Although Navigator SC can be used only around the outside perimeter of the home and can help with some ants, it is not labeled to help with leaf cutter ants. Leaf cutter ants can be a difficult pest to get rid of. The colonies are large and these ants make their own food so poison baits only have limited effects on this species of ants. According to several university websites, Maxforce Complete Granules containing hydramethlynon are some what effective, though they will usually eliminate only about 30% of a large colony in one treatment and will need to be reapplied several times. DeltaGard Granules is one of the only products actually labeled for leaf cutter ants. The product label recommends treating the mound directly and lightly watering the granules in. Again, it may take several treatments to get the desired results. We also recommend contacting your local cooperative extension office to see if they have any recommendations for products that have worked for other people in your region.
