See what the evidence says about heat, breath, fabric and clutter, and which common myths about attraction are wrong." tags: [bed bugs, UK, Identification] categories: [Identification] --- ## The short answer: people Bed bugs feed on blood. That is the whole reason they come into a home. They go for the people and animals they feed on, not to food crumbs, spills or rubbish. Many people hear that bed bugs only live in dirty places. As a result, they feel ashamed or look for the wrong cause. The evidence points the other way, so it helps to separate fact from repetition. ## What draws them to a host The University of California IPM Program says bed bugs locate hosts through heat and carbon dioxide. Carbon dioxide is the gas we breathe out. A sleeping person gives off both, all night, in one place. The same source notes that monitoring devices may use heat, carbon dioxide, host odours, pheromones or a mix of these to lure bed bugs. That tells us the insects respond to several cues. It does not mean a single trick will keep them away from a bed. The University of Kentucky says bed bugs are active mostly at night. That matches the pattern most people see: bites appear after sleep, and the insects are gone by morning. You can read more about the marks they leave in our guide to [bed bug bites](/identify-bed-bugs/bed-bug-bites/). ## Myth: dirt and mess bring bed bugs The NHS says bed bugs are found in both clean and dirty places. The CDC goes further and says how clean a place is does not determine whether bed bugs are present. It adds that infestations happen everywhere, from five-star hotels to shelters. The University of Kentucky makes the same point in a different way. Unlike cockroaches and flies, bed bugs do not feed on filth, so cleanliness rarely explains an infestation. Therefore, a spotless home can still have bed bugs. Equally, a cluttered home has not "earned" them. Blaming the person helps nobody, and it can delay the check that matters. ## Myth: clutter attracts them Clutter does not attract bed bugs. The sources we checked do not say that it does. However, clutter can still make a problem harder to deal with. Bed bugs have flat bodies. The University of Kentucky says they fit into crevices no wider than a toothpick. Piles of clothes, boxes and papers near a bed give them more cover. They also give you more to inspect and more to wash or bag during treatment. So tidy up for a practical reason, not a moral one. Fewer hiding places make [where bed bugs hide](/identify-bed-bugs/where-bed-bugs-hide/) easier to check. Our [early signs guide](/identify-bed-bugs/early-signs/) shows what to look for once the area is clear. ## Why fabric and wood matter UC IPM says bed bugs prefer fabric or wood surfaces to metal or plastic. That explains why mattress seams, wooden bed frames, headboards and upholstered furniture come up so often. The CDC says bed bugs can travel over 100 feet in a night but tend to live within 8 feet of where people sleep. In other words, they settle close to the host. A bed, a nearby chair and the wall behind a headboard are the first places to look. ## Do other insects get mistaken for them? Yes, and this is a common source of confusion. Bites on their own cannot prove bed bugs, because other biting insects leave similar marks. Our comparison of [bed bugs and fleas](/identify-bed-bugs/bed-bugs-vs-fleas/) explains how to tell them apart. The best evidence is the insect itself. The NHS describes adults as around 5mm long and dark yellow to brown or red. Look for shed skins, small brown spots and blood marks on bedding as well. Pale eggs are harder to spot, and the guide to [bed bug eggs](/identify-bed-bugs/bed-bug-eggs/) shows what they look like. ## A simple check you can do tonight You do not need special tools. A torch and a few minutes are enough, and the steps below follow the signs the NHS lists. 1. Strip the bed and look along the mattress seams and tags for live insects, shed skins and dark spots. 2. Check the bed frame joints and the back of the headboard, since bed bugs tend to live close to the sleeper. 3. Look at blood marks on sheets. The NHS says blood spots can come from bites or crushed bugs. 4. Note anything you find, and take a clear photo. It helps if you later ask for advice. If you find nothing, that is useful too. However, one clear night does not rule out a problem, because the insects hide by day. ## Can you make your home less attractive? You cannot switch off heat and breath, so you cannot make a bedroom unattractive to a bed bug. What you can do is cut the chances of bringing them in, and spot them early. - Check second-hand furniture and luggage before bringing them inside. - Inspect the mattress seams and bed frame now and then. - Keep the area around the bed clear, so a check takes minutes. How long they can wait between meals also matters, and our guide on [how long bed bugs can live without feeding](/identify-bed-bugs/how-long-without-feeding/) covers that in detail. ## What to do if you find them Do not blame yourself, and do not rush to buy sprays. The NHS recommends professional pest control because bed bugs can be hard to find and may resist some insecticides. Our [guide to identifying bed bugs](/identify-bed-bugs/) walks through the checks in order. If you rent, the council may offer help, and councils differ. For example, you can read about [council pest control in Manchester](/locations/manchester/) or [council pest control in Leeds](/locations/leeds/) to see how the route works in those cities. For another view, read [council pest control in Coventry](/locations/coventry/). This site is an information and referral service. It is not a pest control contractor.
