When tunnels are started in late August or September, the first eggs might not be laid until the following spring. The female usually lays her first eggs about four weeks after entry, and continues to lay further batches at irregular intervals throughout her 2-3 year adult life. Once the beetle has established in logs, early conversion to planks to accelerate the drying process, perhaps combined with kiln drying, is the only option to prevent further activity. Preventive sprays at the forest log dump or mill yard can be of some real value in reducing the incidence of infestation. The oak pinhole borer is the only indigenous member of the subfamily Platypodinae, and one of the few ‘ambrosia beetle’ species found in Britain. The male excavates the first few centimetres of a gallery, which a female will enter and then re-emerge with the male to mate on the bark surface.

Our professional, experienced surveyors will carry out a thorough inspection to assess the extent of any woodworm problem and the type of wood borer involved. As she burrows through the wood, the ambrosia fungi are deposited on the wood and, having been transported by the beetle to a suitable habitat, quickly become established on the tunnel walls and form a thick layer.This layer of fungus provides the nourishment for the adult beetles and the developing larvae. Unlike the fibrous bore dust produced by the adult beetles, that produced by the larvae is granular, and cannot be distinguished from the bore dust made by other ambrosia beetles such as Trypodendon. At first the tunnels (galleries) are confined to sapwood, so the heartwood will not have been penetrated if the logs are converted to planks within the first year of attack.
