How bad can bedbugs be?
Summary
Dr. Michelle Dugan, a zoologist at the University of Galway, joins Moncrieff to discuss bedbugs after a Rome-to-Australia flight was cancelled due to an infestation. The expert explains that these resilient parasites hitchhike in luggage, feed on warm-blooded animals, and are notoriously difficult to eliminate due to insecticide resistance. Dugan details their biology, noting they survive for months without food and require extreme heat to kill. The segment concludes with a listener’s harrowing account of a severe bedbug infestation in a New Orleans hostel.
