Do I need to use stronger pest control?
Apologies for the not so good photo. I wish I had taken pictures prior to cleaning.
Every morning there is always a new batch of dirt/debris on the side of the garage door and lots of (what I believe to be) ants crawling around. I use Ortho Home Defense spray that I picked up from Home Depot but they always come back. There is a slight gap in that area, so the ants could be crawling in and out of that area.
Could the ants possibly be building a nest inside the gap and should I be using a strong pest control solution? I do not believe they are termites in this case, but am ready to get a termite inspection, if needed.
