Do I need to drill a hole in each hollow section of the block and treat with Termidor?? I've treated inside and out of this block already with Termidor. But I think the termites came up through the block!!
You do not have to treat all of the hollow block walls, only the bottom 2 where the termites could come through the soil with Termidor SC.
