damages and can reinfest
seasoned wood in a structure
(Termites, powderpost beetles,
old house borers, wood-
decaying fungi)
Old House borer (a longhorned beetle/cerambycid) Which wood-infesting pest usually
leaves heavy damage in finished SOFTwood with
the ONLY external evidence being 1-2 oval exit
holes? Typical control is fumigation for heavy
infestations.
Bark beetles Which wood-infesting pest is found in rough,
bark-covered wood leaving small exit holes 1/8
inch diameter with inner side of bark/wood
surface "engraved" with galleries (NOT
extensive tunnels)? The damage is old, will not
reinfest dried wood, and NO control is required.
The powder is the same color as the bark.
Ambrosia beetles Which wood-infesting pest leaves pinholes and
slender galleries
in sapwood/southern yellow pine, leaving
burrows and area around them stained dark by
the action of fungi? The damage is old, will not
re-infest dried wood, and control may not be
required.
Subterranean termites Which wood-infesting pest leaves NO openings
(or VERY few + sealed over), has extensive
galleries running lengthwise in springwood
which are packed
with hard/masticlike frass? They may infest old
cellulose objects near/in contact with soil.

Carpenter ants Which wood-infesting pest timbers with
extensive galleries that are sandpaper smooth
with rounded edges and contain NO frass?
There may be coarse sawdust found near their
damage.
Carpenter bees Which wood-infesting pest leaves round ENTRY
holes in wood near the side/edge/end that lead
into long tunnels (3-24 inches). The holes turn
at right angles and tunnels run WITH grain of
wood.
