I have used A1 Exterminators for years now and have alway found them to be one of the best companies in Boston. They are thorough, professional and take care of all of my pest problems. I am especially grateful to Sam who have served my house of the past 2-3 years. He is an excellent employee of A1 and really knows how to take care of any issues that I have. The company is fortunate to have him on their crew.
