Imagine waking up with itchy red spots on your skin and no idea where they came from. You check your bed, your sheets look clean, and you don’t see anything crawling around. But what if the problem is hiding right under your nose—or more accurately, under your mattress?
Bed bugs are sneaky little pests that love to hide in cracks, crevices, and, unfortunately, your bed. Many people don’t even realize they have them until the infestation has already spread. If you’re wondering whether these unwanted guests have moved in, here are the most important signs to watch for.
Waking Up With Unexplained Bites
One of the first things people notice when they have bed bugs is strange, itchy bites on their skin. These bites usually show up in clusters or straight lines, often on areas that aren’t covered by clothing while you sleep—like your arms, neck, face, and legs.
Unlike mosquito bites, which tend to be random, bed bug bites are more organized. They also don’t always itch right away. Some people don’t react at all, while others may develop red, swollen spots that can take days to show up.
If you’re waking up with bites that weren’t there when you went to bed, bed bugs might be to blame.
Tiny Blood Stains on Your Sheets
Ever noticed small, rust-colored stains on your bed sheets or pillowcases? This could be a sign of bed bugs. These marks often come from crushed bugs or from bites that bleed slightly during the night.
The stains may look like tiny dots or smudges, usually near the edges of your mattress or wherever you tend to sleep. While other things can cause small stains—like a scratch or a tiny cut—seeing these marks regularly is a strong clue that bed bugs are around.
Dark Spots That Smear When Wiped
Bed bugs leave behind waste, and it’s not the kind of thing you want to find in your bed. Their droppings look like tiny black dots, almost like someone sprinkled pepper on your mattress. If you take a damp cloth and try to wipe them, they’ll smear because they’re made of digested blood.
Check the seams of your mattress, the corners of your bed frame, and even behind your headboard. If you find these dark smudges in multiple spots, you likely have bed bugs.
Live Bugs in Tiny Hiding Spots
The biggest giveaway that you have bed bugs is actually spotting one. But since they’re small (about the size of an apple seed) and good at hiding, most people don’t see them until an infestation gets worse.
Bed bugs are flat, reddish-brown, and slightly oval-shaped. They move quickly and usually come out at night. They hide in places like:
- Mattress seams and box springs
- Cracks in bed frames and furniture
- Behind wallpaper or electrical outlets
- Inside folded clothes or piles of clutter
If you want to be sure, try looking with a flashlight at night when they’re most active.
A Musty, Sweet Smell in Your Room
Some people say bed bugs give off a slightly sweet, musty odor. This happens when a lot of them are hiding in one place. It’s not always noticeable, but if your room suddenly smells different for no reason, it might be worth checking for other signs of an infestation.
Bed Bug Shells and Eggs
Bed bugs shed their outer skin as they grow, leaving behind pale, empty shells. You might find these near their hiding spots—like in mattress seams, behind furniture, or even in drawers.
They also lay tiny white eggs, about the size of a grain of salt. These eggs stick to surfaces and are often found in clusters. If you see them, it means bed bugs are actively breeding in your home.
When to Call in the Experts
If you spot signs of bed bugs, you might be tempted to handle the problem yourself. While vacuuming, washing bedding in hot water, and using mattress covers can help, bed bugs are incredibly tough to eliminate without professional treatment. They hide in tiny cracks, lay eggs that can survive for weeks, and can spread from room to room before you even realize they’re there.
The most effective way to get rid of bed bugs fast is with heat treatment. Unlike sprays or powders, heat reaches deep into furniture, walls, and carpets to kill bugs at all life stages. ThermoPest specializes in this method, wiping out entire infestations in just one visit. Instead of spending weeks battling bed bugs on your own, professional help can make sure they’re gone for good.
Where Do Bed Bugs Come From?
Bed bugs don’t just appear out of nowhere. They hitchhike from place to place by clinging to luggage, clothing, and furniture. Some of the most common ways they spread include:
- Hotels and Airbnb stays: Even the cleanest-looking places can have bed bugs hiding in the mattress or furniture.
- Used furniture: Buying a secondhand couch or mattress can bring bed bugs into your home without you realizing it.
- Public places: Movie theaters, buses, and office buildings can all have bed bugs, which can crawl onto your clothes and travel with you.
- Shared laundry facilities: Washing machines don’t always kill bed bugs, especially if clothes are moved from one basket to another.
How to Get Rid of Bed Bugs
If you’ve confirmed bed bugs are in your home, acting fast is important. Here’s what you should do:
- Wash and dry everything on high heat. Bed bugs can’t survive extreme temperatures, so throw all bedding, clothes, and curtains into a hot dryer for at least 30 minutes.
- Vacuum thoroughly. Go over your mattress, carpets, and any cracks where bed bugs could be hiding. Empty the vacuum outside immediately.
- Use mattress covers. Special bed bug-proof covers trap them inside, cutting off their food source so they eventually die.
- Declutter your space. Bed bugs love hiding in piles of clothes, books, and furniture seams. The fewer hiding spots, the easier it is to spot and remove them.
- Consider professional treatment. Home remedies can help, but they’re rarely enough to fully eliminate an infestation.
Don’t Ignore the Signs
Bed bugs are more than just annoying—they can disrupt your sleep, cause itchy bites, and be incredibly difficult to remove if you don’t catch them early.
If you notice any of the warning signs—bites, blood stains, dark spots, or strange smells—check your bed right away. The sooner you act, the easier it will be to get rid of them and keep them from spreading.
No one wants to share their bed with bugs. By staying alert and knowing what to look for, you can make sure these tiny invaders don’t make themselves at home.
