Woodlice are small animals measuring about 15mm. They belong to the arthropod class known as crustaceans, and they have a variety of colloquial names, such as potato bugs, Bibble bugs or roly-polys. There are 3,500 known types of woodlice in the world.
Woodlice love moist or humid soil, and are constantly seeking moisture. That is why they are often found in many dark and humid places in your home or yard, such as basements, plants and piles of leaves.
Their diet mostly consists of decaying vegetable material and fungi. Woodlice can sometimes feed on the roots of young plants, thus damaging them. These tiny animals also eat their own faeces which contain the fungi and bacteria that are part of their diet
Woodlice cannot bite you. However, they can become a pest since they reproduce very rapidly and in great quantities. Female woodlice can lay up to two dozen eggs at a time, and they lay about three broods per year.
Woodlice have 14 legs, seven on each side. Therefore, they cannot be considered insects. They are arthropods and are more closely related to crabs since they are part of the crustacean class.
