Termidor SC bonds to the soil and does not move once it is applied. Therefore, it can be applied where a well or garden is present as long as it is more than 10 feet away from the well or garden or tree. We would suggest not applying Termidor SC along the side of the house that is within 10 feet of the trees. You should keep a close eye on this area of the house for termites, or you can of course always install some Termite Bait Stations in that area for monitoring activity.
