Jerry,

No reputable termite tech would leave those holes open. If it was a termite treatment, they'd be patched.

I think someone forgot the weep holes completely and came back with a masonary bit and drilled them out. Totally useless.

As far as the hole in the side of the beam wall, if it was termite treatment most of the holes would be drilled at an angle and not directly horizontally as it is harder to get a bit through and the chemical to flow in the hole as such.
