It seems these pests have been making a comeback, and travelers everywhere are pulling down the covers of their hotel beds before jumping in, looking for the tell-tale little brown insects. Why the sudden resurgence, like a bad Broadway musical? "One reason is that the chemicals we use in pest control are safer today," says Heydon. "They break down more quickly. But that also gives the pests more time to get away and thrive. So to be effective, you need to increase the number of treatments."
Heydon is all for alternative, "organic" pest controls, within reason. "Remember some things that are labeled natural are just as harmful to humans as a chemical pesticide. You've got to follow the directions carefully."
