I'm moving into an old house with large black ants currently crawling over my front porch. I'm going to be doing some work under the house like fixing leaks, putting wood panels behind lattice work so critters can't get in, and putting plastic on top of the exposed dirt of the crawl space. Do I need to find out where the ants are coming from and spray first, or is that spray going to be toxic to whoever's working under the house? I've seen a couple little ant hills in the back yard, but I'm really hoping the house isn't sitting on one huge one! Kirsten
