Wasps are the ultimate party crashers. These uninvited pests can easily make your guests run out the door screaming in no time. Luckily, there’s a way to stop wasps from ruining a perfect outdoor dinner party. As it turns out, when wasps see another nest, they won’t even come near that area in order to avoid confrontation.

Here’s what you need to do so you can enjoy your BBQ without having to worry about uninvited guests.
