Lasius interjectus, commonly known as the larger yellow ant or larger citronella ant, is a North American ant species distinguished by its yellowish coloration and distinctive lemon-citronella scent. Formerly classified in the genus Acanthomyops (now a subgenus of Lasius), this species nests in soil, often along building foundations, and is known for producing alate swarms that sometimes emerge indoors. The species poses no structural threat to buildings and is recognized by its chemical defense using citronellal and formic acid.
