No, don't keep them in the house. They are hardy plants and would not cope with the heat, dryness and low light of the house. You could plant them, heel them in temporarily or pot them up but they need to be kept cool and moist whatever you decide. You won't need to keep them 'several months' even if you decide not to plant straight away. You should aim to plant them before they leaf out ie when still dormant. And Raspberries leaf out quite early.

floral. Thanks.

If your ground is not frozen, I'd take it a step further and say go ahead and plant them now. Bare root plants can deteriorate rather quickly if the roots are not protected and the plants stay too warm and in the ground is the best place to avoid both of those issues. The plants can certainly tolerate the cold.

If the soil is not too wet to work; and raspberries prefer well-draining, non-soggy soil.
