Description

Black-tailed hornet exhibits unique behaviours such as aerial hunting and construct multi-tiered combs for colony accommodation. These carnivorous insects prey primarily on other insects, feeding them to their larvae. Uncommon among wasp species, adult black-tailed hornet also consume insect prey instead of just nectar. Although the species poses a potential health risk due to painful stings, it tends not to be aggressive unless it feels threatened or its nest is disturbed.

What are the symptoms of a Black-tailed hornet bite or sting?

Localized Pain and Redness

A sting from black-tailed hornet typically leads to immediate localized pain and redness around the sting site. This is a typical reaction that usually dissipates after a few hours.

Swelling and Itching

Swelling at the sting site and generalized itching can occur. Some individuals may experience severe swelling, which is known as 'large local reaction'.

Allergic Reaction

Rarely, some individuals may experience an allergic reaction, known as anaphylaxis, characterized by difficulty breathing, dizziness, a rapid pulse, and hives. It's important to note that the severity of the symptoms can vary depending on the individual's sensitivity and the number of bites or stings received. If you are concerned about a specific bite or sting or if symptoms persist or worsen, it is recommended to consult a healthcare professional for proper evaluation and treatment.

Immediate Actions

For a black-tailed hornet sting, it's important to remain calm and limit physical activity to prevent venom from spreading. It's also suggested to remove the stinger, if present, as soon as possible using a card or similar flat object to scrap it off.

Washing the sting site with warm water and mild soap, then applying a cold pack can help reduce swelling and soothe the pain.
