With warmer-than-average weather sweeping across Illinois, residents are noticing a surge in bug and insect activity. The unseasonable temperatures have created an ideal environment for these critters to thrive, leading to an unexpected influx in homes and gardens.

In Illinois, in addition, to the warmer temperatures, we've also experienced more rainfall than normal. Illinois is quickly becoming a haven for bugs and insects. The experts are calling it a 'Bug Boom'.

According to The Pest Dude, here are the insects and bugs we'll be seeing a lot more of, along with suggestions on what you might want to try to keep your home from being infested.
