What are three signs you might have bed bugs?

Three signs you might have bed bugs include bites on your skin, physical evidence on your bedding, and finding live bugs or shed skins in hiding places, though bites alone are not definitive because they resemble mosquito and flea bites. First sign is itchy, red welts on exposed skin that appear overnight, often in a line, zigzag, or cluster pattern on arms, shoulders, neck, and legs, caused by bed bugs feeding for 5 to 10 minutes, though some people do not react at all. Second sign is physical evidence on your bed and nearby furniture, such as small rust-colored or reddish stains on sheets and pillowcases from crushed engorged bugs, tiny dark spots that look like ink dots from bed bug feces on mattress seams, sheets, box spring edges, and walls near bed, and a sweet, musty odor in heavily infested rooms. Third sign is finding live bugs themselves or their shed skins and eggs, live bed bugs are small, flat, oval, reddish-brown insects about apple seed size that hide during day in mattress seams, box spring cracks, headboard crevices, behind baseboards, and in furniture joints, and you may find translucent shed skins and tiny white eggs about 1 mm in those crevices. To confirm, inspect mattress seams with flashlight at night between 2 AM and 5 AM when they are most active, use interceptor traps under bed legs to catch bugs, and contact professional pest control for inspection.
