We have been using O'Connor's for almost 3 years and they are as professional as they come. They always call a day or a few days prior to coming by as a reminder. We have seen little to no pests in our home and yard and they few times I have, I just call and they come right out and spray again. The customer service in the office is also great, when I call with a question or to change my payment method, they are always kind and helpful. Can't recommend enough.
