Thirsk and Malton MP Kevin Hollinrake said he would be "appalled" if his children left home and claimed housing benefit.
He suggested young people should stay living in their family home where they already have a bed rather than moving out and costing the taxpayer cash.
Mr Hollinrake made the comments as MPs debated Government plans to stop 18 to 21-year-olds from claiming housing benefit.
The MP for Thirsk and Malton said: "As a parent of two children between 18 and 21 I would be appalled if I felt they were going to leave home to live a life on housing benefits while they have still got a bed in my house.
"Will the minister agree, will the minister confirm, that there will be support made available for those who are vulnerable or have complex needs?"
Work and pensions minister Caroline Nokes replied: "Absolutely, yes.
"For those who cannot live with their parents, for those who are in receipt of the main disability benefits, they will be exempt from this policy."
