The bald-faced hornet is a wasp with a striking black and white body and a white face. It builds large, hanging paper nests in trees and bushes across North America. Its workers will defend the nest by stinging repeatedly, so it is important to keep well away from its nests.1

Živi v

North America, including Canada, the Rocky Mountains, the western coast of the US and most of the eastern US. Most common in the Southeastern US.1

Moč strupa

Piki

Strup pride ven skozi želo.

Kaj naredi njen strup, ko ugrizne ali piči?

Workers can squirt venom from the stinger into the eyes of animals that intrude on the nest. The venom makes the eyes water immediately and causes temporary blindness.1

Kako nevarna je za ljudi?

It is aggressive when defending its nest. Workers sting repeatedly, and colonies can have 400 to 700 workers. The risk is highest when people walk too close to a nest or when a nest is built near homes.1

Če piči

Čebelje želo postrgaj ven in mesto ohladi.
Če ima poškodovanec težave z dihanjem, otekel obraz ali grlo ali se mu vrti, kot da bo omedlel, gre za nujno stanje zaradi alergije: pokliči številko za klic v sili in uporabi njegov adrenalinski avtoinjektor, če ga ima.

Ostani varen

Nikoli se ne dotikaj divje živali, je ne lovi in je ne draži, tudi če je majhna in tudi če je videti, kot da spi ali je mrtva.
Pusti ji prostor. Če jo srečaš, ostani miren, počasi stopi nazaj in jo pusti, da gre svojo pot.
Če te piči: ostani miren, ne premikaj se, pokliči številko za klic v sili (112, 000, 911) ali hitro pojdi v bolnišnico. Zapomni si, kako je izgledala, fotografija pomaga.

Ne preži nate. Strup uporablja, da ulovi hrano ali se zaščiti, in se veliko raje skrije. Več o varnosti

Dejstva

It can spray venom from its stinger into the eyes of nest intruders, causing temporary blindness.1

Its colony can have 400 to 700 workers, the largest recorded colony size in its genus, Dolichovespula.1

Female bee moths can lay eggs in its nests, and the hatched larvae feed on the eggs, larvae and pupae inside, sometimes destroying large parts of the nest.1

Its nests are made from chewed wood fibres mixed with saliva, which dries into a papery structure.1

A colony lasts about 4 months in Washington, from mid-May to mid-September. Colonies in lower latitudes last longer.1
