I recently (this spring) hired Okolona Pest Control (also known as OPC) to exterminate the ants in my house. I am pregnant, which I told the company when I set up the initial appointment, and they said that their product was odor free and would be safe to use around me. Apparently that message never got to the exterminator because he freaked out when he found out I was pg. Well, after several phone and service calls, the matter was resolved and the ants were finally gone. If this incident had not happened, I would have gladly given them a higher rating. Other than that, they do offer a good and efficient product.
