April 4, 2026 1

Every homeowner encounters unwanted insects at some point. Knowing how to identify these common household bugs is the first step toward effective pest control.

Cockroaches

Cockroaches are among the most common household pests. They have flat, oval bodies and long antennae. Look for them in kitchens, bathrooms, and other warm, moist areas.

Ants

Ants enter homes seeking food and water. The key to identification is noting their size, color, and where you find them. Carpenter ants are large and black, while sugar ants are small and brown.

Spiders

Most household spiders are harmless and actually help control other pests. However, be cautious of brown recluses and black widows.

Bed Bugs

These tiny, reddish-brown insects hide in mattress seams and furniture crevices. Signs include small blood spots on sheets and itchy bite marks.
