Woodlice are not insects as people think. Like lobster and shrimp, they belong to the crustacean class. Oval in shape and grayish in color, they are approximately 13 mm to 15 mm long. Their backs are made of a soft shell. They have 7 pairs of legs and 2 pairs of antennae.
Woodlice are the only crustaceans that are entirely terrestrial. They are able to move under a surface without letting go. They are provided with a rigid, segmented exoskeleton, which is pale yellowish-brown (rather in young people) to blackish to slate gray. Their shell is sometimes almost transparent. In some regions, the woodlouse is called "pig of Saint Anthony" or "cellar pig" or "wall pig"; in others, “wolf louse” or “earth rat”.
Prevention tips and recommendations
The first step is to check and reduce the humidity in the affected areas if necessary. Woodlice are attracted to damp, dark places. We frequently find them in:
- Basements of residences and buildings
- Service cellars
- Under the heating logs
- Dehumidify to reduce the humidity level in the basement as much as possible and ensure that the foundation is free from cracks.
- In plants both indoors and outdoors.
