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

Anaishi

Akidunga

Kwangua mwiba wa nyuki na upoze mahali hapo.
Mtu akipata shida ya kupumua, uso au koo likivimba, au akijisikia kuzimia, hiyo ni dharura ya mzio: piga namba ya dharura na umtumie kalamu yake ya adrenalini kama anayo.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Akikudunga: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama
