Bed Bug Control Guide

Signs of bed bugs

Small, rust-coloured spots on bedsheets — crushed bug or digested blood — are usually the first thing people notice, often along seams or the mattress edge. Live bed bugs are flat, oval, and reddish-brown, roughly the size of an apple seed, and tend to hide in mattress seams, headboard joints, and skirting boards near the bed rather than moving around openly during the day. A sweetish, musty odour in a heavily infested room is a further sign, though it usually only appears once numbers are already significant.

How bed bugs get into a home

Bed bugs are champion hitchhikers rather than something that flies or jumps in — they travel in luggage, secondhand furniture, and clothing, which is why hotel stays and buying used mattresses or sofas are the two most common ways they end up in a home. They don’t indicate poor hygiene; a spotlessly clean house can pick up bed bugs just as easily as any other, since the insects are drawn to warmth and a nearby blood meal rather than mess.

Health effects: bites and stress

Bites typically appear as small, itchy, red welts, often in a line or cluster, most commonly on areas exposed while sleeping like arms and legs. They’re not known to transmit disease, but the itching can be significant, and secondary skin infection from scratching is a real risk if bites aren’t left alone to heal. Beyond the physical bites, an ongoing infestation is genuinely stressful — disrupted sleep and the anxiety of an unseen problem in your bed are common and valid reactions, not an overreaction.

DIY control: what actually helps

A genuinely light, early-stage infestation can sometimes be managed with a combination of thorough vacuuming, steam treatment of mattress seams and furniture joints, and encasement mattress and pillow covers that trap any remaining bugs inside until they die off. Diatomaceous earth applied in cracks and along skirting can help as a supplementary measure, working mechanically rather than chemically.

Bed bugs are notoriously difficult to eliminate completely with DIY methods alone, though, because they hide in gaps a vacuum or spray can’t reach and because a single missed pregnant female can restart the whole problem. This is the one common household pest where professional treatment is genuinely the norm rather than the exception, even for people who successfully DIY most other pest problems.

Washing, heat, and vacuuming properly

Bed bugs and their eggs die at sustained temperatures above roughly 50°C, so washing affected bedding and clothing on the hottest cycle the fabric allows, then tumble drying on high heat, is one of the most reliable DIY steps available. Vacuum mattress seams, bed frames, skirting boards, and carpet edges thoroughly and frequently, sealing and disposing of the vacuum bag or emptying the canister outside immediately afterward rather than indoors.

When to call a professional

Given how easily bed bugs spread and how resistant they can be to DIY treatment, it’s reasonable to call a professional as soon as you’ve confirmed an infestation rather than waiting to see if home methods work first. This is especially true in flats and shared buildings, where bed bugs can move between neighbouring units through wall cavities and shared walls, meaning a full professional treatment plan across affected units is often the only way to fully resolve it.
