Porotermes  

Only P. adamsoni is known to be a pest. It attack softwood posts and flooring, hardwood poles, house piers, bridge timbers and fence posts (Hill, 1942). It is of considerable economic importance as a pest of Eucalyptus, especially in south-east Australia and Tasmania, especially in the alpine forests of New South Wales (Greaves, 1962, 1965). It can potentially do more damage than other termites (such as Coptotermes) because it attacks sapwood as well as heartwood. P. adamsoni is rarely found attacking houses (Hadlington, 1987).
