The water's flowing and rats are going.
Just like you might want to curl up at home, area rodents are looking for a cozy new spot to settle in.
"They are pressured from the exterior,” said ABC Pest Control entomologist Walker Hale. “There's less food out there and it starts getting colder, and any time it starts getting colder you want to seek shelter. They are no different."
On top of the weather changing, Austin's rodent population has been on the move the past couple years because of construction.
"You demolish it or you build something, you disturb that habitat. When you disturb that habitat those rodents go somewhere," Hale said.
They'll take whatever home they can get.
"Rodents don't know socio-economic class,” Hale said. “Rodents can infest a $2 million home the same way they can infest a 900-square-foot home."
That's why it's important check your home yourself.
"Look in your attic,” Hale said. “Look for trails in your insulation or burrows they might be making in your insulation. Look for those little rub marks on the exterior. Look for places that are penetrations into the home."
ABC Pest Control says that blocking access is far and away the best way to stop rodents from getting in your home. That can be as simple as replacing rotted wood or putting metal grating over vents.
"If you can exclude them there, you are going to have, with a lot of confidence, a rodent-free enclosure," Hale said.
Pest control experts say there is no single area in Austin that has more rats than another. If you call an exterminator to your house, it can cost anywhere from a couple hundred dollars to a few thousand.
