Drilling at a 45 degree angle to gain access under the slab as well as trenching?

I am told that I need to drill at a 45 degree angle so as to access the area behind the footer and under the slab. I am sure I can do this from inside the house with verticle holes but with carpet installed that is a no go unless I pull back the carpet which is doable. This 45 degree hole will also be done in areas where trenching is also done.


When using Termidor SC, drilling into the interior of a slab is NOT necessary if you are treating the outside perimeter of the home.  If you are trenching around the outside of the house and drilling through slabs attached to the house, then you do not have to drill interior slabs.  This is clearly stated on the product label.
