Is there a way to let you know that mosquitoes are bad in my area?

If you have noticed an increase in the mosquito population in your area, you can submit a Vector Control Service Request. Service Requests help us to find unknown mosquito development sites and pinpoint problematic areas.

How can I help to reduce the mosquito population in my own yard?

One of the most effective things you can do is to remove any standing water you may have on your property. This can be flower pots that hold water, baby pools, or old tires you have laying around. Source reduction is the best way to combat mosquitoes!

How do you keep track of the mosquito population?

We operate a variety of mosquito traps that are dispersed throughout the county and its municipalities. We collect these traps on a daily basis, excluding weekends and holidays. Traps are counted and the numbers of individual species are recorded. Pools of mosquitoes are then tested for the presence of harmful diseases like West Nile virus....

Mosquitoes are so bad this year! Why?

There is a very direct relationship between the amount of standing water the number of mosquitoes we have during the year. The more rainfall and flooding the more likely it will be a bad year. There are exceptions, but they are not very common.

Why doesn’t the Air Force Reserve spray every year?

Vector control treatments conducted by the U.S. Air Force Reserve (USAFR) are only a request. The USAFR has the ability cancel or change their plans with little prior notice. Spray requests are scheduled 2 years in advance. This makes targeting their arrival date very difficult. Some years all the pieces come together and others it...

I never see Vector Control out and about. Are you even treating this year?

Adulticide treatments occur near sunset when mosquitoes are most active and sprays can be the most effective. In the summertime that can mean 10 pm or later. Depending on the application method you may or may not even hear or see the vehicle. Aerial applications are conducted with either a helicopter (rural areas) or airplane...
