Whenever you are performing any kind of service against your house one thing to be mindful of is the drip line. The drip line is the area directly under where the roof overhangs the house. Sometimes you can even see a worn out eroded area where the water rolls off the roof and hits the ground. In this case we are performing a termite treatment and need to make sure they are far enough away to not get a constant drip of water on them. Otherwise water would eventually wash away all of the product and prevent the treatment from being effective. The same thing could be said about your landscape plants as well. Having them under the drip line could cause erosion and wash away your beds. Hope this helps!
