I talked to an exterminator, and he said to use the bait boxes with the bigger block of bait in it. Place them at the openings of your building, garage doors, service doors, both inside and outside. Do not use the pellets. The mice can carry it to there home (usually in your seat or headliner) With the bigger blocks they have to chew off a piece , but can't take the whole thing.
