Maximize Ant Control with Baiting

An often-overlooked component in effective ant management is exterior baiting with gel or liquid baits. Granular baits, which consist of a carrier (often corn grit) and an attractive food source like soybean oil, are what many PMPs think of when they think about exterior baiting. This can be a highly effective approach especially for fat- or protein-loving ants such as fire ants. However, when dealing with sugar-loving ants like Argentine ants, odorous house ants, ghost ants and others, both the size of the granule and the attractivity of the food can reduce uptake. For these sugar-loving species, gel and liquid ant baits are often the best way to move more active ingredient into the colony or colonies.

Traditionally, gel and liquid ant baits are applied on the interior where ants are found, but with large tramp ant populations this may not eliminate the problem. Ants forage indoors for food and water, and if they can get that food outside, they will quickly consume that resource. Tramp ants are successful for numerous reasons: They can overwhelm native ants due to high numbers, they are aggressive to non-nestmates and different species, they often have multiple queens and nesting sites, and critically, they quickly and effectively outcompete other ants for resources.

In small-scale field trials we find that carbohydrate resources like sugar water and honey are exploited very quickly, often within a few hours of placement within a foraging area. This why baiting outdoors with gels and liquids can be so effective; you do not need a gel or liquid bait to last for weeks or even days outdoors. Ants will exploit these resources in a very short amount of time and quickly divert these resources to other individuals within the colony, including the larval and reproductive castes.

Exterior baiting is even more effective when it is combined with a non-repellent labeled for use away from the structure. By applying non-repellent residuals to foraging trails and then baiting over or around the treated area, you create an ideal attract-and-kill scenario whereby you incentivize ants to cross the material with the bait.
