A man who tried to rid his Woodbury, NJ, house of bedbugs ended up burning down the place.

The man used a space heater, hair dryer and a heat gun Tuesday to wipe out the pests in a second-floor bedroom, authorities said. But he sparked a fire that led to his being hospitalized with unspecified injuries.

Internet remedies for killing bedbugs are a “catastrophe in the making,” said Woodbury Fire Marshal Joseph Buono.
