Opossums are unsanitary and could cause negative health effects
They typically leave their feces and urine on the attic insulation and in various places in your home, or office, producing a strong and repulsive smell, and could also cause negative health effects. They can also have as many as 15 surviving young at a time. If the Opossum or one of its young fall into a wall space and can’t get back out, it will die and cause a terrible smell. The smell of a dead carcass can increase when it begins to decompose. The dead animal carcass is also covered in parasites and additional odorous bacteria that really need to be removed.
