If you find bloodstains on your bedding or nearby objects, bedbugs are probably present. These stains are usually dark red, rust-colored, and smeared, and they’re caused by the bedbugs’ excrement. These stains tend to appear near the foot of the bed and on the pillowcase. They can spread out to cover a large area, and they eventually fade to a lighter brown color.
Bedbugs feed primarily on the blood of mammals, including humans. However, they will also feed on other warm-blooded animals. The common bedbug lives for two to fourteen days before it needs to feed again. During the feeding period, the bedbug stabs the host with its beak. Feeding usually takes three to twelve minutes, and the bedbug will stop feeding if the host disturbs it. Bedbug bites typically appear in rows.
If you think you have a bedbug infestation, the best way to get rid of them is to clean them thoroughly. The first thing to do is to remove any cushions or bed covers. Check for bites along the seams of the furniture and look for rusty stains. Check any cracks on the headboard, baseboards, and upholstered furniture. Be sure to remove cushion covers and check the seams to see if any bugs are hiding inside.
Bedbugs also leave fecal marks on your bed. These are small, black, and look like ink dots from a marker or pen. These fecal marks are primarily made of digested human blood. They look rusty and have a foul smell.
