IMO, the traps the USDA uses to detect AGH aren't real effective. Even in local areas where a nest was known to be active, their traps caught none or only a few. AFAIK, all the nests that have been discovered and eradicated were located by other means. Yet WSDA interprets "no trap hits in 2022" as some sort of proof that AGH aren't in the area. Call me very skeptical.
