Bed bugs are one of the most unpleasant pests you can bring into your home — and one of the hardest to get rid of once they settle in. The good news? The sooner you spot the warning signs, the better your chances of stopping them before they take over.
How do bed bugs get into your home?
A lot of people assume bed bugs only show up in dirty homes. That's a myth. They can turn up almost anywhere, because most of the time we carry them in ourselves.
The most common ways they hitch a ride:
- in your suitcase or clothes after traveling,
- on secondhand furniture and mattresses,
- from dorms, hotels, or vacation rentals,
- in apartment buildings, moving from neighboring units through wall cracks or along pipes and cabling.
Bed bugs don't jump and they can't fly — but they are exceptionally good at hiding, which is exactly why they so often go unnoticed.
How to tell if you have bed bugs
The first warning sign usually isn't the insect itself — it's the bites.
Signs that point to a bed bug problem include:
- itchy bites lined up in a row on your skin,
- tiny black dots (droppings) on the mattress or bedding,
- shed skins left behind,
- small blood spots on the sheets,
- a faintly sweet, unpleasant smell in heavier infestations.
During the day they usually hide in mattress seams, bed frames, behind electrical outlets, or in the gaps of furniture.
What to do when you find bed bugs
1. Wash textiles on a high temperature
Wash all bedding, blankets, pillowcases, and any washable clothing at at least 140 °F (60 °C), then dry them on a high heat setting. The heat kills both the bugs and their eggs.
2. Vacuum everything thoroughly
Vacuum the mattress, bed frame, baseboards, furniture, and every crevice you can reach. Afterward, immediately empty the vacuum bag or canister into a sealed bag and throw it out.
3. Use a steam cleaner
Bed bugs can't survive high heat. Hot steam can reach and destroy the ones hiding deep inside mattresses, upholstery, and furniture.
4. Treat with a targeted insecticide
If the infestation is still in its early stages, products made specifically for bed bugs can help. Always follow the instructions on the label, and focus on their hiding spots.
5. Call a professional for serious infestations
Bed bugs are one of the most resilient household pests out there. If they've spread to several rooms, or they keep coming back no matter what you do, professional extermination is usually the only way to be truly rid of them.
How to stop them from coming back
After every trip, always check your suitcase and clothes before you bring them into the bedroom. Only take home secondhand mattresses or upholstered furniture after inspecting them carefully. It also pays to vacuum around the bed regularly and to check the mattress seams from time to time.
Bed bugs are stubborn, but spotting them early and treating them properly gives you a real chance of getting rid of them before they ever have the chance to multiply.
How quickly do bed bugs spread?
They can spread fast if left unchecked, especially moving into multiple rooms or returning again and again. That's why early detection is so important.
Does a clean home protect you from bed bugs?
No. Bed bugs can appear in any home, because we usually bring them in ourselves — often after traveling or from secondhand furniture. Cleanliness alone won't keep them out.
What temperature kills bed bugs?
High heat is your best weapon. Washing textiles at at least 140 °F (60 °C) and using hot steam destroys both the bugs and their eggs.
When should I call a professional exterminator?
If bed bugs have appeared in several rooms or keep returning despite your efforts, professional extermination is usually the only reliable way to eliminate them for good.
