Another Goof

Ants don't eat sugar!
You put sugar down in front of ants, they walk right by it and over it.
Ants want greese and fat, maybe even meat scraps from other bugs.
possibly plant material for moisture.
But not sugar.

From an entomological perspective, there's really no such thing as sugar ants. People use the term sugar ants to describe any number of ants that happen to like sweets. Depending on where you leave, your sugar ants may actually be Argentine ants, odorous house ants, pavement ants, or some other kind of ants.
