I have been getting insect bites since the last 4 weeks. I usually discover them in the morning do it seems like something in my bed. However, I have searched, cleaned, washed the blankets and linens but it still hasn't gone. I have never spotted any insect either. I am unable to identify what it could be. Bites come everywhere on the body- thighs, arms, stomach, back. Never on the neck or the face though. Attached a photo of a bite. A few bites were big enough to leave marks as they cured.
