Old House Borer (6404)

Old House Borer Larva image

The old house borer is one of the most injurious wood-boring insects inhabiting Pennsylvania. The name is somewhat misleading since a large number of infestations are noticed in homes just four to seven years after construction. The larva bores through wood and also feeds on it. Tunnels made by the larva weaken structural timbers. The borers feed only in pine, spruce, and other coniferous woods.

The old house borer is native to North Africa and is believed to have arrived in North America around 1875. The beetles currently range from Maine to Florida and west to Michigan and Texas.
