The rare July rain this week brought relief to a parched state, but flooded ponds and ditches will soon bring a new wave of mosquitoes.
"Now the larvae are starting to come alive again and the mosquitoes are going to start getting really overpopulated again," Curtis Benkendorfer with Georgetown Utility Systems said.
In Georgetown, they're closely monitoring for West Nile virus. So far this year, none has been found.
"If we do detect it, then we can go to Plan B which will be to spray the entire city of Georgetown," Benkendorfer said.
And you can expect, other insects to take advantage of the moisture, like fire ants.
"They build those mounds and brood their young,” Walker Hale with ABC Home and Commercial Services said. “Water is a necessary requisite."
Austinites may also see more roaches and ants around the house.
"They may have already been there, but you're now seeing the population," Hale said. "Their former habitat might be flooded out temporarily or it just gives them enough moisture that inside the house is also an OK place to live."
But Hale said that’s not all the rain stirred back to life.
"Midges, house flies, stable fly, horse fly, a lot of our beneficial flies," he said. "You get these fly explosions in a number of just a couple of days, usually from dumpsters, yard waste."
And if you think about the number of dumpsters all over the city, that's going to be billions of flies.
"Your garbage can along with just a little bit of liquid at the bottom makes a perfect habitat," Hale said.
Homeowners should also be on the lookout for termites that often swarm after a heavy rain. Many of them are beneficial agricultural termites, but it takes an expert to know for sure.
