Less commonly (around 10% of Hymenoptera sting reactions), a large local reaction occurs when the area of swelling is greater than 10 centimetres (4 in). Rarely (1-3% of Hymenoptera sting reactions), systemic reactions can affect multiple organs and pose a medical emergency, as in the case of anaphylactic shock. [2] [3]
Insect sting allergy is the term commonly given to the allergic response of an animal in response to the bite or sting of an insect. [1] Typically, insects which generate allergic responses are either stinging insects ( wasps , bees , hornets and ants [ 2 ] ) or biting insects ( mosquitoes , ticks ).
Symptoms following the attack can range from inflammatory reactions to severe allergic reactions resulting in anaphylactic shock. In some cases, death may occur following several stings and a large amount of venom injection; however, a wasp sting typically will not produce a reaction more severe than local symptoms that affect only the skin.

[67] [68] [69] Wasp nests made in or near houses, such as in roof spaces, can present a danger as the wasps may sting if people come close to them. [70] Stings are usually painful rather than dangerous, but in rare cases, people may suffer life-threatening anaphylactic shock. [71]
Anaphylactoid reaction, non-immune anaphylaxis, or pseudoanaphylaxis, is a type of anaphylaxis that does not involve an allergic reaction but is due to direct mast cell degranulation. [ 10 ] [ 42 ] Non-immune anaphylaxis is the current term, as of 2018, used by the World Allergy Organization [ 42 ] with some recommending that the old ...
For minor sting injuries, with symptoms only including pustule formations and pain, over-the-counter products are available to prevent infection. Ants should be removed by washing the area with antiseptic soap, and itchiness. It is rare for ant sting sites to become infected, so the use of antibiotic prophylaxis is not always required.
