Get Rid of Ants - Finally I Found the Solution to My Ant Problem

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.
