German and Indonesian experts evaluate wasp‑deterrent tricks for gardens

In Germany, experts dismiss the popular paper‑bag method for keeping wasps away, explaining that the crumpled bag does not mimic a rival nest and therefore fails to deter the insects. They advise instead using a spray bottle of water, setting up a fan, or gently shaking wasps away, warning against blowing or striking them, which can provoke aggression.

In Indonesia, gardeners are encouraged to plant species that naturally repel wasps. Lavender, geranium leaves, mint, and lemon balm are highlighted for their scents that deter the insects, while also providing attractive décor for patios and tables. These botanical options offer a chemical‑free way to reduce wasp activity around outdoor meals.
