Dry Summer Keeps Mosquitoes Away

Mosquitoes Tested For West Nile VirusCENTRAL POINT, Ore. — Jackson County Vector Control reports a historically quiet summer. They say it’s in part due to a dry summer.

There aren’t as many backyard mosquito problems because rain isn’t filling wheelbarrows or empty containers often found near homes. So, fewer calls are coming in for vector control service.

On a normal year, records show an average amount of calls at 2,250 by this time in the summer, and only 1,715 people needed service this year. Biologists say the low moisture levels help in problem species like the tree hole mosquito.

“Their actual larval habitat is in the cavities of trees that fill full of water well years where there’s little rain there’s less of those cavities filling with water so the larval production is a lot lower,” said Jim Lunders with Jackson County Vector Control.

The drought conditions also work against Vector Control by limiting the amount of water sources. If there are fewer places for birds and mosquitoes to get water, they often end up in close proximity, increasing the likelihood of the spread of West Nile.
