The plus to boric acid is that it’s a great non-toxic way to get rid of ants. Mix a little with sugar and water, put in an old jar lid and leave in the ants’ pathway.
Day or two and they’ll be gone. Even works with those big, nasty carpenter ants.
I’ll have to try that next time I see ants. I’ve used cinnamon by the kitchen sink before and that seemed to work a little but I still ended up calling in the big guys with the hard chemicals.
