Instead of killing a wasp, confuse it.

If wasps are bothering you, use the plant sprayer instead of hitting or getting the spray can.

Wasps are vexing, yet they serve a purpose: they are nature's scavengers. As a result, the more wasps you have, the less mosquitoes and flies you will encounter. Wasps do, in fact, seek vengeance after death. The venom of a wasp releases a specific pheromone when it is killed. Other wasps will become more aggressive as a result, and you will be more likely to be stung. 

There's a lot easier way: just use water. The problem is that if you spray water on wasps, they will believe it is raining. Wasps have a strong aversion to rain and will promptly return to their nest if it rains. Due to its wet wings, the wasp will have difficulty flying and will consequently swiftly drip off. 

And if you're going to work on your garden or balcony right now, you can undoubtedly take wasps' preferences into consideration. Wasps are attracted to meat and sweets, but lemon, cloves, and geranium are repulsive to them. Wasp repellent scents have been studied, and they work effectively in a herb garden. You can keep wasps away from your patio or balcony with a herb garden or jars of fresh herbs. Wasps are kept out of your home with the use of screens and fly curtains.
