Glis Glis Control
Licensed Glis Glis control tailored to this invasive and disruptive species.
Glis Glis are nocturnal rodents often mistaken for squirrels or mice, but they leave unique signs of activity:
Noises: Loud squeaks and heavy scurrying in lofts at night.
Droppings: Found in insulation or near stored items in lofts.
Chewing: Damage to wiring, timbers, and insulation.
Grease Marks: Oily stains around entry holes or regular runways.
Sightings: Grey, squirrel-like rodents with bushy tails.
Our Approach
Glis Glis can only be managed under licence. Old Bill’s technicians are trained and authorised to carry out this work legally and humanely. Our process includes surveying loft areas, identifying activity, and using approved control methods. Reports are always provided to keep you fully informed.
Glis glis can often be managed by preventing access to roof spaces and buildings, including sealing entry points and installing suitable proofing measures such as mesh over vents and gaps.
Infestations can be particularly problematic as they nest in lofts and wall voids, are nocturnal, and can cause damage through gnawing on timber, insulation, and electrical wiring. They may also be protected in some regions, limiting treatment options.
In these circumstances, a controlled and compliant approach is required, often involving trapping or exclusion methods carried out in line with legal guidelines, along with ongoing monitoring to prevent re-entry.
