My mom emailed that they had a parade of big ants in the kitchen, and she found an article that suggested the following remedy: Wash down counters or table with half and half solution of water and vinegar. Then sprinkle paprika, chili powder, cayenne, bay leaves, cinnamon or dried peppermint. Put bay leaves in your cupboards. Apparently the paprika combo worked well, although apparently my dad found it to be a rather tempting flavor mixture. A brother-in-law then replied with another, even better, suggestion: Keeping a large nest of spiders in the kitchen works well too.
