Quick Kill Mosquito Larvacide Dunks 6 per Pack

This is the same great biological mosquito larvae killer as QK1 in a slow release pellet. Float this in standing water for extended coverage. Completely degrades - no cleanup. Each dunk treats 100 square foot of surface water, can be broken to treat smaller areas. Unused and stored properly, dunks retain their potency indefinitely. Priced per pack.
