A brown beetle, about 1cm long, with pronounced antennae and a tendency to emerge from damp basements and fly about near rivers or estuaries in early summer.
The grubs live in very decayed wet timber such as old jetties or wooden piles. Buildings built over old bombed sites with timbers buried under them are sometimes invaded by these beetles for a few odd days.
REMEDY: A minor pest, they can be mistaken for cockroaches. Select an insect puffer pack labelled for beetle control and apply in all visible crevices. The removal of any obvious rotten wood will alleviate the problem.
