Mosquitoes can ruin a hike. Here's how to stop them

The hoot of a great horned owl. The munching of a mule deer enjoying grass. The crunching of your feet on the sandy soil. To any hiker, these sounds enhance the joy of being outdoors. But the endorphin rush of a great trail can be blunted by the high-pitched buzz of a mosquito hovering around your neck, trying to score some lunch.

Unfortunately, Southern California’s mosquito season began in early May and there’s no end in sight. This period has grown “longer and longer” according to Susanne Kluh, general manager at Greater Los Angeles County Vector Control District.

“When I started at the district 25 years ago, we pretty much put our [tracking and collection] tools away in the middle of October,” Kluh said. “Now because it stays warm so long, [mosquito season] really goes into late November, sometimes early December.”

Being bitten by a mosquito can result in an itchy, unsightly red bump and — depending on where you are — serious disease. Outbreaks of dengue fever have been seen this year in several countries in Latin America and the Caribbean, underscoring the importance of wearing repellent regardless of where you spend time outdoors.

So I’ve put together an explainer on how to protect yourself while re-creating in Southern California. Trust me, it will come in handy when planning your next camping trip or hike!

First off, what kinds of mosquitoes inhabit L.A.?

Too many. Los Angeles County is home to several types of mosquitoes, including multiple kinds of culex mosquitoes that spread West Nile virus, usually in the summer months.

Two of the most notorious are the invasive ankle-biting yellow fever mosquito (Aedes aegypti) and Asian tiger mosquito (Aedes albopictus), Kluh said.

Since the 1940s, these little jerks have repeatedly made their way to Southern California. And that includes a large infestation of Asian tiger mosquitoes in 2001 that came over with an ornamental bamboo shipment imported from China. For years they struggled to get established. Then climate change worsened and the Aedes mosquitoes likely adapted. “Every time they live somewhere, they get a little more used to a climate,” Kluh said.

In 2011, L.A. County officials discovered the Asian tiger mosquito in El Monte, which raised alarm bells because of its ability to carry serious illnesses, including dengue and yellow fever in humans, and heartworm in dogs, according to the UC Riverside Center for Invasive Species Research.

Then in 2014, yellow fever mosquitoes were discovered in Commerce and Pico Rivera, which raised similar health concerns. Despite its name, the yellow fever mosquito isn’t transmitting the disease in L.A. County. (But it could if it ever found an infected local host.)

Both species are now established in the L.A. metro area, and we’ve suffered since.

These aggressive daytime biters spread serious diseases outside L.A. like Zika virus, which can cause birth defects among pregnant patients, Chikungunya, which can cause serious long-term joint pain and dengue fever, which can cause high fever and body aches, and occasionally, death.

But all mosquitoes aren’t dangerous. Young mosquitoes generally don’t carry disease and are simply a nuisance. They’re also great snacks for many birds.

Where do they lay their eggs?

The Southern house mosquito, a type of Culex mosquito, typically lays its eggs in fresh or stagnant water, like a muddy puddle where a seasonal river once flowed. She’ll lay them all at once, creating a raft of 100 to 300 eggs floating on the surface of the water, according to the Centers for Disease Control and Prevention.

Meanwhile, the Aedes mosquitoes lay durable eggs that can sit attached to, for example, a dry water trough. Once hit with a little rain, those eggs hatch.

They “love biting people,” and can breed in tiny places, Kluh said. A beer bottle cap, left by an imprudent camper next to a campfire, is the perfect hatching nook for any L.A. Aedes girl.

Typically, trails with water will attract mosquitoes, as that’s where they go to lay their eggs. The Culex thriambus enjoys areas along rivers and streams in foothill communities. You might also find the Western treehole mosquito (Ochlerotatus sierrensis) on a trail, especially one nearby oak trees. These guys can carry heartworm, which can be devastating to a dog that hasn’t been treated with preventive medicine.

In higher elevations, including parts of the High Sierra, you might even find snowmelt mosquitoes, which breed in puddles left from melting snow. They don’t carry West Nile virus but do enjoy biting people.

Wow, gross! How do I keep them away?

There are several ways you can protect yourself from mosquitoes. The most effective of them is DEET.

DEET (chemical name, N,N-diethyl-meta-toluamide) is the active ingredient in many insect repellents on the market. It was developed by the U.S. Army in 1946 and then registered for public use in 1957, according to the National Library of Medicine.

The concentration of DEET in a product determines how long it will keep mosquitos away. A product with 10% DEET will protect you for about two hours while a 30% DEET product provides about five hours of protection.

