Keep away from them. I used them for a pest control for a while waiting to see that at some point it is going to work. I figured it out that I just need to cut my cost and run. Whatever they are using is not working. They would say that they would come back for free if it doesn't work and we still have problems. I week later after the application (very messy one) it wasn't working. I called and called and called. They refused to come unless I pay again. Tried to talk to their customer service representative. Good luck I don't really remember anybody been so rude to me . And I am not a whiny person and usually don't have time for reviews but I think somebody has to warn people from doing the same mistake and using them. Keep in mind they have several companies in Charlotte under the same name I had a misfortune to use two of them not knowing that they are the same. But the products they use exactly the same terrible and not working. Stay away and go with somebody else.
