Bedbugs have transferred to a new subway line in New York City.

A transit union official tells the Daily News that a No. 5 train was taken out of service Friday after a rider saw a bedbug fall off a homeless man.

The News says another bedbug was apparently spotted elsewhere on the Lexington Avenue line.

Restaurant manager Hector Barrios tells the newspaper he spotted one of the bugs on the floor of a No. 4 train Friday. Barrios says he killed it with a MetroCard receipt.

Three N trains were gassed earlier this week after bedbugs were sighted.

The Daily News says transit officials also fumigated two crew locker rooms.

Spokesman Adam Lisberg says the MTA can’t check riders for bedbugs before letting them on trains.
