Bed bugs travel by hitchhiking. They crawl into bags and clothes, then ride home with you. The good news is that a few calm habits cut the risk a lot. This guide covers what to check on arrival, how to unpack, how to wash your clothes, and when a monitor helps.

Check the room before you unpack

First, keep your bags off the bed and the floor. The US Environmental Protection Agency advises using the luggage rack when you pack or unpack, rather than setting a case down on the bed or floor. Also look at the rack itself, because bugs can hide in its joints and straps.

Next, check the mattress and headboard before you sleep. Pull back the sheets and look along the seams and corners of the mattress. Then peek behind the headboard if you can reach it. A torch on your phone is enough for this.

You are looking for tiny dark spots, which can be droppings, along with live bugs and shed skins. Our guide to the signs of bed bugs shows what each one looks like. If you find them, ask for a different room, and ask for one that does not share a wall with the first.

What to do with your luggage

Keep your case closed and off soft furniture while you stay. If you can, leave it in the bathroom or on a hard surface well away from the bed. Zip clothes into bags inside the case, because a sealed layer gives bugs fewer places to hide.

On the day you leave, check the case again before you close it. Look in the seams, pockets and wheels. However, do not rely on one quick look, because bed bugs are small and good at hiding. That is why the steps at home matter just as much.

Unpack safely at home

Do not carry your case into the bedroom. The EPA suggests you unpack directly into a washing machine and inspect your luggage carefully. Do this in a hallway, utility room or garage, on a hard floor, so a stray bug is easy to see.

Then store the empty case away from where you sleep. The EPA advises basements and garages, and says never to keep suitcases under the bed. Our post on checking second-hand furniture before it comes indoors uses the same idea of inspecting at the door.

Wash and dry your clothes the right way

Heat is what kills bed bugs, so the dryer matters more than the wash. The EPA notes that time in a dryer at high temperatures kills them, while washing alone will generally not. In other words, never wash on a cool cycle and leave it there.

The NHS gives clear steps for infested items. It advises a hot wash at 60C, followed by a tumble dry on a hot setting for at least 30 minutes. Check each care label first, because some fabrics will not take that heat.

For items you cannot wash, the NHS suggests sealing them in a bag and putting them in the freezer for 2 to 3 weeks. Bear in mind that this takes patience, and a freezer cannot treat a whole room. If you ever need whole-room treatment, read our comparison of heat and chemical bed bug treatment.

When to set monitors after a trip

Monitors do not stop bugs coming in. They help you notice activity early, which makes any problem easier to deal with. Our guide to what traps can and cannot do explains that limit in more detail.

Set one if you stayed somewhere you were unsure about, or if you saw anything suspicious on the trip. Also set one if you wake up with new bites that you cannot explain. Put bed leg interceptors under each bed leg first, because they catch bugs that climb up or down the legs.

Next, add sticky traps near the bed and along walls where bugs might travel. Active monitors use a lure to draw bugs in, so they suit rooms where you want extra cover. Our how to use guide covers placement and checking routines. For a wider comparison, see the best bed bug traps overview.

Check your monitors on a regular routine. A clean trap is a good sign, but it is not proof that you have no bed bugs. Bites also have many causes, so keep an open mind until you have a real sighting.

If you do find bed bugs

Do not panic, and do not start spraying. The NHS says bed bugs are very difficult to get rid of yourself, because they are hard to find and some resist insecticides. It advises contacting your local council or a pest control service.

A trained inspector can confirm what you have and the extent of it. Our post on professional bed bug inspection in the UK explains what to expect from a visit. After any treatment, keep checking, as described in monitoring after bed bug treatment.
