What's the best way to fill these holes in my laundry room?

My goal is to keep hot/cool air from seeping between floors. Is canned spray foam the way to go? Any recommendations? Pest resistance is a bonus.
Looks like refrigerant lines to an A/C system to me. Cold line is covered in insulation and hot line is bare. White cable could be power to the unit.
