Pest control guides for Illinois homeowners

Practical, Illinois-specific advice: what to prevent, how to spot a problem early, and when it is time to bring in a licensed exterminator.

These guides are written for Illinois conditions: the housing stock, the climate, and the pest calendar that runs from spring termite swarms to the fall invasion of box elder bugs and mice. When a guide mentions a specific pest, it links to the full profile. When it mentions treatment, it links to the relevant service.
