Ants are welcome to be in the garden as this is where they belong, however, when they invite themselves in it can be rather annoying. You can either go to the shops and buy some poison which will not be so great, or you could try the idea below. I have tested this myself, and my last ant incursion was stopped in its tracks.
- Eucalyptus oil or tee tree oil
- Cotton ball
Ants invade for 2 things, water and food so try not to leave these about as an open invitation. Once these have been cleaned up then soak a cotton ball in eucalyptus oil and run it across the door or window where the ants are entering.
Ants use chemical trails to find their way about. If you remove their need to come in and remove their chemical road, you will be a long way to solving your uninvited guest problem.
