To be kind, opossums are interesting-looking animals. Some would even say that they're downright funny-looking. In fact, 'possums have been described as looking like they were put together from "God's spare parts."
Opossums are medium-sized mammals with thick fur that can make them look bigger than they are, with jaws resembling those of a dog, prehensile tails that looks like those of rats, and human-like "hands" and rear feet with opposable thumbs. They're usually white in color (in fact, the word "opossum" is derived from an Algonquian word meaning "white dog," although some are more gray or tan.
Most uniquely among North American mammals, opossums are marsupials, which means that their females have pouches in which they rear their young immediately after birth. The pouch is called a marsupium, and opossums are the only mammals native to North America that come equipped with one.
Behavior-wise, if we had to sum up the opossum's nature in one word, it would be "adaptable." That's one of the secrets of their success. They don't have very good vision, they age very rapidly, they're not fleet of foot, and they're not especially well-equipped to fight. But they are adaptable enough to make the best of a wide variety of situations and to live comfortably in all kinds of settings.
For example, opossums are tree-dwellers by nature, but they're also happy living in the ground. Occasionally they'll even move into burrows abandoned by other animals. They'll also happily move into crawl spaces, sheds, garages, attics, soffits, and even old cars. We've even found them living in wall and ceiling voids. They're very easy to please that way. They'll move into any available space without complaint as long as it's rent-free.
The opossum's diet is also flexible, which is to say that they'll eat pretty much anything. In nature they're omnivores, and they've adapted well to living around humans. They'll eat human garbage, table scraps from picnic areas, pet food, and pretty much anything else they can find that's edible.
Opossums also have very high resistance to most diseases, which is something that scientists have been studying for many years. They very rarely get sick. Nonetheless, they do age very quickly and have very short life spans -- usually two years at most in the wild.
Probably the most famous fact about possums is their academy award-worthy skill at "playing dead" when they are attacked or threatened. This doesn't seem to be entirely voluntary on the possum's part. It seems to be something more along the lines of fainting and not quite within their control. But it serves an important survival purpose for them.
What happens is that once the possum has tried the usual animal methods of resisting an attack -- snarling, baring their teeth, snapping, and so forth -- they'll fall into a state that makes them look and smell dead. They stop moving and lay there, motionless, mouths frozen in a snarl; and they start secreting a foul-smelling odor that makes them smell like a rotting, dead animal. Because most predators are smart enough not to eat rotting food, the predator animal usually walks away, thinking that the possum is dead.
The most common reason why people dislike opossums is because they find them scary-looking. But like any wild animal, they can also make a serious mess and cause a health hazard if they get inside your home. They carry parasites like fleas, ticks, and so forth, and their urine and droppings can cause odors that travel through your home, especially if you have forced-air heating and cooling. They're also destructive and will often tear away at insulation, HVAC ducts, and store possessions.
Outside the house, opossums can be beneficial because they do consume their share of rodents. But because they've adapted to living on human garbage, they may not hunt as much (or at all) if human leftovers or pet food are available to them. They can also be a nuisance on farms and in gardens because they sometimes eat the crops.
The biggest health threat posed by opossums is actually to horses. Possums have been confirmed to be part of the transmission cycle of Equine Protozoal Myeloencephalitis (EPM), a serious, degenerative neurological disease affecting horses and other equines. So you most certainly don't want opossums anywhere near a stable.
It's also suspected that because of their extremely strong immune systems, opossums may be able to carry the rabies virus for a long time without being affected by it, but transmit it to humans or other animals nonetheless.
Not every opossum-removal job we perform requires exclusion. More so than most other wild animals, opossums often simply walk into garages, basements, and other parts of homes through open doors. When this is the case, all we have to do is remove them for you and release them elsewhere.
Sometimes, however, opossums make their way into your home through structural gaps, holes, or other flaws that require exclusion work -- basically, making your home possum-proof. This also will seal out other animals like raccoons and rats, so it's a good investment in keeping your home animal-free.
Please contact us if you have a problem with opossums or any other nuisance animals. We hope to hear from you soon.
