We have slab floors in Southern California
We have had subt. termites build tunnels in the garage, trying to get into
the wood structure. They were easy to get rid of by drilling holes in the
garage floor and injecting poison.
Yesterday we noticed a mud tunnel next to a baseboard in the hall in the
center of the house.
How do we drill holes in the slab without hitting a water pipe in the slab?
How can the termites get to the center of the house, covered by a slab? What
is the best way of dealing with them?
Of course, we will have to deal with a pest control company but it would be
nice to know about potential alternatives before we get involved with them.
Can we get rid of them by trenching around the house and poisoning the soil
on the outside of the foundation (footings)?
Thanks for any input
