Danny Camacho's forearms are covered with red welts, in the clustered pattern distinctive to the bite of the Cimex lectularius. Camacho lets bed bugs feast on his blood bimonthly. The 55-year-old has to keep the insects well-fed so that when he scatters them around his home in New York's borough of Queens, they'll exude that fresh bed-bug scent.
These are the practices that help keep Camacho's work partner, Champ, at his peak. And how else would you train a bed-bug hunting Beagle?
