Senators can also be impeached, then tried, possibly removed from office .... and also ... prevented from ever holding another federal office.
Article II of the United States Constitution (Section 4) states that “The President, Vice President, and all civil Officers (Senators) of the United States shall be removed from Office on Impeachment for, and Conviction of, Treason, Bribery, or other High Crimes and Misdemeanors.
William Blout (Senator from Tenn and signer of the Constitution) was impeached but the charges dismissed after being expelled from the Senate in 1797.
The President, Vice President and all civil Officers of the United States, shall be removed from Office on Impeachment for, and Conviction of, Treason, Bribery, or other high Crimes and Misdemeanors.

While theoretically possible for the House to 'impeach' a Senator, the Senate would conduct any trial. In reality both houses are the sole judges of who may be a member of their respective house. If it didn't occur already to the Senate to remove a Senator for cause, it's unlike the Senate will ever pay much attention to a House attempt to remove one of them.
I seriously doubt Harry Reid would even bother having the clerks file such a bill coming over from the House.
As Ben Franklin said, assassination was the traditional way to remove the head of state but he preferred impeachment. At the same time neither Franklin nor any other of the Founders writing the core of the Constitution thought we would ever have anyone in office other than someone chosen by the best people, of wealth and power, and property.
By 1800, 10 years after its adoption, Thomas Jefferson fooled them all!
Waste of time to impeach Levin. He’s retiring and has plenty of friends to help him drag it out till he’s out of office.
