Scratching, thumping, or rustling overhead at night may mean a Virginia opossum has entered an attic or roof space. In the United States, “possum” usually refers to the opossum, a generally shy, nocturnal marsupial. The safest way to get rid of a possum in the roof is to confirm where it is, make sure no young are trapped inside, and exclude the animal through a suitable exit. Poison, improvised traps, and sealing holes while an animal is inside can cause serious harm and create a larger problem.
Confirm That an Opossum Is in the Roof
Noise alone does not identify the animal. Opossums, squirrels, raccoons, bats, and rats can all enter roof spaces, and the right response depends on the species. Opossums are usually active at night, but their activity patterns can overlap with other wildlife. Scratching, movement, droppings, and disturbed insulation may provide clues, but none is conclusive on its own.
Look for signs from a safe distance, preferably in daylight. Check the roofline, soffits, vents, and the places where utility lines or pipes enter the home. An opening large enough for an animal may be hidden behind damaged trim or vegetation. Do not reach into a gap, lift roofing, or climb onto a roof to investigate. An animal may defend itself if cornered, and roof work can be hazardous.
A motion-activated camera aimed at a suspected entry point can help show whether an animal comes and goes. A wildlife-control professional can identify signs and inspect difficult or unsafe areas. Correct identification matters: for example, bats may be protected under state or federal rules, and their exclusion requires specialized timing and methods.
Why an Opossum May Enter an Attic
An attic can offer shelter from weather and predators, especially when an animal finds an opening near an eave, vent, or roof junction. Nearby food sources, such as unsecured trash, pet food, fallen fruit, or accessible compost, may also attract wildlife to a property. Removing attractants will not remove an opossum already inside, but it can make the site less appealing once the animal leaves.
Opossums are not usually trying to attack people. They may hiss, bare their teeth, or appear motionless when frightened. These behaviors are defensive, not a reason to approach or handle the animal. Keep people and pets away from the attic access and any suspected entry point while the situation is assessed.
What to Do Before Trying to Remove It
Keep people and pets away
Close the door to the attic or other affected area, if possible, and prevent children and pets from entering. Do not corner the animal or block its suspected exit while it is inside. If an opossum enters a living area, keep a clear route to the outdoors only if it can be done without approaching or confining it; otherwise, contact local animal control or a wildlife professional.
Check for dependent young
Before exclusion, determine whether the animal may have young in the attic. Opossums carry very small young in a pouch, and older young may ride on the mother’s back. Young left behind can die if an adult is excluded, leading to odor, sanitation concerns, and a more complicated removal. Do not assume an apparently empty nest means there are no young. A professional can check the space and advise on the safest timing.
Consider local rules and property conditions
Wildlife laws and control requirements differ by state and locality. Before trapping, relocating, or otherwise handling an opossum, check with the state wildlife agency, local animal control, or a licensed wildlife-control operator. Some jurisdictions restrict relocation, require permits, or specify how wildlife may be handled. Renters should notify the landlord or property manager, and homeowners should check whether roof repairs need a qualified contractor.
How to Get Rid of a Possum in the Roof Humanely
Use professional exclusion when access or safety is uncertain
A licensed wildlife-control professional is often the most reliable option when the entry point is high, the animal’s identity is unclear, young may be present, or the attic is difficult to inspect. The professional should explain how the animal will be removed, how young will be protected, and what repairs will prevent re-entry. Ask whether the service includes follow-up inspection and a written estimate.
Choose someone experienced with humane wildlife exclusion rather than a service that relies on poison or promises instant removal. The National Wildlife Control Operators Association provides a directory, but homeowners should still verify licensing and local requirements. A qualified roofer or contractor may be needed to repair structural damage after the wildlife issue is resolved.
Consider a one-way exit only after checking for young
When it is appropriate and legal, a one-way exclusion device can let an opossum leave while preventing it from re-entering. It must be installed at the active entry point and used only after confirming that dependent young are not inside. A poorly placed device can trap the animal, block the wrong opening, or allow it to find another way into the home. For these reasons, one-way doors are best installed and monitored by a professional.
