Have been using EcoGen since I built the new house in 2015..Never have I had a bug issue. My tech, Mark, is amazing! He is extremely knowledgeable and thorough, and side note is a nice person which is hard to find in the service industry. He can easily answer any question I have about the service and back it up with info that I should know but since it's not common knowledge it is cool to be given the heads up about. Highly recommend this company!
