This isn't about how clean your home is
Noticing any of the below doesn't say anything about the home, bed bugs are hitchhikers that show up in clean and tidy places just as often as anywhere else.
What they look like
An adult bed bug is small, flat and oval, roughly the size and color of an apple seed, reddish-brown, without wings. After feeding, they appear more swollen and a duller red. Younger stages are smaller and paler, closer to a translucent tan, which is part of why they're easy to miss or mistake for something else. Shed skins, thin, pale, husk-like outlines left behind as they grow, are often found in the same places as the insects themselves and are just as useful a sign.
Marks on bedding & furniture
Small reddish-brown or dark spots along a mattress seam, box spring, or the piping on a cushion are one of the more recognizable signs, these are typically a residue rather than a stain that wipes away cleanly. Tiny dark specks the size of a period, clustered near the same seams, are another common find. Neither of these is exclusive to bed bugs, but the combination of both, concentrated near the bed, is a reasonable reason to have things checked.
What's commonly mistaken for them
Carpet beetles, spider beetles and a handful of other small household insects are frequently mistaken for bed bugs on sight, especially by size and color alone. Lint, thread, and small bits of dark debris in a seam are often mistaken for shed skins or droppings. This is exactly why an inspection is useful even when you're fairly confident about what you're looking at, ruling something out is a completely normal, and common, outcome.
Why bites alone aren't proof
Reactions to bites vary enormously from person to person, some people show a clear pattern of marks, others show nothing at all even with an active problem in the home, and many insects and skin reactions can look similar to each other. Because of that range, bites by themselves are one of the least reliable ways to identify what's actually happening. Anyone concerned about a bite or a reaction should speak with a medical professional; this page can't and won't speak to what any particular mark on skin means.
What to do next
If you've noticed any of the above, the most useful next step is usually an inspection rather than guessing or trying a store-bought product first, those commonly fail to solve the problem and can make it harder to find later. Leave the area as-is if you can, and have a specialist take a look before anything else changes.
Common questions
I found small brown bugs but no bites, could it still be bed bugs?
Yes, plenty of people notice the insects or marks on bedding well before, or without ever, noticing a bite.
Are the dark spots on my mattress definitely bed bugs?
Not necessarily, several things can leave similar marks. It's a reasonable enough sign to have checked, not a certain diagnosis on its own.
Can I identify them from a photo?
A photo can help narrow things down, but a hands-on inspection is far more reliable, especially for younger life stages that are easy to misidentify.
Does finding one bug mean there's a bigger problem?
Not necessarily, an inspection can tell you roughly how established, or not, the activity is.
I only see marks in one spot, is that unusual?
Not at all, activity is often concentrated in one area, especially early on.
Should I throw out my mattress if I see marks?
Not before an inspection. It's worth confirming what you're dealing with first, since replacing a mattress alone doesn't always solve the underlying issue.
Does an itchy bite mean I have bed bugs?
Not on its own, reactions vary a lot between people, and other things cause similar marks. Speak with a medical professional about the bite itself.
What if I can't find anything but still suspect something?
That's a normal reason to call: a specialist can check the places that are easy to miss on your own.
Not sure what you found?
Call and we'll talk it through, no pressure either way.
