Does anyone know of an effective treatment to protect against getting termites in mulch beds. I have a customer we installed new mulch beds for this summer and they are worried about termites. They have had termite problems in the past, and Terminx told them that termites in mulch beds are very common. I am a certified lawn and turf applicator. I dont no if my catagory 7 would cover me on this or not. I know that Dursban is supposedly a good treatment, but you cant get it in PA. Is there any other chemicals I can use to effectively treat these beds?
