A serial crook wanted for a spree of knifepoint robberies was busted when a homeowner found the guy sleeping on his couch in Queens, police said.

Khalif House, 24, who has allegedly hit 25 dollar stores and fast-food places since February, was arrested Wednesday.

The break came when Floral Park homeowner Bill O’Keefe found House sleeping on his couch.

“I said, ‘What the hell are you doing here?’ and he took off,” O’Keefe said.

Cops soon had him in handcuffs.
