## Overview

Summit 20-Pack Mosquito Dunks use Bacillus thuringiensis israelensis (BTI), a bacteria toxic only to mosquito larvae, providing up to 30 days of organic, eco-friendly mosquito control. Each dunk covers 100 square feet, floating and settling to release active ingredients evenly in various breeding sites without harming pets, wildlife, or humans.

## Description

The briquets/dunks are formulated to release effective levels of Bti for a period of 30 days or more under typical environmental conditions. The floating action of the briquets/dunks will ensure that active material is released at the surface as well as gradually settle to the bottom. These briquets/dunks may be used in all types of mosquito breeding areas. To prevent briquets/dunks from being flushed out of certain treatment sites, they can be anchored using string tied through the hole in the center or staked in place. They can also be used for preflood treatment. If the briquets/dunks are applied to dry areas which are known or suspected to become breeding sites when flooded, such as woodland pools and abandoned swimming pools, the briquets will float to the surface when flooding occurs and start releasing the active Bti material. Alternate wetting and drying will not reduce their effectiveness.

## Questions & Answers

**Q: how many gallon/ton water does one dunk covers for pond?**
A: I realize this is an old question but for people wondering, we have an 86' diameter pond. To find out how many dunks are needed we half the diameter to the radius (43), square that number by multiplying it by itself (43x43=1849) then multiply by 3.14159 (5808.8) now divide by the 100 Sq Ft each dunk covers = 58 dunks to do our pond for 30 days. Wow. The better solution for a large pond is a submersible sump pump on a timer to come on at regular intervals and keep the water aerated and moving.

**Q: What is the exact definition regarding cats and dogs safety?   What agency

A: No it will not harm bees or other pollinators.  This is not a chemical insecticide.  It's a bacteria that attacks only mosquito larvae in stagnant water.

### ⭐⭐⭐⭐⭐ Review
*by E***E on 15 April 2026*

Before getting into the nitty gritty of my review it’s worth noting that I live in eastern NC and the mosquitos are insane compared to what I am used to when I lived in south New Jersey. My youngest child has skeeter syndrome. I started using these around mid-April of 2025 and the difference in our yard has honestly been massive. We went from getting eaten alive by mosquitoes to being able to stay outside in the evenings without being eaten alive by the bugs. My kids are out there for hours, sometimes until after 8pm, and we’re usually coming inside because it’s bedtime, not because of mosquitoes. One of my kids is very sensitive to mosquito bites, so finding something that actually helps without spraying the whole yard has been a big deal for us. I use them by breaking a dunk into 4 pieces and placing them in buckets of standing water around the yard (sometimes called “doom buckets”). The idea is that mosquitoes lay eggs in the water, and when the larvae hatch, they eat the BTI in the dunk and die. It works quietly in the background without much effort once it’s set up. I noticed a change in the mosquito population in my yard within 10 days. We had no new mosquito bites by week 3. I also like that it’s safe to use around kids, pets, and wildlife, which was important to me. I just refresh them about once a month and don’t have to think about it much in between. I have a calendar event in my phone that goes off every 25 days to remind me to toss in a new dunk piece. It’s not going to make your yard 100% mosquito-free, but it has made a very noticeable difference for us and made being outside much more enjoyable. Pros: Noticeably reduces mosquitoes Easy to use Low maintenance Safe to use around kids and pets Insanely cheap compared to yard sprays that don’t work Cons: Have to consistently use if you actually want to control mosquitos If humidity is high (like within 24 hours of rain) mosquitos will still be hanging out around your property. You need to keep leaf litter cleaned up as mosquitos are attracted to the smell of decaying leaves.
