How do you preserve hornets nest?

To preserve a hornet's nest, first ensure it is no longer inhabited, ideally in late fall or early winter when hornets are dormant. Carefully remove the nest using gloves and protective gear, placing it in a sealed container to prevent damage. You can then use a mixture of water and a few drops of dish soap to gently clean the exterior, and finally, spray it with a clear acrylic sealant to protect it from deterioration. Display the nest in a dry, cool location away from direct sunlight to maintain its condition.
