You should leave it place if properly applied since dusts are for areas where you can't touch (and consequesntly where the roaches live) unless you eliminate those areas by other means such as proofing (sealing to exclude) cracks, etc. with silicone etc. Remember borax does not break down nor is it repellent, but it's good protection from a reintroduction if you can leave it alone.
