Understand that bringing the feed in at night helps but it also means the rodents just feed during the day. And the pepper, I've talked to a dozen people that tried that before they ordered a feeder. But good luck, we all hope you are successful.I appreciate your post, and know I need food improvements. I do not like the treadle feeders - I have had two different types. I find them difficult to clean and a perfect breeding ground for mycotoxins. I am going to go with something homemade. I am going to use Tupperware containers elevated on feed stands that are on boot trays. Then I am going to seal shut the containers at night, clean up the spillage and then double ensure by sprinkling cayenne pepper. I will let you know if this works.
