A gray, cat-sized animal wanders across your backyard after dark, pauses beneath the bird feeder, and then disappears under a nearby deck. The next day, you describe it to a neighbor and hear two different names: possum and opossum. That often leads to the same question: possum or opossum, which one is actually living around your St. Charles home?
While many people use the names interchangeably, Missouri homeowners are almost always talking about the Virginia opossum. In this guide, you’ll learn the difference between possums and opossums, why the names are frequently confused, where opossums are commonly found around Missouri homes, and when to contact professionals for opossum removal.
Key Takeaways
- The opossum is a marsupial that may show up around your home looking for easy food sources, and knowing what draws them in can help you take the right steps.
- Opossums can create entry points through soffits, fascia, roof voids, and eaves, so a thorough property inspection is an important first step toward addressing the problem.
- If an opossum is active in your structure, trapping and removal should come before any exclusion or repair work to seal entry points.
- Wildlife service from Holper’s typically includes a full exterior inspection, humane trapping, animal removal, and a bid for repairs to help prevent re-entry through the same opening.
How to Identify Possums and Opossums
The Virginia opossum is the only marsupial species native to North America. Recognizing this animal and the signs it leaves behind can help you understand what is happening around your home.
Opossums are roughly the size of a house cat, with grayish-white fur, a pointed snout, hairless ears, and a long, bare tail. Their hind feet have an opposable thumb-like toe that leaves a distinctive track.
How to Tell Possums and Opossums Apart
In everyday conversation, many Americans use “possum” and “opossum” interchangeably when referring to the Virginia opossum. Technically, however, possums are different animals native to Australia and nearby regions.
True possums are a separate group of species native to Australia. If you are seeing a cat-sized, gray-furred animal with a pointed face and bare tail in Missouri, you are dealing with the Virginia opossum.
The easiest way to remember the difference is that Missouri is home to opossums, not true possums. Most people shorten the name to “possum,” which is why both terms are commonly used for the same animal in everyday conversation.
How to Spot Opossum Activity Inside Your Home
Opossums that enter a structure often announce themselves with scratching or shuffling noises, especially at night. You may notice droppings in attic spaces or along pathways the animal uses. A musty odor can develop when an opossum has been nesting inside for a period of time. Disturbed insulation or nesting material in an attic is another common indicator.
Where Opossum Activity Shows Up Around Homes
Opossums tend to seek shelter in yards that offer cover and food access. You may spot overturned trash cans, disturbed garden beds, or tracks in soft soil. They are nocturnal, so direct sightings often happen at dusk or after dark near garages, decks, and outbuildings. Droppings along fence lines or near foundations can also signal regular visits.
Exterior Entry Points Opossums Use
Holper’s technicians inspect the soffit, fascia, roof voids, wire voids, pipe voids, and eaves of the home for any entry points. Opossums can squeeze through gaps that look too small for an animal of their size.
Damaged soffit panels, uncapped chimneys, open roof vents, and gaps where utility lines enter the structure are all pathways they may exploit. In most cases, the entry point can be located from the exterior during the inspection.
Why Opossum Problems Develop
Opossums are opportunistic animals that have adapted well to urbanization. They will eat any plant, insect, or other animal food that is readily available, which means residential properties can become a consistent habitat. Understanding what draws opossums to your home is the first step toward addressing the problem.
Outdoor Nesting Areas for Opossums
Opossums look for sheltered spots that offer cover and easy access to food. Woodpiles, dense shrubs, crawl spaces beneath decks, and similar areas around your yard can serve as suitable habitat. Because these animals have adapted so well to neighborhoods, they settle into spots that mimic the natural cover they would find in wooded environments.
Food and Shelter That Attract Opossums
One of the most common attractants is pet food left outdoors. Pet foods left out at night can attract many animals, including opossums. Insects, fallen fruit, pet food, and other readily available food sources can also attract them. The combination of accessible food and nearby shelter makes a yard especially appealing as an ongoing habitat.
How Opossums Move Around Homes
Opossums investigate properties in search of food and denning sites. They may investigate gaps along the roofline, utility entry points, and other vulnerable areas. Their adaptability to developed areas means they move through residential landscapes, following paths between food sources and resting spots.
Trails and Entry Points Opossums Use
Opossums often follow consistent pathways to and from a structure. Entry points typically involve gaps in the soffit, fascia, or eaves, as well as uncapped openings along the roofline. A technician familiar with opossum habitat patterns will inspect the exterior to locate these access points.
Risks From Opossums
Opossums may seem harmless when they pass through your yard, but problems can develop when they move into your home’s structure. Understanding the risks tied to opossum activity helps you decide when the situation calls for a closer look.
Health Risks Linked to Opossums
One of the less obvious concerns with opossums is the parasites they can carry. Wild animals, such as opossums, nesting in an attic, fireplace, or crawlspace, can bring fleas into a home. This means you can end up with a flea problem even if you do not have pets. Once fleas are introduced to indoor spaces, they can spread through carpeting and upholstered areas.
