If you want to go organic, there are several options: You can plant Mint or Tansy around the perimeter of your home. Both of these plants keep ants away, however with the heat of Summer upon us planting anything is probably NOT an option. Another thing..Tansy and Mint are both very evasive. So they will multiply and take over. Two treatment options are 1) Orange Oil. Mix up a water and Orange Oil solution in a spray bottle or Pump Sprayer and spray all around the perimeter of your home and anywhere you see ants coming inside your home (weep holes, cracks, windows). 2) If you do not want to mix your own, there is a great product on the market called EcoSmart. It is a completely organic non-selective pesticide made of Clove Oil, Spearmint Oil, and some other herbal oils. It comes in both Aerosol and Pump Sprayer(for bigger jobs). If you use any of the "spray" options, You will have to re-apply after rain or sprinklers. Otherwise just every few weeks or so. Oh, one more thing... both of the pesticide options are safe for kids and pets!
