It sounds like something out of the Old Testament, or Indiana Jones' worst nightmare. Garter snakes seem to have - hopefully temporarily - taken over the town. One woman told WBBM she's seen her UPS delivery man running to avoid the snakes after delivering packages.
A snake expert told the station: "It's unusual for them to be out and that prevalent. Now, they're out feeding in larger numbers. Also the recent rains and the floods are going to drive these animals out of their [burrow]."
HLN says, "The snakes had been hibernating over the long winter, and now they are looking for food. One woman says she has seen five or six snakes hiding in the bushes." The City of Naperville Animal Control says there are 39 different species of snakes that live in Illinois, four of which are venomous.
Luckily, the garter snakes invading Naperville are a nonvenomous species.
