Terro Ant Traps. They work good.

 Been having an ant problem at the house.  Hordes of them scuttling every where.  Upon prodding from Youngest Son, I bought a pack (four) of Terro Ant Traps and put them out.  They are working. I have hardly seen a single ant where I used to have hordes of them.  Dunno just how they work.  I don't see any dead ants in the traps, which are clear plastic with a clear liquid inside them.  Maybe they poison the ants so they scurry home and die in their nest?  Maybe they emit an smell that drives the ants away?  Beats me.  I am happy just to not see hordes of ants cruising my kitchen.
