What Are Opossums?

Before we answer the big question, let’s first understand what opossums actually are. Opossums are the only marsupials native to North America. The Virginia opossum (Didelphis virginiana) is the most common species found in suburban and urban areas, but other species exist in different regions. They are small to medium-sized animals with a prehensile tail, a grayish-white coat, and a rat-like face.

Key Features of Opossums:

• Size: Opossums are typically between 4 to 14 pounds in weight. Some males may even reach up to 15 pounds, though females tend to be smaller.
• Physical Appearance: They have long, coarse fur that is mostly gray with some white. Their long tail is bare, scaly, and prehensile, helping them balance while climbing or gripping.
• Lifespan: Opossums generally live 2 to 4 years in the wild, though many die younger due to predators, accidents, or disease. Their short lifespan is partly because they are preyed upon by numerous animals, including foxes, owls, and domestic dogs.

Fun Fact: Despite their somewhat menacing look, opossums are marsupials, not rodents. They carry their young in a pouch, much like kangaroos and koalas, making them part of an ancient family of mammals that predates many of the modern creatures we know today.

Opossums’ Role in the Ecosystem

Opossums are crucial players in the ecosystem, contributing to the health of the environment in several ways. Although often viewed as pesky scavengers, they provide valuable services that benefit both nature and humans.

Opossums’ Ecological Impact:

1. Tick Control: One of the most significant contributions of opossums is their ability to control tick populations. Opossums have been observed consuming up to 5,000 ticks per week. This helps to reduce the number of ticks that can transmit diseases like Lyme disease, a growing concern in many parts of the world.
2. Carrion Scavenging: Opossums play an important role in the natural recycling of organic matter by scavenging dead animals, or carrion. This helps to prevent the spread of disease by removing decomposing bodies and promoting the breakdown of organic matter.
3. Pest Control: Their omnivorous diet includes small rodents, insects, and even some fruits. By consuming these pests, opossums help to keep populations of unwanted creatures in check, thus reducing the spread of diseases that these pests might carry.

Opossums are like natural garbage disposals, removing waste and helping maintain a cleaner, healthier environment. Their role in controlling tick-borne diseases and acting as a natural pest controller is more beneficial than most people realize.

Do Opossums Attack Humans?

Despite their valuable ecological role, many people fear opossums due to their unique behavior and appearance. Do opossums attack humans? The simple answer is no, they are not aggressive creatures by nature. In fact, aggression from an opossum is a rare occurrence and typically only happens under certain circumstances, such as fear or when the animal feels cornered or threatened.

Why Do People Think Opossums Attack?

Many of the myths surrounding aggressive opossums stem from misunderstandings about their behavior. Here are a few common misconceptions:

• Playing Dead: One of the most famous behaviors of opossums is their ability to “play dead” when threatened. This tactic, known as thanatosis, can appear like the animal is paralyzed, but in fact, they are only trying to avoid being eaten by predators.
• Hissing and Growling: When faced with danger, opossums may hiss or growl, baring their teeth as a warning. These sounds can make them seem threatening, but they are actually part of a bluffing strategy to deter predators.
• Sharp Teeth: Opossums have sharp, pointed teeth which they can use to defend themselves if absolutely necessary. However, a bite from an opossum is extremely rare, as they are typically more likely to run or climb to safety.

In reality, opossums are incredibly shy and will do anything to avoid conflict with humans. If they feel threatened, they will usually try to escape rather than fight. Rare aggression may occur if they are cornered or feel they have no way out.

Defensive Mechanisms of Opossums

Opossums have a range of defensive mechanisms that help them protect themselves from predators. These tactics are meant to ensure their survival, not to attack or harm others.

1. Playing Dead (Thanatosis)

The act of playing dead is one of the most well-known defense mechanisms of the opossum. When an opossum feels extreme fear or stress, it will collapse and emit a foul-smelling odor. The animal appears lifeless and may even begin to leak fluids to simulate the appearance of decay. This defense tactic, known as thanatosis, is designed to convince predators that the opossum is no longer a viable meal.

