mahogany veneer cabinet with beetles

We have discovered powder post beetles in a corner Mahogany veneer cabinet.
A gift from a friend of a carved eagle head was the apparent culprit. We have moved the cabinet outside to our patio porch.
The shelves are unfinished on the bottom but fixed and the back is unfinished.
We think the Timbor would be the easiest to use since the wood involved is 1/4 inch plywood veneer?
Our local services all claim fumigation as only cure?

If you read through our POWDERPOST BEETLE CONTROL ARTICLE, you'll learn there are two main products we recommend for use on wood. TIMBOR is one of them. But the main limiting feature of this product is that it doesn't penetrate the wood. Timbor is best used as a preventive product since it will lie on the surface of treated wood keeping damaging insects and algae at bay. But if you have an existing problem, the BORACARE is clearly what you must use as we discuss in our FURNITURE TREATING SECTION of our article. Boracare is the only product that will penetrate the wood through and through thus insuring you get all the feeding larvae. Since the wood you've described has an unfinished side or two, it should be easy to effectively get it treated.
