I just had a customer e-mail and inform me that his yard has been ruined by grubs and he thinks that it is my fault! I have over 100 accounts and I have not seen any evidence of grubs in any of them. Is it possible to transfer grubs or anything else from yard to yard. He said he has to resod and then he will consider letting me continue, but only if I use his mower. I plan on thanking him for his business and moving on-- I would like to let him know it's not possible to transfer grubs- is it????
