Welcome to Mosquito Season!

Spring has come and gone, now welcome to mosquito season. As you pack your bags for the beach house or the mountain campground don’t forget to pack light colored clothing with long sleeves, long pants and a bucket load or two of insect repellent.bestbuffettoonbyjoesanchez

How much we enjoy summer in North America depends a lot on how many mosquitoes there are waiting for us outside. Their bites are itchy and their buzzing annoying, but there’s also reason for concern; mosquitoes carrying dangerous diseases are lying in wait to use us as their next meal.

What causes mosquito populations to explode and shrink? Truthfully, it’s a combination of weather and climate — mosquitoes are very sensitive to their environment. Temperature and rainfall are two major predictors of mosquito populations, and this is for a good reason: These two factors have the greatest effect on their survival and ability to reproduce.

Mosquitoes like it warm and wet. Like most insects, mosquitoes are cold-blooded, or ectothermic.  Their body temperature closely matches the temperature of the environment (air or water) around them. If it is cold outside, they are cold. freezing-bugsIf it is warm outside, they are warm. Any time spent beyond their comfort zone can slow down or stop their development or even cause them to be injured and die.

There are more than 3,000 species of mosquitoes buzzing around on our planet, and a small handful of those actively feed from humans. And even then, only female mosquitoes feed on blood (required for egg production). The less intimidating males drink flower nectar.

Some mosquito species are far from being just bothersome, they carry dangerous diseases.  In North America, West Nile virus is carried by the Culex mosquito culex mosquitoand can cause serious health issues, including coma and paralysis. In tropical regions, mosquitoes are vectors of malaria, yellow fever, dengue, chikungunya and Zika viruses.  These debilitating diseases cause hundreds of thousands of deaths each year.  Two of the major offenders include the, Yellow fever mosquito or Aedes aegypti and the Asian tiger mosquito known as Ades albopictus

The most effective mosquito repellent to date, is Deet.  A repellant that contains 5 to 7 percent Deet will ward off the hungriest of mosquitoes.  Why is it so effective?  Because it tastes bad!  Researchers have found that Deet doesn’t leave a bad taste in a mosquitoes’ mouth, but on the tongue-like cells on their feet.

Now, when you’re outside, coated in DEET, realize this: You still smell good enough to eat. Mosquitoes still want to drink your warm, red blood.mosquito-in-red-sneekers-clipart-k5770244 But your skin tastes really, really gross…… to their feet.

Why Do Mosquitoes Love You? They think you’re HOT!

The two most dominant factors of mosquito attraction have to do with sight and smell, so there’s no brushing these guys (oops! Girls) off when they’re out looking for a quickie in the moonlight.

Here are four reasons a  Mosquito may pick you for the love of their life.

Your Fresh Breath

Mosquitoes don’t bite randomly. Instead, they find a victim by following their steady output of carbon dioxide.  Researchers say that mosquitoes are adept at figuring out where their target is by following trails of exhaled carbon dioxide.

Unfortunately, there is no way to cut down on your carbon dioxide emissions besides holding your breath. So, if you are being bitten you might want to head indoors.

Your Hot Body

While carbon dioxide is how mosquitoes lock onto you as a target, heat may be how they figure out the best place to bite you.

Dr. Jonathan Day, a professor of medical entomology at the University of Florida, tells us that before mosquitoes can take a bite they have to find an area of the body where the blood is closest to the surface. Common areas include the forehead, wrists, elbows, neck and ankles.woman-sweating

With the ever-increasing number of people keeping fit by exercising out of doors, mosquitoes are having an easier time finding what they love most, blood. Those who are over heated or who have just finished working out will have blood closer to the surface of the skin throughout their body. Faster respirations and an increase in carbon dioxide output identifies “Prime Targets” for love starved mosquitoes.

Exercising outdoors at dawn or dusk (prime time for mosquitoes) also ups the risk for more love bites.

Although a few small studies have speculated that mosquitoes were after specific blood types, the CDC says that’s false. By the time the mosquito bites you, they’ve picked you as their target.

