Well, this was a fun task. I had a Real Estate agent call me saying that one of their homes on the market had a family of rats nesting in the barbecue. To my surprise, she was right as you could see in the video. I ended up sealing all of the entry points with expansion foam and steel whool to exclude these nasty rats from re-entering for some free rent.
Rats carry many diseases such as Hantavirus, Typhus, Salmonella, and Rat Bite Fever. It is important to sanitize and clean any areas where they have been nesting because if you contact or are around rodent activity, you could be in for a surprise.
