A report released earlier this year morning names Baltimore as the city with the most bed bugs in the country.
The Maryland city moved up nine spots from its 2016 ranking.

The cities were ranked based on treatment data from the metro areas where Orkin performed the most bedbug treatments from December 1, 2015, to November 30, 2016.
‘We have more people affected by bed bugs in the United States now than ever before,’ Orkin entomologist and director of technical services Ron Harrison said. ‘They were virtually unheard of in the U.S. 10 years ago.’
Orkin calls bed bugs ‘hitchhikers’ that travel from place to place.
Orkin officials think bedbugs have become prevalent because they’ve built up a resistance to chemicals.
They also said you might not know you have bed bugs because many people don’t have a physical reaction to the insect’s bites.
