The 6-pack of Summit Mosquito Dunks uses a slow-release "floating" substrate to target mosquito larvae in their primary feeding zone. This biological solution is designed for sustained aquatic management without the need for mechanical traps or electrical components. The "donut" shape is a functional design choice that provides a high surface-area-to-volume ratio for consistent dissipation of the active ingredient.
Performance & Practical Reality
Technical analysis indicates that the 30-day slow-release claim is most accurate in stagnant ponds. In high-flow drainage areas, the material can erode up to 40% faster than the specified rate. The rings are somewhat brittle, and it is a practical reality that some fragments may be present in the packaging; however, these fragments remain active even if the circular shape is lost.
Since the product is lightweight and designed to float, it can be prone to drifting or washing away during heavy rainfall. Using a fishing line or zip-tie through the center hole allows you to anchor the unit to a fixed point, ensuring it remains in the target area throughout its 30-day lifespan. This method is particularly useful for rain barrels and gutters.
- Targets only mosquito, blackfly, and fungus gnat larvae.
- Maintains buoyancy for up to a month, even as the mass degrades.
- Safe for use in water features containing fish or visited by pets.
If you prefer a granular format for broadcasting over a wider, marshy area, the 8-ounce Mosquito Bits offer a faster release on a corn-cob carrier.
This product is a core component of biological water treatment, and further options can be explored in our mosquito larvicide dunks section.
