polystrene beads for mosquitoe control
Floating layers of polystyrene beads suffocate mosquito larvae and pupae and inhibit egg laying.

The layers are very durable in breeding sites with water contained within walls, as in wet pit latrines and soakage pits. In some areas such pits constitute an important breeding site for Culex quinquefasciatus. Irantha samarasinghe (talk) 06:11, 27 November 2020 (UTC)
