I tried baking soda and corn meal... they weren't going in the traps anymore, ended up with putting bait out. Still took a couple weeks before I started finding dead ones.I have been battling mice. Bait works to some extent but there are still some mice. None in the house just in the garage and barn. Watching home remedies. Seems baking soda and flour are popular as is flour and plaster of Paris. I mixed some yesterday and again today. Trying both recipes. The mice ate some last night. Skeptical of home remedies but worth a try.
