The Summit Mosquito Dunk is a specialized biological delivery system designed to manage mosquito populations at the source. The circular "donut" mold is engineered to maximize the surface area-to-volume ratio, ensuring a consistent release of the biological agent over a 30-day period. The density is calibrated so the unit remains at the water's surface, which is the primary feeding zone for larvae.
Environmental Stability & Practical Tips
The chassis is composed of a proprietary blend of compressed organic fibers. Unlike typical plastic storage, this is a consumable unit that maintains its structural integrity even during high-heat evaporation cycles. A practical reality of this design is its tendency to drift in large water features. Using the center aperture to tether the unit with a zip-tie or weighted fishing line prevents it from washing away during heavy rainfall or pooling in corners where it might be less effective.
Tests indicate that the dunks are effective in water temperatures up to 40°C, making them suitable for various climates. Because they are biological, they are non-toxic to mammals and fish, focusing solely on the target fly larvae. There is no risk of synthetic chemical buildup in your garden soil or water features.
One dunk provides coverage for 100 square feet of surface area, and the biological spores remain dormant until hydrated.
For treating wider areas of standing water where dunks might be difficult to place, the 30oz Mosquito Bits provide a broadcastable alternative.
