I have applied Bora Care to my shed, but am still seeing little piles of sawdust in places that I cleaned thoroughly.
Bora-Care will take at least 30 days usually to diffuse through the entire piece of wood. This of course depends on the thickness and moisture content of the wood. It starts to work as soon as it begins to penetrate the wood it is applied to. You may continue to see activity in wood that has a prior infestation as Boracare works by ingestion so will only kill the insects that are actively eating the wood and ingest the product. If there are dormant beetles that are not active, but become active later, let's say next year, you could see new activity at that time, but they will die once they start eating since Bora-Care stays in the wood forever. It is common to see activity at a later date since beetles are not all active at the same time.
