Waterbugs

I had a friend call over the weekend about a cluster of waterbugs he found up in the joists of his home. He essentially found a pocket or a nest of the Oriental Roach and he was wondering how he should proceed. Usually with a waterbug problem I recommend a inside perimeter spray and baiting with Niban or some other kind of Baygon type bait. This time I told him to just get a good premixed spray from Home depot and spray the heck out of them. Half the job was done in finding the pocket of them, now killing the bulk of them will eliminate the problem. As always I told him to use caution and to warn the wife that there might be some strays that got away and retreated from the "waterbug killings". Anytime you can find the source or nest it is a good day.
