Hi Caddymom, Welcome from me too!
I agree, you plant is a variety of Dwarf Umbrella Tree (Heptapleurum arboricola)
It's spindly growth habit is likely due to lack of sufficient light. They are used as landscape plants here in Florida and are very popular as indoor houseplants too.
As gardenfish mentioned, whenever you move a plant outside, there's a chance that insects or other critters will take up residence. During hurricane season a couple of years ago, I moved a couple of small plants from the screen room into the house and a tiny tree frog hopped out of one of them which was no big deal, it was easy to catch and release ... but I'm leery about moving plants into the house if they've been outside for any length of time because many years ago, I brought in a large Weeping Fig tree from the patio, thinking it would look great in the corner of our bedroom and when I got up early the next morning, I stepped on a black snake!!
My husband was in the kitchen at the other end of the house and heard me screaming and thought I was having a nightmare. He managed to collect the snake and take it out to the wooded area behind the house and I had him move the tree back outside too! I did have trouble sleeping for a few nights afterwards, thinking that snake may have brought it's family along and they were hiding in a corner of the closet or under the bed!
