Powder Post Beetle Pest Control
These little pests are most likely encountered by homeowners during the purchase and sale of their homes. Like termites, they can do a lot of damage without ever being noticed until, one day a professional inspection is necessary and their presence is discovered. Small holes in a wood beam along with a fine powder appearing on the floor or in a crawlspace below are common indicators that they are at work in your home or business. If either of these indicators are present in your home or business call for a free consultation and estimate.
Powder post beetles lay their eggs in cracks of wood and the larvae tunnel into the surface, filling it with a very fine powder-like dust. Powder post beetles have long, narrow, flat bodies that allow them to easily attack wood surfaces. These beetles are reddish-brown in color. There are several hundred species of powder post beetles, but fewer than 20 are widespread.
Powder post beetles can emerge from wood used in construction from one to 10 years after a structure has been built, usually in the spring. They are most likely to be found in softwoods (pine, spruce, fir) or certain hardwoods (oak, maple) frequently used for construction, including wood used in log homes, conventional homes and furniture. These beetles are attracted to lights or to windows.
Where they may burrow small, one-eighth inch round holes in wood, and larvae create channels where they have chewed their way through. There is usually a fine sawdust-like powder streaming from exit holes.
Their life expectancy is between one and two years.
Some researchers believe that powder post beetles are second only to termites in the United States in their destructiveness to wood and wood products.
Adult powder post beetles are very active at night, enjoy flying and are attracted to the light.
Powder post beetles often attack hardwoods, and can be found in hardwood floors, timbers and crates, antiques and other objects made of hardwood materials.
Treatment and Customer Preparation
Graduate recommends treating the infested wood with a borate material that easily penetrates the surface and is absorbed into the wood where the destructive powder post beetle larvae are feeding. The product kills the larvae and prevents the re-infestation of the wood.
Preparation will vary depending on the areas affected. Therefore, necessary preparation will be determined at the time of quote inspection.
Powder post beetles prefer wood with a high moisture content of 20% or more. They are most commonly encountered in the basement and/or crawlspace areas of a structure. They can be prevented with proper ventilation and/or dehumidification of these areas. If an area of your home/building is susceptible to infestation than vigilant inspection of wood sources may be necessary.
