Plastic pollution is a pressing issue that affects a wide range of ecosystems and species. While the impact of plastic on marine life has been well-documented, there is also growing concern about its effects on terrestrial creatures, such as squirrels. Squirrels, known for their agility and curiosity, have been observed interacting with plastic in various ways, from chewing on plastic items to incorporating plastic waste into their nests. This behaviour can lead to property damage and even pose health risks to the squirrels themselves. Understanding the reasons behind these behaviours is crucial for developing effective strategies to protect both human infrastructure and squirrel welfare.

What You'll Learn
Squirrels use plastic waste to build their nests
Squirrels have been photographed using plastic waste to build their nests. In 2018, scientists discovered that squirrels in urban areas had been using plastic waste as a building material for their nests. Indian palm squirrels (Funambulus palmarum) are using plastic bags, plastic threads, and cigar butts along with natural materials in urban areas as nesting materials instead of leaves, twigs, shredded bark, mosses, and other soft materials.
The use of plastic for nest-building by squirrels is an example of how these creatures are adapting to changes in their habitat. In urban areas, trees are scarce, but plastic material is not. The proportion of anthropogenic (artificial) material used in nest-building is directly related to the extent of urbanization.
Photographer Henry Jacobs captured images of a squirrel using plastic bags to build its nest in London. Jacobs observed the squirrel exhibiting "odd" behavior as it struggled under the bulk of the plastic bags it was carrying. He commented: "It's a real shame that people want to spoil the environment by throwing rubbish about... I just think it's such a shame."
Plastic pollution is impacting various species in different ways, including the deaths of sea animals such as dolphins, whales, and turtles, which ingest plastic that resembles food. A study published in May 2019 suggested that plastic pollution in oceans could be suffocating the planet by harming tiny microorganisms responsible for a significant portion of the world's oxygen production.

Plastic ingestion may accumulate in squirrels' guts
Squirrels are known to chew on plastic items, including plastic pipes, siding, garden equipment, and furniture. They have well-developed jaw muscles and chisel-like front teeth that continue to grow throughout their lives, which they must file down by gnawing on hard objects. While plastic is not a suitable food source for squirrels, they may ingest small pieces while chewing on plastic items or when using plastic to build their nests.
The impact of plastic ingestion on squirrels' guts has not been extensively studied, but it is known that plastic ingestion can harm squirrels' digestion and overall health. Plastic pollution has been shown to negatively impact various animal species, including marine life such as whales, turtles, dolphins, and sea birds, which often mistake plastic for food.
When plastic is ingested, it can accumulate in the digestive tract and lead to health issues over time. Small pieces of plastic can become lodged in the intestines, causing blockages and impairing the absorption of nutrients. Additionally, chemicals from the plastic may be released into the body, potentially leading to toxicity and affecting the functioning of vital organs.
While the specific effects of plastic accumulation in squirrels' guts are not well-documented, it is reasonable to assume that it could have similar consequences to those observed in other animals. Prolonged exposure to plastic pollutants can cause inflammation, damage to the digestive system, and even contribute to the development of certain cancers.
To mitigate the potential harm caused by plastic ingestion, it is important to minimize the presence of plastic waste in the environment and to take steps to deter squirrels from chewing on plastic items. This can be achieved through the use of repellents, such as capsaicin-based sprays, vinegar, garlic, or essential oils, as well as by securing food sources and regularly cleaning outdoor spaces to remove any food scraps that might attract squirrels.

