insulation question

Not sure where else to post this.

I have these bays between the joists in my laundry room. See picture below.

IYou can actually see the exterior brick if you get up there and look down.

Do these bays need to be insulated? Would rigid foam on the bottom and exterior portion caulked into place do the job or just shove some fiberglass batts up there?
