Try shooting the ants with the laser.
I can turn that into a 500 mW laser if you want. :3
Or is it "enunciating"?
Perhaps teach the ants to play TPT.
Show a replica of an ant being killed by a laser. Then they all come, take arms up against you, employ the fire-ants, and "squish". hahaha.

Oh my goodness! Ants take over my bathroom too! A couple of years ago of course.
If you don't want to burn your house down. Try putting loads of sugar/honey in your next door neighbors living room. Then burn their house down.
