Understanding what causes bed bugs is the first step to protecting your household. Unlike pests drawn in by food waste or poor hygiene, bed bugs travel the world in luggage, clothing and second-hand furniture. They are attracted to one thing: the carbon dioxide and warmth produced by sleeping humans.
How bed bugs get into your home
The most common route is travel. Hotels, hostels, holiday apartments and even high-end resorts can harbour bed bugs in mattress seams, headboards and upholstered furniture. If a bug or a few of its eggs end up in your suitcase, they come home with you. This is why outbreaks often begin in a bedroom shortly after a trip.
Second-hand furniture and clothing are another significant source. A mattress, sofa or bed frame left out for collection can look perfectly good on the outside while hiding an active infestation in its seams. Pre-loved items bought through online marketplaces carry a small risk too, particularly if you cannot inspect them thoroughly before bringing them indoors.
Shared living and multi-occupancy buildings create conditions where bed bugs can spread from one unit to another through wall cavities, along pipe runs and under doors. If a neighbouring flat has an untreated infestation, there is a genuine risk of bugs migrating into adjacent properties over time.
Visitors are a less obvious but real source. A guest whose own home has an infestation may unknowingly carry bugs in a bag or coat. Items purchased online and stored in a private home or shared warehouse before dispatch introduce a small element of risk in the same way.
Why hygiene alone does not prevent bed bugs
This is the most important point to understand. Bed bugs do not feed on crumbs, rubbish or standing water. They feed exclusively on blood, which means they will thrive in a spotlessly clean home just as readily as anywhere else. Regular vacuuming will not deter them, and general-purpose chemical sprays designed for other pests have little effect on a bed bug population.
Clutter can make an infestation harder to treat because it provides more hiding places, but clutter is not what causes bed bugs in the first place. You should not feel embarrassed about an infestation. Even five-star hotels deal with them from time to time, and the stigma attached to bed bugs has no basis in fact.
Warning signs to look for
If you suspect you may have introduced bed bugs, the earlier you check the better. Look for:
- Small dark spots on mattress seams, bed frames or skirting boards. These are faecal marks left by feeding bugs.
- Tiny pale yellow shed skins, roughly the size of a sesame seed.
- Rust-coloured smears on bedding from crushed bugs.
- Bites appearing in lines or clusters on exposed skin such as arms, shoulders and the neck. Not everyone reacts to bed bug bites, so the absence of itching does not rule them out.
If bites are causing significant swelling, spreading redness or any sign of a serious allergic reaction, contact NHS 111 or call 999 in an emergency. For mild bite reactions, keeping the area clean and avoiding scratching is sensible while you arrange treatment.
What to do once you suspect bed bugs
Do not delay. A single mated female bed bug can produce hundreds of eggs over her lifetime, and an infestation caught early is far simpler and less disruptive to treat than one that has been spreading for months.
Avoid moving bedding, mattresses or furniture around your home before treatment, as this risks spreading bugs to rooms not yet affected. Do not throw your mattress out either. Qualified pest controllers can treat mattresses in situ, and replacing it without treating the room will not resolve the problem.
