There are two options for such a small icon. The first would be to inject it with some Baygon Aerosol through any cracks or seams in the metal cover. If you don't think this is going to reach deep enough into the wood icon, drill some port holes through the bottom and treat it from this side. You should be able to get good penetration and coverage with the aerosol alone. If you still have activity 2-3 months after treating, you'll need to get some of the Jecta Gel and inject this through access holes on the bottom that can be drilled if needed. The bottom line is you must get this wood treated through and through if you want to kill off the feeding larvae as explained in our Powderpost Beetle Control article.

There is no risk to people, the wood or the local environment if you were to treat it with the Boracare we have listed in our article. When mixed and applied properly, there is no odor and once left to cure (46-72 hours) the wood will keep it's look prior to the treatment. Using Boracare will not affect this wood whether used for molding, furniture or firewood. It uses Boron for the active ingredient and these products are both safe and yet effective for certain pests like powder post beetle larvae. If you wish to protect your future creations, I suggest treating most any wood you intend on using for furniture. Nothing can be more humiliating then to have emerging beetle larvae coming from a finished piece which took endless hours to create. Don't risk this happening; treat the wood beforehand – especially any good quality costly hardwood stock – to insure it will remain intact for many years to come.
