium (Bti) to kill mosquito larvae in standing water for 30+ days per dunk. Covering up to 100 sq ft, these biodegradable dunks are safe for pets and wildlife, approved for organic use, and maintain potency indefinitely when dry. Ideal for rain barrels, ponds, birdbaths, and more, they provide an easy, eco-friendly solution to reduce mosquito populations and protect your outdoor spaces.

## 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.

Review: These work great, but their PACKAGING SUCKS! - These Mosquito Dunks really do the Job! We live in the desert, and have a large dry creek behind our home. It only flows occasionally, when a large rain storm passes through, a few times each year. After each flow, the creek bed dries up gradually, but leaves large pools of water, which might take a month or so to completely dry up. During that month the warm desert heat provides a PERFECT breeding place for mosquitos. Putting a few dunks in each pool solves that problem. So, why only 4 stars? That's because the PACKAGING of these dunks is virtually impossible to get into! It takes a serrated knife and a pair of scissors and a LOT of time to get these dunks out of their EXTREMELY TOUGH plastic packaging. Despite my best efforts, it takes me about an HOUR to remove all these dunks from their packaging. Hopefully, the manufacturer will read this review, and improve their packaging, so I can update this review to 5 stars, which this product would otherwise merit.
Review: Hard to remove out of packaging - I gave this a 5 star because the product does work. However, it can be difficult to get the back cardboard off - which holds each dunk in.

## Questions & Answers

**Q: I need a small amount of product for fungus gnats. 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.

### ⭐⭐⭐⭐⭐ These definitely do the job
*by A***R on 25 August 2026*

Every spring my husband puts them out. We live in the woods where there is a spring nearby that keeps the ground wet. This year we’ve had more rain than usual. They work like a charm.
