The Summit Chemical Co. 6-pack of Mosquito Dunks is an industry-standard solution for biological water treatment. These dunks are designed to float on the surface tension of the water, ensuring the treatment remains in the "feeding zone" where larvae are most active. Each dunk is rated to cover 100 square feet of surface area, providing a non-toxic alternative to chemical sprays.
Engineering & Hydrodynamic Stability
The dunks are composed of a proprietary cork-like binder that allows for a 30-day sustained release of the active biological agent. While the briquettes are engineered for stability, a practical reality is that they can arrive with cracks or some crumbling in the package. Interestingly, this increased surface area can actually accelerate the initial release of the treatment, though it may slightly reduce the total lifespan of the unit.
In non-stagnant water or areas with high wind, the lightweight design of the dunk can cause it to drift or wash away. Technical recommendations suggest using a weighted fishing line or a zip-tie through the center hole to anchor the unit. This is especially important for rain barrels and active drainage areas where the water is frequently replenished.
For treating large marshy areas where floating donuts are impractical, the 20 lb bulk Mosquito Bits allow for easy broadcast application.
This 6-pack is an essential part of any home's pest management toolkit, with more options available in our mosquito larvicide dunks collection.
