How Do I Get Rid of Opossums? The best way is physical trapping and removal.
OPOSSUM BIOLOGY: (Didelphis virginiana) Possums look somewhat like giant rats, with their pointed snouts and skinny, naked tails. They are in fact North America's only marsupial (like kangaroos, they raise their young in a pouch). Adults average 10-14 lbs. They don't live very long, rarely more than two years, three max. They mate in January, and then the tiny young climb into the pouch and grow, then cling to the mother's back, then drop off and lead a life on their own. Opossums are omnivores, which mean that they eat anything. They are nocturnal. They have the most teeth of any mammal (50), a prehensile tail, opposable thumbs, the male has a bifurcated penis, and they have incredible immune systems.
OPOSSUM BEHAVIOR: Possums are nomadic and opportunistic animals. They sometimes establish a home base, especially a female with young, and often live in human structures. They rummage around at night for food, and will eat pretty much anything, but prefer meat, and even rotting carcasses. They are not very fast, and will stand their ground when threatened, bearing their 50 sharp teeth. In dire circumstances, they will sometimes feign death, or "play possum" - they fall over, tongue hanging out, etc.
NUISANCE CONCERNS: Because they are opportunistic scavengers, they can come into conflict with people and cause various problems. They'll steal garbage, pet food, etc. They can distress pets, and if a dog corners one, it can get a nasty bite. They can spread fleas and other parasites. Most of all, they often like to live in human structures, such as under sheds or decks . They can also cause destruction in houses and attics.
