Best advice is, block all points of entry.Many years ago,I went around my home, closing various nooks and crannies where cold draughts were coming through.A few years later, when all my neighbours had to call Rentokil after mice invaded their homes, . . . I was the only one unaffected.They only found mouse poo poo after they checked behind the bath panel.I still hear mice occasionally, but they can't get in.Try, wire wool, pieces of wood, shaped to block holes, etc.I bought some cork expansion strips, brilliant for filling gaps under skirting boards.Your home will be warmer as well.
