Woodlice are between 3 to 16mm in length, oval shaped and grey in colour. They are related to crabs, prawns and lobsters, but are the only crustaceans that have adapted to living exclusively on land, although they still need damp conditions to survive.

Where do they live?

Often found under stones, around grids and in moist surroundings under wood and vegetation.

What do they eat?

Woodlice feed mainly on decaying plant materials, but have been known to cause damage to soft fruit.

Pest status:

Woodlice have no significant pest status, as they do not damage buildings or crops, and are harmless to man.

Control Measures:

Woodlice which have invaded a room can be simply eradicated by ordinary cleaning measures such as vacuuming.

Insecticidal Control - Woodlice do not breed indoors. If insecticidal control needs to be exercised, then a dust suitable for the treatment of crawling insect pests should be applied to the infested area, paying particular attention to cracks and crevices.

When using pesticides always follow the instructions on the label!
