## Overview

Summit 20-Pack Mosquito Dunks deliver a powerful, organic BTI formula that kills mosquito larvae for up to 30 days per dunk. Each briquet covers 100 square feet, floating and settling to treat all mosquito breeding grounds safely without harming pets, fish, or humans. Trusted by thousands, it’s the smart, eco-conscious choice for lasting mosquito control.

## 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.

Review: Reduced moskitos - Seen a reduced number of moskitos in the area since using these. I pop one in my drain ever month.
Review: Delivered efficiently, haven't tried it yet, I'll be looking out for an instruction video. Seems simple enough to use . . . for efficacy and ease of use, I will get back to you.

## 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
states the safety of the product?**

**Q: is this product pet friendly to cats and dogs... ye or no?**
A: 100% pet friendly. It's a dried bacteria and perfectly safe to eat if that's your thing. Also safe for aquatic plants and animals.

**Q: Will these harm bees and other pollinators?**
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.
