Vector Control Programs
Controlling mosquito populations in the Pacific Northwest is, by necessity, a community-wide effort. The City of Beaverton and Washington County both participate in vector control programs every year to help reduce the presence of adult mosquitoes. This involves a variety of activities that include surveillance, population tracking, treatment of standing water, and, in extreme cases, treatment for the reduction of adult populations.
These activities have been shown to have a significant impact on overall mosquito populations, as well as on the subsequent potentials for human health risks. However, treatments undertaken by local governments are almost always reserved to public areas. Below is a list of ideas and resources for preventing your private property from becoming a breeding ground for these pesky (and sometimes dangerous) bloodsuckers.
The number one practice for mosquito prevention is controlling standing water. Most mosquitoes lay their eggs on, in, or around a standing water source. These eggs hatch into mosquito larvae, which spend the first part of their lives just under the surface of the water. After they pupate, they emerge as adult mosquitoes looking for a blood meal.
Common sources of standing water may include:
- Old tires
- Ponds or water features
- Untreated swimming pools
- Piled up plastic or tarps
- Any object that can hold water
Once these breeding grounds are discovered, solving the problem is often as easy as covering, moving, or re-positioning the object so as to render it less effective at catching water. In cases where this isn’t feasible, your local hardware store will likely carry a low-dose insecticide that can be added to water in some situations (For your safety, and the safety of the community, please read and follow all label directions when applying any type of pesticide).
