Bed Bug Inspection Checklist: Where to Look First

This bed bug inspection checklist shows you where to look first, what signs matter most, and how to inspect the places bed bugs are most likely to hide. Use it as a practical room by room guide so you can confirm the problem quickly and know what to do next if you find evidence of an infestation.

In the bedroom image below, the numbered points show the places bed bugs are most often found first. Start with the bed and the items closest to it, then work outward to nearby cracks, furniture, fabrics, and wall fixtures.

1

Check clock radios, phones, nightstands, and other items next to the bed. Inspect the underside, back corners, drawer joints, and any gaps where bed bugs can stay hidden during the day.

2

Inspect the mattress seams, piping, tags, and corner folds carefully. Look for dark spotting, shed skins, eggs, and live bugs, especially along the upper and lower edges.

3

Check the edges of outlets and the wall gap around them, especially the ones closest to the bed. Bed bugs can hide behind wall plates and nearby cracks.

4

Inspect the headboard where it meets the wall and along any seams or joints. If it is mounted tightly, use a card or similar flat edge to check narrow gaps.

5

Look behind picture frames and wall hangings near the bed. Pay attention to back edges, hanging hardware, and the wall area directly behind them.

6

Check curtains and drapes, especially folds, hems, pleats, and the fabric nearest the bed. These areas are easy to overlook during a quick inspection.

7

Inspect the baseboard behind and beside the bed. Focus on the gap where the baseboard meets the wall or floor, plus any nearby cracks.

8

Check pillows, pillow seams, zipper areas, and removable covers. If pillows are stored against the headboard or mattress, inspect them closely for spotting or shed skins.

Bed Bug Checklist Shows You Where They Hide

Use this checklist before you move furniture or begin treatment. Pull back bedding, inspect seams and tags, and focus on tight spaces close to where people sleep or rest.

Bed bugs hide in narrow gaps, so any place that can hold the edge of a credit card deserves a careful look.

  • behind baseboards
  • around door casings and window trim
  • along window sills and frames
  • behind electrical and telephone wall plates
  • where the floor meets the wall
  • around pipes and conduit openings
  • bed frames and headboards
  • seams, folds, tufts, and tags on the mattress and box spring
  • under nightstands and inside drawer joints
  • storage units near the bed
  • furniture with hollow legs or screw holes
  • seams of upholstered chairs and couches
  • folds and hems of drapes or curtains
  • alarm clocks and small electronics near the bed
  • behind loose wallpaper
  • behind picture frames and wall hangings

Inspecting the Mattress

The mattress and box spring are still the first places most people should inspect. Look closely at the seams, piping, tags, corner folds, and the underside of the box spring, because these tight areas give bed bugs shelter close to where people sleep.

If you find several signs together in one area, such as dark spotting, shed skins, eggs, and live bugs, that is much stronger evidence than a single mark by itself.

This is a live adult bed bug hiding in the corner of the mattress. Live bugs are the clearest sign of an active infestation.

2

These shed skins, also called cast skins, are left behind as bed bugs grow. Finding several of them in one place usually means the hiding spot has been active for a while.

3

These eggs and eggshells are another strong sign. Fresh eggs are small, pale, and sticky, while hatched shells look lighter and empty.

4

These dark spots are bed bug droppings. They often look like tiny marker dots and may smear if wiped with a damp cloth.

A mattress is one of the most common places to confirm an infestation because it combines heat, shelter, and easy access to a sleeping person. Compare what you find with our bed bug infestation signs and pictures guide.

The Top Signs You May Have Bed Bugs

  • Live bed bugs hiding in seams, folds, corners, or joints
  • Dark spotting on fabric, wood, or nearby surfaces that looks like tiny ink dots
  • Shed skins left behind as bed bugs grow from one stage to the next
  • Eggs and eggshells in protected cracks, seams, or folds
  • Rusty or reddish stains on bedding or the mattress from crushed bugs

Smell can sometimes be present in a heavier infestation, but it is not a reliable first sign and many people do not notice it at all. Use visual evidence first, especially live bugs, spotting, shed skins, and eggs.

What to Do If You Find Bed Bugs

If your inspection turns up live bugs, eggs, shed skins, or dark spotting in your home, go straight to our guide on how to get rid of bed bugs. It walks you through the next steps in order so you can start with a practical plan instead of guessing.

If you find evidence in a hotel, rental, or bed and breakfast, take clear photos before you move anything. You can send us photos for identification, and the pictures can also help with your documentation.

During inspection, wear gloves and handle suspect items carefully. That keeps the process cleaner and makes it easier to bag, photograph, or isolate what you find.

If you are convinced bed bugs are present but still have not found a live specimen, you can try a bed bug trap to catch one for proof, or bring in a bed bug sniffing dog.
