Common Wood Destroying Insects Maker

  • Termites

  • Carpenter Ants

  • Powderpost Beetles

  • Longhorn Beetles

  • Flatheaded Borers

  • Wood-boring Weevils


Termites Maker

Major destroyers of wood and wood product materials. Normally associated with buildings, but can also infest wood that has been stored for some time. There are three basic kinds of termites:

  • Subterranean

  • Dampwood

  • Drywood


Isoptera Maker

(termites)

[social insects, winged reproductives with both wings same size and membranous; straight or curved antennae consists of beadlike segments; abdomen broadly joined to thorax; no cerci; chewing mouthparts]


Ant or termite

Termites are sometimes called “white ants” because they are ant-like in form. Termites differ in antenna form and having a broad waist.

Subterranean termite colonies live in the soil from which they construct exploratory tubes in search of wood.


Termite swarming is usually the first evidence of an infestation noticed by most people

Termite Swarming is usually the first evidence of an infestation noticed by most people.


Drywood termites

Drywood Termites infestation noticed by most people.

  • Can live in dry, sound wood

  • Usually tropical and subtropical

  • Kick out characteristic fecal pellets

Carpenter ant damage

Carpenter Ant Damage infestation noticed by most people.

  • Carpenter ants need water

  • Usually build nests in damp or partially rotted wood, but can extend their nests into sound wood

  • Keep lumber dry and properly stacked.


Powder post beetles three families

Lyctids Bostrichids Anobiids


The main sign of powderpost beetles is powdery sawdust. infestation noticed by most people.


Powderpost beetles turn wood to dust! infestation noticed by most people.


  • Lyctid powderpost beetles: infestation noticed by most people.

  • Attack sapwood

  • Attack hardwoods only, rarely maple

  • Require 8% to 32% moisture


  • Anobiid powderpost beetles: infestation noticed by most people.

  • Prefer old woods, 10-20 years old!

  • Attack hardwoods and softwoods including maple

  • Require 13% to 30% moisture


  • Wood-boring weevil, infestation noticed by most people.Hexarthum:

  • Frass looks like powderpost beetles

  • Attack hardwoods, including maple

  • Require high wood moistures, often wet!


Wood-boring Beetle Management infestation noticed by most people.

  • Detect early! (regularly inspect - powder)

  • Keep lumber at less than 5% moisture

  • Keep lumber off of moist floors or ground

  • Resaw to remove sapwood

  • Don’t purchase infested lumber & destroy lumber that becomes infested

  • Fumigate high cost lumber (professionals only!)
