Wasps are unfriendly guests pretty much everywhere. Over at Household Hacker, they recommend using a brown grocery sack to trick wasps into staying away.
Some species of wasps tend to avoid a pre-existing wasp’s nest, so by crumpling up a brown paper sack to resemble a nest, they may be tricked into avoiding that location. This one tip is hard to test and there isn’t much scientific evidence behind it. Some companies sell commercial fake wasp nests on Amazon, and the ratings on these faux nests are pretty high. Besides, anything you can do to stack the deck in your favor against these nemeses can’t hurt.
