Powderpost Beetle Damage
Powderpost beetles are wood destroying insects that are found all over the world. They wreck havoc on a homes wood structure and are second only to termites in the amount of destruction they create. Powderpost beetles can also be very active for many years before a home owner is alarmed of their presence.
Anobiid powderpost beetles are a common subspecies that attack both hardwoods and softwoods. Other types of powderpost beetles prefer only hardwoods, such as cabinets, furniture and flooring. Anobiid powderpost beetles can be found throughout a home, but are most commonly found in the crawl spaces.
Powderpost beetles need really damp wood with a moisture content of at least 14% to survive. Damp crawl spaces, like we have in South Louisiana, provide an ideal environment for the beetles to breed and multiply. Evidence of powderpost beetles are usually found on the wood beams, floor joists and sub-flooring.
Powderpost beetle damage closely resembles “shot” damage from a shotgun. The holes are usually slightly smaller than the hole left behind from a BB, which is normally between 1/16 to 1/8 of an inch in diameter. There may just be a few holes or very many. If the powderpost beetles infestation is active, you may also see powder coming out the holes or sitting below the holes.
Powderpost Beetle Treatment
Finding powderpost beetle damage on an older pier home is very common in South Louisiana. In many cases the home has been treated in the past and there is no longer an active infestation. Unless there was substantial damage caused by the powderpost beetles, there may be no need to worry. If the powderpost beetle infestation is still active, having the home treated as soon as possible by a licensed pest management professional is important.
The type of treatment required to rid your home of powderpost beetles varies depending on the location of the infestation, the size of the infestation and the exact type of powderpost beetle found. While chemically spot treating certain areas of your home may prove successful in some cases, putting a tent around the entire home and fumigating may be the only viable option. Fumigating an entire home can also be very costly, but if ignored a powderpost beetle infestation can cause significant structural damage to your home.
