Typically surfacing in late summer and early fall, West Nile is caused by mosquitoes feeding on infected birds, and then passing the virus to humans and other animals through the saliva they inject with their bites.

What Happens When a Mosquito Bites?

Most of us are familiar with what a mosquito bite looks and feels like – a red itchy welt that, depending on the individual, can become swollen and irritated. But have you ever wondered why this happens? What does a mosquito do when it lands on you and why do we often not even feel it happen?

We caught up with Hope Bowman, Entomologist B.C.E, to glean some knowledge in regard to this popular summertime pest.

She explained that there are two main things mosquitoes do when they bite you:

• Their saliva acts like Novocain, making it so we don’t feel it when they bite us.
• They use an anti-coagulant that makes it so the blood does not clot.

The allergic reaction we experience is directly related to the saliva of the mosquito bite.
