7 Warning Signs You Have Bed Bugs (and What to Do Next)

By Bed Bug Solutions Team May 20, 2025 6 min read

Bed bugs are expert hitchhikers and even better at hiding, so an infestation is usually well underway before anyone spots a live bug. The good news: they almost always leave clues. Here are the seven signs we check first on every inspection in Gresham.

1. Bites in lines or clusters

Bed bug bites often appear in rows or small clusters on skin exposed while you sleep — arms, shoulders, neck, and legs. Reactions vary from person to person, so bites alone aren’t proof, but paired with other signs they’re a strong clue.

2. Rust-colored spots on bedding

Tiny reddish-brown or dark spots on sheets, pillowcases, and mattress seams are digested blood. Check the piping and seams of your mattress and box spring first — that’s where activity shows up earliest.

3. Shed skins and eggshells

As bed bugs grow they molt, leaving pale, translucent shed skins. Alongside them you may find tiny white eggs or eggshells wedged into seams, cracks, and screw holes.

4. A sweet, musty odor

Heavier infestations can give off a faint, sweet, musty smell from the bugs’ scent glands. If a room smells “off” near the bed, it’s worth a closer look.

5. Live bugs in the seams

Adult bed bugs are about the size of an apple seed, flat, and reddish-brown. Peel back mattress seams and inspect the headboard, bed frame joints, and nearby outlets with a flashlight.

  • Small blood smears where you’ve rolled onto a bug
  • Dark speckling along mattress piping and box-spring corners
  • Activity spreading to nightstands, sofas, and baseboards

What to do if you spot the signs

Don’t start bagging everything or spraying store-bought products — that often scatters bed bugs to new rooms and makes treatment harder. Book a professional inspection. We confirm the problem, map how far it’s spread, and give you a fixed-price plan before any work begins.
