Hi,
I really related to your story. I realize it's almost 2 years old and I'm wondering if you solved your problem or found out anything else. I am scheduled to have Terminix come out tomorrow to spray inside and outside our home. I'm praying that this will help me stop this nightmare I am now going through. I also am the only one in the home being affected by this unsolved mystery. I ordered a digital microscope last night from Amazon that someone on here referred me to. I've been wearing a 5 x's magnifying glass around my neck for a couple of months now (I kept losing it so I took a shoe string and tied it so I never lose it again) lol
I sure hope you solved your problem and also hope that you see this message and reply to me.
