Should I bore holes every 10-12 inches around my garage for termite control using Termidor SC?

I have a two car garage that is on a concrete slab with a concrete driveway in front of it. I can trench around the outside on 3 sides of the garage. But I am wondering if I need to bore holes every 10-12 inches around the inside walls of the garage next to the foundation or can I bore holes across the driveway in front of the garage?


It sounds like you have a detached garage if you can trench around 3 sides applying Termidor SC.  If this is the case, you do not need to do any drilling inside the garage because the slab should be one solid pour, which means the only way termites could enter is from the outside perimeter.  Also, you do not need to drill across the driveway where the door is either because there is nothing there to protect.  There is no wood, just space where the door is.  The only time you would drill across the front is if you had two single garage doors side by side with a center support.  In that situation you would want to drill just a few holes on the inside near the support, and then outside near the support from the driveway to protect that area.   

If your garage is attached to the house, then you would trench around the outside walls just like in the example above, except that you would only be trenching around 2 sides.  The third side would be against the heated space of the house, where the door is to the house.  You would need to drill this wall inside the garage because you would not be able to trench the other side of it.
