My daughter has had an ant invasion in her home. She has been fighting a battle with ants since they bought their home. They now believe the home was built on a large ant hill. Most times she is able to keep control of the ants by vacuuming daily. The ants seem to come in looking for food or just to get in out of the weather. We did some research looking for a natural non-chemical way to get rid of ants. With a toddler in the house we wanted to be very careful. We tried a few and the one that seem to have worked fairly well is putting cayenne pepper at entrances and along ant trails. What does an ant trail look like? I don't really know but I figured if I put it along the edges of the wall near the windows and doors that would be where the ants might walk. What I understood the ants will not walk into the powder because of the smell.
Warning when using this method be careful not to get the powder in your eyes and wash your hands immediately after working with the cayenne pepper. Do you have a natural ant repellent that has worked for you?
