We're fighting an active BB infestation (received 1st treatment May 2nd) that appears to be contained in our daughter's room. PCO found no evidence of BB's in our bedroom. Our daughter, who is VERY reactive to bites, has not complained of any ever since she started sleeping in our bed with me on April 25th. I thought I had bites (3 non-itchy red dots in a neat row on my hand) but after treatment have not seen anything new on myself, either.
However, I found these dots on my sheets yesterday morning while making the bed. There are four separate dots only on the side where I sleep. They didn't smear when wet (didn't occur to me to test until after taking the pictures) but because I didn't discover them until around 10 AM they might not have been fresh. The mattress was encased after treatment but to be honest I have not checked the bed for cast skins or other evidence yet.
