Apa kesan bisanya?

Its venom contains neurotransmitters such as dopamine, serotonin, histamine and noradrenaline, along with enzymes, proteins such as melittin and bradykinin, and a neurotoxin called apamin, which attacks the nerves. In one documented case, a person developed tingling at the sting, headaches and shortness of breath, along with a fast, irregular heartbeat.1

Most stings do not need medical attention, but in rare cases they can be serious. In one documented case the victim needed hospital treatment, though that person may have been unusually sensitive to hornet and wasp stings.1

Apa yang ia buat apabila takut?

It stings when it is stepped on or grabbed and is defensive of its nest, and it may sting without warning when near its nest or food. When alarmed, it performs a dance outside the nest with loud buzzing, darting in and out, and attacking or approaching the target.1

Jika ia menyengat

Most stings do not require medical attention. In rare serious cases, hospital treatment is needed; in one documented case, electrical cardioversion or the drug propafenone were effective treatments for the heart reactions.1
