There’s no easy way to calm down swarming wasps, especially if they are already agitated. Stay far away and wait for them to settle down to avoid injury. If you’re attempting to DIY kill a very small wasp nest, wait until night to apply wasp spray, as they are calmest and most docile when it’s dark.
