I used a place called eco care pest solutions. Explained my tanks. He used a product with a pinpoint applicator inside and out, never a problem. I had moisture ants which are as damaging as termites. I was concerned about having to tent and he said they don't really need to do that anymore with the right product unless your house has been completely saturated with moisture down to the framing for a long time. I did need to remove the wall paneling in the basement to remove dead ants/nest and dry the framing. This was a 1920 house so no sealed concrete/French drains. For simple cockroaches any reputable company should handle it no problem with a monthly contract to spray. The key I learned with cockroaches after years living in various apartments. Clean up every source of food, behind fridge, stove, etc... Force those buggers to find a food source elsewhere and no chemicals are needed
