Fight back against those pesky mosquitoes

That nasty pest, the mosquito
That nasty pest, the mosquito

Like it or not, along with the balmy sunny days of summer come nasty biting insects, like ticks, no-see-ums, black flies, and mosquitoes. It just doesn’t seem fair that they like to hang out in the same campsites and on the same trails that we RVers do. And if their itching reminders of their bites weren’t enough, they can also make us sick and spread disease.

Most people do not get sick from a few mosquito or tick bites, but some mosquitoes and ticks can carry viruses that cause human illnesses, like West Nile Virus, symptoms of which can include headaches, joint pains, rashes, and though rarely, neurological symptoms and some deaths. The CDC says there are about 30,000 reported cases each year, but but may be much larger.

Your risk depends largely on where you live and travel, says the CDC. About 96% of confirmed Lyme cases occur in just 13 states, mainly in the Northeast and Midwest, though mosquitoes that carry West Nile do live throughout the US. Often, local conditions determine where epidemics start. “For example, a 2012 outbreak near Dallas was spurred by drought”, says USA Today, “which caused virus-carrying mosquitoes and birds to cluster around scarce water sources. Another outbreak in Arizona was linked to un-drained swimming pools in foreclosed houses abandoned during the recession…”

One odd thing about these pesky insects, just like people, they sometimes find some people more attractive than others. Jonathan Day, a professor of medical entomology at the University of Florida, is convinced it’s mostly about carbon dioxide, which mosquitoes and ticks can detect and is how they find their victims. Some people produce more CO2 than others, like heavier people, pregnant women, and exercisers. “The amount of carbon dioxide you produce depends on your metabolic rate,” he says.

But Uli Bernier, a research chemist for the U.S. Department of Agriculture, says he has seen evidence that other factors are at work over many years of exposing people to mosquitoes in his Gainesville, Fla., lab. He’s seen different mosquitoes zero in on different people. It has also been found that some people seem to become more attractive to mosquitoes over time, and alcohol, in particular, seems to attract mosquitoes. So if you are a 250-pound weight lifting pregnant RVer and you just finished your heavy weight workout in your campsite and are chilling out with a beer, look out, you will be the mosquitoes’ number one target.

Some repellents work well, others don’t.

CDC says you want one that includes DEET (N,N-diethyl-meta-toluamide), picaridin, oil of lemon eucalyptus, or a chemical called IR3535 are effective. But while DEET products have long been thought to be the most effective, recent tests by Consumer Reports gave the edge to picaridin and oil of lemon eucalyptus.

These tips can also help.

Wear long sleeves, pants, closed shoes and socks for a walk in the woods.
Spray a repellent called permethrin on clothing and gear.
Check yourself for ticks when you go inside.
For around your campsite, sit next to a fan as mosquitoes perform poorly in a wind, losing the ability to fly well.

These repellent strategies do not seem to work:

“Natural” repellent sprays made with plant oils, such as citronella, lemongrass, and rosemary
Wrist bands containing citronella or geraniol oil
Citronella candles

The American Academy of Pediatrics adds these to the ineffective list:

Vitamin B1 supplements
Bug zappers (they may actually attract insects)
Ultrasonic devices
