We have ant crawling all over the outside wall near the entrance and have contacted Pest Control which cost us a fortune but they have come back we have now resorted to buying spray ant traps and powders we think that the nest could be inside the wall cavity any idea
Good remedy to get rid of ants is very simple and non-toxic to pets and all. Sprinkle some cornmeal wherever you see them (baseboards especially) and they will take the meal back to their colony and die. This takes about 1-2 weeks before you will notice a difference, but it's well worth the wait. When I was doing this, ants that I saw I scooped up and put them in the pile.
