Where are these bugs coming from? I keep a clean house.

Sometimes it’s tough to remember that the bugs aren’t doing this just to drive us crazy. Most bugs only come inside when the outside becomes less hospitable. For example, during the summer, the heat dries up the ground and forces ants inside to search for new sources of moisture. In the winter, rats and mice find that many of their preferred food sources are hibernating. The cold sends many rodents inside to search for food and warmth.
