Skamania County Mosquito Control District

Scheduled Date for Adulticiding: The week of August 3, 2009

• Adulticiding is scheduled for West end of District

North Bonneville:
• Adulticiding is scheduled around the city and old town

Home Valley:
• No adulticiding is scheduled

The vast majority of adulticiding will be conducted around sunset, during nighttime hours and/or possibly early morning (around sunrise).

Adulticiding, or what is commonly referred to as fogging, is a necessary aspect of an integrated mosquito management program. Adulticiding is used to reduce mosquito populations that have matured and are capable of flight (the larger percentage of Skamania County MCD’s program is larviciding, or controlling mosquitoes while in an immature stage in stagnant waters).

While adulticiding can be an effective tool and generally provides a certain level of control in a timely manner, it is susceptible to a number of factors. Wind speed (too high), temperatures (too cold or too hot), access (being able to physically drive to areas where the mosquitoes are located) and timing (maximizing mosquito exposure while minimizing exposure to people, pets, etc) are all considerations that can affect the performance of adulticiding. Consequently, these and other factors may prevent us from performing an adulticiding event on any given date/night and in the location that we have listed.

Control efforts are often performed in non-populated areas to help reduce mosquito populations before reaching people. These sites are not updated on the website.
