Yes, but you can just buy a papery fake wasp nest at the dollar store for cheap. I got one of those and no wasps since. You don't need to learn to crochet, but you can if you want I guess.
Maybe it's different for hornets, but I've seen paper wasps build their nest right below and completely attached to an older nest.
We have a fake hive like this in our garden. Used to get wasps every year but haven't seen a single one since.Anecdotal but I believe it works.
