The service was monthly and sadly there are fleas now and then spider bites on me after Brezden came out on the 6th month! I called the sprayer and asked questions he told me he is using a "new" product it is orderless, I saw that it was also invisible compared to their initial sprays! "Ray" at Brezden talked over me, argued and told me all about how he "only" does a great jobs, I asked if he would fix this re spider bites, he says "no, he won't" and he would not listen, to the point I had to hang up letting him go on talking about himself. I called a different company to work with and I will be sure to let all my neighbors and friends know about "Ray" at Brezden Pest's customer service. BE advised also they want a contract so they can charge you a months service to quit them. Good Luck, customers. I will post an awesome review when I find the company that is awesome. It is not Brezden.
