fly-killing device

Flypaper is a fly-killing device.

A fly-killing device is used for pest control of flying insects, such as houseflies, wasps, moths and mosquitos.

Flypaper (also known as a fly ribbon) is a fly-killing device made of paper coated with a sweetly fragrant, but extremely sticky and sometimes poisonous substance that traps flies and other flying insects when they land upon it.
