I recently discovered that the attic of the house I moved into last December has apparently been home of hundreds of bats. I discovered them because of a smell that slowly permeated the house to the point that, at its peak, I could barely take a breath in the house. I have been forced to stay in a hotel the last two weeks while my landlord had lights installed in the attic, the guano bagged and removed, and the insulation removed. He also installed spotlights in the yard. Most of the bats appeared to have moved on after the lights were installed; however, there were a few that lingered. As of 4 days ago I was assured all my "roommates" had moved out so I moved back in last night. Last night the house was relatively free of odor - just a little lingering in the sun room where the attic crawl space is- but today I walked in and the smell hit me like a brick! It seems to be building to another crescendo. I am assuming that means that my roommates have returned. My question is this: how does one cope with and/or eradicate the odor of a bat infestation. To tell the truth, I have done so much research that I have gotten over any fear of the bats, but I can't live with the smell.