Property Damage From Opossums
When opossums take up residence in or around a structure, they may use existing openings or create new ones along the soffit, fascia, roofline, or eaves. Once inside, nesting activity in attics or crawlspaces can lead to soiled insulation and accumulated debris. Repairing these entry points after removal may require exclusion work, caulking, chimney caps, screened roof vents, or replacement vent covers.
Food Areas and Opossum Activity
Opossums are opportunistic foragers. When they nest close to your home, they may frequent areas where food sources are accessible. Keeping these areas tidy and secured can reduce the appeal your property holds for wildlife looking for a place to settle in.
When to Look Closer at Opossum Activity
If you hear noises in the attic or notice disturbances around your roofline, it is worth investigating.
An opossum nesting in a structure can introduce fleas and create entry-point damage that worsens over time. A thorough exterior inspection can help confirm whether an animal is using your structure. When the entry point cannot be located from the outside, checking interior spaces where noises are heard may be necessary.
Professional Pest Control for Opossums
When an opossum moves into your attic, crawlspace, or under a deck, the situation calls for more than a quick fix.
An approach that combines prevention, a full-property inspection, and trapping by a trained technician gives you a clear path toward resolving the problem and keeping your home protected.
How to Reduce Attractants for Opossums
Opossums are drawn to properties that offer easy food and shelter. Removing attractants is the first step in discouraging them from settling in. Keep outdoor trash cans sealed with tight-fitting lids, and avoid leaving food sources accessible overnight.
If any rodent control measures are in use nearby, remove and dispose of carcasses right away of dead rodents to prevent accidental poisoning of wildlife and pets that might eat a dead animal, as UF/IFAS Extension advises. Cleaning up fallen fruit and securing compost bins also helps reduce what draws opossums to your yard.
Why Opossum Control Starts With Inspection
At Holper’s Pest & Animal Solutions, the process begins with identifying the problem over the phone by asking about the type of activity, its location, and how long it has been occurring before scheduling an on-site inspection.
We request the homeowner be present so the technician can ask about problem areas and know where to start. The technician inspects the entire property, beginning with the yard if ground-level activity is involved. From there, the inspection moves to the soffit, fascia, roofline, and eaves, looking for any entry points.
The entry point is typically located from the exterior, so an interior inspection is usually not necessary. If the exterior check is inconclusive, the technician moves inside to check the attic or other areas where noises have been heard.
What to Expect During Professional Opossum Treatment
After the inspection, the technician presents findings, suggestions with pictures when possible, and the cost. If you approve the proposal, a trap is set during that same visit. Holper’s provides ground trapping for opossums, using both live cage traps and lethal traps depending on the situation, budget, and location of the entry point.
To keep costs down, we ask you to visually check the trap daily. When an animal is present, you notify us, and a technician picks it up within 24 hours. During that pickup visit, another trap is placed, and a cardboard monitor is set over the entry point to determine whether additional animals are still using it. A wildlife technician is on call during weekends and holidays, so trapped animals are handled within 24 to 48 hours of notification.
What to Expect From an Opossum Control Plan
Once trapping is complete and the opossum has been removed, Holper’s provides a bid to repair and exclude the entry point. This can include exclusion work, caulking, soffit or fascia repair, installing chimney caps, screening roof vents, or replacing vent covers.
Exclusion work carries a 12-month guarantee for the specific entry point that was repaired. If an animal creates a different entry point later, the trapping process would begin again, as the guarantee applies only to the excluded opening. Holper’s follows the Missouri Department of Conservation guidelines throughout the process, using humane and lethal options when necessary.
Bottom Line on Possums and Opossums
Whether you call them possums or opossums, these animals are opportunistic and can become a nuisance when they find access to your home or property.
Addressing an opossum issue involves identifying how the animal is getting in, removing it through proper trapping, and then repairing the entry point so the problem does not repeat. Holper’s Pest & Animal Solutions follows Missouri Department of Conservation guidelines and offers a 12-month guarantee on exclusion work for the repaired entry point.
If you suspect opossum activity around your home, contact Holper’s to schedule an inspection and get a plan in place.
Frequently Asked Questions
How Long Does It Take to Remove an Opossum From a Structure?
The timeline depends on how many animals are present and the time of year. In some cases young animals may not be able to leave the structure on their own, which can extend the process. On average, expect around three additional service visits after the initial trap placement.
What Happens to the Animal After It Is Caught?
Holper’s follows the Missouri Department of Conservation Wildlife Control Guidelines when handling trapped animals. Both humane live cage traps and lethal options may be used depending on the circumstances and location of the entry point.
Where Will the Technician Place the Traps?
Traps are placed along the animal’s pathway to and from the structure rather than inside the attic. Depending on the animal and the surroundings, the technician will position traps on the roof or on the ground and will let you know exactly where each trap is set.
Does Holper’s Repair Entry Points After Trapping?
Yes. Once the opossum has been removed, the technician can provide a bid for repairs and exclusion work. This may include caulking, soffit or fascia repair, chimney cap installation, screening roof vents, or replacing vent covers. The exclusion guarantee covers the repaired entry point for 12 months.
