Habitat |
|
Over 30 species of woodlice are common in Britain, hence we will deal with them in general terms as most are similar morphologically and behaviourally.
The majority of these species are outdoor organisms, some of which are of horticultural significance when they attack plants.
Some woodlice enter dwellings in the cooler autumn and winter months when they may be seen as pests.

Biology |
|
Unlike insects, crustaceans do not have internal channels for moving gas vital to respirations, and use surface area and external gills for the purpose of gas exchange. They are particularly sensitive to water loss and are usually found in damp surroundings.

Pest Status |
|
Crustacea is a large order, most members of which are aquatic.
The woodlice are possibly the best known land living creatures of this class.
Woodlice are generally harmless casual invaders of homes.
|
Control |
|
As woodlice are essentially harmless organisms which do not breed indoors, and tend only to venture inside dwellings for shelter, simple cleaning and proofing of entry points should suffice.
Refuse and harbourage areas adjacent to the perimeter of buildings should be minimized. If necessary, a residual barrier treatment should prevent access.
