The first evidence of an infestation is usually very fine sawdust on or beneath wood and small holes, 1/4 to 3/8 inch in diameter where mature adult beetles have emerged from the wood.The powderpost beetle normally enters homes through unfinished lumber or wood products like furniture or paneling. Larvae are 1/8” – 5/16” in length and are creamy white in color. Like termites, some powderpost beetles will feed on hardwoods — such as oak, ash, walnut, bamboo and hickory — and softwoods like pine. True powderpost beetle frass is light and powdery, whereas the frass produced by other beetles is grainy.Infestations limited to a single object or a small area can be eliminated by removing the infested wood. There is no known health threat from powder post beetles. For more on this topic, seeFor borates to penetrate the wood surface must be unfinished; the spray will not penetrate paint, polyurethane, or other water repellent coatings. The consistency of the frass helps to determine the specific type of beetle present in the wood.

A microscope or other means of magnification is necessary to see this characteristic. Once the adults emerge, they can re-infest the same wood by laying their eggs on the surface again, and the cycle continues. Powderpost beetles require the moisture level of wood to be above 12%. And yet, customers often receive conflicting opinions about whether the insects and/or damage they are seeing is indeed due to powderpost beetles. The head features a pair of short, clubbed antenna, which distinguishes the powderpost beetle from other beetles of similar size and shape. These beetles have six legs, are reddish brown to black and usually 1/32 to 1/4 inches in length. Lyctid beetles are reddish-brown to black in color, and about 1/32 to 1/8 inches long.

As a result, infestations are seldom obvious in buildings less than 10 years old. Although lyctids sometimes infest firewood, this is seldom the reason other materials become infested within a home. Although bostrichids seldom re-infest wood after the first generation emerges, extensive damage can occur the first year due to a high initial population and rapid development.

Infested items are placed under tarps or in trailers or vaults to maintain gas concentration at the proper level.

The largest powderpost beetle infestations usually result from using wood that was improperly stored outdoors. A “wait and see” approach often makes the most sense, especially when there is uncertainty whether the infestation is active. For this reason, the products have limited use for treating infestations within the living areas of homes. TO IDENTIFY A SPECIFIC WOOD BORING BEETLE CLICK HERE. Conversely, as wood ages, starch content declines and development slows to the point where some beetles may not emerge for two or more years if at all. (For more on this pest, seeAnother way to confirm that an infestation is active is to mark or seal any existing holes, sweep or vacuum up all powder, and recheck the wood for new holes and powder later on.
