Powderpost Beetles

These small, brown beetles range from ⅛ to ¾ of an inch and can live for one to five years. Outdoors, their life cycle usually completes in a year, but indoors, they may take up to five years to fully develop. Powderpost beetles live and develop inside the wood, emerging only when they reach adulthood, which can make it years before signs of an infestation become apparent.

The beetles go through four stages: egg, larva, pupa, and adult, with the larval stage causing the most damage to wood. Though second only to termites in their destructive abilities, powderpost beetles damage wood at a slower pace and generally don't threaten a home's structural integrity. However, untreated infestations can reduce resale value and spread to other wooden areas of your home.

In New Jersey, the most common type of powderpost beetle that may invade homes is from the Lyctidae family, specifically Lyctus brunneus. These beetles primarily infest hardwoods, such as oak, ash, and hickory, which are commonly used in flooring, furniture, and structural wood inside homes.

Another common invader in NJ is Anobiid powderpost beetles (Anobium punctatum), which tend to infest softwoods, such as pine, and are often found in older homes, basements, crawl spaces, and attics where humidity levels are higher.

Both types of powderpost beetles can cause structural damage over time by boring into wood and laying eggs, which hatch into larvae that continue to tunnel. If you suspect an infestation, a professional pest inspection is recommended.

If you suspect an infestation, inspect for small circular holes in your woodwork. Firewood may also be a potential source if it was recently brought inside. For a thorough inspection or more information, contact the professionals at Ozane Termite & Pest Control to request a free evaluation.
