I just noticed a hole on the inside of our one-year-old new cabinets (oak). I knew something had been “chewing” in the corner of the wall before the new cabinets were installed. Now, I have found these holes almost everywhere. The inside of the cabinets are not finished. Would staining or painting them stop them? So far, only two have appeared. I had an exterminator spray them with a dry power of some sort with a long tube, that’s how I found what was doing it. How can I stop them from ruining these cabinets and antiques in our home? Thank you.
I suggest you read through our POWDERPOST BEETLE CONTROL ARTICLE so you can better understand this pest. In the article you’ll learn what it means when you find the holes you’re finding. You’ll also learn about the various treatment options that can handle the problem. This information will help you to decide if you wish to tackle the problem yourself or have a service company do the work for you. As you’ll see, it’s not hard to do and since doing it yourself will insure you get enough product applied, this approach can many times be the best option.
In our article you’ll learn this pest is “wood specific”. This means it will tend to focus on the wood type where you see activity. So unless you’re home has similar wood and the wood is untreated (not painted or stained), there is little risk of them moving from the cabinets to the home. However, paint and stain alone won’t save the cabinets.
In order to save the cabinets which now show activity, you’ll need to treat with either the BORACARE or JECTA GEL we have listed in our article. These products will penetrate the wood and get deep enough to kill all the larvae which are really the problem. You see, the exit holes are from where adults have emerged and though you can treat these voids, in most cases they’ll be abandoned and not important. What is important is the rest of the wood because no doubt there are many more larvae still active inside the cabinet wood and it’s these guys that actually chew and eat cellulose (not adults that emerge). So in the end, you need a product that will penetrate through and through the wood so as the larvae eat, they’ll ingest some of the treatment and die. In the end, it’s this that will break the cycle and end the infestation.
The good news is that you state the inside of your cabinets are untreated (unfinished wood). If that’s true, it should be easy to coat the area with Boracare and get the cabinets protected. I recommend giving it at least 2-3 coats over one day to insure you get enough applied. Within a few days the product should penetrate through and through which will kill all the larvae and take care of the problem.
At some point in the future you could opt to paint or stain the wood but since doing so would make it near impossible for the Boracare to be used again, I’d recommend waiting a good 6-12 months to make sure you don’t keep finding exit holes. Once the holes stop for at least a year, finishing off the wood can be considered an option. But to make sure you can still treat it should the problem remain active, leaving as much of it unfinished is the best thing to do for now.
