Ok, this is embarrassing but maybe y'all will have an answer.I've caught, in regular wood/spring mouse traps, a few mice in the cab over the years. Never understood how they got in.When I replaced the A/C evaporator and heater core, they were full of shredded paper napkins and signs of mice. I cleaned it all up and glued (5-minute epoxy) aluminum screen over the air inlet to the box, where it meets the cab sheetmetal under the windshield. And everywhere else that anything could get into the box. I guess they could chew through the screen but there is nothing in the cab so attractive to prompt that, except it is warm and out of the weather.I caught another mouse in a trap the other day, so they are still getting in. I dread taking the dashboard out again.Any ideas how / where they are getting in? This morning the trap was sprung, bait gone, no dead mouse - so they are getting too smart for me. I feel like Elmer Fudd.Any and all ideas are welcome. Thanks.Regards,Andrew
