We recommend the usage of ant baits indoors, especially in cold weather whereby ants won"t travel exterior as often. A gelatin bait choose Optigard Ant Bait gelatin is an extremely effective.

Unless you usage a non-repellent spray such together Taurus SC or FUSE , baiting is the wanted treatment over typical residual spraying of repellent insecticides. Baiting is the many reliable method to remove the whole colony. When picking Ant baits, the is best to pick from both the sugar-based baits and also protein/grease-based baits. If using a spray, choose a non-repellent type unless you space treating the nest itself.

Why Ant Bait?

The use of residual sprays or dusts tension Ant colonies, resulting in them to separation into sub-colonies and also scatter. This scattering, also called budding, multiplies the variety of Ant colonies, and also thereby multiplies your Ant problem.

When girlfriend bait, use a slow-acting bait. Quick-kill insecticides and also baits will only kill the foraging Ants, not allowing those worker Ants to take the bait back home to feeding the queen, swarm workers, and brood.

If the Ant bait that you are at this time using is not effective (if the Ants space not visiting the bait) girlfriend will need to change the baits. Slow-acting baits administer a variety of the foods items the Ants find in nature. Instances are: various other insects (proteins/grease-based baits), nectar, aphid honeydew, and plant commodities (sugar and carbohydrates discovered in sweet-based baits).

Choosing a bait needs an understanding of the nutritional needs of the colony. Come be sure that you have all the baiting needs met, you might want come be prepared with a sugar/carbohydrate-based bait, a grease/fat-based bait, and a protein-based bait.
