Tim-bor Professional is an insecticide, fungicide and wood preservative for the protection and treatment of lumber against fungal decay and wood-destroying insects. However, is not to be applied to any live trees. Depending on the type of borer being treated, you can look at using a product like Dominion 2L. When using Dominion 2L Termiticide for borers, it is labeled to be applied as a soil injection which includes grid systems, circle systems, basal systems, and soil drench applications.
Tim-bor Professional would not be recommended to treat any active infesations of wood boring insects as it only penetrates up to 1/4 inch. It will also leave a white residual behind. In most cases if a wood destroying insect is found within the frame of a piece of furniture your options are as follows:
Option 1- Strip down any stain or finish on the wood down to its raw natural state and apply a product like Boracare to the raw wood surface and then you can refinish as desired once dry;
Option 2- If stripping the finish off isn't an option then you would need to drill holes in the needed places of the furniture and insert a product like Jecta. Both the Boracare and Jecta absorb into the wood so that as the insects inside it eat the treated wood they consume it and die from it. Both products also last for the life of the wood to protect it;
Option 3- If neither of those are an option for you then you would need to hire a company that has a heat treatment or fumigation treatment chamber to put the furniture within to kill all the insects within it without doing any damage to the item.
It is recommended that you use a sealant or paint on the wood treated with Timbor. This will seal the product into the wood so that it will last for the life of the wood. It is not necessary to paint or use a sealant though.
The manufacturer states that Timbor will last for the life of the wood as long as the wood is not exposed to rain or flooding. It will stay in the wood forever because of how it bonds to the cells of the wood.
