Kill ants indoors...not a great option for those with kids or pets. Keep out of their reach. Combine 1tsp of boric acid with 2 c bait. Mix thoroughly. Put in caps, on foil pieces, in cut pieces of straws, etc where you see ants along baseboards and in corners. Choose bait type dependent on what variety of ants you have. Bait ideas: peanut butter, jelly, sugary soda, corn syrup, 3 tbsp sugar in 2 c water, powdered sugar.
