Why isn't Optigard Flex labeled for pharoah or carpenter ants?
If it works well for other ants why not them?
Some ants act differently than other ant species which could limit the way the product would spread through the colony. Manufacturers will only include an insect on their product label if it meets certain criteria and for some reason they felt the product was not effective enough on Pharoah and carpenter ants. If you need more specific information as to why they were not included you can contact Syngenta, the manufacturer, directly by calling 866-796-4368.
