I know this is a few years late, but I just wanted to let you know we had a similar situation, but it was for a few months every summer. Turns out there were bats in our attic, and the bat bugs will still bite you like bed bugs except they don’t really love humans so it will be infrequent and you won’t have to worry about an infestation! When you get rid of the bats, they go away eventually.
The biggest problem with these bites is that, depending on the persons skin and their tolerance to bacteria, their appearance is different on different types of people. I have noticed in the past that if I get bitten by a mosquito, I get a rather large red mark (even without scratching), whereas my husbands skin hardly shows any signs of the bite.
I’ve been getting bites as well and I am extremely allergic. It is super itchy and now I have scars that will never go away. I am the ONLY one in my family getting bitten so no one understands my pain. I have 2 hours of sleep max at night because of both paranoia and getting bitten. I am up to the point that I cry almost every night from the pain. I’ve tried a lot of solutions, the one that is currently working for me is Vaseline. I apply several thick layers of the jelly and it stops the pain and itching. It also helped a lot with the swelling. I noticed it sped up the healing process a lot more than over-the-counter drugs that I’ve tried. I hope this helps!
