Bed bugs!!

I AM GOING CRAZY. A "friend" of mine let me sleep in her floor for a night. Forgetting to mention she had them. I itched all night long, not knowing.

Come home, guess what we brought with us. This has been almost 7 months ago. Im STILL trying to pinpoint and kill em. I look crazy cause ive taped every seam in the room. I cant sleep. Ive read they cause illnesses.

I cant pay $80 to $150 for exterminaters. Does ANYONE have any home remedies that worked or know something i can try?
