Many properties are sorrounded by concrete paths or aprons. This requires further extensive treatment. Ideally the pest manager should cut away the concrete around your building and flood the soil as we described previously.
Of course this is difficult and expensive to do, so usually the pest manager just drills holes through the concrete, and then injects chemical through the holes which are later sealed up. The manufacturers advise that these holes need to be drilled every 150 -300mm. That's a lot of holes and a lot of expense for you. So again some companies drill fewer holes and you get even less of a treatment, since there are gaps remaining for termites to get through. This means your home is not properly protected and you are wasting your hard-earned money. As you don't know what is underneath the concrete, you don't even know where the chemical went. Trials have shown the chemical often doesn't travel very far!
