I have ants all around my house and I don't mean my mother's sisters, I mean the tiny 6 legged little black insect pest type ants. They are in my garden and like to harvest aphid honeydew on my raspberries, which is all together gross. A few have found their way into our house and now that I'm planting a bigger garden it was time to get serious.
I tried over the counter ant dusts, ant traps, ant glue traps, ant sprays, I tried almost every product on the shelf and they weren't deterred or dead.
So I started searching the net and learned about certain plants that repel ants, so I planted pennyroyal, peppermint, lavender, rosemary, and garlic chives. I saw ants on the pennyroyal but for the most part they just walked around the plants to where they wanted to go. Now I don't want to grow a bunch of these types of plants as a border around my vegetable garden because I have very little space to plant as it is.
So I kept looking and found out that cinnamon, citrus oil, lemon juice and cayenne pepper work. I pushed cinnamon sticks into the dirt but that didn't do much of anything. Lemon juice just washes away the minute I water and I have no idea where to get citrus oil.
Eureka! Ant problem solved finally - I put cayenne pepper powder into a jar of vegetable oil, enough to make it a really dark orange / red, and let it stand for 24 hours. When I poured it on the flagstones the ants wouldn't go through the line of oil, it worked like a wall. They'd get close, then just like one of those toy cars that change direction when they hit a wall, the ants turned around and tried to go a different way.
I'm now making a bigger batch of Cayenne vegetable oil to surround my garden's perimeter and to put into the soil where there are a lot of ants. The oil doesn't wash away easily, which will prolong its usefulness.
I wish I hadn't wasted so much money on insecticides since they didn't work.
