Seoul Metropolitan Area Deploys Water Trucks to Combat Lovebug Surge

Local authorities across the Seoul metropolitan area are deploying water spray trucks and collection devices to manage a mass emergence of lovebugs.

The seasonal surge has caused significant disruption for residents in cities such as Gwangmyeong and Incheon. Because the insects tend to swarm humans, the increasing population has led to a spike in public complaints and general discomfort.

Rising temperatures have accelerated the appearance of the adult insects, leading to higher populations this season [1, 2]. To mitigate the nuisance, municipalities are using water trucks to wash away adult insects from public spaces and deploying collection devices to trap them [1, 2].

The scale of the problem is evident in Gwangmyeong. Official records show that complaints regarding the insects rose from approximately 40 cases in 2023 to about 820 cases last year ^[1].

Residents have expressed frustration with the insects' behavior. "In our apartment complex, the number of individuals is very high, and because they have a habit of trying to stick to people, it is very uncomfortable," Baek Jung-hoon said ^[1].

While the insects are not known to be harmful to humans, their sheer volume creates a sense of unease. "It feels like they might be aggressive, and although they do not attack people, it is unpleasant because there are so many of them," Lee Do-yul said ^[1].

Local governments continue to monitor the situation as the summer heat persists, focusing on non-toxic methods like water spraying to reduce the population without causing further environmental harm [1, 2].
