How do I treat around Concrete Stairs for termites?
Pretty sure most of these concrete stairs are soil/gravel filled (not solid.) Do I treat the soil around the perimeter of the stairs or drill directly into the stairs at the top near the exterior wall of the house? (some are 3-4' high) Also, we have a crawl space so I will be doing the foundation perimeter there, will doing this cover that area enough so I can skip the stairs?
When you are treating around dirt filled concrete stairs or porches, you should trench around the base and perimeter of the stairs or porch first. Then, you are supposed to drill through the top of the stairs against the foundation or exterior wall of the house as you indicated. This is to get the product into the dirt that is filled in the concrete stairs or porch. You should absolutely treat the entire inside of the crawl space as well, but this will not take place of drilling the outside stairs. You should do both. This is because you never know where termites are going to try to get into your home and it is always recommended to cover all your bases and do the most complete treatment as possible.