This behavior is extremely effective in deterring predators, as many animals prefer to avoid decaying or potentially diseased meat. An opossum that is playing dead is not a threat to humans or animals—it is simply trying to survive.

2. Hissing and Growling

When an opossum feels cornered and has no means of escape, it may resort to hissing or growling to defend itself. This behavior is designed to scare away potential threats by making the opossum appear more dangerous than it actually is. While it may seem like an act of aggression, it is more of a bluff to prevent further escalation.

3. Climbing and Escaping

Opossums are excellent climbers, and if their defensive behaviors don’t work, they will often attempt to escape. They will climb trees, fences, and even walls to avoid danger. This ability to escape is one of the primary reasons why opossums rarely engage in confrontations with humans.

Are Opossum Bites Dangerous?

In rare cases, an opossum may bite if it feels threatened or cornered. However, opossum bites are generally not something to worry about. Unlike some wild animals, opossums are not naturally aggressive toward humans and will only bite as a last resort.

Key Points About Opossum Bites:

1. Rabies Risk: One of the most common concerns when it comes to wild animal bites is the risk of rabies. Fortunately, opossums are very resistant to rabies due to their low body temperature. The virus cannot survive in their system as it would in other mammals. This makes rabies extremely rare in opossums.
2. Other Diseases: While rabies is not a significant concern, opossums can carry other diseases, such as salmonella and leptospirosis. These diseases can be transmitted through saliva or feces, so it’s essential to avoid direct contact with opossums and to be cautious when cleaning up their droppings.
3. Bite Treatment: If you are bitten by an opossum, wash the area with soap and water immediately. Apply antiseptic and monitor the bite for any signs of infection. If the bite is deep or shows symptoms like swelling, redness, or pus, seek medical attention promptly.

Tips for Safe Interaction:

• Avoid handling opossums: These animals are wild and should not be approached or handled, especially if they appear stressed or injured.
• Call wildlife control: If you encounter an injured opossum or one that is in danger, contact a local wildlife rescue or control service for advice on how to proceed safely.
  
  

Health Concerns Associated with Opossums

While opossums are not typically dangerous, they can carry certain diseases that pose health risks to humans and pets. It’s important to be aware of these potential dangers and take precautions when interacting with opossums or their environment.

Common Diseases Linked to Opossums:

1. Leptospirosis: This bacterial infection is often spread through contact with opossum urine, which may contaminate food or water sources. Symptoms include fever, headache, and muscle aches. It is treatable with antibiotics but can cause serious complications if left untreated.
2. Salmonella: Opossums can spread salmonella through their droppings, which can contaminate surfaces or food. This bacteria can cause gastrointestinal issues in humans, such as diarrhea, fever, and stomach cramps.
3. Ticks and Lyme Disease: Opossums are known to carry ticks, which are capable of transmitting diseases like Lyme disease and Rocky Mountain spotted fever. However, because opossums eat ticks, they play an important role in reducing tick populations.

How to Prevent Encounters with Opossums

While opossums are generally non-aggressive, many people prefer to avoid encounters altogether. Thankfully, there are several preventive measures you can take to minimize the risk of attracting opossums to your property.

Preventive Measures:

1. Secure Trash: Opossums are attracted to food scraps, so make sure your trash cans are tightly sealed and stored in a secure area. Consider using animal-proof bins to keep opossums and other wildlife away.
2. Remove Pet Food: Don’t leave pet food outside overnight. This is an easy way to attract opossums to your yard. Instead, feed pets indoors or remove food bowls when pets are finished eating.
3. Seal Gaps: Check your home and property for any gaps, holes, or cracks where opossums could enter. These animals can fit into surprisingly small spaces, so be sure to seal any openings, especially in basements, attics, or under porches.
