I refer to this post I’d written not too long ago, on using a newly-bought liquid ant killer.

Over the past week of daily   application along my house all the way to the other end of my neighbor’s house, I have seen a gradual decline of ants along their usual trail.

The day after I’d applied the ant poison outside one of my neighbor’s house, my neighbor approached my dad to tell him what I did (I asked for his permission first), said that the ants IN his house had vanished, and asked if I could buy a set for him.

I suppose this 1-step ant killer does work.

Their ant poison can be found here.
