A fly-killing device is used for pest control. A fly-killing device typically attracts flying insects, for example houseflies, wasps, moths and mosquitoes. The insects are killed or released.
Famous quotes containing the word device:
“UG [universal grammar] may be regarded as a characterization of the genetically determined language faculty. One may think of this faculty as a language acquisition device, an innate component of the human mind that yields a particular language through interaction with present experience, a device that converts experience into a system of knowledge attained: knowledge of one or another language.”
—Noam Chomsky (b. 1928)
