Overview

• Swarming moths have hit Murcia, Valencia, Barcelona and the Community of Madrid as provinces report unusually high household infestations.
• Entomologists attribute the surge to an exceptionally humid spring followed by warm air masses from North Africa boosting adult moth emergence.
• These nocturnal Noctuidae live two to three weeks and are drawn to volatile compounds from fabrics, food and cleaning products rather than light.
• Homeowners describe being unable to hang laundry outdoors and suffering sleep disruptions as large swarms invade living spaces at night.
• Experts stress the moths carry no health threat and note that the cyclical outbreak typically subsides within days as adults complete their lifecycle.
