Opossums are a common Dallas wildlife visitor, and they present a genuine dilemma: they're actually beneficial animals — they eat ticks, cockroaches, rodents, snakes and carrion — but you still don't want one living under your deck or in your attic. The answer is humane removal plus exclusion, not extermination.
Why opossums matter (in your favor, mostly)
North America's only marsupial, the opossum is nature's pest control: a single one can eat thousands of ticks in a season, along with roaches, rodents and other pests. They're also largely resistant to rabies. So the goal isn't to harm them — it's to relocate them away from your structure and seal the space so the next one can't move in.
Where they shelter
Opossums are opportunists that den in sheltered, hidden spaces: under decks, porches and sheds, in crawl spaces, in attics accessed through roofline gaps, and in garages. They're drawn by available food — pet food left out, unsecured garbage, fallen fruit, and the very rodents and insects they hunt.
Why they become a problem
- Droppings and odor in denning areas, with associated health considerations.
- Structural mess — nesting material and waste under and inside structures.
- Secondary pests — fleas and ticks travel on them.
- Conflict risk — a cornered opossum near pets or children. (They usually “play dead” rather than attack, but it's still a situation to avoid.)
Humane removal & exclusion
- Inspection — confirm the animal, find the den and entry points, check for young.
- Humane removal — live trapping or one-way exclusion, handled to keep mothers with dependent young.
- Exclusion — seal off under-deck, crawl-space and roofline access so it can't be reoccupied.
- Cleanup & deterrence — remove waste, and address the food sources (pet food, garbage) that attracted it.
Prevention
Don't leave pet food out overnight, secure garbage cans, pick up fallen fruit, and seal gaps under decks, sheds and porches. Because opossums are beneficial, the best outcome is one where they keep doing their tick-eating work in the neighborhood — just not under your house.