Your Cool Outfit

Black may be the best color for a fashion statement and it’s great for hiding body flaws but it’s the worst for hiding from mosquitoes.

If you’re heading to an outdoor event and looking to avoid becoming a mosquito’s meal, avoid anything in dark denim or all-black outfits because some mosquitoes are visual hunters that search you out by looking for signs of life against the horizon. If you dress in dark colors, you stand out against the horizon and mosquitoes can see you.

Your Party Spirit

Movement can also draw these biting insects in, so gyrating party dancers and avid hikers on the move should wear plenty of bug-repellent.

Fact:

mosquito-no-more-deetEven though DEET has been the recommended repellent of choice, there are still those who look for a more natural solution to stop mosquitos from biting.  According to the CDC, lemon eucalyptus oil could be a much safer and more natural solution.  The CDC confirmed that lemon eucalyptus oil can be as effective as DEET in repelling mosquitoes.

Beach Bugs, They’re a Real Summer Bummer!

It’s Summer and the California beaches are the vacation destinations of millions of people.  It’s where we have fun in the sun, cool off in the water and relax on the sand under colorful umbrellas with cool drinks ansecluded-beachd our favorite books.

 

 

Reality check: what we often find are crowds, screaming kids, sand in awkward places, sunburn,  packed parking lots, traffic jams, and “Bugs”!

crowded-beachBe prepared to share your summer beach experience with these annoying, “Beach Bugs”.

Sand Fleas:  

sand-fleaThe common sand flea (Orchestia agilis), that is found on California beaches, is really an amphipod, or a small, shrimp-like crustacean. They burrow into the sand and they feed on decaying plant and animal matter that washes up on the shore, especially seaweed. They do not want anything to do with people. They obviously are not fleas, not even insects. However, they jump, similar to the way fleas do and they live in the sand, so hence the name sand flea.  On other beaches, around the world, different species of sand fleas present problems for humans, and other mamals, as they bite to gather blood in order to reproduce and carry diseases, not unlike mosquitoes.

Sand Flies:

sand-flies-on-legsThis is a general term that can be applied  to any biting fly you might encounter at the beach, besides a mosquito. This could even be a type of horsefly that is associated with that type of beachy habitat. Most commonly, the name sand fly refers to flies in the family Ceratopogonidae. These are small biting midges, sometines refered to as no-see-ums, only 1-4 millimeters in length that live in aquatic habitats all over the world. Like mosquitoes, it is only the female that sucks blood to get protein in preparation for laying her eggs. The bite itself is too small to feel. It’s not until later when your skin starts to react with the proteins in their saliva that you start to feel the itch, and oh brother, what an itch!

Salt Marsh Mosquitos: 

black-saltmarsh-mosquitoThe Aedes taeniorhynchus, commonly known as the black salt marsh mosquito, and the   Aedes sollicitans are frequent biters at Southern California Beaches.  They lay their eggs in brackish and saltwater pools left over from rising then receding tides. There is no mystery about these agressive ladies. They’re big, they’re hungry and they will come after you any time of the day whether you’re swatting at them or not. They are larger than many freshwater mosquitoes, so their bites are bigger too. In other parts of the world, they are vectors of Venezuelan and Eastern Equine Encephalitis. Luckily, in our area, this is not a problem, but they are a prime vector of dog heartworm, so if you live near the beach, keep your dogs on a heartworm preventative.

Sea Lice or Baby Jelly Fish (not bugs but they will bug you!)

What we callsea-lice-baby-jellyfish sea lice are actually larvae of jellyfish that float around in clouds in the ocean. Although they are tiny, they still possess those nasty stinging cells or nematocysts. If you’re swimming in the ocean, they can become trapped between your bathing suit and skin. This is when you can be stung. The stings cause intense itching and burning which result in a rash with small raised blisters.  The rash can last anywhere from two days to two weeks, but most of the time they go away with no medical attention necessary, just lots of cortisone cream and Benadryl! Prime time for ‘Sea Lice” is May through August.

So, grab your sunblock,  your bug repellent (with deet) and head out to the beach. Have fun, play safe and don’t let the “beach bugs” bite!  going-to-the-beach
