Will Altriset work on leafcutter ants? What is the best product for these types of ants? Would Termidor work?
Altriset is not labeled for use on ants. Termidor SC will work for most species of ants but it is not specifically labeled for leaf cutter ants. We believe the reason leaf cutter ants were not included on the label is because most people do not have leaf cutter ants on their homes or trying to gain access to their homes and Termidor is only allowed to be used on or immediately around a structure. Leaf cutter ants can be a difficult pest to get rid of. The colonies are large and the 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. We have had several positive results from customers that used Termidor around the outside of their home for leaf cutter ants
