Skillful climber, the dormouse is a rodent that appreciates high shelters, such as attics and attics. It quickly becomes a nuisance for man because of the noise it produces and the damage it causes. Protected by European legislation, he can not be killed. But there are effective methods to prevent it from entering homes.

The Dormouse.

Very slender with its big tail, the dormouse is clever to climb in the attic and attics.

How to prevent the dormice from entering the attic and attics?

The dormers particularly appreciate the attic and attics, because they love to live in height. Their great agility to go up the vertical walls allows them to sneak easily into the roofs of houses to settle there. It then becomes necessary to dislodge them.

Take preventive measures

4 preventive and easy gestures make it possible to guard against the invasion of dormers in attics and attics.

  • Outside the house, think about regularly maintain climbing plants which can cover the walls (ivy, for example) by cutting them to 1 m below the access to the attic.
  • Stalking all openings more than 2 cm by putting in a thin wire or blocking them.
  • Under the roof canal tiles, there are often small spaces in which the dormouse can sneak. It will then be necessary obstruct using suitable metal devices.
  • Do not store any food in the attic or the attic.

Use ultrasound devices

Another approach is based on the use ofultrasonic devices. These emit waves not perceptible by man, but sensitive to the ears of the dormice. Imported, the animals will then flee the place where the device was installed.

Warning! Ultrasound does not cross the walls. It will therefore be necessary to position a device in each room. Also pay attention to device models because not all are equal in their effectiveness.

Set traps to capture dormice without killing them

The chickens is a solution that allows to capture the animal alive. This grid trap is to be placed in several places and to be raised frequently, otherwise the dormouse may die of stress due to confinement.

The installation of the trap is simple. Just prime it by positioning inside a bait in the form of fruit. To do this, it is advisable to use gloves so as not to leave its smell. Once the dormouse is captured, release it as far as possible from the dwelling.

NoteThere are also traps to kill the dormice or suitable rodenticide products, but given their protected status (as endangered), it is not recommended to use these methods.

Presentation of the dormouse

The dormouse that one encounters in the houses is often the so-called species of the the burp. It measures between 10 and 30 cm including tail and has a coat between beige and gray, white flanks and belly, round and fairly large ears, eyes circled in black. His tail ends in a white tuft streaked with black.
Omnivorous, he especially likes fruits, seeds, larvae, eggs...
It is found in homes because it is attracted by the presence of shelter (height) and food.

What nuisances for humans?

The nuisances caused by the dormouse or lérot are of 2 orders.

  • Night animal par excellence, it circulates a lot in the attic and on the ceilings and creates a lot of din during the night. This causes a real embarrassment for the inhabitants, coupled with a stress related to the feeling of intrusion into the house.
  • As a rodent, the dormouse tends to nibble partitions and insulators (like glass wool).

The dormouse, a protected animal

In the same way as the bat for example (although the regulation is different), the dormouse is considered by the European legislation (Appendix III to the Convention on the Conservation of European Wildlife and Natural Habitats) as a protected animal because the species is in decline. This is paradoxical when we see that it can come out of its natural habitat and invade homes.

For this reason, it is forbidden to kill this animal. Must therefore favor non-lethal capture methods where the preventive methods.
