We had a water leak under our kitchen sink and got German cockroaches -the first time we'd ever had a roach problem. I used borax-sugar for about three weeks with no benefit. DE took care of the problem within 3 days. I put it down and left it down for about a week before cleaning it up. That was 4 years ago, and we've not seen a roach since.
