I was totally against the fake tree, but one year we brought a real cut tree in our house and it had some bug eggs on it. Christmas eve we noticed lil black poppy seed looking things on the presents. Thought it was odd, but didn't investigate further. Shortly after Christmas, and I'm talking probably Dec 26th, wife packed up all the ornaments, then it was my turn to haul the tree out. I reached in and grabbed the trunk, it was all cold and slimy. I was like WTF, found the trunk covered in some bug larvae. Wife freaked out, do not pass go, do not collect $200, the tree is going outside via the window...RIGHT NOW.
That was kind of nasty, been fake tree ever since. I miss the smell and the joy (or hassle) of going out and picking just the right tree. Its real nice just setting the fake tree pre-strung with lights, plug it in and start decorating.
