“Rob showed me signs of Powder Post Beetles in my basement rafters.

I built my house in 1978 here on the east side. I have had the same Pest Control the entire time every 3-4 months. With the exception of getting a new bug guy every other service I have been satisfied.

I started to get some sagging in one of my  hardwood floors and some funny looking marks so I called a contractor and he recommended an Exterminator. I called my bug company and they said it was termites so I paid them $1,500 to treat it. After I was online and saw pictures of termite damage and the dirt inside of it I remembered what my damage looked like and this wasn’t that.

This is when I called Cobra Pest Control. Rob looked at the old boards that were reinforced with new wood and said that it was powder post beetles and no evidence of termite damage. Rob said that the bugs were probably in the wood when the house was built and it should have been identified. Years ago. He also said that the termites I paid $1,500 to kill was not necessary. ”

Biology and Behavior

What is a Powder Post Beetle?

Powder Post Beetle is a small Wood Boring Insect which will reduce wood to a fine powder. Powder Post Beetle Damage is done by the larval stage as they make narrow tunnels in wood as they feed.

What do Powder Post Beetles look like?

Beetles a very small about 1/8.” They can be reddish brown to black. You are more likely to see damage than the beetles because the adults are short-lived and are active mainly at night. The larvae is a small grub like worm, 
c-shaped and cream in color.

Are Powder Post Beetles Dangerous?

Powder Post Beetles themselves are not dangerous but the damage they cause could be if extensive enough to cause Structural Damage. Most Powder Post Beetle Damage is found in older hardwoods. Even with half the beam gone it is probably still stronger than the soft pine used today. But I am not a Structural Engineer.

What are the signs of me having Powder Post Beetles?

Two signs of Beetles would be small Pin Holes on the surface of wood and a powder like pile below the wood. This substance is call Frass and many pests create frass so let a Professional Exterminator determine what you have.

How did I get Powder Post Beetles?

Powder Post Beetles are introduced into buildings in lumber, old furniture, paneling or flooring. Wood may have been improperly stored or dried. Many houses have lumber that was milled before wood was treated. Powder Post Beetles can fly in from surrounding areas.

How can I rid my house of Powder Post Beetles?

Powder Post Beetles damage wood slowly so you have time to decide on the proper plan for you. Powder Post Beetles will only lay their eggs on bare, unfinished wood. Wood which is painted or sealed will provided less surface to infest and lay eggs. Controlling humidity levels is important. You can go so far as to replace infested and damaged wood. Two treatment options would be one Fumigation, this is very time consuming and expensive. And two surface treatment, this is the most common approach and affordable. Rob can explain all that in detail.
