If You Live in These States, Prepare for More of This Deadly Spider, Experts Say

Arachnophobes beware: these spiders could be making their way to an area near you.

There are tons of things to love about summer, from spending time at the beach with family and friends to barbecuing in the backyard. Unfortunately, with the warm weather tends to come an uptick in outdoor pests, from garter snakes in your garden to cicadas in your back yard.


And while the vast majority of the insects, reptiles, and other small creatures you encounter during the summer are relatively innocuous, there’s one notable exception to this rule: the brown recluse spider. The venomous arachnids, whose bites can cause tissue necrosis—and, in extremely rare cases, can be fatal, particularly among children—have been particularly active in two states this summer due to high heat conditions.

The spiders are now a common sight in both Illinois and Missouri, Jay Everitt of Rottler Pest Solutions explained to KMOV.com.

“They like these quiet spots of our homes. The closets, the basements, the attic areas," Everitt explained. However, when temperatures exceed a certain point and attic temperatures get too hot, “[The spiders] start seeking cooler environment and a lot of time that's the living space."

However, Illinois and Missouri are far from the only states where you can find this venomous arachnid. According to research published in the Journal of Medical Entomology (JME), the spider is readily found throughout the U.S.* Read on to discover if this venomous spider calls your state home.

*Delaware was not represented in the study data.
