Biological Mosquito Control is now approved for use in Canada. Safe for fish! Use in rain barrels, roof gutters, bird baths, flower pots...wherever standing water could become a breeding ground. Toss in a puck for every 100 square feet of surface area and you have 30 days of treatment!

Microbial larvicides are bacteria that are registered as pesticides for control of mosquito larvae in outdoor areas such as irrigation ditches, flood water, standing ponds, woodland pools, pastures, tidal water, fresh or saltwater marshes, and storm water retention areas. Duration of effectiveness depends primarily on the mosquito species, the environmental conditions, the formulation of the product, and water quality.

Keep mosquitos from breeding in standing water simply drop the floating tablet into the water, and as it slowly dissolves, it releases a bacterium that is toxic to all species of mosquito larvae—and harmless to other living things, making it the perfect solution. This larvicide gradually settles and travels through the water, and as female mosquitos lay their eggs in standing water, the larvae will hatch and begin to eat the bacterium. This kills the larvae before they can grow up and become biting and disease-spreading adults.
