How do I find out where ants are coming from?

Answer by  ts9818a (139)

Set out some crumbs and wait for the ants to come and get it. Watch where they return to as that will be the location of their nest.

Ants leave a trail to follow from the nest to the food source, instead of killing them, watch them and see where they go or sprinkle corn meal outside in the grass around the house, they love, they eat it, they take it home to the queen and cannot digest it and die.
