What attracts bed bugs?

People often assume bed bugs are attracted by mess, food crumbs or dirt — and worry that an infestation says something about their home. It doesn’t. Bed bugs feed on blood, not food scraps, and what draws them is a sleeping human, not a dirty room.

What actually attracts bed bugs

• Body heat — they sense the warmth of a sleeping body nearby
• Carbon dioxide — the CO2 you breathe out while you sleep signals a host is close
• You being still — the quiet, predictable hours of sleep are when they feed

In other words, the thing that “attracts” bed bugs is simply a person asleep in a bed. That’s why even immaculate homes and hotels get them.

Does clutter attract bed bugs?

Clutter doesn’t attract bed bugs, but it does help them — a cluttered room gives far more cracks and crevices to hide in, and makes both inspection and treatment harder. So while a tidy room won’t keep them away, reducing clutter is still worth doing if you’re dealing with an infestation.

Myths worth dropping

• “Only dirty homes get them” — false; hygiene is irrelevant to bed bugs
• “They’re attracted to certain blood types” — there’s no reliable evidence for this
• “Leaving a light on keeps them away” — false; they’ll feed in light if they’re hungry enough
• “Food left out draws them” — false; they don’t eat food

What this means for keeping them away

Since you can’t make yourself less appealing to a bed bug, prevention isn’t about deterrents — it’s about not bringing them in, and catching them early if you do. Check hotel beds before unpacking, keep luggage off the floor, hot-wash clothes after trips, and inspect second-hand furniture. Our guide to avoiding bed bugs from travel has the full routine.
