The 32-year-old stand-up told The Guardian that the digital channel's output is monotonous.
When asked what he thought the greatest threat to comedy is, Howard replied: "The TV channel Dave.
"Everything is repeated there; they just play the same shows over and over."
Dave regularly repeats his popular BBC Three show Good News and BBC Two's Mock the Week, on which he has appeared as a panellist since 2006.
However, a spokesperson for UKTV has told Digital Spy that the comedian's comments were made in jest.
Howard is quoted as saying: "That'll teach me for giving a joke answer to a serious question from a broadsheet newspaper! Sorry Dave, you know I love you."
Elsewhere in the Guardian interview, Howard also said that his one TV regret is presenting backstage at the Brit Awards for ITV2 in 2007, confessing that he did not enjoy interviewing popstar Lily Allen.
"I didn't really want to be there," he admitted. "I just don't care what people like Lily Allen think about stuff. But I know that some people do care, so I couldn't just slouch through it."
Russell Howard's Good News, now in its sixth series, returns for an extended 12-episode run this Thursday at 9pm on BBC Three.
