Where else to look
Once you finish scanning the bed, you’ll want to check other areas of your room. Here's what to look at, and where in your room to search.
The mattress and bed frame. The most obvious spot to look for bed bugs is in the mattress, but spotting them is a little more involved than just picking the mattress up and looking for dark spots. Bed bugs tend to hide in the joints of the frame and along the slats. So inspect those with a flashlight first. Then look in the crevices of the headboard, in the intricate details and design, then along the mattress seams and in the zipper. If all is clear there, pick up the mattress and look under it, which was probably the only move you'd thought of until now.
Sofas and throw pillows. "Plush pieces of furniture bugs" is too unwieldy a name, but these creeps range far beyond mattresses and headboards. Quite often, you'll find them in other soft seats but NOT in the bed. Take a look along the seams, inside the slip cover, and along the zippers of any decorative pillow or sofa cushion.
Closets and floorboards. Bed bugs don't even need soft, cushy spaces to find a home. They can be hiding in your closet, which can ultimately lead to that unfortunate clothes-boiling we mentioned earlier to try and get them killed. Check the spots where floor boards or floor molding meet the wall. These little corners are popular hangouts for bed bugs. In the closets, take a look at the seals of the doors and drawers, as well as the joints and corners of the closet. Basically, anywhere you might find a spider web, you might also find bed bugs.
