If the windowsill in question is NOT one that your ferrets, children, or any other household animal are likely to sit in, then I have a suggestion. I learned this from my grandmother, and it *really* works! Sprinkle Comet Cleanser (you know, the scrubby powder cleaner stuff that turns blue when it gets wet?) on the windowsill. The ants will *not* cross that line! They stay on their side, you stay on your side, everyone's happy. I have done this for years and I never have an ant, except for the ones that my children bring in as "pets." Now if I could just find such a solution for fruit flies...<sigh!> Chana & Co. 6 Kids, 3 FurKids, 1 mangy excuse of a ferret-hating cat, 1 neurotic rabbit, and a parakeet named Chompers. <<have you hugged a ferret today?>> [Posted in FML issue 3461]
