Identification, signs & where to look
What it looks like
Adult bed bugs, Cimex lectularius, are wingless, flattened, oval insects, typically about 4–6 mm long and reddish-brown after feeding. Eggs and early nymphs are much smaller. Bites alone cannot confirm bed bugs.
Evidence to check
- Live insects or shed skins
- Dark spotting around mattress seams and frames
- Repeated bites can occur but do not prove bed bugs
- Eggs or harbourage signs in cracks
Common locations
- Mattress seams, bed frames and headboards
- Bedside furniture, skirting, cracks and fixings close to where people sleep
- Upholstered seating and adjoining rooms in established infestations
Lifecycle, lookalikes & why it appears
Lifecycle and seasonality
Bed bugs develop from egg through several nymphal stages to adult, taking blood meals between moults. Heated buildings allow activity throughout the year.
What can look similar?
- Fleas: laterally flattened jumping insects, often linked with pets
- Carpet beetle larvae: hairy fabric pests that do not blood-feed
- Skin reactions from non-pest causes; bites alone are not diagnostic
Why it appears
Bed bugs are usually introduced in luggage, furniture or belongings and then hide close to resting hosts. Infestation is not proof of poor hygiene.
What you can do now
- Look for live bugs, shed skins, eggs and dark spotting rather than relying on bites
- Avoid moving bedding or furniture to other rooms
- Reduce clutter and make the bed area accessible for inspection
Do not use agricultural, veterinary or unapproved chemicals indoors; do not rely on smoke bombs/foggers as a substitute for a proper inspection; do not discard furniture without containing it and considering how it will be removed.
When professional help makes sense
Professional treatment is usually the best route once bed bugs are confirmed, especially where more than one room or adjoining accommodation may be involved.
What treatment normally involves
A professional programme normally starts with a detailed inspection, preparation instructions and a treatment plan that may combine residual products, physical methods, monitoring and follow-up. More than one visit is common.

Bed-bug work is usually priced by affected rooms, treatment method, preparation complexity and follow-up. Very cheap single-visit claims should be compared carefully with the proposed inspection and revisit plan.
Read the cost guide →Frequently asked questions
Do bites prove bed bugs?
No. BPCA specifically advises looking for physical evidence such as insects, shed skins, eggs and spotting because bites can have many causes.
Can bed bugs live in a clean home?
Yes. They need access to a host and harbourage, not dirt; hygiene alone does not prevent introduction.
Use evidence before choosing treatment.
If the signs do not match cleanly, use the visual Pest Finder or get professional identification rather than treating a guess.
