Herb to deter ants
I read in this forum about Costmary being used to deter insects (inc ants). I have a bad ant problem in my veggie garden and would appreciate any recommendations for herbs that may repel/deter ants. I'm growing the usual veggies for this time of the year and I live on Eyre Penisular in S.A.....so very hot and very dry summer altho I,m using heavy straw mulch. Thanks in advance.
