Fifteen minutes with a torch and you will know. Here is exactly where to look and what each thing you find actually means.
The mattress seams and piping first, top and bottom. Then the bed frame joints and slat undersides, then the headboard where it meets the wall.
You are looking for dark ink-like spots, pale translucent shed skins, and live insects — all concentrated in seams and crevices rather than out in the open.
| Sign | What you are seeing | Reliability |
|---|---|---|
| Dark ink-like spots | Digested blood on fabric or wood | High, in seams |
| Pale translucent casings | Shed skins from moulting | High |
| Live insects | Flat, oval, reddish-brown, apple-pip sized | Conclusive |
| Small blood smears on sheets | A bug crushed after feeding | Suggestive |
| A sweet musty smell | Heavy established infestation | Suggestive |
| Bites | A reaction, which varies enormously | Low on its own |
Concentration matters as much as presence. Bed bug evidence clusters in seams, joints and crevices — dark specks scattered randomly across open fabric are more likely to be something else.

View Bed Bug Control Harrow →People react to bed bug bites very differently. Some develop obvious itchy welts within hours; a significant proportion show no visible reaction at all, and reactions can also be delayed by days.
So two people in the same bed can have entirely different experiences, and one person covered in bites while their partner has none is a common and confusing scenario rather than evidence that only one of them has a problem.
Bites tell you somebody reacts to something. The mattress seam tells you what it is.
If you are being bitten but a careful search turns up nothing:
A sensible habit rather than paranoia. After a guest has used a room, or after you have been away, strip the bed, wash the linen hot, and give the mattress seams a two-minute look. It costs nothing and catches problems while they are still one room.
A very different pest, the same published approach — wasp nest treatment across Harrow is £90 fixed cost, guaranteed.
Mattress seams and piping, top and bottom, then frame joints and slat undersides, then the headboard.
Small dark ink-like dots on fabric or wood — digested blood — concentrated in seams and crevices.
No. Reactions vary enormously, some people show nothing at all, and plenty of things bite.
People react very differently to bed bug bites. It is common for one person to react obviously and another not at all.
Empty translucent casings left behind as bed bugs moult. They are a reliable indicator.
Possibly — flea bites tend to be around ankles and lower legs, and the insects jump.
