蜇伤吃：什么都来一点

对人的危险: 很疼可能真的很疼，但几乎从不严重。

The black imported fire ant is a species of ant that is often called BIFA for short. It is native to South America but has spread to North America, where it has been found in several southern and south-eastern US states. Its sting can cause a red, swollen reaction, so it is useful to know it when you see one.1

怎样认出它

Black in colour, as its name says.1
Its sting leaves a sterile pustule (a small blister with no germs in it), surrounded by a red swelling.1

常被误认为： It was once thought to be a colour variety of the red imported fire ant (RIFA). It is now known to be a separate species with a different range and different living habits.1

毒液之力

蜇伤

毒液通过蜇刺出来。

它的毒液会造成什么？

Stings cause a sterile pustule surrounded by a raised, reddened swelling (wheal), with redness spreading beyond it (flare). The venom of this species may cause a more pronounced wheal and flare than the red imported fire ant.1

它对人有多危险？

对人的危险: 很疼可能真的很疼，但几乎从不严重。

How strong the reaction is depends on how many allergic (IgE) antibodies a person has already formed. People who have already built up these antibodies may react more strongly.1

如果它蜇人

清洗并冷敷蜇伤处。
如果这个人呼吸困难、脸或喉咙肿胀，或感觉要晕倒，这是过敏急症：拨打急救电话。

一定先拨打你的急救电话（112、000、911）。这里是一般急救指导，不是医疗建议。急救基础

注意安全

永远不要摸、抓或逗弄野生动物，即使是很小的，即使它看起来在睡觉或已经死了。
给它留出空间。如果遇到它，保持冷静，慢慢后退，让它走自己的路。
如果被它蜇了：保持冷静，保持不动，拨打你的急救电话（112、000、911）或尽快去医院。记住它长什么样，拍张照片会有帮助。

它不是冲着你来的。它用毒液捕猎或保护自己，而且它更愿意躲起来。更多安全知识

值得了解

事实

Black imported fire ants appear to be more tolerant of cold than the red imported fire ant, and they are less dominant.1

Its body contains more water than the red imported fire ant, which may be linked to the different regions where the two species live.1

For a long time it was thought to be either a subspecies or a colour variation of the red imported fire ant, but it is now recognised as its own species.1
