You have to be careful with wood treatment fluids these days. I haven't bought any recently, having stocked up with the old formula solvent-based Cuprinol 5 star just before it got banned, but for traditional plywood (other than marine ply) plywood you really do need to use a hydrocarbon solvent-based product. No only does it have superior penetration than water-based products, but water-based products can result in delamination and warping of plywood when drenched sufficiently to treat an infestation properly. The last time I looked, the Rentokil stuff was still solvent-based.
