如果牠咬人

被會螫人的毛毛蟲毛刺到時：用膠帶把毛黏起來，再清洗皮膚。不要搓揉。
被咬時：清洗並冷敷。如果傷者覺得不舒服或容易流血，要就醫。

一定要先打緊急電話（112、000、911）。這是一般急救指引，不是醫療建議。急救基本知識

注意安全

絕對不要碰、抓或捉弄野生動物，就算是很小的動物，就算牠看起來在睡覺或已經死了也一樣。
給牠空間。如果遇到了，保持冷靜，慢慢往後退，讓牠自己離開。
如果被牠咬了：保持冷靜，保持不動，打緊急電話（112、000、911）或趕快去醫院。記住牠的樣子，有照片會很有幫助。

牠不是想來抓你。牠用毒液來捕捉食物或保護自己，而且牠更想躲起來。更多安全知識

小知識

Its venom is toxic to methicillin-resistant Staphylococcus aureus, a type of bacteria that resists many antibiotics.1

It can hitch a ride on bats, flies and hymenopterans (a group of insects that includes bees, wasps and ants).1

Males keep small territories a few centimetres across, and a male performs a mating dance when a female enters.1

It usually lives for three or four years.1
