Bedbugs
Bedbugs won't kill you, but the trouble they cause may have you wishing they would. In 2010-11, as thousands of Americans woke up with itchy pink welts, they were reminded of the meaning behind the adage "Sleep tight; don't let the bedbugs bite." Infestations have been reported in all 50 states, and in the latter part of 2010, they were at nearly epidemic proportions in New York City and other metropolises. When the tiny bugs, which can produce 10,000 babies in three months, arrive, the cost to wipe out an infestation in a single-family home can run past $1,000. Perhaps the most evil thing about them is that, despite their small size, their anatomy is custom-built for bloodsucking. The apple seed–size insect can drink more than three times its body weight in blood in a single feeding.