Plastic production has made squirrels' natural habitats unsafe
Squirrels, known for their agility and curiosity, often interact with plastic items in their surroundings. This includes plastic garbage bins, bird feeders, and storage containers, which they may target in search of food. As a result, they end up ingesting plastic, which can have detrimental consequences for their health. Plastic ingestion can disrupt their digestion and overall well-being, posing significant health risks.
Additionally, squirrels have been observed using plastic waste to build their nests. In 2018, scientists reported that squirrels were incorporating plastic bags and scraps into their nests, an unfortunate adaptation to the availability of human-generated waste. This behaviour not only affects the squirrels but also contributes to the broader issue of plastic pollution. As plastic waste breaks down into microplastics, it can enter ecosystems and harm various animal species, including dolphins, whales, and turtles.
The presence of plastic waste in squirrels' natural habitats also leads to safety concerns. Squirrels, with their strong jaws and sharp teeth, can cause significant damage to household items, outdoor furniture, vehicle wiring, and even building structures. This destructive behaviour can result in costly repairs and create unsafe conditions for both humans and wildlife.
To mitigate the impact of plastic production on squirrels and their habitats, it is essential to reduce plastic waste and properly dispose of plastic items. By minimizing the availability of plastic waste in squirrels' environments, we can help reduce the risks associated with plastic ingestion and nest-building. Additionally, implementing deterrents, such as using repellents or covering plastic components with wire mesh, can help prevent squirrels from chewing on plastic items.

Squirrels are attracted to plastic due to their curious nature
Squirrels are curious and playful creatures with strong jaws and sharp front teeth that never stop growing. To prevent overgrowth, they must constantly chew on hard objects to file their teeth down. In urban and suburban environments, plastic is often an accessible choice for this purpose. Squirrels are known to chew on plastic items such as plumbing pipes, plastic benches, and vinyl siding. They may also chew through plastic garbage bins, bird feeders, and storage containers to reach food or edible remnants inside.
The consequences of squirrels chewing on plastic can be costly and inconvenient, as they can destroy outdoor furniture, pipes, and siding, leading to expensive repairs. Squirrels have also been observed using plastic bags and scraps to build and line their nests, which can be hazardous to their health. Plastic ingestion can affect their digestion and overall health.
To deter squirrels from chewing on plastic items, several methods can be employed. One approach is to use repellents such as capsaicin-based sprays (made from chili peppers), vinegar, garlic, or essential oils like peppermint or eucalyptus. Applying these substances to plastic surfaces can make them unappealing to squirrels. Another strategy is to prevent access to plastic items by using wire mesh or hardware cloth to cover areas with plastic components, such as vents, pipes, or garden furniture.
Additionally, it is important to secure food sources and store them in metal or heavy-duty plastic containers with tight-fitting lids. Regular cleaning of outdoor spaces to remove food scraps and debris can also help deter squirrels. By understanding squirrel behavior and implementing these deterrents, humans can coexist peacefully with these curious creatures.

Plastic production has led to an increase in human-squirrel conflict
Squirrels are known for their strong jaw muscles and constantly growing front teeth, which they must file down by gnawing on hard objects. While they typically chew on woody plant materials, seeds, and nuts, they have also developed a taste for plastic. This is particularly true in urban and suburban environments, where plastic is often easily accessible.
Squirrels have been observed chewing on a variety of plastic items, including plastic pipes, siding, garden equipment, and even recycled plastic benches. This can lead to costly repairs as squirrels can destroy outdoor furniture, pipes, and vehicle wiring. In addition, plastic ingestion can harm squirrels, affecting their digestion and overall health.
One of the most surprising ways that squirrels have started to use plastic is in nest-building. In 2018, scientists discovered that squirrels were using plastic waste to build their nests, with photographer Henry Jacobs capturing startling images of a squirrel struggling under the weight of plastic bags it was carrying. This phenomenon has been observed in other animal species, such as whales and turtles, who ingest plastic pollution floating in the oceans, often with fatal consequences.
To reduce human-squirrel conflict, people can take measures to deter squirrels from chewing on plastic items. This includes using commercial or homemade repellents, such as capsaicin-based sprays, vinegar, garlic, or essential oils. Preventing access to plastic items, using wire mesh or hardware cloth to cover areas with plastic components, and wrapping plastic pipes or cables with durable sheathing can also be effective. By understanding squirrel behavior and implementing these deterrents, humans can coexist peacefully with these curious creatures.