As mosquitoes age, their olfactory system becomes less sensitive, according to Walter S. Leal, a UC Davis distinguished professor in molecular and cellular biology who has researched insects for more than 30 years and studied the effectiveness of DEET and other insect repellents.

So, to ward off disease-carrying older mosquitoes, you’ll need a higher percentage of DEET — somewhere between 20% to 30%.

Researchers have developed other insect repellents, but they never last as long as DEET. That being said, if you’re going to the playground with your child for 30 minutes, Leal says that citronella spray — which is distilled from grass varieties — should work just fine. But if you’re going on a long hike, DEET is the only repellent on the market proven to last up to six hours. “That’s why it is so difficult to beat,” Leal said.

But is DEET safe?

The short answer? Yes. But that yes comes with an asterisk: According to the American Academy of Pediatrics, kids should use insect repellents that contain no more than 30% DEET. (It notes that reports of adverse effects associated with DEET are rare, and when used appropriately, DEET does not present a health risk.)

The CDC recommends using insect repellent, including DEET, if you’re pregnant or nursing. Repeated research has found that DEET is safe for pregnant parents when used as directed.

“[DEET] is the gold standard,” Leal said.

In his lab, he’s tested products with 20% DEET versus products with 20% Picaridin, a synthetic compound developed in the 1980s to resemble the natural piperine, which is found in plants used to make black pepper. Through that work, Leal said he and other scientists have never found a product more long-lasting and overall effective at warding off mosquitoes than DEET.

But DEET has a perception problem because unlike some repellents, it isn’t naturally occurring, Leal said. The public, especially the naturally inclined, take pause with that.

“They want something that’s natural — they forget that strychnine [and] ricin are all natural products,” Leal said, referencing poisons derived from plants. “Being natural does not necessarily mean it is good, and being synthetic doesn’t necessarily mean it is bad.”

Additionally, people often incorrectly associate DEET with the banned insecticide DDT. “This is a big mistake,” Leal said.

There is no chemical similarity between the two. DEET isn’t a pesticide, meaning it repels insects but does not kill them.

But can’t my clothes protect me?

Sure they can. While on a hike, wear loose-fitting long-sleeve shirts and pants. You can also invest in clothing treated with insecticide permethrin, or buy a spray with permethrin for treating your tent, gear or clothing (while you’re not wearing it) to help ward off mosquitoes. It is not effective to spray DEET on your clothing, Leal said.

But unless you wear a full-body hazmat suit doused in permethrin, your exposed skin will still be a target for mosquitoes.

OK, fine, I’ll use DEET. How should I apply it?

When wearing both sunscreen and repellent, apply repellent last. If you apply sunscreen last, it will cover the repellent, and mosquitoes will not sense it, Leal said.

Generally, it’s most helpful to apply DEET on bare skin — your neck, hands, ankles, whatever skin is showing. It’s not recommended to use repellent under clothing.

It’s important to remember to reapply repellent as needed, as even DEET will wear off over time.

Anything else I should know?

A mosquito bite here and there is inescapable, but as long as you’re vigilant and embrace the DEET, you will be able to prevent your flesh from becoming lunch.

And keep in mind, the repellent you apply to keep mosquitoes away will also help ward off the other nasties like ticks and black flies. Three pests, one spray!

Found: The 19th century silent film that first captured a robot attack

A screenshot from George Mélière’s Gugusse et l’Automate. The pioneering French filmmaker’s 1897 short, which likely features the first known depiction of a robot on film, was thought lost until it was found among a box of old reels that had belonged to a family in Michigan and restored by the Library of Congress.

The Frisbee Collection/Library of Congress

The Library of Congress has found and restored a long-lost silent film by Georges Méliès.

The famed 19th century French filmmaker is best known for his groundbreaking 1902 science fiction adventure masterpiece Le Voyage dans la Lune (A Trip to the Moon).

The 45-second-long, one-reel short Gugusse et l’AutomateGugusse and the Automaton – was made nearly 130 years ago. But the subject matter still feels timely. The film, which can be viewed on the Library of Congress’ website, depicts a child-sized robot clown who grows to the size of an adult and then attacks a human clown with a stick. The human then decimates the machine with a hammer.

In an Instagram post, Library of Congress moving image curator Jason Evans Groth said the film represents, “probably the first instance of a robot ever captured in a moving image.” (The word “robot” didn’t appear until 1921, when Czech dramatist Karel Čapek coined it in his science fiction play R.U.R..)

