Many parks, recreational areas, and outdoor venues in California are home to yellowjacket wasps (Vespula spp.). Yellowjackets are commonly attracted to human food items, creating a serious nuisance and a potential stinging threat.

Outdoors, they disrupt biological control by tending honeydew-producing pests and protecting them from natural enemies. Argentine ants are also common invaders of urban residential settings, making them the nuisance ant species most often treated by pest management professionals (PMPs).
Contact insecticide sprays are frequently used control options for Argentine ants due to practical advantages, such as easy application and.../span>
