In the floor? Common in the (block) walls, either on the inside and/or the outside, but we (as a company) hardly ever drill a floor. And if we do, it's usually only in one or two spots, certainly not a continuous line, I can't think of any instance where we would ever do something like that. Sometimes we do have to drill block walls, mostly to get to the voids inside. Termites will use this way to get inside without being seen.
And don't forget, it might not have been an actual exterminator that drilled all those holes. Might be any one of the homeowners or any number of other people, for any number of reasons. I've seen some strange things over the years...
But I don't think I'd worry about it if you haven't had any (water) problems by now, so yes, you can seal them off. Use concrete, stuff something down there first so the concrete won't fall thru.
The next time you need to worry about termites is probably the next time the footprint of the house is altered. Have new foundations of additions treated during construction.
