Mouse problem - advice re traps

6 dead mice so far.
Jen nearly made us move to a hotel last night!
Destroying their nest clearly made them spread out and most of the last few kills have been very small just weaned mice so hopefully most are either dead or will depart for pastures new.
Setting the snap traps is incredibly fiddly and i've got a few blood blisters to show for it.

My terriers seem to keep the rats/mice away. I don't have any issues, despite living in a wooded area, and having dog food, cat food, rat food etc etc etc out in bags. I have cats too, but they are useless lazy buggers. The terriers live for the day my rat colony makes a break for it. Until then they have to be content with attempting to find wild ones.
Of course.. I don't have squirrels to watch anymore either.
