Summit Mosquito Dunks: Biological Mosquito Control.

Kill Mosquitoes Before They Can Bite: #1 EPA-Approved Organic Standing Water Treatment.

Stop mosquito infestations at the source before they ever reach your yard. Summit Mosquito Dunks are America’s #1 trusted home mosquito control solution, engineered to target and destroy mosquito larvae before they mature into biting adults. Powered by BTI—a naturally occurring bacterium that is toxic only to mosquito larvae—each Dunk provides 30 days of continuous protection across 100 square feet of standing water while remaining completely safe for fish, pets, birds, wildlife, and humans.

Key Highlights ;

• Kills Mosquito Larvae at the Source: Destroys larvae within hours, breaking the mosquito breeding cycle before they can fly or bite.

• Powered by Natural BTI: Contains Bacillus thuringiensis israelensis, a natural biological larvicide that targets only mosquitoes, black flies, and fungus gnats.

• 30-Day Long-Lasting Protection: Floating sustained-release ring continuously treats up to 100 sq. ft. of surface water for a full month.

• 100% Safe for Wildlife, Pets & Fish: Non-toxic to dogs, cats, birds, fish, frogs, honeybees, and beneficial garden insects.

• EPA Organic Gardening Labeled: Approved for organic use in vegetable gardens, rain barrels, and eco-friendly outdoor water features.

• Versatile Water Placement: Perfect for birdbaths, rain barrels, ponds, garden fountains, planter reservoirs, gutters, and animal troughs.

Why Mosquito Dunks Outperform Chemical Sprays? 

• Targeted Breeding Prevention (Proactive Defense).

  Sprays only kill adult mosquitoes on contact, leaving thousands of eggs behind. Dunks neutralize the source in standing water so you don't have to spend your summer spraying harsh chemical fogs.

• Ecosystem & Pet Safe (Peace of Mind).

  Keep your family, pets, and local wildlife completely safe. BTI specifically attacks the digestive system of mosquito larvae without harming pond fish, drinking pets, pollinating bees, or wild birds.

• Set-It-and-Forget-It Convenience (Effortless Protection).

  No complicated mixing or spraying required. Simply toss a Dunk into any standing water source and let it float—it automatically releases continuous biological control for 30+ days.

How to Use for Best Results?

1. Identify areas of standing water around your home or garden (birdbaths, rain barrels, ponds, gutters, or drainage ditches).

2. Drop 1 full Mosquito Dunk per 100 square feet of water surface area (can be broken into smaller pieces for smaller areas like birdbaths).

3. The Dunk will float on top of the water and slowly release BTI for 30 days. Replace monthly throughout the mosquito season.
