Mornin Mechanic,
We have used Terminix. A few years ago we had a very bad mealey moth (sp?) problem in our Ct home. It took them a few visits and my wife and I emptying the kitchen of any meal products to finally get rid of those pests. We couldnt have any breads, pasta, cereals etc stored in the house at all. We bought a cabinet for the garage to store all these items and so far, knock on wood, no mealey moths /forums/images/graemlins/grin.gif
To your original question, I would say they did their job although it took awhile ! Be glad to answer any other questions!
