    "concept_summary": "Essential oil extracted from Nepeta cataria (catnip) is infused into sand to create a chemical barrier that deters termite tunneling and, at higher concentrations, kills termites. Laboratory tests showed reduced or eliminated tunneling compared with untreated sand.",

Direct exposure tests demonstrated termite mortality at higher oil concentrations, though less effective than commercial termiticides.",
