Pests like cockroaches are a huge detriment to a Swiftlet House. Cockroaches are destructive insects which will gnaw at the nests of the swiftlets, leading to holes in the nests. This damages the nests and cause economic losses.
As a side note, the presence of cockroaches in the Swiftlet House will also cause a disturbance to the closely monitored atmosphere, smell and environment in the house. This may affect the attractiveness of the House and swiftlets may not return to the House.
