Squirrels ingest plastic from bins and garbage cans
Squirrels are known to forage in garbage bins and trash cans, which can lead to plastic ingestion. This behaviour can have negative consequences for both the squirrels and humans. Squirrels may ingest plastic while searching for food, which can harm their digestion and overall health. Additionally, their strong and persistent chewing behaviour can cause significant damage to plastic items, resulting in costly repairs.
Squirrels are opportunistic foragers and are not selective when it comes to finding their next meal. They are attracted to outdoor garbage bins and trash cans, which can provide an abundant food source. Squirrels have strong teeth that can chew through plastic, allowing them to access the contents of garbage bins and trash cans. This can result in scattered garbage, attracting other pests and creating an unsanitary environment.
To prevent squirrels from accessing and chewing on plastic garbage bins and trash cans, several measures can be implemented. One effective solution is to use sturdy, squirrel-proof bins with secure lids that are difficult for squirrels to gnaw through. Metal bins or cans are recommended, as metal surfaces are less appealing for squirrels to chew on. Additionally, ensuring tight-fitting lids and removing food residue can reduce the attraction for squirrels.
Another strategy is to apply repellents to plastic surfaces. Commercial or DIY repellents can be used, such as capsaicin-based sprays, vinegar, garlic, or essential oils like peppermint or eucalyptus. These create a taste or smell that squirrels find unpleasant, deterring them from chewing on treated surfaces. Planting certain plants, such as marigold, daffodils, geraniums, onion, garlic, mint, and chilli peppers, near garbage bins can also help repel squirrels naturally.
Motion-activated sprinklers installed near trash cans can also be an effective deterrent. When activated, the sprinklers startle squirrels and discourage them from approaching the trash cans. Additionally, proper waste management practices can reduce the attraction for squirrels. This includes carefully disposing of food waste through garbage disposals or storing food scraps in the freezer until trash day, minimising odours that may attract squirrels.

Plastic ingestion affects squirrel digestion and health
Squirrels are known to chew on plastic items, including plastic pipes, outdoor furniture, vehicle wiring, and even building structures. This behaviour can cause significant damage to property and vehicles, but it can also have harmful effects on the squirrels themselves.
Squirrels are rodents with well-developed jaw muscles and constantly growing front teeth that must be filed down by gnawing on hard objects. While they typically chew on woody plant materials, seeds, and nuts, they may also turn to plastic as a readily available option in urban and suburban environments. This can lead to plastic ingestion, which can negatively impact their digestion and overall health.
Faith James, an undergraduate student at Concordia College, presented research at The Wildlife Society's virtual annual conference, highlighting the presence of microplastics in the guts of grey squirrels on her college campus. The research also observed the behaviour of campus squirrels as they interacted with different plastic sources. This study demonstrates how plastic ingestion can have detrimental effects on squirrel digestion and overall health.
The exact mechanisms by which plastic ingestion affects squirrel digestion are not explicitly mentioned in the sources. However, it is reasonable to assume that ingesting plastic can lead to blockages or obstructions in the digestive tract, similar to other animals. Additionally, the chemicals and toxins present in plastics may be harmful to the squirrels' digestive system and overall health.
To mitigate the impacts of plastic ingestion on squirrels, it is essential to reduce their access to plastic items. This can be achieved by using deterrents, such as capsaicin-based repellents, bitter-tasting sprays, or ultrasonic devices. Alternatively, physical barriers like wire mesh or hardware cloth can be used to cover areas with plastic components. By implementing these measures, we can help reduce the negative consequences of plastic ingestion on squirrel digestion and health.

