How to Tell If You Have Bed Bugs

Itchy bites in the morning? The signs of bed bugs, where to check, and what to do (and not do) if you find them.

Short answer

You probably have bed bugs if you wake up with itchy bites in lines or clusters, find small blood spots on your sheets, see black ink-like dots along mattress seams, or spot small reddish-brown bugs or pale shed skins in the seams of your mattress, bed frame or headboard. Check those areas with a torch, especially the corners and seams.

Signs of bed bugs

  • Itchy red bites, often in a line or cluster on the arms, neck, shoulders or legs
  • Small rust-coloured blood spots on sheets and pillowcases
  • Black dots (droppings) along mattress seams, bed frames and headboards
  • Live bugs: flat, oval, reddish-brown, about the size of an apple seed
  • Pale shed skins and tiny white eggs in seams and crevices
  • A sweet, musty smell in heavy infestations

Where do bed bugs hide?

Bed bugs hide close to where people sleep or sit for long periods: mattress seams and piping, the bed base and frame, headboard joints, bedside tables, skirting near the bed, plug points, curtains and couches.

What to do if you find bed bugs

  • Don't move to another room to sleep: bed bugs will follow and spread
  • Don't throw furniture out without bagging it, as it spreads bugs
  • Wash bedding and clothing on a hot cycle and tumble dry
  • Vacuum around the bed and empty the vacuum outside
  • Book a professional treatment with a follow-up visit

How did I get bed bugs?

Bed bugs travel in luggage, handbags, second-hand furniture and clothing. Having them is not a sign of a dirty home. Hotels, guesthouses, hostels, public transport and visitors are common sources.

Frequently asked questions

Can I get rid of bed bugs myself?

It is very difficult. Bed bugs hide in tiny cracks and their eggs resist many treatments. A professional treatment with a follow-up is the most reliable approach.

Do bed bug bites appear immediately?

Not always. Some people react within hours, others after several days, and some people do not react at all.

Do I need to throw away my mattress?

Usually not. Mattresses can normally be treated. A mattress encasement can help after treatment.
