Bedbugs and fleas both bite people and both cause itchy marks, so they are often confused. Telling them apart matters, because they live in different places and need different treatment. Spraying a bedroom for bedbugs will not solve a flea problem that is coming from a pet or the compound — and the reverse is also true.
How they look and move
Bedbugs are flat and oval when seen from above, like a lentil, reddish-brown, and about 5 mm long as adults. They crawl and never jump.
Fleas are much narrower — flattened from side to side, so they look thin from above — darker brown to black, and usually 1–3 mm long. They have powerful back legs and jump readily. If an insect leaps away when you try to catch it, it is almost certainly a flea.
Where you find them
- Bedbugs live where people sleep or sit for long periods: mattress seams, bed frames, headboards, sofas and nearby cracks. They leave dark spots, shed skins and eggs in these places.
- Fleas are mostly associated with animals — dogs, cats, and sometimes rodents. Their eggs and larvae develop in pet bedding, carpets, rugs and shaded soil in the compound. Adults jump onto people who pass by.
Where the bites appear
Bite patterns are a clue but never proof on their own.
- Bedbug bites tend to be on skin exposed during sleep: arms, shoulders, neck and face. They often appear in a line or small cluster.
- Flea bites are most often on the lower legs and ankles, because fleas jump up from the floor. They are commonly small, very itchy spots.
Some people react strongly to bites and some not at all, and other insects and skin conditions cause similar marks. Physical evidence is what confirms the cause.
Other insects that get confused with bedbugs
- Carpet beetle larvae — small, hairy and slow; they damage fabrics but do not bite.
- Cockroach nymphs — longer, with long antennae, and much faster runners.
- Bat bugs and bird bugs — close relatives of bedbugs that come from roosting bats or nesting birds and occasionally bite people. They need a professional to tell apart.
Why identification changes the treatment
Flea control focuses on pets (with veterinary products), pet bedding, floors and outdoor resting areas. Bedbug control focuses on sleeping and resting areas, furniture and cracks, and is planned across more than one visit because of their egg stage — see our two-treatment programme.
If you are unsure what is biting you, collect a specimen on clear sticky tape if you can, photograph any evidence, and book a bedbug inspection. For fleas and other pests, our parent company Pestraid Kenya handles general pest control.
