There are several web pages on the internet to validate my claim that dried molasses sprinkled on the ground will kill ants. Articles on the internet say it works only for fire ants, but I've been using dried molassas around my home(s) for many, many years and it rids all kinds of ants for me; big ones, little ones, black ones, brown ones.
Dried molasses is a horse feed supplement, designed to be mixed with horse feed as a sweetener. It won't hurt any animals, birds, people, or anything, but is deadly to ants. Sprinkle it generously around your camper, on top of ant hills, and even fill bottle caps with it and put it under your refrigerator or on your counters wherever you see ants. The ants carry it back to the nest, they eat it.
Ants are exo-skelletin (hard shelled). The ants eat the dried molasses and then it expands inside them, literally blowing them up killing them. It IS very efective. I purchase it in 50 pound bags from a local farming elevator that supplies animal feed to farmers. A 50 pound bag can be used up very quick, or may take years. As the years have gone by, I've had to use less and less. None inside the house any more, and only occasinally in the yard now when I see a new ant hill when mowing the grass. My last 50 pound bag has hung around for 3 years now, and I still have plenty left. Initially, I ran through a couple hundred pounds, sprinkling the yard like grass fertlizer. It worked, kills the ants. Birds got fed, dog loved rolling around in the grass, and my bare feet smelled sweet! (It has a really nice smell). Most important, ants disappeared... almost completely on the acre I live on!
Wet molasses will not work. It has to be dried so when it gets wet, it expands.
