Bti, a bacterium toxic only to mosquito larvae, stops mosquitoes before they are old enough to bite, and it is non-toxic to birds, pets, and fish. Mosquito Dunks, 20-Pack puts that Bti into 20 dunks, each treating 100 square feet of surface water for 30 days or more.
How Long Does One Dunk Last, and How Much Water Does It Treat?
One dunk treats 100 square feet of surface water and lasts 30 days or more. A dunk can be broken into smaller pieces when less water coverage is needed, which makes a 20-pack go further on small water sources.
What Safety Approvals Cover Use Around Birds, Pets, and Fish?
Bti is non-toxic to humans, pets, birds, fish, and most other non-target organisms. The EPA has registered the dunks for use in animal watering troughs and fish habitats, and they are approved for organic production and gardening under the National Organic Program guidelines.
Which Standing Water Spots Can Be Treated?
The dunks work in any standing water or water garden, including birdbaths, rain barrels, water troughs, koi ponds, flower pots, and gutters. That covers most places where water collects and remains for periods of time.
Who These Mosquito Dunks Are For
- Birders who want to treat a birdbath without harming the birds that use it
- Gardeners with rain barrels, water gardens, or koi ponds
- Pet and livestock owners with animal watering troughs
- Gift buyers looking for a practical, long-lasting gift for a gardener or homeowner
Frequently Asked Questions
Which Mosquito Species Do the Dunks Work On?
There are approximately 2,500 species of mosquitoes throughout the world, and the Bti in the dunks kills the larvae of all of them.

What Happens if a Dog Eats a Dunk?
According to the product page, even if a dog eats an entire dunk, it will not adversely affect the animal.
