I had a roach infestation in my house. J&E was chosen by my rental agency. They came out on a Monday and laid granules around the exterior of the house and sprayed the inside as well. I was told that I should start seeing dead roaches within a couple days. Instead of seeing dead roaches I began to see more live ones. I called them back and the secretary then tells me, I won't start seeing a difference for about a week. They continued to multiply. Finally on day 5 after calling J&E again and asking what they used to which they would not give an answer, I called another company who came out same day and sprayed. I began seeing results within hours of him leaving. The next morning, I swept up a ton of dead roaches and saw less live ones walking around. If you have an option on the exterminator choice, STEER CLEAR of J&E Pest. You will end up paying another pest company to come behind them.
