I have found glue traps and live traps to be utterly useless – never caught anything with those.
Most successful have been these – they are awesome and much safer to arm and place (don’t snap on your finger easily). (http://www.amazon.com/Ortho-0321110-Defense-Press-2-Pack/dp/B003YL4MG0/ref=sr_1_9?ie=UTF8&qid=1360967290&sr=8-9&keywords=mouse+traps)
followed by the classic wodden ones (http://www.amazon.com/Victor-Easy-Mouse-Trap-M038/dp/B000HJ79Y4/ref=sr_1_6?ie=UTF8&qid=1360966979&sr=8-6&keywords=mouse+traps)
as bait I am using peanut butter in some and cream cheese in others – seems mice have different tastes! key is replacing every day as they like their bait fresh. and just don’t leave any other food lying around or just in bags. Good luck! I know plugging the hole is ideal but our house is big and old with many little open under-door cracks etc – I’ll never seal it up completely. and to find the hole in our kitchen I’d have to rip out all built-in cabinets… just not an option right now.
