Anobiid Beetle Emergence Holes

Anobiid Beetle emergence holes plus "Pick Holes"
Anobiid Beetle emergence holes.

These holes show where Anobiid beetle have emerged. (The inspection pick holes shown is the wood pried open showing the fecal pellets underneath.) This assures the Anobiid beetle is present.  Anobiid beetles will use the same holes in which they will lay eggs.  The Anobiid beetle is the only wood destroying organism that does this.  The true powder post beetle will emerge then seek other wood in which to infest.  The Lictid beetle usually infests hardwoods.  The Anobiid beetle usually infests softwoods.  The wood infested is usually the subfloor, joists, stringers or posts under the structure.

“Powder Post Beetle” Anobiid Beetle

If Anobiid beetle infested wood is found in your house by an Inspector, it is always better to remove the wood and replace it with noninfested wood, preferably with pressure treated wood.  Then treat all of the wood with Tim-bor or other Borate containing material to kill the larvae of the beetle or to prevent the beetles from reinfesting the wood.   A 15% solution, of borate,is required for a one coat application.  To get that percentage of Borate it is necessary to use warm water when disolving the Borate.  Using water as it comes from most faucets on the Peninsula will only yield a 9% solution.  We include a surfactant in the mix (Profoam) which causes the solution to foam up when it is sprayed onto the wood.  This causes the solution to “stick” to the wood rather than running right off.  When carpenter ants are a problem we also include a pyrethroid in the solution to control the carpenter ants.  Doing the job this way costs more money, but as far as we are concerned it is the only way to do it.  You only have one chance to do the job correctly.  We believe in doing the job the best way we know how as it is the only chance to do it.  The Borates are salts and will stay in the wood forever.  It will never need to be done again.  Doing the job right the first time is our goal.  Call us at 457-4341 or 1-800-828-5508 and give us a chance to bid on your job.  Read older entries on this subject by going to the bottom of the page and clicking on older entries or go to the Catagories column at the right hand side of this website.

Wood Boring Beetles

The beetle that causes the most damage on the Olympic Peninsula.  These beetles are known as Anobiid beetles.  They usually emerge in late July or August.  It is very unlikely that you will ever see the adult beetle.  By September the adults are gone.  What is seen is the emergence holes in the timbers or structural wood.  Read the rest of this entry »
