More Than Just a Summer Nuisance

Summer at Valor brings warmer and humid weather, longer afternoons, and, lately, plenty of mosquitoes. Whether one finds its way into a dorm room or appears while students are outside, mosquitoes can quickly become one of summer's most annoying visitors. But behind the buzzing and itching is a surprisingly complex biological process, and a public-health concern that extends far beyond campus.

Only female mosquitoes bite humans. They need nutrients from blood to develop their eggs, while males primarily feed on plant nectar. When a female bites, she releases saliva containing proteins that prevent blood from clotting. Our immune system reacts to these proteins, creating the familiar itchy, red bump.

More importantly, some mosquito species can act as vectors, carrying pathogens between hosts and transmitting diseases such as dengue, malaria, and Japanese encephalitis.

Mosquitoes are especially common in warm weather because temperature affects their activity and reproduction. Outside of campus, places like local parks, gardens, and areas around homes can provide breeding environments when rainwater collects in containers, drains, or other small spaces.

So this summer, when heading home or spending time outdoors, remember that mosquito prevention is not just about avoiding an itchy bite; it is also a small part of protecting community health.
