Is this a flea beetle and do they bite humans?
Please, do flea beetles or their larva bite humans??? I have some in my bedroom. They seem to be coming in thru the window screen. I wake with a few bites around my ankles, I've checked my dogs..no fleas and took some macro photos of these bugs, they really do look like black beetles, 2 mm long. I've also checked for bed bug signs and that is negative. So, can you get a bite from a flea beetle or it's larvae? Thank you.

Flea beetles are so small I don't know what they look like but they don't bite people, they're veg eaters.
Do you spend a lot of time outside? I often get bitten by unknown somethings in the garden but the itchy effects don't develop til the next day, so it would be easy to think they happened at night.
Mozzies are good night time biters though

I used to find that bites around my ankles were usually from cat fleas in the carpet - they'll live there for years and wake up and bite you when the weather warms up

That's not a flea beetle they are tiny round things which eat brassicas they have long hind legs which allows them to jump like a flea.
