ST. LOUIS (KMOV.com) -- The drought is behind an increase in some critters this summer. That's because the hotter it is, the faster bugs like ticks and fleas go through their life cycles.
"Sometimes, when it's 85 degrees, it may take 10 days. When it hits 90 to 100, it may take only five days," says Gary Karr with Blue Chip Exterminators.
Karr says the bugs mature and start laying eggs at an advanced pace.
This is compounded by the fact that the St. Louis saw a mild winter and a warm spring.
"There's always a certain percentage of bugs that die off in the wintertime and because it was so mild, those that would have died off... did not," added Karr.
Other bugs are desperate for shade and moisture and they're finding shelter in homes. That's especially true of ants, says Karr.
"If you have water in your sink, they'll find a way into your house and once they find that water source, you'll wake up the next morning with a thousand ants around your sink."
When it comes to mosquitoes, the drought is helping keep those pesky bugs at bay in a lot of areas because rain water isn't pooling in spots, like ditches or yards. But, fast-moving creeks and streams have dried up and mosquitoes are thriving in the stagnant water.
