It has been almost 3 years that we have been using Burr Chemical's services. We have needed those services for bed bug infestations in three different apartments. The most recent treatment was for general insect concerns that only the tenant could identify. Mike was here before I expected him (a pleasant surprise), did a thorough job quickly and neatly. He was very respectful of both the tenant and the property. I am very pleased and will recommend Burr Chemical to others as I can.
