BTI Mosquito Dunks (Pack of 6 pieces)

The Easiest Way to Eliminate Mosquitoes at the Source

Tired of being bitten in your own backyard? You don't need harsh chemicals to win the battle against mosquitoes. The key is to target them before they become flying, biting adults.

BTI Mosquito Dunks are a revolutionary, biological approach to mosquito control. These small, donut-shaped briquettes are placed directly into any standing water where mosquitoes breed. As they float, they slowly release a natural bacterium that is irresistible and deadly to mosquito larvae—and harmless to everything else.

Each Dunk is the equivalent of a 30-day security system, continuously killing new generations of larvae and breaking the mosquito life cycle at its most vulnerable point.

Key Benefits at a Glance

• Breaks the Mosquito Life Cycle: Kills mosquito larvae before they can mature into biting, disease-spreading adults.
• Long-Lasting Protection: A single Dunk provides continuous, effective control for 30 days or more, even through wetting and drying cycles.
• Extensive Coverage: One Dunk effectively treats up to 100 square feet of surface water, regardless of its depth.
• Safe & Non-Toxic for Your Family & Pets: The active ingredient, BTI (Bacillus thuringiensis israelensis), is a bacterium found in soil. It is non-toxic to people, pets, fish, birds, and beneficial wildlife.
• Approved for Organic Gardening: This product is EPA-labeled for use in organic gardening, making it a trusted choice for eco-conscious homeowners.
• Proven & Trusted: The #1 best-selling home-owner mosquito control product in India.

How It Works: The Science of Simple

When placed on the water's surface, the Mosquito Dunk floats and begins its slow-release process. Mosquito larvae, which feed in the water, consume the BTI bacterium. For the larvae, BTI is highly toxic. Once ingested, it produces a protein that destroys their digestive system, killing them within hours.

Because the mode of action is so specific, other organisms—like fish, frogs, and birds—are completely unaffected. They lack the unique gut enzymes that make BTI lethal to mosquito larvae. It’s a smart, targeted solution.

Where & How to Use Mosquito Dunks

BTI Dunks are incredibly versatile and easy to use. Just apply them wherever you find standing water that you cannot drain or dump. This includes:

Application is simple:

1. Break the Dunk into pieces according to the surface area of water you need to treat (see dosage table).
2. Drop the piece(s) directly into the standing water.
3. For best results, replace every 30 days or as needed.

An Advanced Strategy: The BTI Mosquito Trap

You don't have to wait for mosquitoes to find you. Go on the offensive by creating a simple, highly effective mosquito trap to draw mosquitoes away from your patio and family:

1. The Bait: Fill a 5-gallon bucket halfway with water.
2. The Attractant: Add a handful of dead leaves, grass clippings, or straw to the water. Let it sit and "ferment" in a shady spot for 2-3 days. Mosquitoes are drawn to this scent.
3. The Kill: Drop a BTI Mosquito Dunk into the bucket.
4. The Result: Female mosquitoes will be lured to this "perfect" breeding ground. They'll lay their eggs, but when the larvae hatch, the BTI will kill them before they can grow into flying adults. You’ve just eliminated hundreds of future mosquitoes from your yard!

Comparison: Bits vs. Dunks

We often get asked about the difference between Mosquito "Bits" and Mosquito "Dunks." They contain the same active ingredient, but they are designed for different purposes.

Frequently Asked Questions (FAQ)

Q: Is BTI safe for my fish, birds, and pets?
A: Yes, absolutely. BTI is highly target-specific to mosquito and black fly larvae. It is non-toxic to fish, birds, pets, and humans, making it safe for use in koi ponds, bird baths, and animal watering troughs. It is also considered safe for beneficial insects like bees and dragonflies.

Q: Will BTI harm my dog or cat if they drink the water?
A: No. BTI is safe for mammals, including dogs and cats. It is not a poison; it's a biological control that only affects the digestive system of specific insect larvae.

Q: How long does one BTI dunk last?
A: One Dunk will provide continuous, effective control for a full 30 days, and often longer, depending on water conditions. After 30 days, simply replace it with a new Dunk for uninterrupted protection.

Q: Can I break a BTI dunk into smaller pieces?
A: Yes, the Dunks are designed to be easily broken into halves or quarters for use in smaller water sources like bird baths or plant saucers. This helps you save money and treat only the area needed.

Q: I still see mosquito larvae in the water. Is the product working?
A: Yes. This is a common and important point. The BTI Dunks do not prevent mosquitoes from laying eggs (oviposition). You will still see new larvae hatching. The Dunk works by killing these larvae after they hatch. If you see larvae that are not moving or are turning brown/black, they have ingested the BTI and will die within 24 hours.

Q: Can I use Mosquito Dunks in a swimming pool that is in use?
A: While the product is safe for humans, it is not recommended for use in pools that are being actively used for swimming. The product label states it should be used only in unused swimming pools. For in-use pools, your filtration system should prevent mosquito breeding.

Q: Is this product organic?
A: Yes, Mosquito Dunks are EPA-labeled for use in organic gardening and are approved for use by organic farmers.

Q: What is the active ingredient?
A: The active ingredient is Bacillus thuringiensis subspecies israelensis (Bti) strain BMP 144, at 10.31%.
