We Make Your Opossum Problem Go Away! Ethically, of course.

The opossum (Didelphis virginiana) is the only native North American marsupial. Marsupials are distinguished by their abdominal pouch used for carrying their young.

An opossum is about the size of a house cat, has coarse grayish fur, a pointed face, and hairless, rounded ears. With its long hairless prehensile tail, the opossum can carry things such as nesting materials and even hang upside down from a tree branch.

Opossums are about 2 to 3 feet long, including the tail, and weigh up to 15 pounds, although most fall within the 4 to 7-pound range. Males are usually larger than females. Their feet resemble small hands with five widely spread fingers. All of the toes have a claw except for the opposable thumb on the rear foot. Opossums are well adapted for climbing. The opposable toe on the hind foot assists in holding on to small branches or similar structures.

BEHAVIOR

While their natural habitats are diverse, ranging from arid to moist and wooded to open fields, opossums prefer environments near streams or wetlands. They take shelter in abandoned burrows of other animals, in tree cavities and brush piles, and beneath other dense covers.

In urban and suburban settings they may den under steps, porches, decks, garden tool sheds, and if accessible, in attics, garages, and beneath houses, where they make an untidy nest of sticks and whatever else may be available. The nest components appear piled together rather than woven or stacked. They have complex but flexible social relationships, with overlapping home ranges that allow high populations to develop when food is plentiful.

In its foraging, the nocturnal opossum is a true omnivore, feeding on fruits, nuts, green plants, insects, snails, snakes, frogs, birds and their eggs, and small mammals such as meadow voles, mice, and rats. It eats both fresh meat and carrion and is often seen feeding on road kills, a habit that makes it vulnerable to also being killed.

Opossums that live near people may visit vegetable gardens, compost piles, garbage cans, or food dishes intended for dogs or cats. Having lost much of their natural fear of people, they will even enter a home through a pet door in search of food. Fortunately, they are not aggressive unless cornered, when they may hiss, growl, and show their teeth.

There are typically two mating seasons for opossums in January through February, and June through July. The resultant two litters yield an average of about 7 young each. After a short 13-day gestation period, the tiny, hairless young are born. Like other marsupials, the blind, helpless young find their way into the mother’s pouch where they each attach to one of the 13 teats. No bigger than one-half inch and weighing less than 0.13 gram, they do not let go for about 8 weeks, during which time they continue their development and growth.

At approximately 11 weeks of age, they can leave the pouch for short periods. When the young become too large for all of them to fit inside the pouch at one time, some will ride along by hanging on to the mother’s back.

The young are weaned at about 14 weeks, at which time they are about 9 inches long, not including the tail. Females mate again after the first litter of the season is able to live on their own. The second litter will be sufficiently grown to leave the mother by fall. Mortality in the young is high; most will perish before they are a year old. Those that survive will breed the following spring. Few opossums live beyond 3 years.

Opossums have a top running speed of only 7 miles per hour, so they have developed strategies to escape enemies. They readily enter burrows and climb trees in an attempt to elude danger. When threatened, an opossum may bare its teeth, growl, hiss, and exude a repulsive, smelly, greenish musk like fluid from its anal glands, which offers some degree of protection from predators.

“Playing possum” is another characteristic reaction; the animal rolls over on its side, becomes limp, shuts its eyes, and lets its tongue hang from an open mouth. The heartbeat slows and the animal appears to be dead. This is a nervous shock reaction, but the opossum recovers quickly and takes the first opportunity to escape. When surprised during daylight, opossums appear bewildered and sluggish.

DAMAGE

Opossums are considered a nuisance in gardens and near homes where they feed on berries, grapes, tree fruits and nuts, and defecate on garden paths and patios. They get into fights with dogs and cats and can inflict serious injury with their mouthful of sharp pointed teeth.

Opossums carry diseases such as leptospirosis, tuberculosis, relapsing fever, tularemia, spotted fever, toxoplasmosis, coccidiosis, trichomoniasis, and Chagas disease. They may also be infested with fleas, ticks, mites, and lice. Opossums are hosts for cat and dog fleas, especially in urban environments. This flea infestation on opossums is particularly concerning for transmission of flea-borne typhus, which is increasing in prevalence in Orange and Los Angeles Counties.

Detection

Because they are only active at night and low-light hours, opossums might never be seen as they travel through neighborhoods or yards. Barking dogs and disappearing pet food left out overnight may be the first apparent clues.

Sometimes strange-looking droppings (scat) may be found on garden paths, walkways, and patios, though typically opossums defecate in protected and leafy areas. The scat is difficult to describe as the omnivorous eating habits of the animal preclude an average size, shape, or texture.

Since opossums are messy feeders, you may find remnants of the previous night’s foraging and feeding. An occasional visit by an opossum or a family of opossums may not present cause for concern unless you have pets that remain outdoors at night. Pet and opossum confrontations are relatively common and the pets are often injured. Early action may be warranted to avoid such problems.

Habitat Modification

The aim of habitat modification is to make your premises less appealing to the opossum. Cut back overgrown shrubbery and trim back trees that overhang rooftops at least 5 feet from the roof edge. Continually remove any fallen fruit, which will be readily fed upon by opossums.

Be sure firewood is stacked tightly, leaving no major gaps suitable for a den. Store scrap lumber and other items in an orderly manner, preferably about 18 inches off the ground. Ensure garbage cans have tight-fitting lids and do not place food items or table scraps in your compost bin. Pet food placed outdoors should be removed by nightfall. This will substantially reduce or eliminate the potentially negative interactions between pets and opossums.

Opossum Exclusion Techniques

As with skunks and raccoons, the best solution to an opossum’s presence beneath stairs, porches, decks, or buildings is to screen or block access to the area. Close off all potential entrances or openings under the house, garden tool shed mobile home, deck, etc.

Normally opossums live alone except when with young and then since the young remain in the pouch, they leave with the mother.
