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 ).
It is now possible to purchase sun block that could prevent or decrease symptoms of stings. [5] Wet suits and foot wear can also be protective. [7] Avoid swimming in areas in which you can see jellyfish in the water. [8] Check about any warnings prior to entering the water. [7] Do not handle dead or beached jellyfish on the beach. [9]

The reaction is usually seen 2–24 hours after the original reaction. [88] Cytokines from mast cells may play a role in the persistence of long-term effects. Late-phase responses seen in asthma are slightly different from those seen in other allergic responses, although they are still caused by release of mediators from eosinophils and are ...
When bees sting, they inject a venom that’s mostly water. This allows easy dispersal of the venom, especially if they sting in moist tissue, which we have lots of. For example, our skin and ...
Depending on the size of the stingray, humans are usually stung in the lower limb region. [2] Stings usually occur when swimmers or divers accidentally step on a stingray, [3] but a human is less likely to be stung by simply brushing against the stinger. Those who enter waters with large populations of stingrays are advised to slide their feet ...
Stings are usually located at the rear of the animal. Animals with stings include bees, wasps (including hornets), some ants like fire ants, and scorpions, [2] [3] as well as a single beetle species (Onychocerus albitarsis) that can deliver a venomous sting from its antennae, whose terminal segments have evolved to resemble a scorpion's tail.

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]