The exit should be monitored to confirm that the animal has left. Only after activity has stopped and the space has been checked should the opening be permanently repaired. Sealing all possible gaps at once, before confirming an exit, can trap an animal indoors or separate a mother from young.
Use exclusion rather than bait or poison
Poison is not an appropriate solution for an opossum in a roof. It can expose children, pets, and non-target wildlife to toxic substances, and a poisoned animal may die in an inaccessible space. The same concern applies to repellents that make unsupported claims or products not labeled for the intended use. Avoid mothballs, ammonia, smoke, and other improvised deterrents; they can create health, fire, or property risks without reliably solving the problem.
Live trapping is not automatically humane. Trapping can injure or stress an animal, and releasing it elsewhere may be unlawful or may simply transfer the problem. If trapping is considered, it should be handled in accordance with local rules by a qualified professional who can address the animal’s welfare and the presence of young.
What Not to Do
- Do not seal an opening while the opossum may be inside. It could become trapped, die, or damage the roof while trying to escape.
- Do not try to grab, corner, or carry the animal. A frightened wild animal can bite or scratch.
- Do not use poison, glue traps, or fire. These methods can cause prolonged suffering and create additional hazards.
- Do not rely on sound or scent devices as a complete fix. They may not drive an animal out and cannot repair an entry point.
- Do not climb onto a roof without proper training and equipment. A fall can be more dangerous than the wildlife problem.
- Do not sweep or vacuum droppings before learning how to clean them safely. Contaminated material may require protective equipment and careful handling.
Prevent Opossums From Returning
Once the animal is confirmed out, repair the entry point with durable materials suited to the location. Depending on the damage, that may mean replacing broken soffit or fascia, repairing a roof vent, or securing a gap with suitable hardware cloth. Foam alone is generally not a durable wildlife barrier because animals can chew or pull it away. Repairs should preserve required ventilation and drainage; blocking a vent can create moisture or heat problems.
Inspect the full roofline, not just the opening where the animal was seen. Look at eaves, gable vents, chimney areas, loose flashing, and gaps around pipes and cables. Trim branches that provide easy access to the roof, while following safe tree-trimming practices. Keep garbage in secure containers, bring pet food indoors at night, and clean up fallen fruit where practical.
After repairs, monitor the area for renewed noises, disturbed materials, or signs of activity. A camera or periodic exterior inspection can help. If sounds continue, do not assume the original animal is still present; another animal may be using a different opening, or the noise may have another source.
Health and Cleanup Precautions
Opossums can carry germs and parasites, as can other wildlife. Avoid direct contact with the animal, its urine, feces, nesting material, or contaminated insulation. Keep pets away from droppings and do not let them investigate the attic. If anyone is bitten or scratched, wash the wound promptly with soap and running water and contact a healthcare professional or local health department for advice. Animal-control authorities can advise what to do if an animal appears sick, injured, or unusually aggressive.
For cleanup, follow guidance from local public-health or wildlife authorities. Wear appropriate protective equipment, avoid stirring up dust, and use cleaning products according to their labels. Extensive contamination, damaged insulation, or droppings in an enclosed space may call for a professional remediation service. The Centers for Disease Control and Prevention provides general guidance on cleaning areas contaminated by rodents; wildlife-specific conditions may require additional local advice.
When to Call for Help
Contact a wildlife-control professional or local animal control if the animal is trapped, injured, behaving abnormally, or located near people who cannot be kept away. Professional help is also advisable when young may be present, the species is uncertain, the access point is on a steep or damaged roof, or exclusion would require opening walls or removing building materials.
For a straightforward case, the key steps remain the same: confirm the animal, protect any young, allow a safe exit, verify that the space is empty, and repair the entry point. This approach addresses both the immediate problem and the conditions that allowed an opossum to get into the roof.
Reliable Guidance and Further Information
Local rules and wildlife conditions vary, so official advice should take priority over general instructions. Useful starting points include the Humane Society of the United States’ opossum guidance, the National Wildlife Control Operators Association, and the CDC’s information on wildlife and health. State wildlife agencies and municipal animal-control offices can provide location-specific information about permits, seasonal restrictions, and approved removal options.
