Opossums are the animal Irvine residents worry about most and need to worry about least. They are not aggressive, they are not rabid, and on a typical Irvine lot they spend the night working through snails, slugs and fallen fruit. The real issues are narrower than people expect: they den in places you would rather they did not, they leave a mess behind, and if one dies somewhere enclosed you have a genuine problem.
Irvine specifically
Irvine is built for an animal like this. The greenbelt network gives an opossum a continuous route across an entire village without ever crossing open ground, common-area landscaping provides cover at every step, and the canyon-edge villages connect that network directly to preserved open space. An opossum can move from Bommer Canyon into the middle of a finished neighbourhood entirely under cover.
The second Irvine pattern is garages and pet doors, and it accounts for a striking share of our calls here. Opossums climb well and have no hesitation about walking through an open garage or a pet door into a laundry room. Several times a year someone in Woodbridge or Northwood goes out at midnight and finds one standing in the kitchen. That is a frightened animal that came in after the cat’s food bowl, not an intruder, and it usually leaves on its own if you open a door and stand well back.
Where they actually are
Opossums are opportunists rather than engineers. They very rarely dig their own den and instead use whatever is already open, so the search is for existing gaps rather than fresh excavation.
On an Irvine lot the list is decks and raised patios, sheds sitting on soil, spa platforms, the void under a built-in barbecue island, and dense ivy or overgrown bougainvillea along a fence. Garages come up constantly, particularly where the door seal has worn and left a gap at one corner. Unlike skunks, opossums climb, so an attic reached from an overhanging branch or the void above a patio cover is worth checking too, especially in the older villages where the trees now reach the rooflines.
The signs people miss
- Pet food disappearing overnight from a bowl in the garage or on the patio, with the bowl left upright rather than knocked over and dragged.
- Droppings noticeably larger than a rat’s, roughly one to three inches, usually concentrated near the den entrance rather than scattered.
- A heavy, dragging sound rather than a scurrying one. Opossums are slow and clumsy compared with rats or squirrels, and people almost always describe it as something walking rather than running.
- Coarse grey and white hair caught on a torn vent screen, a worn gap under a gate, or the bottom corner of a garage door seal.
How we handle it
The free inspection covers the whole lot rather than just the house, because in Irvine the den is usually in a secondary structure or a garage. What matters most is establishing whether the den is currently occupied and, in spring, whether there is a female carrying young.
The work is cage trapping and exclusion. Once the space is confirmed clear we close it, which on an Irvine property typically means a buried barrier along a deck or shed edge, a new garage door seal, and closing the settled gap where a patio slab has pulled away. Where a pet door is the route in we will tell you plainly that no exclusion work solves it and the door needs to be a locking or electronically tagged one. We will also flag anything likely to need HOA architectural approval before we install it.
On what opossums actually do to a property
It is worth separating real damage from imagined. Opossums do not chew structural wood the way rodents do, they do not tear open ducting or roof vents the way raccoons do, and they will not attack you or your pets. They are also genuinely useful, eating large numbers of snails, slugs and ticks.
Where they cause actual problems is contamination and odor. A garage, deck void or attic used as a den accumulates droppings and urine that soak into insulation and soil, and that material has to come out. The worst version of this job is the one that starts with a smell, because an opossum that dies in an enclosed space is an unpleasant recovery and it is the single most common reason we get called about them at all. If you are smelling something and cannot place it, get someone to look sooner rather than later.

How we handle the animal
Cage trapping and exclusion, not chemicals. We do not apply pesticides, rodenticides or bait on any job.
Every trap we set is checked at least once every 24 hours. Where 14 CCR § 465.5(g)(2) applies it requires trapped animals to be handled in accordance with state regulation rather than moved somewhere else, and we will walk you through what that means for your property before anything is set. We will not tell you a story about releasing the animal in the canyon, because that is not how the regulations work.
Opossum young ride on the mother, which makes spring and early summer jobs materially different. If there is a female with a litter on the property, sequencing the work correctly is the difference between a clean resolution and a set of dead young inside a structure.
Where opossums turn up across Irvine
Opossum calls spread far more evenly across Irvine than skunk or raccoon calls do, because opossums tolerate dense development well and do not need open space nearby. What predicts them is cover and food rather than proximity to a canyon.
That puts the older villages near the top. Woodbridge, University Park, Northwood and El Camino Real have fifty years of mature landscaping, established fruit trees and the kind of overgrown fence lines that give an animal a route and a resting place. The canyon-edge villages see them too, arriving through the greenbelts rather than over the back fence. Higher-density product around the Great Park and the Irvine Business Complex generates a different sort of call, usually tied to shared trash enclosures, courtyard landscaping and outdoor pet feeding rather than structural entry.
Questions we actually get asked
There is an opossum in our garage. Is it dangerous, and should we worry about rabies?
It is not dangerous and rabies is extremely unlikely. Opossums have a low body temperature that makes them poor hosts for the virus and confirmed cases are very rare. The hissing and open-mouth display is a bluff from a frightened animal. Practically: open the garage door at night to give it a clear exit, bring pets inside, remove any food bowls, and do not corner it. Most leave on their own by morning. If it is still there, call us and do not try to catch it yourself.
Can we just wait? We have been told they move on by themselves.
Often they do, since opossums are more transient than raccoons or skunks and will use a den for a few days before moving on. The trouble is that whatever suited this one will suit the next one, so waiting resolves the occupant rather than the situation. It is also a poor plan in spring, when a female with young stays put much longer. If the gap stays open you will be having this conversation again, probably within the year.
Something died under our deck and the smell is awful. Can you get it out without dismantling the deck?
Usually, yes. Most Irvine decks have enough clearance to reach under with the right equipment, and we would far rather work through an existing access point than cut boards. We remove the animal along with the contaminated soil and material around it, then find and close the gap that let it in. What we will not do is promise a date when the residual smell fully disappears, because that depends on how much material absorbed it and how well the space ventilates. If the deck genuinely has to come apart we will tell you before we start rather than halfway through.
The rest of what we do in Irvine
A gap that admits an opossum will admit other things. When we are on an Irvine property we check every structure on the lot, and these are the services most often paired with this work.
Licensed for the work we advertise, and clear about the rest
Wildlife control, structural pest control and construction are three separate licenses in California. Plenty of companies blur that line. We would rather tell you exactly where ours sits.
- Wildlife trapping and exclusion — this is us. Tri County Trappers operates under California Department of Fish and Wildlife Trapping License TP-10188, and every technician on our crew carries their own CDFW trapping license. Not a company license with unlicensed helpers under it. Each one, individually licensed by the State.
- Attic cleanout and decontamination — this is us. Removal, bagging, vacuuming and cleaning of contaminated material. We do not apply pesticides, rodenticides or bait on any job.
- Insulation, wood repair and structural work — not us. Tri County Trappers does not hold a Contractors State License Board license. That work is performed by a licensed contractor. We inspect it, document it and hand over the photographs so nobody starts cold.
- Structural pest control (Branch 2) — not us. If your situation needs it, we say so and point you to a licensed structural pest control operator rather than stretching our own license over it.
General liability, professional liability, workers’ compensation and commercial auto, all current, with limits well above what the State requires of a licensed trapper. Certificates on request, before you let anyone on your roof.
