The Summit #111-5 20-count package is designed for homeowners who require consistent, season-long management of stagnant water. This biological control system uses a proprietary cork-based floatation matrix to keep the active ingredients at the water's surface. One dunk is rated to cover 100 square feet of surface water, regardless of the depth, making it a scalable solution for both shallow saucers and deeper rain barrels.
Functionality & Practical Realities
Unlike rapid-release liquids, this solid-state delivery system provides a sustained release cycle through gradual surface erosion. This mechanical degradation is designed to last for 30 days. It is important to note that this product is a preventative tool; it does not eliminate adult mosquitoes but helps manage the population at the larval stage before they become flying pests. A 48-to-72-hour window is typically required to see a reduction in larval activity.
The frame of the dunk is sturdy enough for daily outdoor use, but it can get trapped in leaves or floating debris, which may reduce the effective release area. If the water level in your container fluctuates or overflows frequently, tethering the dunk to a fixed point is recommended to prevent the unit from being lost during heavy rain events.
For immediate treatment of active infestations in soil or smaller containers, the Summit Mosquito Bits offer a faster-release corn-cob carrier.
These biological dunks are essential tools for maintaining a comfortable outdoor space, and you can explore more options in the mosquito larvicide dunks collection.
