Food and water are to 2 key items mice look for and need.. Most poisons are about worthless,, as I have seen piles of po,, that are blue or green,, ( the same color as the poison.. By the size of the piles of po, and the amount of poison ate,, it just does not work any more..
I know this is not right by laws and tree huggers,,, but it does work..!!! Good old green anti freeze.. Just a little in the bottom of a plastic bottle cap,, or lid seems to work better than anything else I have found.. Some feel its the sweet taste,, others say its just wet.. Who cares as the amount of damage and hardship mice can do to a stored combine,, tractor or Airstream can be costly,..
Just make sure they are put somewhere that pets,, and grand kids can find..
