Measures to Reduce Mosquitoes (Larva Control)
Reduction of the mosquito population can be done with minimal use of pesticides. Targeted use of larvicide, Bacillus Sphaericus (BS), will be placed in all catch basins in Norwalk. Bacillus Thuringiensis Isrealensis (BTI) will be used in stagnant bodies of water, floodwater sites, roadside ditches, freshwater marshes, and wetland areas to help reduce the mosquito population.

Reducing Mosquitoes Around the Home
  • Change water in bird baths on a weekly basis
  • Clean and chlorinate swimming pools and, when not in use, use pool covers
  • Clean clogged roof gutters
  • Dispose of water-holding containers, such as ceramic pots, used tires, tire swings
  • Drill holes in the bottom of containers such as those used for recycling
  • Turn over objects that may trap water when not in use such as wading pools and wheelbarrows
  • Use landscaping techniques to eliminate areas where water can collect on your property
