woodlice(Porcellio scaber)are small crustaceans that prefer moist environments and are therefore frequent residents of gardens, greenhouses and compost heaps.They also penetrate the house.
They play an important role in the ecosystem by decomposing organic material such as twigs, leaves and old roots and improving the soil. Woodlice find their way into your raised bed because it is moist and there is enough food, such as dead plant parts and humus.
During the day they stay in a suitable shelter and, when threatened, pretend to be dead by curling up into a ball. At night, woodlice leave their hiding places and look for food in cool air. In winter they go into hibernation.
*Ants and woodlice often appear together because they prefer similar moist conditions. Ants can view woodlice as prey. Read about what other types of pests you can discover in raised bedsin this article.
