Though these powered, double door squirrel traps were designed primarily for gray squirrels, red squirrels and chipmunks they will take even smaller rodents like voles and even mice. Above is a small flying squirrel left and a vole right. With tight closing doors and 1/2×1 mesh, we have received pictures of mice in these traps, which means that the traps will take just about any rodent that will fit in them or trip the trigger.
