What a bed bug looks like in a photo
Adult bed bugs are small, flat, oval insects about the size of an apple seed, roughly 5 to 7 millimeters long. They are reddish-brown, have six legs and short antennae, and look flatter when unfed and rounder and darker after a blood meal. The tool compares your photo against these traits to gauge how well it fits.
- Flat, oval body about the size of an apple seed (5–7 mm).
- Reddish-brown color, darker and rounder after feeding.
- Six legs and short, straight antennae.
- No wings and no hard, shell-like wing cases such as a beetle has.
How to photograph a suspected bed bug
Bed bugs are small, so a close, sharp photo matters most. Get as near as your camera can focus without blurring, use bright light, and place the bug on a plain, light surface. Include a coin or the tip of a pen for scale. If you found it on a mattress seam or luggage, a second photo of that spot helps too.
Bed bug lookalikes to rule out
Several common bugs are mistaken for bed bugs. Fleas are smaller and jump, carpet beetles are rounder with patterned wing cases, and bat bugs look nearly identical without a microscope. Booklice, spider beetles, and young cockroaches also get confused with them. The tool flags these lookalikes so you can compare shape, size, and color side by side.
Checking for bed bugs while traveling
Hotels and rentals are a common place to spot bed bugs. Before unpacking, check the mattress seams, headboard, and upholstered furniture, and keep luggage off the bed and floor. If you find a suspicious bug or dark spotting, photograph it and run it through the tool before you assume the worst or move rooms.
What to do about a positive result
A photo match is a pre-check, not confirmation of an infestation. If the result looks like a bed bug, take clearer photos and continue in the Bug Identifier app for a closer look, then arrange a professional pest inspection to confirm and treat the problem. For bites or skin reactions, see a medical professional — this tool does not give medical advice.

Frequently Asked Questions
Is this a bed bug?
Upload a close-up photo and the tool compares it against bed bug traits — a flat, reddish-brown, apple-seed-shaped body with six legs — and flags lookalikes like fleas and carpet beetles. Use it as a pre-check, then confirm with a professional.
Can a photo confirm a bed bug infestation?
No. A photo can suggest whether a single bug matches bed bug traits, but it cannot confirm an infestation or rule one out. Only a professional inspection can do that, especially since bed bugs hide in seams, cracks, and furniture.
What is often mistaken for a bed bug?
Fleas, carpet beetles, bat bugs, booklice, spider beetles, and young cockroaches are the most common lookalikes. They differ in size, shape, or color, but a blurry photo can hide those clues. The tool points out which ones to compare against your bug.
I think I have bed bugs. What should I do?
Use the tool as a first check, then contact a licensed pest-control professional for an inspection, since bed bugs are hard to eliminate on your own. If you have bites or a skin reaction, see a doctor — this tool does not give medical advice.
How do I photograph such a small bug?
Get as close as your camera can focus without blurring, use bright light, and set the bug on a plain, light surface with a coin or pen tip nearby for scale. A sharp, well-lit close-up gives the tool the most to work with.
