There are a few signs that you may have bed bugs:
Bites on your skin: Bed bugs typically bite the exposed skin on your neck, arms, legs, and face. The bites may be itchy and appear as small red bumps or welts.
Bloodstains on your sheets: Bed bugs can leave behind small, reddish-brown stains on your sheets, pillowcases, and mattress. These stains may be a sign that bed bugs have been crushed while you were sleeping.
Actual sightings of bed bugs: You may see live or dead bed bugs in the folds of your mattress, in the seams of your bedding, or on the floor near your bed.
A musty, sweet smell: Bed bugs release an odorous chemical that can give off a musty, sweet smell. This smell may be more noticeable in areas where bed bugs are concentrated, such as in your bed or on your bedding.
If you suspect that you have bed bugs, it is important to take steps to remove them as soon as possible to prevent the infestation from spreading.
