7 Ways to Get Rid of Possums Under Your House

Opossums are very good at surviving, they are omnivores and will eat just about anything. They adapt quickly to a new environment, so you can expect them to find a home under your house in no time. They get into your trash cans and make a mess of your lawn. They may even have settled in your attic or under your patio.


If you have possums in your backyard, you need to take serious steps to get rid of them. In fact, getting rid of opossums is not as easy as it sounds.

If you notice possums living under the house or deck, you want to make sure there aren’t any babies. If there are babies, wait about a month for the babies to go out on their own before catching or repelling adult possums.

Once the babies are gone or if there were no babies, you can start with one of these 10 ways to get rid of the possums under the house

7 Ways to Get Rid of Opossums Under the House

Opossums are excellent climbers. They will climb into your house from trees and other structures. If you have possums under your home, it is important to remove them before they damage the structure of your home. Opossums can cause damage to insulation and electrical wires if left unchecked.

There are several ways to get rid of possums under the house. Some are more successful than others.

1. Check for holes in the foundation

The first thing to do when trying to get rid of possums under your home is to check for holes in the foundation. Make sure there are no cracks or holes in the foundation that would allow a possum to enter your home. If you find one, fill them in ASAP to keep opossums out.

2. Remove debris around the foundation

Opossums often make their homes under houses by making nests from leaves, sticks and other debris you may have around the foundation of your house. Remove all debris around the house so they have no place to hide or live. This makes it harder for them to get under your house.

3. Block access roads

Prevent them from entering the house by closing off any entrances with wire mesh screens or metal sheaths. Make sure there are no holes or gaps for them to pass through.

Find a den under your house.

Opossums usually dig their burrows under a building or structure raised from the ground. Often the burrow is in an area where the soil is soft enough to dig in, such as a mulch bed or compost pile.

Mark the location of the den with stakes and rope.

Once you’ve found where the possum’s burrow is, use sticks and string to mark off the area so you can easily find it later when you come back with supplies to close off the entrance hole.

Block the entrance hole to the possum’s burrow using wire mesh fencing or hardware cloth.

Use wire mesh or hardware to cover the entrance hole to prevent possums from entering or exiting their burrows under your home or other structure.

4. Install a Live Possum Trap

The most effective way to get rid of possums under a house or patio is to purchase a live trap cage. These traps are specially made for catching animals such as possums and raccoons.

This is an effective way to get rid of possums that have roamed your property without injuring them or using inhumane methods. Be sure to check with your local government before using live traps so you know the regulations in your area.

They work by enticing the animal inside with food or fruit and once it enters the trap, it activates a door that closes behind it. Once this happens, all you need to do is pick up the trap (with the animal in it) and transport it at least 5 to 10 miles away from your home so they don’t come right back home.

5. Eliminate Food Sources

If you remove the food sources for possums, they will go away on their own. Throw out all pet food that is left outside at night, bring all bird feeders inside, and store your waste in sealed bins instead of sidewalk bags.

Until the possums realize there’s nothing left for them here, it’s hard to get them off your property permanently.

6. Scare Them

Install motion sensor lights and sprinklers to scare them away if they come near your house at night.

Motion sensors are a great way to make sure you have all bases covered when it comes to keeping possums out of your property. It can be difficult to determine where they come in and out, but motion sensors can help you pinpoint the exact spot.

Motion sensors can detect things like heat and movement. Once they sense change, they will set off lights or set off alarms. This deters possums so much that they leave your property and never come back.

7. Use a repellent

Spray a predatory odor repellent around the perimeter of your home to keep them from getting close. Examples of repellents include wolf urine and ammonia-soaked rags.

  • Place ammonia-soaked rags in the area where you’ve seen possums enter your home’s crawl space. Replace the rags every few days. Opossums do not like the smell of ammonia and will stay away.
  • Mix 1 tbsp. of castor oil and 1 tsp. of liquid dish soap with 1 gallon of water in a bucket to create an all-round repellent for possums and other small animals. Spray this solution around areas where possums have entered your homes, such as vents, windows and foundations. Reapply after heavy rainfall.
  • Combine dry red pepper flakes with water in a spray bottle and spray it around areas where you’ve seen possums enter your home or around their burrows outside when they’re digging up your yard or yard.
  • Spray peppermint oil around the house on walls, windowsills and any other area where possums can invade. Opossums do not like the smell of peppermint oil and will therefore avoid this area.
  • Sprinkle tea tree oil around any area where you think a possum is entering your home. Tea tree oil is also not pleasant for possums, so they will stay away from it if possible.

In summary, Possums are a relatively common pest in both urban and rural areas. They may look cute, but they can be quite a nuisance if they move under your house or in the attic.

If you have possums under your home, it is important to remove them as soon as possible. The longer they stay, the worse the damage will be.
