5 insights about snakes, bugs and arachnids that could end up in your Illinois home

This winter, Illinois households may encounter common pests like snakes, bugs, and arachnids seeking shelter in warmer environments. Snakes, including non-venomous varieties such as the eastern garter snake and the western rat snake, may become more visible in home gardens and yards. They play ecological roles by controlling rodent populations but can inadvertently find their way indoors. Meanwhile, arachnids like wolf spiders frequently slip into basements, sheds, and other crevices; however, they usually pose no threat to humans and help manage insect populations.

Homeowners are advised to seal entry points to prevent these pests and maintain awareness of signs of activity, such as droppings or sightings. As cooler temperatures prompt pest movement indoors, vigilance and preventive measures remain key in managing potential home intrusions throughout the season.
