Bark Beetles



Bark beetles of the Families Scolytidae and
Bostrichidae occasionally tunnel the bark or wane of
exposed floor joists, rafters, studding and sheeting,
especially of new houses, or where older houses have been
remodeled with new lumber. These beetles limit their
taste almost entirely to the bark. If they enter the
wood, it is only for very short distances. They normally
do not tunnel the wood as do the true powder-post
beetles. The annoyance stops when they have consumed the
bark or if the bark is mechanically stripped from the
lumber.

The true powder-post beetles and the beetles that
infest only bark have one thing in common. They both
produce a fine sawdust or wood powder about the texture
of wheat flour. The powder will be the same color as the
bark and wood from which it is produced.

The color of the sawdust plus a close inspection of
the places where the beetle grubs are working will tell
immediately the kind of problem you have. See the section
on powder-post beetles for a description of the damage
done by these insects.
