BEDBUGS — AN ECO-PROBLEM? Reader Tom Brosz writes: “I’ll tell you where at least some of the bedbug problem comes from. Used to be years ago hotels washed their linen in steaming hot water, and everybody got fresh crisp sheets every day when they stayed there. Nowadays, it’s all ‘green,’ and cold water washing at hotels is the rule of the day, along with places that don’t change your sheets unless you ask. I hope to God they still change them between customers, but sometimes I wonder.” Those old laundry customs were designed to limit the spread of bedbugs (and other gross things) but people have gotten complacent, I guess. . . .
