San Antonio is home to a diverse range of wildlife, including a frequently misunderstood creature—the opossum. These nocturnal marsupials often find their way into backyards, alleyways, and even porches, leaving many residents wondering what to do about them. Despite their eerie appearance and reputation as pests, opossums play a crucial role in our ecosystem and are far less troublesome than many believe.
The Truth About Opossums
Opossums are North America’s only marsupials, meaning they carry and nurse their young in a pouch, much like kangaroos. They are omnivores, feeding on everything from fruits and insects to small rodents and carrion. In fact, opossums are excellent natural pest controllers, consuming ticks, cockroaches, and even venomous snakes. Their immune system allows them to resist rabies and most snake venom, making them a valuable ally in keeping certain disease-carrying pests in check.
Are Opossums Dangerous?
Contrary to popular belief, opossums are not aggressive animals. When threatened, they rely on a unique defense mechanism—“playing possum.” This involuntary response causes them to collapse, appear dead, and even emit a foul odor to deter predators. They are generally shy creatures that prefer to avoid human interaction rather than confront it.
What Attracts Opossums to Your Property?
Opossums are opportunistic feeders and will take advantage of easily accessible food sources. Common attractants include:
- Pet food left outside overnight
- Open garbage cans or compost piles
- Fallen fruits from trees
- Overgrown brush and woodpiles providing shelter
By securing trash bins, bringing pet food indoors, and keeping yards tidy, residents can reduce the likelihood of opossums visiting their property.
Humane Ways to Handle Opossums
If an opossum is frequenting your yard, there’s usually no need for alarm. Here are some humane ways to manage their presence:
Let Them Be – In most cases, opossums move on within a few days. They are nomadic and rarely stay in one place for long.
Use Deterrents – Motion-activated lights, sprinklers, or loud noises can encourage them to move along.
Secure Entry Points – If an opossum has taken shelter under a deck or shed, block the entrance after confirming the animal has left.
Call a Professional – If an opossum appears injured or trapped, contact a local wildlife rescue or animal control for assistance.
Coexisting with San Antonio’s Wildlife
While some may view opossums as unwelcome guests, they are an essential part of the local ecosystem. Instead of fearing or harming them, understanding their behavior can lead to peaceful coexistence. By taking simple precautions, San Antonio residents can appreciate these fascinating creatures without unnecessary conflict.
Next time you see an opossum in your yard, remember—they’re not out to harm you. In fact, they may just be helping to keep your home pest-free.
