The Timbor needs to dissolve in the water.

The beetle larvae emerges from the wood in spring, grows into an adult during the summer, then, in late fall, returns to the hatchery (same wood it came from) and lays new eggs. Knowing the life cycle can often help determine when an infestation occurs and where it originates from.

In that news link, if that home owner purchased the flooring during the summer and the larvae emerged the following spring, then the infestation was already in the wood/flooring, when purchased.

If you buy infested wood, those hatched bugs will come back to the same wood and repeat the life cycle with the next generation.

The adult insect has wings, it flies. An infestation does not start by flying to your property. The adults return to where they hatched from, they don't fly to new places. The way an infestation moves/migrates is by infected wood being moved to a new location. The only time wood is infected is when the bug is in the egg and larvae stages.
