Introduction

The Edible Dormouse (Glis glis) becomes a seasonal nuisance in spring as warmer temperatures wake them from hibernation. Originally introduced to the UK in the early 1900s, these non-native rodents have now spread across southern England. Oxfordshire, including areas such as Didcot and Wallingford, faces increasing reports of dormouse infestations in homes, lofts, and outbuildings.

What is the Edible Dormouse (Glis glis)?

Despite the misleading name, no one eats Edible Dormice in the UK. The Romans once did, but today they are regarded as invasive pests. Measuring around 18cm long with a squirrel-like bushy tail, they appear harmless but quickly cause serious structural damage when they gain access to loft spaces or wall cavities.

Their population thrives in the Chiltern Hills and neighbouring counties due to mild winters, loft insulation that offers ideal shelter, and few natural predators. Unfortunately, their presence inside homes often goes unnoticed until considerable damage is done.

Why Spring Triggers Edible Dormouse Infestations

Edible Dormice hibernate from October to May. As the weather warms, they emerge in search of food, warmth, and secure nesting spots. Properties that have provided shelter in past winters are particularly at risk of reinfestation.

Spring marks their most active period. They chew through insulation, plastic piping, and electrical wires. If one enters your loft, others are likely to follow, establishing a breeding population rapidly.

Common Signs of an Edible Dormouse Infestation

Identifying a Glis glis infestation early prevents expensive repairs. Look for the following signs:

• Scurrying or scratching sounds at night, often from loft areas
• Droppings similar to rats but slightly smaller and more pointed
• Visible damage to insulation, timbers, or electrical wiring
• A strong, musty odour in roof spaces
• Sightings of a large-eyed rodent with a fluffy tail

They are agile, nocturnal, and capable of squeezing through openings as small as 5cm.

Risks to Property and Health

Dormice don’t only disturb your sleep—they damage your home. Their constant gnawing weakens roof timbers and insulation. More alarmingly, when they chew through live electrical wires, they pose a real fire hazard.

Although they don’t commonly transmit disease to humans, their droppings may attract secondary pests such as insects. Pets often detect them before humans do, becoming stressed by the scent and sound of dormice overhead.

Legal Edible Dormouse Control Methods in the UK

Under the Wildlife and Countryside Act 1981, the Edible Dormouse is listed under Schedule 9. This makes it illegal to release one into the wild after capture. Only licensed professionals may carry out removal or control.

Homeowners must not attempt to trap, poison, or handle Glis glis themselves. Doing so without a licence from Natural England risks prosecution. Professional pest control companies, such as Shire Pest Solutions, hold the appropriate licences to manage infestations legally and safely.

Prevention Tips to Keep Glis glis Out of Your Property

The best defence against an infestation is prevention. Take these steps to reduce the risk:

• Inspect rooflines for gaps, damaged flashing, or broken tiles
• Seal entry points larger than 5cm with metal mesh or concrete
• Trim back overhanging branches or dense garden vegetation near the roof
• Avoid leaving bird seed or pet food outside overnight
• Keep bin lids shut and food waste contained

Because dormice often return to established nesting sites, a tailored exclusion plan offers long-term peace of mind.
