As winter temperatures drop across Oxfordshire, Glis Glis (edible dormice) become a particular concern for homeowners. During the colder months, these mammals enter hibernation, often seeking out warm, undisturbed spaces such as lofts, roof voids, wall cavities, and sheds. While they are inactive for much of the winter, their presence can still cause issues, including noise disturbances during brief waking periods, insulation damage, and contamination from droppings. Because Glis Glis are a protected species in the UK, their activity must be handled carefully and lawfully.

Winter is an important time to focus on prevention and monitoring. Check lofts, rooflines, and external entry points for gaps, damaged tiles, or overhanging branches that provide access routes. Avoid sealing entry points if Glis Glis are already present, as this can trap animals inside and cause further damage. If you suspect dormice activity, professional pest control advice is essential, particularly from specialists licensed to deal with Glis Glis. Addressing the issue during winter helps minimise disruption and reduces the risk of larger infestations once dormice emerge from hibernation in spring.
