Nuisance animals cause odor problems in a variety of ways. Their excrement is a primary source of odor problems, and often quite noticeable if an animal has taken up residence somewhere in your home. A colony of bats in the attic, for example, can really stink up the house, as can an opossum, which is a smelly animal that leaves a lot of waste in an attic. Animal carcasses are another source of odor, and if you’ve left out poison to kill rats, you’d better get ready for a big odor problem! Skunks present a whole other dimension in odor problems. I can identify the source of animal odors, and eliminate both the current source of the odor (for example, excrement removal) and the underlying cause (the animal’s entry into your home). This work may be covered by homeowners insurance.
