In the United States bug is not confined, as in England, to the domestic pest, but is applied to all insects of the Coleoptera order, which includes what in this country are generally called beetles. [Farmer & Henley, "Dictionary of Slang and Colloquial English," 1912 abridged edition]
"to scram, skedaddle," 1953, of uncertain origin, perhaps related to bug (v.2), and compare bug off. Bug out (n.) "precipitous retreat" (1951) is from the Korean War.
