The Virginia opossum, the only marsupial native to North America, is a common nocturnal presence in suburban and urban environments. These adaptable animals often forage near human dwellings, prompting questions about what they might consume. Homeowners frequently ask whether these opportunistic visitors eat peanut butter. This article provides a direct answer and explores the context of peanut butter consumption regarding safety, nutritional impact, and its use in wildlife management.
The Immediate Answer: Attractiveness and Consumption
The direct answer to whether possums eat peanut butter is an unqualified yes. As omnivores with a keen sense of smell, opossums are readily attracted to the rich aroma and caloric density of the spread. This sticky spread is highly appealing because it represents a concentrated source of fat and protein. The high-calorie content is a strong draw for a wild animal constantly searching for energy to fuel its nighttime activities.
Opossums utilize their prehensile front paws to locate and consume such foods. They are not wary of novel food sources, especially those with strong scents like peanuts. While they may prefer to lick the softer portions, they will consume the entire product. This behavior explains why peanut butter is often cited as an effective bait for various wildlife.
Nutritional Concerns and Safety Risks
Despite its attractiveness, peanut butter is not a safe or healthy food choice for possums. The primary health concern relates to the high levels of fat, sugar, and salt found in most commercial brands. Regular consumption of these processed ingredients can lead to obesity, dental issues, and an unbalanced diet, potentially shortening the animal’s lifespan.
A far more acute danger is the presence of the artificial sweetener xylitol in some reduced-sugar varieties. Xylitol is highly toxic to many mammals, causing a sudden drop in blood sugar (hypoglycemia) and acute liver failure, which can be fatal. Although specific toxicity data for opossums is limited, the danger warrants strict avoidance of any product containing this ingredient. The sticky texture also poses a minor risk, as its dense nature can present a choking hazard or difficulty in swallowing for smaller wildlife.
Possums’ Natural Diet and Feeding Habits
Understanding the opossum’s natural diet provides context for why human foods are nutritionally inappropriate. Opossums are generalist omnivores, consuming a wide range of foods depending on availability. Their natural foraging includes insects, snails, slugs, small rodents, eggs, and carrion, alongside plant matter such as fruits, berries, and grain.
Opossums require a high amount of calcium, which they obtain by consuming the skeletal remains of small creatures. This natural diet is high in fiber and balanced in protein, contrasting sharply with the processed sugars and saturated fats found in commercial peanut butter. The processed nature of human foods does not provide the balanced nutrition required for a healthy wild metabolism.
Using Peanut Butter for Trapping or Deterrence
The high appeal of peanut butter makes it a common and effective lure for trapping opossums. The strong odor encourages the animals to enter live traps, especially when the peanut butter is mixed with other sweet or fibrous items like oats or apples to reduce the stickiness. This combination is frequently used by homeowners and wildlife control professionals to capture and relocate nuisance animals.
Conversely, this attractiveness means that unsecured sources of peanut butter or other high-fat foods will actively draw possums to a property. Leaving pet food outside, not securing garbage cans, or having accessible bird feeders encourages repeated visits. To deter them, the most effective method is eliminating these accessible food rewards, as the animals are nomadic and will move on when their food source disappears.
