I would put borax under the mostly harmless category. I'm told you have to eat good amounts to get a stomach ache.
check that of course.
I wonder if it was cassia, not cinnamon. They are sold under the same name.Kisal wrote:I use boric acid mixed with either sugar water or peanut butter, whichever they seem to go for at the time.
I tried sprinkling cinnamon, and -- I kid you not, folks -- watched the ants come en masse and carry it away with them! It was just grocery store cinnamon (McCormick's, I think), but I'll be darned if I'm gonna buy them the gourmet kind I see at the specialty store!
Why don't you just bake them some cornmeal bread? Well, the pepperming oil doesn't fit, but the ingredients are pretty close!What if we mixed the cornmeal, and powdered sugar with the baking soda, and maybe a touch of cinnamon, with peppermint oil to hold it on an index card
IMO, the ants would be drawn to those substances. What does work, though, is ordinary white chalk. (Actually, any color would work, but colored chalk often leaves stains.) My grandmother used to draw a chalk line around every window and along every exterior door sill in our house every spring. We had ants all over the place outdoors, but nary a one inside the house. (I used to laugh at her chalk lines, but I was a smart-alecky brat of a kid. )Ozark Lady wrote:I have also heard that ants won't cross lines of white flour, white sugar, or orange peels, not sure it is so. And not so sure that I want those on my window sills to keep ants out either.
