CTX 108 and Ultrakill Timberdefence are options. They are very similar products and in a solvent that is highly flammable though. Although the label allows for spraying, I really don't recommend using that method of application due to the increased fire hazard and only apply in a well-ventilated area.

I'm also a little concerned about your use of the term "for wood borer". If the timber is already infested, applying liquid pesticides may not actually solve the infestation problem. Coatings are more preventative than curative...
