bedbug (n.)youdaoicibaDictYouDict[bedbug 词源字典]
also bed-bug, 1772, from bed (n.) + bug (n.).
[The bed bug] is supposed to have been first introduced to this country in the fir timber that was brought over to rebuild London after it had suffered by the great fire; for it is generally said that Bugs were not known in England before that time, and many of them were found almost immediately afterwards in the new-built houses. [the Rev. W. Bingley, "Animal Biography; or Anecdotes of the Lives, Manners, and Economy of the Animal Creation," London, 1803]
