How to get rid of a paper wasp nest?

Paper wasps usually build their nests under eaves and ledges of a house. Though paper wasps are not so much aggressive like hornets or yellowjackets, their nests should be removed carefully as they will attack you if they themselves or their nests are threatened and their stings are painful and may cause serious anaphylactic reaction.

To destroy a paper wasp nest, you should first buy a wasp and hornet spray sold at most grocery and hardware stores.  Before starting the fight you should first cover every inch of yourselves with clothes. Make sure all the wasps of the colony are inside the nest. Be prepared for any unexpected attack from the opponents. When you are fully ready, just spray the chemicals on the nest.  Standing directly below a nest increases one's risk of being stung. So make sure you are not standing just below the nest. All paper wasp should be died instantly after getting contacted by the insecticide. However you should wait for some time and then check if there any insects left. When you are confirm that all the insects are died, just scrape or knock down the nest.

Like humans, the paper wasp has a special talent for face recognition

University of Michigan evolutionary biologist and one of her graduate students have found that humans and paper wasps have evolved a very similar face-learning mechanism.

 "Wasps and humans have independently evolved similar and very specialized face-learning mechanisms, despite the fact that everything about the way we see and the way our brains are structured is different," said graduate student Michael Sheehan, who worked with evolutionary biologist Elizabeth Tibbetts on the face-recognition study. "That's surprising and sort of bizarre."

During the study, twelve paper wasp were trained to discriminate between two different images mounted inside a T-maze.  The paired images included photos of normal paper wasp faces, photos of caterpillars, simple geometric patterns, and computer-altered wasp faces. The researchers observed that the paper wasps, which are generalist visual predators of caterpillars, were able to differentiate between two unaltered paper wasp faces faster and more accurately than a pair of caterpillar photos, two different geometric patterns, or a pair of computer-altered wasp faces.

"This shows that the way they learn faces is different than the way they seem to be learning other patterns. They treat faces as a different kind of thing," Sheehan said.

"Humans have a specialized face-learning ability, and it turns out that this wasp that lives on the side of your house evolved an analogous system on its own," he said. "But it's important to note that we're not claiming the exact process by which wasps learn faces is the same as humans."
