I had ants this year too, for the first time. I’m not one for trying pest control stuff myself. I don’t trust the consumer grade products you get from Home Depot and such. So, I hired an exterminator. I went with Apex, but if I had to do it over, I’d have chosen TNT Exterminating. Regardless, I had one treatment done and the ants disappeared within 2 days and I haven’t seen them since.
