¿Colgar una bolsa de papel marrón ahuyenta a las avispas?

Natural analysis: There are indeed certain rules for the lack of harmony between humans and nature. There is a certain reason why some people say it is useful. Firstly, the color of kraft paper or kraft paper bags has a certain degree of similarity to that of honeycomb.

This method is based on the territorial awareness of wasps, especially hornets and wasps. When they see objects similar in shape and color to beehives (brown, pleated kraft paper bags), they might mistake them for large beehives that have already been established by other bee colonies.

To avoid conflicts, they sometimes choose to stay away from this area. Some people put kraft paper to inform the queen bee that there is a landlord here and ask her to go elsewhere. Some people put kraft paper bags to prevent the spread of wasps. They actively inoculate the scattered wasps on the paper bags to form beehives and then gather them all at once to catch them.

Why is it said that the effect is limited and unreliable

Not effective for all wasps: This method mainly targets social wasps with a strong sense of territory (such as wasps). For solitary wasps or bee colonies that have already built nests near your home, the effect is negligible.

It may be “seen through” : wasps are intelligent insects. If the paper bags have no texture or smell of nests and no wasps moving in or out, they will soon realize that it is fake and thus no longer be afraid. You can also kill a wasp and put it in a kraft paper bag to give off a smell, making the wasp believe it to be true.

It only has a “deterrent” effect and does not solve the fundamental problem: at most, it can only prevent new wasps from exploring, but it is completely ineffective against bee colonies that have already built nests in your house structure (eaves, wall holes, ventilation openings). They have made their home and won’t be scared away by a paper bag.

Hanging kraft paper bags is more like a “psychological comfort” or a way to take a chance, and should not be the main and reliable means to repel wasps.

You can try this: If there are only a few wasps flying around in the yard occasionally and they don’t have a fixed nest, you can try hanging one. It’s low-cost and harmless, but don’t hold it too high.
