I have been using Boo,s twice a year for over 5 years with no problem. They are very professional in everything they do. They always contact me in the spring and fall to schedule my treatments. The guys are always on time, and do a great job. One year in the spring they sprayed the exterior of my property and in a hour after they left it poured down rain, It was maybe a hour or so after the rain started they contacted me to schedule a time to come back and respray my property.
