How to Prevent Possums From Coming Back

Dealing with a possum problem can be a challenging task, but preventing their return is equally important. Once you’ve successfully removed possums from your property, taking proactive measures to discourage their re entry is key. In this blog post, we’ll discuss practical strategies to prevent possums from coming back, ensuring a possum-free environment. Let’s get started!

Seal Entry Points

Possums are excellent climbers and can squeeze through small openings. To keep them out, conduct a thorough inspection of your home and seal any potential entry points. Focus on the following areas:

a) Attic and Roof: Patch up any holes, gaps, or cracks in the roof, eaves, and vents. Secure loose shingles or tiles and install wire mesh over vents to prevent possums from gaining access.

b) Foundations and Crawl Spaces: Inspect your foundation for cracks or openings and seal them with durable materials like caulk or steel mesh. Install tight-fitting covers on crawl space entrances.

c) Doors and Windows: Ensure that all doors and windows are properly fitted and close tightly. Install weather stripping or door sweeps to eliminate gaps.

Trim Trees and Vegetation

Possums are skilled climbers, using trees and overhanging branches as highways to access your property. Here is how you can stop their entry in your home:-

a) Trim Branches: Trim tree branches that extend close to your home, keeping them at least 6 to 8 feet away from rooftops, fences, and utility lines. This makes it harder for possums to jump onto your property.

b) Remove Vines and Shrubs: Remove dense vegetation, vines, and shrubs that provide easy hiding spots or potential pathways for possums. Maintain a tidy and well-manicured garden to discourage their presence.

Secure Garbage and Food Sources

Possums are attracted to easily accessible food sources. By securing your trash and eliminating tempting food options, you can reduce their attraction to your property:

a) Use Animal-Proof Bins: Invest in sturdy, animal-proof trash cans with tight-fitting lids. Ensure the lids are securely closed, and avoid leaving trash bags outside overnight.

b) Clean Up Fallen Fruits and Bird Feeders: Possums are opportunistic feeders. Remove fallen fruits, nuts, or berries from your garden promptly. If you have bird feeders, consider installing baffles or raising them to a height that possums cannot reach.

c) Store Pet Food Indoors: Avoid leaving pet food outdoors overnight. Store it in secure containers indoors to prevent attracting possums and other wildlife.

Install Motion-Activated Lights and Sound Devices

Possums are nocturnal creatures and are generally averse to bright lights and loud sounds. By installing motion-activated lights and sound devices, you can create a deterrent effect:

a) Lighting: Install motion-activated lights around your property, especially near potential entry points. The sudden illumination can startle possums and discourage their approach.

b) Ultrasonic Devices: Consider using ultrasonic devices that emit high-frequency sounds that are unpleasant to possums. Place them strategically in areas where possum activity has been observed.

Maintain a Clean and Tidy Yard

A well-maintained yard not only enhances the aesthetics but also discourages possums from taking up residence. Follow these tips:

a) Remove Clutter: Clear away piles of debris, unused equipment, or stacked firewood that may serve as shelter for possums.

b) Regularly Mow the Lawn: Keep your lawn well-trimmed and free of tall grass and overgrown vegetation, as they can provide hiding spots for possums.

c) Fencing: Install sturdy fencing around your property to create a physical barrier. Ensure the fence is buried underground to prevent possums from burrowing underneath.

Secure Food Sources

Possums are opportunistic eaters and will gladly take advantage of easily accessible food. 

a) Avoid leaving pet food or trash outside overnight, as it serves as an open invitation for a possum feast.

b) If you have fruit-bearing plants, ensure that any fallen crops are promptly picked up from the ground. By eliminating these food sources, you make your property less appealing to possums.


Preventing possums from coming back requires a combination of proactive measures and ongoing maintenance. By sealing entry points, trimming trees, securing food sources, installing deterrents, and maintaining a clean yard, you can significantly reduce the chances of a possum reinfestation.

Remember, consistency is the key in maintaining a possum-free environment. Stay vigilant and implement these preventive strategies to enjoy a pest-free home and garden.
