Fire Ant Control: Why Sugar Baits Don't Work and What Does

Wondering why fire ant baits use protein-based oils instead of sweet syrups? Entomologist Wayne Gardner explains: fire ants consume proteins, fats, and sugars, but they're far less attracted to sweets than Argentine ants.

Effective Bait Strategy

Baits outperform contact insecticides because a single area can harbor numerous colonies—contact poisons never reach them all. Successful baits rely on delayed toxicity: foragers carry the active ingredient back to the colony before it takes effect. The winning formula? Protein-rich oils (like soybean oil) absorbed onto an inert carrier (such as ground corn cobs).

This combination exploits fire ant foraging behavior for colony-wide control.
