Who's At Risk
Insect bites and stings are a problem in all regions of the world for people of all ages. In the Midwest and East Coast regions of the US, mosquitos, flying insects, and ticks account for most bites. In drier areas of the Western US, crawling insects are more of a problem.

There is no proven effect on race or sex in terms of bite reactions. However, some individuals clearly appear more attractive to insects, perhaps related to body heat, odor, or carbon dioxide excretion.

Severe allergic reactions to stings occur in .5–5% of the US population.
