The Great Hornet is an animal belonging to the Yellow Hornet genus of the Hornet family. The female body is 30-35 millimeters long, with a brown head and a raised head. Hornets are distributed in Guangdong, Hainan Island, Guangxi and other places in China. The Chinese Journal of Medicinal Animals records that the Great Hornet "has the function of reducing swelling and detoxifying. It is mainly used for treating carbuncles, sores, and toxins, as well as spider and centipede bites." In summer and autumn, the Great Hornet is captured, boiled in boiling water, dried in the sun, and all adult insects are used as medicine or ground for later use. This product has the effects of detoxification, reducing swelling, and treating boils. It can be taken orally or applied externally. When faced with attacks or unfriendly disturbances, giant wasps will attack in groups, which can cause allergic and toxic reactions in the attacked animals.

Mosquitoes are small insects in the family Mosquitoidae of the order Diptera. There are approximately 3300 species of mosquitoes worldwide, with 400 species discovered in China. Mosquitoes are distributed around the world. Adults prefer to inhabit concealed, dark, and poorly ventilated places. Indoors, they often live under beds, behind cabinets, doors, in crevices in walls, as well as in animal pens and basements. Outdoors, they often live in grassy areas, caves, cellars, bridge openings, stone crevices, and other places. Female mosquitoes start sucking blood 2-3 days after eclosion, while male mosquitoes do not suck blood and feed on plant sap. Mosquitoes not only bite, suck blood, and disturb the human body, but also spread diseases. There are four mosquito borne diseases in China, namely dengue fever, Japanese encephalitis, malaria, and filariasis.
