Alston's Woolly Mouse Opossum


Alston’s Woolly Mouse Opossum (Micoureus alstoni) is a small marsupial found in the tropical rainforests of Central and South America. It is characterized by its soft, dense, and woolly fur, which provides insulation and camouflages it among the dense foliage. With its large eyes and rounded ears, this opossum has adapted to its nocturnal lifestyle.

Habitat and Behavior

Alston’s Woolly Mouse Opossums inhabit the forested regions of Central and South America, including the Amazon rainforest. They are primarily arboreal, spending much of their time in trees and using their prehensile tails for balance and navigation. These opossums are solitary and nocturnal, emerging at night to search for food, which consists of insects, fruit, nectar, and small vertebrates.


Alston’s Woolly Mouse Opossums have an omnivorous diet, feeding on a variety of food sources available in their habitat. They primarily consume insects, such as beetles, ants, and termites, as well as fruits, nectar, small vertebrates, and plant matter. Their diet plays a vital role in the ecological balance of their environment.


The reproductive cycle of Alston’s Woolly Mouse Opossums is similar to other marsupials. Females have a well-developed pouch where they nurture their young, called joeys. After a gestation period of approximately 15 days, the underdeveloped joeys are born and crawl into the mother’s pouch, where they continue their development. They remain in the pouch for several months until they are ready to venture out and explore their surroundings.

Effective Opossum Control Methods

If you’re experiencing an Alston’s Woolly Mouse Opossum infestation and require assistance, employing effective control methods is crucial. Here are some common techniques for opossum control:

  1. Exclusion: Seal off any potential entry points, such as gaps in buildings or fences, to prevent opossums from accessing your property.
  2. Habitat Modification: Remove food sources, such as fallen fruits or bird feeders, and eliminate potential nesting areas like woodpiles or debris.
  3. Trapping and Removal: In situations where opossums pose a persistent problem, professional trapping and removal services can safely relocate them away from your property.


Alston’s Woolly Mouse Opossums are generally not harmful to humans or pets. They are small, shy creatures that prefer to avoid confrontation. However, like any wild animal, they may defend themselves if they feel threatened. It’s important to maintain a safe distance and avoid direct contact to minimize any potential risks. If you have concerns about Alston’s Woolly Mouse Opossums on your property, it’s advisable to seek professional wildlife removal assistance for appropriate management and control measures.
