not bedbugs, I'm certain. But what is it?!

hm, so I remember ages ago I was bitten by a mosquito lots on my feet, since then I've had these red blotchy bites. They don't itch at all. Some of the skin is peeling and scabbing. I also have these bites on my fingers.
I am positive it is not bedbugs because my dad is a clean freak and vacuums my bed once a week, changes and washes my sheets once a week and we always check the mattress to find no bugs hiding in crevices what so ever.
I am baffled.
also, 3 years ago I had scabies, I know it is not that because I only have bites on my feet + I remember the experience of scabies, this is nothing like that. It doesn't itch plus they're not the same bite.
Allergic reaction do you think?

PLEASE HELP ME :(
