As temperatures cool, many homes will likely be seeing some unwanted guests inside, but there are two insects in particular that could be invading Illinois homes more than others – some in “fairly large numbers,” experts say.
While ornamental spiders are a common addition to many Halloween decorations inside and outside of the home, there may be some bugs and animals in the home uninvited this fall.
Spiders, other bugs and even a rodent or two could be found inside your home in larger numbers than usual this fall as the temperatures continue to drop.
According to Doug Taron, curator of biology and vice president of research and conservation at the Peggy Notebaert Nature Museum, if you've noticed more eight-legged creatures than normal as temperatures cool down, you're not alone -- and it might not be such a bad thing.
"Spiders are very good at keeping down other pest insects that might be in your house," Taron told NBC Chicago. "And there are all kinds of insects that that will live in people's houses. And and so spiders are actually fairly good at helping keep those numbers down. I tend to leave them unless they're too conspicuous. Like the one that was right over my dining room table."
While some of the bugs may be effective at keeping some other household pests out of the way, not all of them will serve that function, according to Taron.
Three animals, Taron says, in the form of two kinds of insects and one rodent might begin invading homes in the Chicago area this fall, some of which could arrive in "fairly large numbers": Boxelders, multi-colored lady beetles and mice.
"Mice really try to go inside at this time of year," Taron said. "This is when a lot of people will notice that they have a mouse problem as the weather is getting cooler. And they are they're seeking, you know, shelter. And and in some cases, people provide them inadvertently food, too. So there's a lot to it for a mouse to like indoors at this time of year."
As for boxelders and multi-colored lady beetles, Taron said it may all just be confusion.
"They tend to overwinter by hibernating in cracks on cliffs or under bark on trees," Taron said. "So they're like these large, fairly flat vertical surfaces. And that's what they will seek out for hibernation. And of course, the walls of houses look a lot like that."
