The term "powderpost beetle," used broadly, applies to any of the following three closely related
families: Lyctidae, [a], and [b].
-
The [a] has a

Drywood termite infestations are
frequently detected by
the presence of the
six-sided [a] which
have been pushed out
of the galleries.

-
Borates are toxic to [a] ,
but are not considered significantly
hazardous to [b].
- many termite species
- humans
-
Termites other than [a] termites are
divided into two groups:
drywood and [b] termites.
-
The largest termites are
found in the [a] termite group;
they require wood with a
high degree of [b].
-
Beetles belong to the
Order Coloeptera, the largest of
the insect orders. The [a] stage is
responsible for almost all
damage done to wood by beetles.
larval
-
The first step in controlling
wood decay is to locate and
eliminate the source of [a].
This can usually be
accomplished by mechanical
alterations which provide for
adequate circulation of [b].
