the guy who sprayed around my house left me those little traps where the ants eat the bait and then take the food back to the nest which wipes them all out.
for the mice set traps.... leave a dish of bird seed in a corner with white flour sprinkled on the floor so you can see the evidence of tracks. there are also those electric shrill sounding (to a mouse) noise makers that drives them out without the worry of a cat ingesting a poisoned wobbly mouse and getting ill.
the rule of thumb with critters...is: if they can get their head thru a whole than they can get their body thru it also.
(size of a nickel.) Find the hole's and plug them....
sometimes copper mesh is used as it stuffs in a hole real easily and they can't chew it.
become the godfather and make them an offer they can't refuse.