“Today, many of us are worried about AI and robots,” said archivist and filmmaker Rick Prelinger, in an email to NPR. “Well, people were thinking about robots in 1897. Very little is new.”

A long journey

Groth said the film arrived in a box last September from a donor in Michigan, Bill McFarland. “Bill’s great grandfather, William Frisbee, was a person who loved technology,” Groth said. “And in the late 19th century, must have bought a projector and a bunch of films and decided to drive them around in his buggy to share them with folks in Pennsylvania, Ohio, New York.”

McFarland didn’t know what was on the 10 rusty reels he dropped off at the Library of Congress’ National Audio-Visual Conservation Center in Culpeper, Va. A Library article about the discovery describes the battered, pre-World War I artifacts as having been, “shuttled around from basements to barns to garages,” and that they, “could no longer be safely run through a projector,” owing to their delicate condition. “The nitrate film stock had crumbled to bits on some; other strips were stuck together,” the article said. It was a lab technician in Michigan who suggested McFarland contact the Library of Congress.

“The moment we set our eyes on this box of film, we knew it was something special,” said George Willeman, who heads up the Library’s nitrate film vault, in the article.

Willeman’s team carefully inspected the trove of footage, which also contained another well-known Méliès film, Nouvelles Luttes extravagantes (The Fat and Lean Wrestling Match) and parts of The Burning Stable, an early Thomas Edison work. With the help of an external expert, they identified the reel as having been created by Méliès because it features a star painted on a pedestal in the center of the screen – the logo for Méliès Star Film Company.

A pioneering filmmaker

Méliès was one of the great pioneers of cinema. The scene in which a rocket lands playfully in the eye of Méliès’ anthropomorphic moon in Le Voyage dans la Lune is one of the most famous moments in cinematic history. And he helped to popularize such special effects as multiple exposures and time-lapse photography.

This moment from George Méliès' Le Voyage dans la Lune (A Trip to the Moon) is considered to be one of the most famous in cinematic history.

Presumed lost until the Library of Congress’s discovery, Gugusse et L’Automate loomed large in the imaginations of science fiction and early cinema buffs for more than a century. In their 1977 book Things to Come: An Illustrated History of the Science Fiction Film, authors Douglas Menville and R. Reginald described Gugusse as possibly being, “the first true SF [science fiction] film.”

“While it may seem that no more discoveries remain to be made, that’s not the case,” said Prelinger of the work’s reappearance. “Here’s a genuine discovery from the early days of film that no one anticipated.”

‘The Fall and Rise of Reggie Dinkins’ falls before it rises — but then it soars

Tracy Morgan, as a presence, as a persona, bends the rules of comedy spacetime around him.

Consider: He’s constitutionally incapable of tossing off a joke or an aside, because he never simply delivers a line when he can declaim it instead. He can’t help but occupy the center of any given scene he’s in — his abiding, essential weirdness inevitably pulls focus. Perhaps most mystifying to comedy nerds is the way he can take a breath in the middle of a punchline and still, somehow, land it.

That? Should be impossible. Comedy depends on, is entirely a function of, timing; jokes are delicate constructs of rhythms that take time and practice to beat into shape for maximum efficiency. But never mind that. Give this guy a non-sequitur, the nonner the better, and he’ll shout that sucker at the top of his fool lungs, and absolutely kill, every time.

Well. Not every time, and not everywhere. Because Tracy Morgan is a puzzle piece so oddly shaped he won’t fit into just any world. In fact, the only way he works is if you take the time and effort to assiduously build the entire puzzle around him.

Thankfully, the makers of his new series, The Fall and Rise of Reggie Dinkins, understand that very specific assignment. They’ve built the show around Morgan’s signature profile and paired him with an hugely unlikely comedy partner (Daniel Radcliffe).

The co-creators/co-showrunners are Robert Carlock, who was one of the showrunners on 30 Rock and co-created The Unbreakable Kimmy Schmidt, and Sam Means, who also worked on Girls5eva with Carlock and has written for 30 Rock and Kimmy Schmidt.

These guys know exactly what Morgan can do, even if 30 Rock relegated him to function as a kind of comedy bomb-thrower. He’d enter a scene, lob a few loud, puzzling, hilarious references that would blow up the situation onscreen, and promptly peace out through the smoke and ash left in his wake.

That can’t happen on Reggie Dinkins, as Tracy is the center of both the show, and the show-within-the-show. He plays a former NFL star disgraced by a gambling scandal who’s determined to redeem himself in the public eye. He brings in an Oscar-winning documentarian Arthur Tobin (Radcliffe) to make a movie about him and his current life.

