Bed bug identification guide
What Do Bed Bugs Look Like?
Adult bed bugs are flat, oval, reddish-brown insects about the size of an apple seed. Look for the insect and the evidence it leaves near sleeping and resting areas.
Identification
Look for physical evidence, not bites alone
Bed bugs change appearance after feeding and young nymphs can be much smaller and lighter than adults. Use several signs together before deciding what you found.
Nymphs
Smaller and paler than adults. Recently fed nymphs may show a visible red abdomen.
Eggs
Tiny, pale, pearl-like eggs attached in protected seams, joints, cracks, or folds near activity.
Cast skins and spotting
Pale shed skins and dark ink-like dots along mattress seams, frames, headboards, or nearby furniture.
Room check
Where to look first
- Mattress piping, labels, and seams
- Box spring fabric, corners, and frame
- Headboard joints, screw holes, and wall contact points
- Couch and recliner seams, folds, and frame
- Nightstands and furniture closest to the bed
- Luggage and storage near sleeping areas
Common questions

No. They may hide in frames, headboards, couches, nearby furniture, trim, gaps, and other protected areas close to a resting person.
Do bed bugs look like ticks?
They can be confused with ticks, carpet beetles, roach nymphs, bat bugs, and other small insects. A clear photo or saved specimen helps.

Dark spotting can look like tiny ink dots and may smear when fresh. Rust-colored blood marks can also appear on bedding.
