How Do Mosquito Dunks Work?

Mosquito Dunks work by using a natural bacterium called BTI to kill mosquito larvae in standing water before they turn into biting adults. When you place a dunk in water, it slowly releases BTI, which is harmless to people, pets, and wildlife but deadly to mosquito larvae. It’s an easy, low-maintenance way to break the mosquito life cycle and keep your outdoor spaces more comfortable all season long.

What Are Mosquito Dunks?

Mosquito Dunks are a larvicide product made to prevent mosquitoes from developing in areas with standing water. Shaped like small, floating rings, they release a natural bacterium called Bacillus thuringiensis israelensis (BTI) that specifically targets and kills mosquito larvae. Safe for use around people, pets, and wildlife, Mosquito Dunks are a popular, eco-friendly option for treating ponds, birdbaths, rain barrels, and other water sources where mosquitoes like to breed.

How Do Mosquito Dunks Work?

Mosquito Dunks work by breaking the mosquito life cycle before it reaches the biting stage. Once placed in standing water, the dunk slowly releases BTI, a natural larvicide that targets mosquito larvae. Here's a quick look at the process:

  1. Drop the dunk into standing water where mosquitoes may be breeding.
  2. The dunk dissolves gradually, releasing BTI over time.
  3. Mosquito larvae ingest the BTI as they feed in the water.
  4. The BTI kills the larvae by disrupting their ability to digest food.
  5. One dunk protects the water for up to 30 days, even through multiple hatches.

How Long Does it Take Mosquito Dunks to Work?

Mosquito Dunks start working within just a few hours of being placed in water, and you can expect to see a noticeable reduction in mosquito larvae within about 24 to 48 hours. The active ingredient, BTI, begins affecting larvae as soon as they ingest it, making the dunks a fast-acting solution for interrupting the mosquito life cycle.

Are Mosquitoes Attracted to Mosquito Dunks?

No, mosquitoes are not attracted to Mosquito Dunks. These products don’t lure mosquitoes—they simply work in water where mosquito larvae are already present. The dunk releases BTI into the water, which kills the larvae when they feed, but it doesn’t draw adult mosquitoes in or encourage them to lay eggs.

Do Mosquito Dunks Only Kill Larvae?

Yes, Mosquito Dunks are specifically designed to kill mosquito larvae. Dunks do not harm adult mosquitoes, nor do they prevent mosquitoes from laying eggs, so they should be used alongside other methods for comprehensive mosquito control.

Are Mosquito Dunks Safe to Use Indoors?

Yes, Mosquito Dunks are safe to use indoors as long as they’re placed in standing water that isn’t used for drinking. You can use them in places like plant saucers, decorative water features, or unused drains. The active ingredient, BTI, is non-toxic to people, pets, and wildlife, making it a safe option for indoor mosquito control when used as directed.

Can You Reuse Mosquito Dunks?

No, Mosquito Dunks cannot be reused. Once the dunk has dissolved and released its active ingredient, it loses its effectiveness. Each dunk typically lasts for about 30 days, after which it needs to be replaced to continue controlling mosquito larvae. Be sure to check and replace the dunks regularly during the mosquito season for ongoing protection.
