How to identify a bed bug infestation
Check your mattress for bedbugs.
Bedbugs tend to live and migrate towards mattresses, box springs, bed frames, and headboards. These are small, brownish red insects that are oval in shape.
They live off of the blood in animals and humans. Look around the edges of your mattress, the creases of your sheets, and pillowcases.
