One of the most common signs that people notice when they have bed bugs are the bites. Before marks appear on their body, people generally don’t even consider bed bugs. The bites that will appear if you have bed bugs are red, flat welts that will be in zigzag lines, straight lines, or a small cluster. You won’t get a disease from the bugs, but they are itchy and can lead to an infection if irritated by scratching until blood appears. The bites typically appear on arms, legs, shoulders, or any skin that’s left naked while sleeping. This differs from other bugs during warm weather that might bite around the ankles, like fleas, chiggers, and mosquitos.

The Bed

An infected bed is the second telltale sign that something has infiltrated your sheets. After biting you, there will be small dried blood stains on the edges and corners of the bed. As they mature, bed bugs shed their skin, so the second sign would be finding their circular tan exoskeletons in the covers. Look for bed bugs on the mattress corners, around the folds, and the boxspring.

These will appear on the mattress, box spring, or sheets as dark or black stains that look like a felt tip pen has bled onto the fabric. These spots are digested blood, or fecal matter left behind after the bed bugs have fed. To confirm whether you do have a bed bug infestation, you can wipe the spots with a wet rag and if they smear, it is bed bug feces.

Eggs and Empty Eggshells

Bed bugs can lay a large amount of eggs, so they remains of the egg shells can be seen fairly easy. A female bed bug can lay up to five eggs a day so if not caught early, a bed bug infestation can lead to a large problem quite quickly. Look closely at the seams on your mattress and box spring for small, translucent shells.
