Photo confirmation checklist

Use these visual checks to compare the pest, the evidence, and the likely source area before choosing a treatment path.

Mattress and bed frame seams

First check

Mattress and bed frame seams

Start where people sleep: seams, piping, labels, box spring edges, headboards, and bed frame joints.

Bed Bug Bites

Evidence guide

Bed Bug Bites

Use this evidence type to confirm whether the sign fits the pest problem.

Quick answer

What to know first

Start with mattress seams, box springs, bed frames, headboards, and nearby furniture. Then inspect sofas, luggage, baseboards, curtains, outlets, and shared-wall cracks if evidence continues.

Check first

  • Mattress seams, piping, labels, tufts, and box spring edges
  • Headboards, bed frame joints, screw holes, and nearby nightstands
  • Sofas, luggage, baseboards, curtains, and wall gaps near sleeping areas

Avoid this

  • Only checking the top of the mattress
  • Moving infested items before photographing evidence
  • Using foggers before mapping where activity is concentrated

Overview

Bed bugs hide close to where people rest, but they can spread into cracks, furniture joints, luggage, wall gaps, and nearby sofas. A careful inspection follows the resting site outward instead of checking random rooms first.

Key signs to check

Dark fecal spots on seams, wood joints, or fabric folds
Tiny eggs or pale shed skins in protected cracks
Live bugs in mattress seams, headboards, sofas, or luggage folds
Repeated bites after sleeping paired with physical room evidence

What to do now

  1. 1Use a flashlight and card edge to inspect seams, joints, and cracks.
  2. 2Photograph stains, eggs, shed skins, or insects before cleaning.
  3. 3Bag suspect fabrics before moving them through the home.
  4. 4Install interceptors or monitors after the first inspection pass.

Prevention checklist

Keep beds slightly away from walls during monitoring.
Use encasements to simplify future inspection.
Inspect luggage and used furniture before bringing items indoors.
Reduce clutter near resting areas so hiding places are easier to find.

When to call a professional

Call a professional when live bugs, eggs, or repeated evidence are found, especially in more than one room.

FAQ

Can bed bugs hide in walls?

Yes. They can use cracks, baseboards, outlets, and shared-wall gaps when activity grows or spreads.

Should I inspect sofas too?

Yes, especially if people sleep or rest there, or if bites occur away from the bedroom.
