Why Are There So Many Possums Around My House? A Deep Dive

Possums are drawn to your property by readily available food sources, shelter, and a safe environment to raise their young. This article explains why you’re seeing so many possums around your house and offers practical advice on how to manage their presence humanely.

Understanding the Possum Phenomenon

Encountering one possum near your home might be a fleeting occurrence, but persistent sightings suggest a more established presence. Why are there so many possums around my house? The answer usually boils down to three key factors: resource availability, habitat suitability, and lack of deterrents.

• Resource Availability: Possums are opportunistic omnivores. They’ll happily feast on:
  • Pet food left outdoors
  • Unsecured garbage
  • Fallen fruit from trees
  • Insects and grubs in your yard
  • Birdseed
• Habitat Suitability: Your property may provide ideal shelter:
  • Hollow trees or logs
  • Under decks or sheds
  • In attics or crawl spaces
  • Brush piles
• Lack of Deterrents: Possums are relatively timid animals. However, they become bolder if they perceive little or no threat. The absence of predators (natural or domestic) and a generally undisturbed environment can encourage their presence.

The Possum Advantage: Adaptability and Survival

Possums are remarkably adaptable creatures. Their ability to thrive in various environments, including urban and suburban areas, contributes to their proliferation.

• Nocturnal Lifestyle: Their nocturnal habits allow them to avoid daytime disturbances and potential predators.
• Opposable Thumbs: They have opposable thumbs on their hind feet, enabling them to climb trees and access hard-to-reach food sources.
• Prehensile Tail: Their prehensile tail acts like a fifth limb, providing stability and support when climbing.
• Dietary Flexibility: They eat almost anything, making them less reliant on specific food sources.

Identifying Possum Activity

Recognizing signs of possum activity is crucial for addressing the issue effectively. Look for these telltale signs:

• Tracks: Possum tracks have five toes on both front and hind feet, with the hind footprint showing a thumb-like digit at a wide angle.
• Droppings: Possum droppings are similar to dog feces but often contain undigested seeds or berries.
• Damage to Gardens: They may dig up plants or eat fruits and vegetables.
• Nocturnal Noises: Rustling, scratching, or hissing sounds at night can indicate possum activity.
• Physical Sightings: Actually seeing possums roaming around your property is, of course, a clear indication.

Humane Possum Management Strategies

Effective possum management prioritizes humane and ethical approaches.

• Eliminate Food Sources:
  • Secure garbage cans with tight-fitting lids.
  • Bring pet food indoors at night.
  • Clean up fallen fruit and birdseed regularly.
  • Consider using motion-activated sprinklers to deter them from gardens.
• Restrict Access to Shelter:
  • Seal openings under decks and sheds.
  • Trim tree branches that overhang your house.
  • Clear brush piles and debris.
  • Ensure your attic and crawl spaces are properly sealed.
• Use Deterrents:
  • Motion-activated lights can startle them.
  • Ultrasonic pest repellers may provide limited effectiveness.
  • Sprinkling cayenne pepper around vulnerable plants might deter them (use cautiously, especially with pets).
• Live Trapping (as a Last Resort): If other methods fail, live trapping can be an option, but it’s crucial to check local regulations regarding relocation. Captured possums should be released in a suitable habitat at least 5 miles away from your property. Relocation should only be considered if you are prepared to take ALL of the other actions outlined above.

Comparing Possum Management Techniques

The Importance of Coexistence

While it’s understandable to want to minimize possum activity around your house, it’s important to remember that they play a role in the ecosystem. They consume insects, rodents, and carrion, contributing to natural pest control and decomposition. The question becomes not how to eliminate them, but how to manage their presence responsibly.

Frequently Asked Questions About Possums

Why are there so many possums around my house specifically during certain times of the year?

Possum activity often peaks during the spring and fall. In the spring, it’s due to breeding season, with females actively seeking resources to support their young. In the fall, possums are preparing for winter by accumulating fat reserves, leading them to forage more aggressively. Understanding these seasonal fluctuations can help you anticipate and prepare for increased possum presence.

Are possums dangerous to humans or pets?

Possums are generally not aggressive towards humans or pets, but they can bite or scratch if they feel threatened. They are more likely to play dead (hence the term “playing possum”) than to attack. However, they can carry diseases like leptospirosis and parasites like fleas and ticks, so it’s important to avoid direct contact and maintain a safe distance.

What diseases can possums carry, and how can I protect myself?

While possums are relatively disease-resistant, they can carry diseases such as leptospirosis, tuberculosis, and coccidiosis. They can also transmit parasites like fleas, ticks, and mites. To protect yourself, avoid direct contact with possums or their droppings. Wear gloves when cleaning up areas where possums have been and wash your hands thoroughly afterward. Keep pets up-to-date on their vaccinations and parasite prevention treatments.

Will possums damage my garden?

Yes, possums can damage gardens by eating fruits, vegetables, and flowers. They may also dig up plants in search of insects. To protect your garden, consider using fencing, netting, or motion-activated sprinklers. You can also try planting possum-resistant plants.

How can I tell the difference between a possum and a rat in my attic?

Possums are much larger than rats, typically measuring 2-3 feet in length, including their tail. Rats are much smaller, usually less than a foot long. Possums also make distinctive noises – scratching, hissing, and growling – while rats tend to be quieter and make more scurrying sounds. Look for their distinctive droppings as well.

Are possums protected by law?

Possum protection laws vary by state and locality. In some areas, it may be illegal to trap or harm possums without a permit. Always check local regulations before taking any action to remove or control possums on your property.

What should I do if I find a baby possum?

If you find a baby possum that appears orphaned or injured, contact a local wildlife rehabilitator or animal control agency immediately. Do not attempt to care for the possum yourself, as they require specialized care and handling.

Can I deter possums with specific plants?

While no plant is completely possum-proof, some are less attractive to them. These include plants with strong scents, prickly foliage, or toxic properties. Some examples include: mint, lavender, rosemary, and thorny shrubs. Combining these with other deterrents can be more effective.

Is it safe to trap and relocate possums myself?

While legal in some areas, relocating possums can be harmful to both the individual animal and the ecosystem. Possums have established territories, and relocating them can disrupt their social structure and ability to find food and shelter. Furthermore, they may not survive in a new environment, and they can spread diseases to other wildlife. Consider non-lethal deterrents first.

Do possums hibernate?

Possums do not hibernate in the traditional sense. They may become less active during extremely cold weather and seek shelter, but they do not enter a state of prolonged dormancy. They continue to forage for food throughout the winter, which is Why are there so many possums around my house? even during colder months.

What’s the best way to clean up possum droppings?

Wear gloves and a mask when cleaning up possum droppings to protect yourself from potential diseases and parasites. Use a disinfectant solution to thoroughly clean the affected area and dispose of the droppings in a sealed bag. Wash your hands thoroughly after cleaning.

Will a dog deter possums?

A dog can deter possums from your property, but it’s not always a guarantee. Some possums may become accustomed to the presence of a dog and continue to visit your yard. It also depends on the dog’s temperament and prey drive. Supervise your dog when it’s outside, especially at night, to prevent any altercations with possums.
