August is peak mosquito season, and California’s in a fight against disease some carry

Bugged out

We all love to spend the summer months outside, but the warmest months also bring out more bugs, some of which may carry nasty diseases.

According to the Centers for Disease Control and Prevention, over 200 types of mosquitoes live in the continental United States and U.S. territories and about 12 types spread germs that can make people sick.

In California, there are approximately 50 kinds of mosquitoes with about six that carry harmful diseases such as West Nile virus, Zika, dengue and yellow fever viruses. Some infect horses, birds and house pets.

Some studies claim mosquitoes are the world’s deadliest animal and estimates say they kill 700,000 people a year, with most in Sub-Saharan Africa.

How they find us

Body odors, exhaled breath and body heat all alert mosquitoes to a person’s presence. The bugs pick up scents through olfactory neurons on their antennae—they can smell body odor from nearly 200 feet away —and use body heat to zero in on their target.

Recent studies have shown more mosquitoes seemed to prefer people whose scent contained a blend of carboxylic acids, the oily secretions that hydrate and protect our skin. Two of those carboxylic acids are also found in Limburger cheese, known to lure mosquitoes.

What keeps them away

Mosquitoes are less likely to buzz over to scents with lots of the chemical eucalyptol, found in plants like sage and eucalyptus trees. The EPA has a list of recommended repellents including DEET, Picaridin, IR3535 and others with eucalyptus oils.

The EPA has a webpage on how to find the right repellent for you here.

In addition to repellent, wearing loose-fitting long pants and sleeves while outdoors is helpful to prevent bites and so are screens on windows and doors.
