Residents in a central Manila neighborhood lined up Wednesday, as dengue cases spike nationwide, to collect a bounty—one peso for every five mosquitoes, dead or alive.

To combat a dengue outbreak, a Philippine village is offering a bounty of one Philippines peso for every five mosquitoes residents turn in.

A village in the densely populated Philippine capital region launched a battle against dengue on Wednesday by offering a token bounty to residents for captured mosquitoes, dead or alive. The unusual strategy adopted by the Addition Hills village in Mandaluyong City reflects growing concern after the nearby city of Quezon declared an outbreak of the mosquito-borne illness over the weekend.
