Glis glis look cute, but they can cause considerable damage to your home. In fact they are much more destructive than rats or mice.

More than 100,000 glis glis are now running wild in Buckinghamshire, Hertfordshire, Bedfordshire, Berkshire, Essex, Oxford and London. Their numbers have doubled in just 10-years which means they are invading more properties.

What are glis glis?

Glis glis have small ears, big eyes, short legs and a 6-inch-long bushy tail, a look like a young squirrel. However, a glis glis is actually a large dormouse, called a European edible dormouse because the Romans used to eat them.

Zoologist Lionel Walter Rothschild first brought glis glis to Britain for his private collection in Tring, Hertfordshire. In 1902 six of them escaped and they’ve been breeding in the wild ever since.

What problems do glis glis cause?

Glis glis have become a real problem in the countryside, destroying crops and trees. In urban areas they find their way into buildings for warmth and shelter. Apart from the obvious hygiene issues, they cause significant damage by gnawing cables and wires which can be a fire hazard. They are noisy, running around in lofts and wall cavities and getting into airing cupboards, store rooms and kitchens in their quest for food. An infestation can comprise large numbers; a record 145 glis glis were removed from a house in London.

Why use a professional company to remove glis glis?

Glis glis are protected under the Wildlife & Countryside Act 1981 so if you have an infestation you will need to contact a pest control company which is authorised under licence to trap and remove them. We have a licence and have over 35-years’ experience dealing with them.

How do we get rid of glis glis in a loft?

We lay traps to kill glis glis. Legally, these types of traps have to be checked daily so can only be used if you are able to do so. If you see or hear an animal caught in one the the traps that is in destress you must phone our office. There is no need to call the office if the animal is dead.

It can take several visits to eradicate the current infestation. It is important that the property is proofed by blocking any holes and points of access as soon as the treatment has been completed to prevent other glis glis from moving into the vacant territory. This can’t be done until the current infestation is eliminated as glis glis can cause further damage to the roof as they try to get in. 

What preparation do you need to make prior to treatment?

  • Leave any droppings or damage for the technician to look at.
  • Don’t attempt to block any entry holes.
  • Keep a record of where you see glis glis and ask your neighbours if they have any.

Biocide treatment

Once the current glis glis infestation has been eradicated from your home or business premises and the access points have been removed, we can treat the areas which have been contaminated by glis glis using a biocidal spray.

What do you need to do after treatment to protect a property from glis glis long term?

 To effectively protect a property from glis glis infestations long term, proofing needs to be carried out by a professional pest control technician who understands the behaviour of glis glis. It’s time-consuming and may seem costly, but it prevents repeated visits to get rid of glis glis from your property. Glis glis will return to the same property if they haven’t been eradicated. To find out more see our page on proofing.

When are glis glis most active?

Glis glis usually hibernate from November to May so they start to seek shelter inside properties when the weather becomes colder. Unfortunately, as creatures of habit, they often infest the same properties year after year. In late spring when they come out of hibernation they will be looking for food. Their breeding season is from late June to mid-August so they will make their nests during this time and breed.

Why is it necessary to remove loft insulation after a glis glis infestation?

Glis glis cause major damage to loft insulation by tearing it up for bedding and making nests. If there’s a major infestation then the loft insulation will be heavily contaminated with droppings and urine.

We offer a loft insulation replacement service. After getting rid of the glis glis we can remove and dispose of the loft insulation safely. We will then vacuum the loft space and apply a biocide spray before installing fresh, new insulation. To find out more see our page on loft insulation removal & installation.

The cost depends on the size of the loft space. Call 0800 026 0308 for a quote.

What are the signs of a glis glis infestation in a loft?

  • Droppings.
  • The smell of urine or areas which are stained and could be attributed to urine.
  • Signs of gnawing on wood, metal, plastics and other materials.
  • Gnawed electrical cables.
  • Evidence of nests.
  • Scratching noises and movements in the loft and wall cavities at night as they are nocturnal creatures.
  • Unusual movements in tree branches and bird nests outside the house.
  • Damage to young trees or tree bark in the garden.

PEST UK’s Guarantee

We only guarantee treatments to eliminate the current population of glis glis inside a property, not any glis glis that access the property after the treatment. The access points must be sealed as soon as the current infestation is eliminated.
