Should you be concerned about a bird feeder being close to your house if you see mice feeding and will it attract rats too and will they try to get in to your house?

If your feeder is such that a large amount of seed is falling to the ground, yes it will attract rodents. You can either switch feeders or get a add on platform that catches the seed and stops it from falling to the ground, allowing the birds to eat it and not be wasted. I have added a link below for this type of product for your bird feeder.
