Hoarding collecting, clutter, junk, trash or just way to much stuff. The problem with this is often the amount collected. To much often hides other issues like cockroaches and rodents. With filth comes secondary pest infestation, after cockroaches and rodents may come parasites and flies. If you know me at all, flies are the biggest yuck factor.
This disease is known as compulsive hoarding by excessive acquisition (collecting). And an inability or unwillingness to discard large quantities of objects that cover the living areas of the home and cause significant distress or impairment. I’ve only had to deal with once so far, a mobile home packed to the gills and impossible to actually get under control without a significant clean-up.
