Linnaeus’s Mouse Opossum: A Comprehensive Guide to Identification and Extermination

Linnaeus’s Mouse Opossum, scientifically known as Marmosa murina, is a species of opossum found in specific regions. Here is some essential information about this particular opossum:


Linnaeus’s Mouse Opossum is a small marsupial with a body length ranging from 3 to 4.5 inches and a tail length of approximately 3.5 to 4.5 inches. They have dense fur, which is usually gray or brown in color, helping them blend into their natural surroundings. These opossums have a slender body with large eyes and a long, prehensile tail that aids in their arboreal lifestyle.

Linnaeus's Mouse Opossum


Linnaeus’s Mouse Opossum is primarily arboreal, spending a significant amount of time in trees. They are nocturnal creatures, meaning they are most active during the night, and they primarily feed on insects, fruits, and small vertebrates. These opossums have the ability to grasp branches tightly with their prehensile tail, allowing them to move skillfully through the forest canopy.

Extermination Techniques

  1. Habitat Modification: Since opossums are attracted to areas with abundant food sources, you should make your property less appealing. Ensure that trash cans are securely sealed and do not leave pet food or other sources accessible outside. Additionally, reducing clutter and removing potential hiding spots, such as piles of debris or unused structures, can discourage opossums from frequenting your property.
  2. Exclusion: This involves sealing off potential entry points, like gaps in fences or building holes. Use sturdy materials like wire mesh or hardware cloth to block openings while ensuring no opossums are trapped inside.
  3. Repellents: Certain natural repellents or deterrents may help discourage Linnaeus’s Mouse Opossums from entering your property. These can include strong-smelling substances like ammonia-soaked rags or predator urine, creating an unpleasant environment for the opossums. However, the effectiveness of these repellents may vary, and professional advice is recommended.
