When it comes to invasive species in the UK, few are as troublesome as the Glis Glis (Edible Dormouse). Also known as the Fat Dormouse, these rodents were introduced in 1902 by Lord Rothschild in Tring, Hertfordshire. Since then, they have multiplied and spread, causing significant issues for homeowners, businesses, and the environment. While their fluffy appearance may seem harmless, the damage they inflict on properties and ecosystems makes them a serious pest.
How Did Glis Glis Become an Invasive Species in the UK?
Originally native to central and southern Europe, Glis Glis were brought to the UK by accident—or perhaps as a curiosity. Since their introduction, they have thrived in the wild, particularly in the woodlands and rural areas of southern England. With no natural predators in the UK and an ability to adapt to both urban and countryside settings, their numbers have grown alarmingly.
The population initially remained concentrated around Tring, Hertfordshire, but has since expanded into neighbouring counties, including Buckinghamshire, Oxfordshire, and Bedfordshire. Their spread has been aided by their excellent climbing abilities and preference for nesting in roof spaces, enabling them to establish populations in both rural and suburban areas.
Unlike native dormice, Glis Glis are much larger, often reaching up to 19 cm in body length with a bushy tail adding another 14 cm. Their ability to climb, gnaw, and nest in lofts, walls, and attics makes them a serious nuisance for property owners.
The Property Damage Caused by Glis Glis
Homeowners and businesses unfortunate enough to host a Glis Glis infestation often face costly repairs and ongoing disruptions. These rodents are particularly destructive due to their gnawing habits and nesting behaviours. Here are some of the key ways they cause damage:
Electrical Wiring: One of the most dangerous aspects of a Glis Glis infestation is their tendency to chew through electrical wiring. This can lead to power outages, costly rewiring, and, in extreme cases, fire hazards.
Insulation Destruction: These rodents frequently nest in attic insulation, tearing it apart to create bedding materials. This can lead to increased heating costs and reduced energy efficiency in homes and commercial buildings.
Structural Damage: With their powerful teeth, Glis Glis can gnaw through wood, plastic, and even some metal fittings. Over time, this can weaken structural components and require expensive repairs.
Noise Disruptions: As nocturnal animals, Glis Glis are most active at night. Their constant scratching, scurrying, and chewing can make it difficult for homeowners to get a good night's sleep.
Contamination: Like all rodents, Glis Glis leave droppings and urine behind, which can create foul odours and pose health risks due to bacteria and allergens. Their nests can also attract other pests, such as mites and fleas.
The Environmental Impact of Glis Glis
Beyond their impact on human properties, Glis Glis pose a serious environmental threat. Their growing population competes with native wildlife for food and nesting sites, which can disrupt local ecosystems. They consume large amounts of fruit, nuts, and tree bark, which affects natural food chains and can damage woodland habitats. In some areas, their presence has led to reduced populations of native dormice and birds.
Additionally, Glis Glis have been known to raid bird nests, consuming eggs and chicks, further contributing to the decline of certain bird species. Their ability to thrive in both natural and urban environments makes them particularly difficult to control, allowing them to spread unchecked if not managed effectively.
How to Deal with a Glis Glis Infestation
Due to their protected status under the UK Wildlife and Countryside Act, Glis Glis cannot be trapped or killed without a license. This means that professional pest control services are required to remove them legally and effectively.
