Do Possums Live Under Houses? Understanding These Nocturnal Neighbors
Yes, possums frequently live under houses. This behavior provides them shelter and easy access to food sources, making under-house locations ideal habitats.
Possums and the Lure of Urban Living
Possums, more correctly known as opossums in North America (though the term “possum” is widely accepted), are adaptable marsupials thriving in diverse environments, including urban and suburban areas. They are opportunistic creatures, always on the lookout for food, water, and, most importantly, safe shelter. Unfortunately, the space under our homes often provides all three. The crawl spaces, voids beneath porches, and areas under decks become attractive real estate for these nocturnal wanderers. Do possums live under houses? Absolutely, and understanding why is key to preventing and managing these cohabitations.
Why Under the House? A Possum’s Perspective
From a possum’s viewpoint, the underside of a house offers several compelling advantages:
- Protection from Predators: Hawks, owls, dogs, and cats are potential threats. The enclosed space under a house provides a refuge from these dangers.
- Stable Temperature: Crawl spaces tend to maintain a more consistent temperature than the outside world, providing relief from extreme heat or cold.
- Nesting Site: Female possums, especially those with young (joeys), seek secure and dry places to build nests. Under houses often fit the bill perfectly.
- Proximity to Food: Possums are omnivores with a varied diet. They readily consume insects, fruits, pet food, garbage, and carrion. Our yards often provide a buffet of these options, making nearby shelter even more appealing.
Identifying a Possum Problem
Knowing how to recognize the signs of a possum infestation is critical for timely intervention. Some common indicators include:
- Unusual Noises: Scratching, rustling, or thumping sounds coming from under the house, particularly at night.
- Droppings: Possum droppings resemble those of a small dog, are dark in color, and typically contain undigested food.
- Strong Odor: A musky or ammonia-like smell emanating from the crawl space.
- Visible Sightings: Spotting a possum entering or exiting the area under the house.
- Disturbed Vegetation: Overturned garbage cans, scattered pet food, or damaged gardens nearby can signal a possum’s presence.
Preventing Possums from Moving In
Preventing possums from taking up residence is always preferable to dealing with an existing infestation. Here are some proactive measures:
- Seal Entry Points: Inspect the perimeter of your house for cracks, holes, or gaps in the foundation, siding, or around pipes. Seal these openings with durable materials like wire mesh, caulk, or sheet metal.
- Secure Garbage Cans: Use garbage cans with tight-fitting lids to prevent possums from accessing food scraps.
- Remove Pet Food: Avoid leaving pet food outdoors, especially overnight.
- Clear Vegetation: Trim overgrown bushes and shrubs around the house to reduce potential hiding places.
- Install Motion-Activated Lights: Possums are nocturnal and tend to avoid brightly lit areas.
- Use Deterrents: Some homeowners find success with repellents containing ingredients like peppermint oil or ammonia. However, their effectiveness can vary.
Dealing with an Existing Possum Infestation
If you suspect that do possums live under houses? and in your house, and all signs point to “yes,” then consider these approaches:
- Professional Removal: Contact a wildlife removal service. They have the expertise and equipment to safely and humanely remove the possum. This is often the best option, especially if you are unsure how to proceed or concerned about your safety.
- One-Way Door: A one-way door allows the possum to exit but prevents it from re-entering. This method is most effective when the possum is known to be living alone and not with young. Ensure all other potential entry points are sealed before installing the one-way door.
- Humane Trapping: If trapping is necessary, use a humane trap baited with fruit or peanut butter. Check the trap frequently and release the possum in a suitable natural habitat well away from your property. Check local laws and regulations before trapping.
Considerations for Possum Welfare
Remember that possums are protected by some wildlife laws, and mistreating them can result in fines. It’s crucial to handle them humanely and avoid causing unnecessary stress or harm. If you find a sick, injured, or orphaned possum, contact a wildlife rehabilitation center for assistance.
Frequently Asked Questions
Are possums dangerous to humans?
Possums are generally not aggressive and will typically avoid confrontation. However, they may bite or scratch if they feel threatened. They can also carry diseases, though transmission to humans is rare. It’s best to avoid direct contact with possums.
Do possums carry rabies?
Possums have a very low body temperature, which makes them highly resistant to rabies. They are far less likely to carry rabies than other wild animals like raccoons, bats, or foxes. However, they can carry other diseases.
What do possums eat?
Possums are omnivores with a broad diet. They eat insects, fruits, vegetables, nuts, carrion, garbage, pet food, and even snakes. They play a role in controlling insect populations.
How long do possums live?
In the wild, possums typically live for 1-2 years. Their lifespan is short due to predation, vehicle collisions, and other environmental hazards.
What is the gestation period for possums?
Possums have a very short gestation period, only about 12-13 days. They give birth to a large litter of tiny, undeveloped young called joeys.
Where do possums typically nest?
Possums are opportunistic nesters and will use a variety of locations, including tree cavities, hollow logs, rock crevices, and, unfortunately, under houses.
When are possums most active?
Possums are primarily nocturnal, meaning they are most active at night.
How can I tell the difference between a possum and a rat in my attic?
The sounds are often different. Possums are larger and their movements sound heavier than rats. Possums may also make growling or hissing noises. You might also find droppings that differ in size. If possible, try to get a visual confirmation.
Is it safe to remove possum droppings myself?
While possum droppings are not considered highly dangerous, it’s best to take precautions. Wear gloves and a mask to avoid inhaling dust particles that may contain bacteria or parasites. Clean the area with a disinfectant solution.
Can I use mothballs to deter possums?
Mothballs are not recommended as a deterrent. They are toxic and can be harmful to pets, children, and the environment.
Will a dog keep possums away?
A dog may deter possums, but it’s not guaranteed. Some possums are bold and may not be afraid of dogs, especially if they are accustomed to their presence.
If I trap a possum, where should I release it?
Release the possum in a natural habitat at least 5-10 miles away from your property. Choose a location with access to food, water, and shelter. Be sure to check local regulations regarding releasing wildlife. If do possums live under houses? In a neighbor’s yard, be mindful of where you choose to release them.
