One unintended consequence of creating a cozy, comfortable home is that it becomes an inviting habitat for creepy, crawly pests, including all manner of insects and rodents.

Here, I’ll discuss how to detect which pests have moved into your home, and then offer ways to evict them.

Since most pests prefer to avoid human interaction, you might not realize you’ve got a pest problem until it’s too late. For example, you’ll likely see mouse droppings on countertops long before you ever see a mouse. And, like most pests, if you see one mouse, you can be sure there are plenty more hidden from sight. And if squirrels or bats get into your home, you might not see them, but you’ll surely hear them scratching inside the walls and above ceilings.

Termites are the most destructive of all pests and they, too, can be difficult to detect until they start devouring your home. Of course there are plenty of pests—ants, cockroaches, gnats, moths, flies—that are easy to detect because you can see them scurrying around or flying through the air.

The good news is that once you’ve discovered and identified the pest, there are several very effective DIY solutions to eradicating the infestation. Here now, is a brief look at ways to control common household pests.

Mice and other small rodents typically enter our homes during the winter as they look for a warm, dry place to live. Then, come spring, they usually move outdoors to forage and raise a family—usually, but not always. To keep mice from moving in, start by sealing up all holes, cracks and gaps around the exterior of the house. Stuff large spaces with stainless steel wool pads or rolls of stainless steel wool. Then spray in some expanding foam sealant to create a near-impenetrable barrier.
