Are bee sting allergies hereditary?Not in any clear way. Allergic parents pass on a tendency to allergy in general, but researchers have not found a strong genetic link for sting allergy specifically. Most people with a severe sting reaction have no family history of it.
Will every sting cause anaphylaxis once I have reacted?No. Only about 30 to 60 percent of people who had anaphylaxis from a sting react that way to the next one. The risk is still high enough to carry epinephrine and seek evaluation.
Which insects cause the most reactions?Honeybees, wasps, hornets, yellow jackets and fire ants. Insect allergy affects roughly 5 to 7.5 percent of people.
