A bite is painful and may happen if the bug is handled or disturbed. It prefers to avoid people rather than confront them.1

Hufanya nini akiogopa?

When disturbed, it first tries to escape or play dead, then raises its front legs and hind end in a fighting stance, and may latch on and bite.1

Akiuma

Kwa manyoya ya kiwavi yanayowasha: yaondoe kwa utepe unaonata, kisha osha ngozi. Usisugue.
Kwa kuumwa: osha na upoze. Tafuta msaada wa kitabibu mtu akijisikia vibaya au akivuja damu kwa urahisi.

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.
Akikuuma: 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

Adults survive winter by burrowing under mud and leaf litter.1
