Yes. As long as you know where they are located, you can dig them up and either store them over winter or divide and replant elsewhere, depending on your location.
We moved to a new house, and spider lilies popped up in our front yard. I am currently digging them all up and I think I'm going to have over 100! Any advice on how and when to plant these? Also, a few bulbs where damaged in the process of digging them up. Can I still plant these? Is it unusual to have this many in one spot?

I have quite a few red spider lilies by the front door. I've noticed a number of bulbs showing above the surface of the ground this fall. I live in North Texas and it will soon be time for them to start their bloom cycle. What should I do with these bulbs that are showing?
Here's an article with some tips:

We have what I think is a giant spider lily. The leaves and flowers started to grow rotting.
It may have been overwatered. It also could be that an animal bit off the top as it started to grow.
