Mosquito population on the rise in Madison

Posted: Updated:

MADISON (WKOW) -- If you think the mosquitoes have gotten worse around town over the past few days, you thought right. You can feel them just about anywhere you go. But what's causing the influx in their population?

Bug experts say a big part of it is the large amount of rain followed by high temperatures.

"They are waiting for the heavy rains to come. We get these temporary pools and puddles out in the woods that might only be around for a week or two weeks or three weeks -- they lay eggs in those situations," said P.J. Liesch, an entomologist at UW-Madison.

He says those eggs can hatch between 10 and 14 days later depending on how hot it gets. With Thursday's showers, that means we could be in for another generation of mosquitoes that are currently incubating. 

"It wouldn't surprise me if we continued to see high mosquito numbers going through the month of august and especially if the rains continue," Liesch projected. 

Several local pesticide companies say business is up. But Liesch warns, spraying your yard night not be a lasting fix.

"If you fog in your yard, it's going to kill the mosquitoes that are flying around at that time, but then those little droplets disperse. It stops working fairly quickly," he added.

However, there is some good news for Madisonians -- we shouldn't have to worry about viruses like Zika and West Nile.

"There are two very specific species of mosquitoes that are believed to vector Zika virus, we don't have either of those species up here," Liesch reassured. 

The only Zika cases in the state involve people who contracted it while traveling down south. 

As far as relief goes, we shouldn't see a drop in the annoying insect's population for quite some time. It might not be until we have our first couple frosts later this year, according to Liesch.
