Overview

• A clean mist of water from a standard spray bottle mimics rain and sends single wasps back to their nest within seconds.
• The Landesbund für Vogel- und Naturschutz Bayerns warns that spray bottles must be rinsed thoroughly to remove chemical residues that could harm insects.
• Experts caution against blowing on wasps because exhaled carbon dioxide triggers an alarm response that can provoke stings.
• When wasps land on food, residents should calmly shoo them away with a piece of paper or use water mist instead of panicking or resorting to chemical repellents.
• Under Germany’s Bundesnaturschutzgesetz, wasp nests may only be removed by certified professionals, so households are urged to focus on simple, nonlethal deterrents.
