PLEASE HELP!! We are beginning a home remodel, re-gutting project on my grandparents homestead. The house has not been lived in for 10-15 years. It has been invaded with raccoons and they have left evidence of their existence inside the house. How do we safely clean-up the raccoon feces. I am a nurse and I know that there can be health risks involved if not done properly. Does anyone have any experience with this type of problem. We would like to begin renovations, but need to clean the house out first. Please advise.
