Mosquito Dunks are used to control mosquitoes in their early stages of life. The larvae are killed while still in the aquatic stage of their life cycle. To control them at this stage, just toss in one Mosquito Dunk per 100 square feet of water surface area. This protection will last up to 30 days.
You can add Mosquito Dunks to the water in ditches, ponds and rain barrels . The Mosquito Dunks are not harmful to people, pets, wildlife or fish. Mosquito Dunks start to work within hours of application.
Note: It is also important when trying to control mosquitoes that you empty out old buckets and tires of standing water. Bird baths and fountains that are not chlorinated should also have a complete water change every few days to avoid the emergence of mosquitoes.
