It depends on why they absconded. You need to do a bit of an autopsy…
If there’s no sign of transmissible disease and the frames and comb are in good shape and not slimed out or something then you should be good to go with the old frames.
You might consider a nuc or a split from another hive, if that’s available. You could get a mated queen to go with you split to further accelerate the process. Those will give you a stronger start than a package.
Make sure you have a good varroa plan in place if you didn’t already. Unless you specifically can prove otherwise, mites are a good guess for why they absconded/died.
Hi Fred, after you check through the box as @chau06 said you should store the frames so they can’t be damaged by rodents or other insects before you get your new bees. Assuming it’s cold and dry where you are until then, you can leave the box with frames in it where it is - but block off any entrances including bottom screen if you used one. Eggs potentially left by pests should be killed off in your Colorado temps
