woodworm in joists in my kitchen

We moved I to our house three years ago and have just started a renovation of the kitchen. After pulling up the tiles (that were laid directly onto the floorboards) we were having to replace the floorboards anyways but there's extensive woodworm damage to the floorboards. There's a large area of approx 3mx2m of extensive damage and then sparingly it comes to an end. We've knocked through to the dining room and the floorboards there and the hallway all appear totally fine. There's a few joists that have evidence of woodworm holes along the top and the odd holes in the sides bear to the top of the joists. The first year we moved in I saw several woodworm, my husband said I was mad but I knew what they were and I knew they were coming from under the sink. After he pulled off the kickboards there was about 20 dead ones on the floorboards. Anyways! I made him take up the full kitchen floor as the builder wanted to self level over all the old tile adhesive but I just thought the problem was more than the floorboards and worse than the builder was making out. My husband said the floorboards are still sound so we've treated them ourselves with the professional concentrate stuff. I'm just concerned, is this enough? Can they come back? There was loads of dead beetles on the foundation floor and LOTS of frass all under the floor. The plumber lifted up a few floorboards under the dining room and we had a peak in and the joists there seem fine?? I'm making my husband take a few of the boards up in there so we can treat that too but I'm just worried about the joists and the rest of the house! In the back bedroom there's some holes on one floorboard but they look old and there's no evidence of frass around it and the holes aren't spread out (as in they don't span a wide area) Any help would be great. I'm going woodworm mad!!
