The poor cockroach still gets a bad rap while the fly gets a pass, according to a survey of 300 people by pest-control company Orkin.
When asked, "Which of the following would make you stop chowing down if you spied them while you were in a restaurant?" 61 percent said a cockroach.
Meanwhile, only three percent said they'd stop eating if a fly was buzzing around the dinner table.
However, Orkin entomologist and Technical Services Director Ron Harrison remarked, "Many restaurant patrons may not be aware that houseflies are twice as filthy as cockroaches."
Without getting too graphic, flies carry all sorts of pathogens on their legs and body's small hairs that are easily transferred to food or touched surfaces, according to Harrison.
Incidentally, other choices in the Orkin survey of critters you might (or might not) spot in a restaurant included rodents, ants, snakes and geckos.
