A bed bug infestation can be an absolute nightmare to deal with, so it’s crucial to know the early signs of bed bugs. The sooner you catch them, the easier it is to keep the problem from exploding into a full-blown infestation. Because bed bugs are sneaky and tiny, understanding what to look for gives you the upper hand. RELATED: Bug Bites 101: 10 Common Bites and What They Could Mean
Baby bed bugs (nymphs) are nearly invisible. They are tiny, pale, and fast-moving. Adult bed bugs are about the size of a flaxseed and can swell to the size of an apple seed after feeding. They are flat, oval-shaped, and reddish-brown.
They’re often confused with spider beetles, carpet beetles, and cockroach nymphs, so spotting confirmation signs of bed bugs is key.
To learn more about them, check in with the Centers for Disease Control.
If you’ve ever had a bed bug infestation, they may seem like they appear out of nowhere. But bed bugs usually spread from other infested areas, according to the Environmental Protection Agency (EPA). You can pick them up without knowing; they hitchhike like pros.
They’re common in:
Hotels
Multi-unit buildings
Shared accommodations
Public transportation
As long as people come and go, bed bugs travel with them.

Though bed bugs don’t like to wander and can’t fly, it’s easy to pick them up from somewhere that’s infested. They can reside in furniture, clothing, bags, and luggage.
They can hide in:
Luggage
Clothing and laundry
Furniture (new or pre-owned)
Bags and backpacks
If you live in an apartment, bed bugs can spread from unit to unit through walls, electrical outlets, and vents.

These are the early signs of bed bugs pest experts say show up first:
When you roll over a bed bug after it feeds, it can leave rust-colored specks or smears on sheets and pillowcases.
Bed bug droppings look like tiny pepper-like dots that may bleed into fabric like marker stains.
Check:
Mattress seams
Bed frame joints
Headboards
As bed bugs grow, they shed their exoskeletons. These casings are translucent, yellowish, and found near hiding areas.
A pregnant bed bug lays 1–7 eggs per day. Their eggs are pin-sized, sticky, and found on flat or hidden surfaces.
If you see eggs → there’s already a nest somewhere.
If you spot one…there are more.
Experts say seeing a single bed bug usually means a bigger infestation is already happening.
Bites are not a reliable early sign of bed bugs. They look like mosquito bites, and reactions differ from person to person — some people don’t react at all.
Bed bugs don’t like to move around during the day, so they often find comfortable hiding spots and hunker down. That means your best bet for catching an early infestation is by seeking them out. When they’re not feeding on humans, bed bugs can be found in various places.
Top hiding spots include:
Mattress seams and box spring edges
Cracks in bed frames and headboards
Under cushions and couch seams
Electrical outlets and baseboards
Behind the wall decor and loose wallpaper
Inside drawer joints
Use a flashlight and a card to scrape along seams.
