artment is always kept very clean and organized so it appears as though they were all gathered in my mattress and box spring. I contacted the building management and arranged for an exterminator the next day. I threw out the contaminated linens and leaned the box spring and mattress against the wall for treatment. After 28 hours of properly preparing my place the exterminator came in and did his treatment. Five hours later I returned to my apartment to put my things away. Not wanting to sleep on that mattress again I slept on my sofa making sure that any leftover bugs could not gain access from the surrounding floor and walls. I have not seen a trace of them for about 9 days but can't get over the paranoia I now have in my own apartment. I clean and vacuum my place constantly and can't figure out where they came from. My guess is that I had them for about 2 months. They must have been biting me because they were leaving dark dots all over my mattress but I can't find any marks on my body.
