This is an apartment bldg. Itchy bites a few months ago caused suspicion of bedbugs. Two weeks ago bedbugs were found on the mattress. The landlord acknowledged the problem being reported at multiple units in this bldg. The landlord called in exterminators who came and sprayed on 8/20/10. Did it work? THAT REMAINS TO BE SEEN.
