Little blood sucking insect, causing allergic reaction in my boyfriend
Hello,
My boyfriend repeatedly got bitten/stung by an insect, causing rather bad rashes (he's also allergic to a lot of insect bites though). We do have rats (pets, not an infestation) and just found this louse (?) on his desk chair.
He also got bitten two weeks ago, he insecticed the entire apartment (he thought it might be bedbugs but hadn't seen anything), and then was gone for two weeks. Return yesterday night, new bites yesterday evening and today.
I have been bite-free so far. If you have any ideas what it could be, that would help us tremendously in trying to get rid of it.
So far, we're starting to wash everything in contact on 60°C and steam things.
Thanks a lot!
