5 DIY Powderpost Beetle Elimination Tips for Homeowners

There are certain issues that are of serious concern to most homeowners. If you discover that you have a cracked foundation, a leaky roof, or faulty wiring, for example, you know that there is going to be some major expense involved in repairs to make sure that your structure is safe and livable. And at the top of the list for scariest discoveries that could damage your home might be termites, which could leave your structure in need of tenting at the very least, and condemned at the worst. What you may not know is that termites aren’t the only pests that like to chew on wood, leaving it riddled with holes and compromising the structural integrity in the process. In fact, there are a variety of beetles that can do similar damage. And although powderpost beetles are best known for infesting deciduous trees, eating the starch and leaving their powdery frass behind (hence their name), they will also attack wooden surfaces in your home, including flooring, cabinetry, and framing, along with furniture and any other wooden objects you might have. So you’ll definitely want to get rid of them as quickly as possible. Here are a few elimination tips that will soon have your home free of powderpost beetles.

  1. Preservation techniques. Whether the wooden surfaces in your home have been pressure treated or you decide to use chemical preservatives on them after the fact, you can use such measures to help protect your wood from a powderpost beetle infestation. And while this method might not be viable if these pests have already found their way into the framework of your home, it may be useful for other interior surfaces.
  2. Bora-Care. This alkaline salt product is not to be confused with Boric acid, which is sometimes used to kill pests like termites and cockroaches. Bora-Care, on the other hand, contains disodium octaborate tetrahydrate. When added to water in a 1:1 mixture, the borate salt becomes a solution that is deadly to many pests, including powderpost beetles, but is nonetheless safe to use on wooden surfaces (and probably much safer for the human and animal inhabitants of your home). Just keep in mind that application directly to wood surfaces will only work if you have exposed wood, so if it is painted or varnished you might have to sand it down or drill holes to inject your product with a special needle.
  3. Diatomaceous earth. This naturally occurring sedimentary rock is made up of fossilized diatoms (a type of algae) and it is crumbled to create a grainy powder that is deadly to insects with exoskeletons as it absorbs the waxy layer on the outside of their shell, causing them to dehydrate and die. What is most appealing about this natural insecticide, however, is that it is not harmful when consumed by humans and animals, unlike chemical pesticides. But it can be hazardous when inhaled, so it’s probably best to keep it away from kids and pets.
  4. Fumigation. Although this is what most people would prefer to avoid, you may have no choice but to gas the pests in your home in order to ensure that you kill them all, including eggs, larvae, and adults in one fell swoop.
  5. Wood removal. You’ll probably want to try approved Powederpost Beetle Control Treatments and Spray before you resort to removing wooden surfaces from your home, but in some cases this option may be preferable to fumigating, depending on the scope of your infestation. Sadly, this may not entirely eliminate powderpost beetles, so after removing affected wood it’s probably a good idea to fumigate anyway.
