Termites: bait stations in concrete

Professional termite companies install the advance termite baiting system around the perimeter of any slabs that may be around the house.  There are concrete port covers that do allow you do place stations in concrete but the holes are large to place the station through concrete.  Some people drill holes next to the house and apply a liquid in those areas to provide a little closer protection closer to the house, but for the most part the stations are placed around the perimeter.
