The Home Depot ones are usually made to be left outside, at least for a month. You just need to make sure it doesn’t say outside in a covered area (like an outdoor patio) on the box. Almost all of Spirit Halloweens stuff is not meant to go outside, which I’ve always thought is kind of silly. What I usually do is cover the electronics with a garbage bag underneath the clothing and tape stuff up. The biggest thing you have to worry about with the giant HD animatronics (or from anywhere else) is making sure they don’t fall over. I use trampoline stakes bought off of Amazon, but I see HD sells them now with the Halloween stuff. Besides keeping everything in place during a wind storm, they also double as theft deterrents. I usually use 8 on the big stuff and 4 on the small stuff. You could probably get away with using less though. More on reddit.com

Haunted Hill props are pretty bad quality to begin with, I cannot imagine those rated for indoor usage surviving outdoors. More on reddit.com

Just be aware you're limiting the life of them by a few years. I use large contractor bags over mine including some fairly large pain in the ass ones. I've had a few the past few years, but mine are 100% outside from mid September to the week after Halloween. I love them but I really hate that they're not even remotely waterproof. Hundreds of dollars and in reality they're really just Chinese junk. Some will put bags over the motor/sensor boxes. More on reddit.com

Most of the static props do ok (I have the HD skeletons, pumpkin stacks, inferno and such uncovered). I have put distortions uncovered out (but only the static/ minimal movement). Pumpkin stalker, jack attack and jack widow have made it just fine thru some rain storms. But I do not risk some of the others. Most of the full range animatronics (larger movement) are covered. The biggest problem I have had is wind. Those large guys need to be nailed down. We have cords, spikes, weights, and ties to trees on most. We did bust one prop (weld) due to wind. But overall, they really are nailed down. (Also deters anyone walking off with them). Its a real pain but we do “temporary buildings” that are like small sheds for some of them. (Made to mimic a mausoleum). It just means a bigger put up and take down but keeps the animatronics dry.
