Saltski, we had the same problem at a student house I shared at Uni. I was OK as I was in an upstairs room, my mate wasn't so lucky. We put pellets down around the outside of the house, and a few by the back door on the inside. We used a strong salt solution and shoved that down the sink every couple of weeks, too, in case they were getting in that way. It didn't solve the problem completely, but it did cut it down A LOT.
If you can find out where the blighters are getting in (we think it was under our back door, as it didn't fit very well), then concentrate on that area. I've also heard they don't like black bitumenous paint, so you could try painting some of that on the floor next to the house (unless it would look awful, we have a tarmac drive, so it wouldn't notice - not that you'd need it as tarmac has bitumen in it already). I used to have one or two come into the kitchen every year, until I put a magic mat down by the back door (more for my dogs' muddy paws more than anything else), since that's been down I haven't seen any. I think the going across the fabric bit is too much like hard work!
I might try the fabric. The problem I have I THINK is thast they're living/hatching under the floor as it's probably dirt as the house is 80 years old, then they crawl up the internal walls and come up through the gap between the laminate floor and door frames/skirting etc. I have sealed where possible but they still get through!
I might try the bitumen paint and paint it on the damp proof course, I have been meaning to do something like this because I have seen houses that are rendered like mine with the dark paint on the DPC and they look very neat. I was sucessful with salt at the extremities like doors etc, but am limited with a 1yr old who is learning to walk.
