For the past two nights I’ve woken up with itchy red bites all over me- just random ones on various limbs etc. I don’t think it’s bed bugs as they’re not in a trail. Just the odd red bump which is very itchy and gets worse with scratching. Since it happens at night, any idea what it could be? I’ve washed all my bedding. Could a random mosquito do all this damage? Also if I’m mostly under the covers?!
