Thought I'd try placing paper bags throughout the Garden to try and keep wasps from building their nests in the cracks of our raised beds.
Since wasps are territorial, they think that other wasps have already built here and will find another place to make their homes.
We like pollinators in our Garden, but are also concerned about public safety. This is a chemical free way to try and deter the wasps. So far, it seems to be working.
