I wonder if anyone can offer any advice on getting rid of ants from my potato bags? We've recently had astroturf installed & the ants have pulled loads of sand up from underneath it, and have now decided to move into my potato bags nearby. Obviously because it is food we are planning on eating, Im a bit wary about what I can use. Any suggestions? Ive tried flooding the bad with water and chilli powder mix, but havent seen any results.