Tobin, however, is determined to create an authentic portrait of a fallen hero, and keeps goading Dinkins to express remorse — or anything at all besides canned, feel-good platitudes. He embeds himself in Dinkins’ palatial New Jersey mansion, alongside Dinkins’ fiancée Brina (Precious Way), teenage son Carmelo (Jalyn Hall) and his former teammate Rusty (Bobby Moynihan), who lives in the basement.

If you’re thinking this means Reggie Dinkins is a show satirizing the recent rise of toothless, self-flattering documentaries about athletes and performers produced in collaboration with their subjects, you’re half-right. The show feints at that tension with some clever bits over the course of the season, but it’s never allowed to develop into a central, overarching conflict, because the show’s more interested in the affinity between Dinkins and Tobin.

Tobin, it turns out, is dealing with his own public disgrace — his emotional breakdown on the set of a blockbuster movie he was directing has gone viral — and the show becomes about exploring what these two damaged men can learn from each other.

On paper, sure: It’s an oil-and-water mixture: Dinkins (loud, rich, American, Black) and Tobin (uptight, pretentious, British, practically translucent). Morgan’s in his element, and if you’re not already aware of what a funny performer Radcliffe can be, check him out on the late lamented Miracle Workers.

Whenever these two characters are firing fusillades of jokes at each other, the series sings. But, especially in the early going, the showrunners seem determined to put Morgan and Radcliffe together in quieter, more heartfelt scenes that don’t quite work. It’s too reductive to presume this is because Morgan is a comedian and Radcliffe is an actor, but it’s hard to deny that they’re coming at those moments from radically different places, and seem to be directing their energies past each other in ways that never quite manage to connect.

It’s one reason the show flounders out of the gate, as typical pilot problems pile up — every secondary character gets introduced in a hurry and assigned a defining characteristic: Brina (the influencer), Rusty (the loser), Carmelo (the TV teen). It takes a bit too long for even the great Erika Alexander, who plays Dinkins’ ex-wife and current manager Monica, to get something to play besides the uber-competent, work-addicted businesswoman.

But then, there are the jokes. My god, these jokes.

Reggie Dinkins, like 30 Rock and Kimmy Schmidt before it, is a joke machine, firing off bit after bit after bit. But where those shows were only too happy to exist as high-key joke-engines first, and character comedies second, Dinkins is operating in a slightly lower register. It’s deliberately pitched to feel a bit more grounded, a bit less frenetic. (To be fair: Every show in the history of the medium can be categorized as more grounded and less frenetic than 30 Rock and Kimmy Schmidt — but Reggie Dinkins expressly shares those series’ comedic approach, if not their specific joke density.)

While the hit rate of Reggie Dinkins‘ jokes never achieves 30 Rock status, rest assured that in episodes coming later in the season it comfortably hovers at Kimmy Schmidt level. Which is to say: Two or three times an episode, you will encounter a joke that is so perfect, so pure, so diamond-hard that you will wonder how it has taken human civilization until 2026 Common Era to discover it.

And that’s the key — they feel discovered. The jokes I’m talking about don’t seem painstakingly wrought, though of course they were. No, they feel like they have always been there, beneath the earth, biding their time, just waiting to be found. (Here, you no doubt will be expecting me to provide some examples. Well, I’m not gonna. It’s not a critic’s job to spoil jokes this good by busting them out in some lousy review. Just watch the damn show to experience them as you’re meant to; you’ll know which ones I’m talking about.)

Now, let’s you and I talk about Bobby Moynihan.

As Rusty, Dinkins’ devoted ex-teammate who lives in the basement, Moynihan could have easily contented himself to play Pathetic Guy™ and leave it at that. Instead, he invests Rusty with such depths of earnest, deeply felt, improbably sunny emotions that he solidifies his position as show MVP with every word, every gesture, every expression. The guy can shuffle into the far background of a shot eating cereal and get a laugh, which is to say: He can be literally out-of-focus and still steal focus.

Which is why it doesn’t matter, in the end, that the locus of Reggie Dinkins‘ comedic energy isn’t found precisely where the show’s premise (Tracy Morgan! Daniel Radcliffe! Imagine the chemistry!) would have you believe it to be. This is a very, very funny — frequently hilarious — series that prizes well-written, well-timed, well-delivered jokes, and that knows how to use its actors to serve them up in the best way possible. And once it shakes off a few early stumbles and gets out of its own way, it does that better than any show on television.
