I guess it depends on what kind of ants, but Amdro really works well on fire ants.
I still have scars from fire ant stings decades old.
They are EXTREMELY nasty.
Carpenter ants eat your house. Fire ants eat YOU!
The Amdro product I used (and found worthless) was the Amdro Ant Block, so I have no experience with their fire ant product (thankfully we don’t have fire ants around here). That stuff may work very well.