Plastic is attractive to squirrels due to its texture and scent
Squirrels are known to chew on plastic items, which can lead to physical damage and safety concerns. This behaviour is driven by their natural instincts and biology. Squirrels, classified as rodents, have well-developed jaw muscles and constantly growing front teeth that must be filed down by gnawing on hard objects. While they typically chew on woody plant materials, seeds, and nuts, they may also be attracted to plastic due to its texture and scent.
The texture of recycled plastic can be irresistible to squirrels, and they may chew on it persistently, leading to damaged items, furniture, and even building structures. This can result in costly repairs and create safety hazards. Additionally, the scent of plastic can also attract squirrels. By understanding the reasons behind squirrel behaviour, we can implement deterrents to coexist peacefully with these creatures.
One way to prevent squirrels from chewing on plastic is to eliminate anything that attracts them to your property. This includes securing food sources and storing them in metal or heavy-duty plastic containers with tight-fitting lids. Regular cleaning of outdoor spaces is also essential to remove any food scraps or debris that might entice squirrels. Applying repellents to plastic surfaces is another effective method of deterrence. Capsaicin-based sprays, for example, create a spicy taste that squirrels dislike, and can be applied to pipes, outdoor furniture, or trash cans.
Homemade repellents can also be created using vinegar, garlic, or essential oils like peppermint or eucalyptus. Providing squirrels with alternative chew toys or strategically placed feeders can also give them a more natural outlet for their gnawing needs. By offering alternative chewing options and using repellents, we can reduce the impact of plastic on squirrels and protect our belongings from damage.

Plastic items are damaged by squirrel chewing
Squirrels are classified as rodents and have well-developed jaw muscles and chisel-like front teeth that can chew through almost anything. As their front teeth grow constantly, squirrels must gnaw on hard objects to file them down and prevent starvation. Unfortunately, plastic items are a common target for squirrel chewing, and this can result in significant damage to the items.
Squirrels may chew on a variety of plastic items, including plastic trays, edging in gardens, vinyl siding on houses, and even recycled plastic benches in parks. This chewing can leave unsightly marks on the plastic items and create potential safety hazards. For example, a plastic item with deep grooves caused by squirrel chewing may become structurally weakened and more prone to breaking.
The texture and scent of some plastics can be particularly appealing to squirrels, making them more susceptible to chewing damage. Additionally, certain colours of plastic may be more attractive to squirrels, as they associate these colours with food sources.
The presence of food sources, tall trees, utility poles, and bird feeders can attract squirrels to an area, increasing the likelihood of plastic items being damaged by their chewing. Squirrels may also ingest plastic particles that can accumulate in their guts, potentially causing health issues for these animals.
To prevent damage to plastic items, deterrents such as bitter apple, peppermint oil, or rodent repellent sprays can be applied to the surfaces. Providing alternative chewing options, such as strategic squirrel feeders or natural outlets like plants, can also help redirect their chewing behaviour away from plastic items.

Repellents can be used to deter squirrels from chewing plastic
Squirrels are classified as rodents and have well-developed jaw muscles and chisel-like front teeth that can chew through almost anything. Their front teeth are kept sharp by gnawing on hard objects, and as they grow constantly, squirrels must file them down or starve. Unfortunately, the texture and scent of plastic can be irresistible to squirrels, leading them to chew on plastic items and cause significant damage.
To prevent squirrels from chewing on plastic, one simple method is to eliminate anything that attracts them to your property. This includes storing food in secure containers and regularly cleaning outdoor spaces to remove any food scraps. Applying repellents to plastic surfaces is another effective strategy. Commercial squirrel repellents designed for gardens and structures are readily available. Alternatively, you can create your own DIY repellent with vinegar, garlic, or essential oils like peppermint or eucalyptus. Capsaicin-based sprays, derived from the active ingredient in chili peppers, can also be applied to plastic surfaces, leaving a spicy taste that squirrels dislike.
For plastic pipes, in particular, you can use capsicum-based sprays or wrap them with metal sheathing. To protect other plastic items, such as vents, pipes, or garden furniture, strong wire mesh or hardware cloth can be used as a barrier. Additionally, certain plants, like mint, marigolds, or daffodils, are naturally unappealing to squirrels and can be planted as a natural deterrent.
It is important to note that preventing squirrels from returning after they have stopped chewing on plastic is crucial. This can be achieved by regularly reapplying repellents, activating deterrents, and keeping the area clean to remove any food sources that may attract them.
