We have white flys in our house in mainly the upstairs
Since we moved in I've been getting bites and wondered if it could be them
The bites look like mosquito bites .
I moved my bed today and they were flying around from the mattress?

The whiteflies I'm familiar with are a plant feeder, so the odds are highly against them biting you. You may have another pest along with the "flies." I can't begin to guess what that might be, there are too many options.

This is a picture of the actual "Whitefly." Do yours look similar?
