Robinson’s Mouse Opossums are primarily nocturnal, meaning they are most active during the night. They are excellent climbers and spend a significant amount of time in trees, foraging for food. These opossums are omnivorous, feeding on a varied diet that includes fruits, insects, small vertebrates, and plant matter. They are solitary animals and mark their territories using scent glands.

Extermination Techniques

  1. Exclusion: Seal off any potential entry points to your property, such as gaps in fences, crawl spaces, and attics. Use sturdy materials like wire mesh to cover openings and prevent opossums from accessing your home or garden.
  2. Secure food sources: Opossums are attracted to easily accessible food. Secure trash cans with tight-fitting lids, remove fallen fruits from the ground, and avoid leaving pet food outside overnight.
  3. Habitat modification: Keep your yard clean and tidy, removing brush piles, stacked firewood, and other potential hiding places that may attract opossums.
  4. Repellents: Use natural repellents, such as ammonia-soaked rags or predator urine, near areas where opossums are causing problems. This may deter them from frequenting those areas.
  5. Motion-activated deterrents: Install motion-activated lights, sprinklers, or noise devices near areas where opossums are causing issues. The sudden activation of these deterrents can startle and discourage them from returning.
  6. Seek professional assistance: If opossums become a persistent problem and none of the above methods are effective, it is recommended to contact a licensed wildlife control company experienced in humane removal. We provide appropriate advice and assistance tailored to your specific situation.
