Moved into a new home and there were carpenter ants mostly at the front of the home. I think it was moisture as the hose reel had most likely been dripping. Put the granules out along the front and front porch and inside on the window sills. The gel went in mostly the same places except on the inside I put it everywhere that was safe(we have a dog). Seemed to help but didn't really solve the problem. Plus its really hard to watch the ants eat and not swat them.
