Thank you guys for the help. Like I said though, they are not having termites in the bark now, they had a problem previously. They just want to take a good prevenative step just in case. I told my customers I dont anticipate a problem, but if there is they need to take it up with Terminx. They must not be to worried because they said they plan to have me remulch in the Spring. My biggest concern is having them blame me if a problem does occur.
I do not do this for the love of the game. I do this for the money.
