Routine Performance

Crews perform daily surveillance in which they search for potential mosquito breeding. They also pay close attention to changes in weather temperature and conditions. Keeping track of the amount of rain fall helps to predict the likelihood of mosquito emergence. This information helps mosquito control stay on the offensive in preventing production of adult mosquitoes in the city.

Dippers are used to inspect for juvenile mosquitoes such as larvae and pupae. Dipping is an important part of surveillance to help identify areas of breeding.

  1. Crew leader inspecting ditches to check for possible breeding.
  2. Even catch basins can breed mosquitoes when they hold water. Inspecting all possible areas for breeding is critical in controlling populations.
  3. Rain gauge used to measure weekly rain fall. One inch of rain in a week = mosquitoes the next week
  4. It's the little spots of water that contribute the most problems in Mosquito Control. It's easy to blame it on a lake or large ditch, but the small, hidden areas are just as important. Always be vigilant and remove any source of standing water.

Juvenile Mosquitoes

Juvenile mosquitoes are collected from various water sources such as:
  • Artificial Containers
  • Ditches
  • Natural Bodies of Water
  • Puddles
  • Retention Pools

Next Steps

When mosquito breeding areas are identified, treating is our next step as part of our "seek and treat" motto. Staying proactive and using preventive measures is the most effective and cheapest way to control mosquitoes.
