How Disney World keeps out mosquitos

Disney World is largely mosquito-free, thanks to civil engineer Joe Potter

As a former governor of the mosquito-prone Panama Canal zone, Potter understood the danger of standing water. At Disney, Potter built ditches to reduce moisture, designed buildings to channel water away, and more. His efforts help visitors avoid bites, adding to the perceived magic of the magical kingdom.

Disney World's Magic Kingdom includes an underground utilidor

Walt Disney viewed everything happening in his parks as a performance and didn't like it when that performance was disrupted by necessary aspects of the park's maintenance, like trash collection. With Florida's Disney World, the company corrected that problem by building a massive area underneath the park to be used as a "backstage."

Explore inside a mosquito factory where millions of mosquitoes are bred weekly

In Medellin, Colombia, scientists are infecting Aedes aegypti mosquitoes with Wolbachia, a bacterium that wouldn't otherwise infect the species, but does block its ability to transmit dengue, Zika, yellow fever, and chikungunya. In the wild, infected mosquitoes would breed with wild mosquitoes, pass down Wolbachia, and thus reduce disease transmission.

Iceland, the last mosquito-free country, detected them in 2025

Recently several of the mosquito species Culiseta annulata were documented in Iceland—the last country that had not yet seen them, underscoring that climate change is shifting the bugs' patterns. Mosquitoes can hide out in human structures to survive icy temperatures. The bugs are now known to live everywhere except the continent of Antarctica.

Disney World was originally known as the 'Florida Project'

Between 1964 and 1965, Disney quietly bought over 27,000 acres under fake names to keep prices low. But when the Orlando Sentinel exposed the scheme, Disney had to go public—forever changing Florida’s tourism industry.

Mosquitoes stop flying at wind speeds equivalent to the swishing of a horse's tail

This low-threshold for wind—halting flight at 2 to 3 miles per hour—underscores that the bugs are actually not particularly strong flyers. But they don't need to be particularly robust fliers since their tiny, dark bodies and erratic movements can make them challenging to spot.

Scientists still don't know why DEET is such an effective bug repellent

This chemical, used to keep ticks, fleas, mosquitoes, and other nuisance bugs away, is used by an estimated one-third of the US population and has been available to consumers since 1957. Researchers theorize that multiple mechanisms may be at work to deter bugs, including perhaps masking or confusing bugs' olfactory receptors.

Protecting yourself from West Nile involves avoiding getting bites and clearing standing water

The best prevention against West Nile is avoiding getting bit. That means covering your arms and legs with long, loose-fitting clothes, wearing insect repellant—on top of, not under sunscreen, and making your environment as inhospitable to mosquitoes as possible, including clearing any standing water.

Read the 2012 study about captive orcas and the threat of mosquito-borne illness

Written by orca trainers who went on to become scientists, it states mosquitoes bite orcas at night when the animals hang out close to the surface. What's more, antibiotics used to keep captive orcas healthy also may depress their immune response, boosting the risks of them being unable to fight off diseases like West Nile Virus and encephalitis, which have killed orcas at US water parks.

Mosquitoes top the ranking of the world's deadliest animals

Mosquitos kill about 760,000 people every year. The vast majority of those deaths are caused by malaria, which is transmitted and spread by the Anopheles mosquito. The second-place deadliest animal title goes to snakes, with an estimated human death toll of around 100,000 annually.

Disney Research developed a haptic interface where you can feel a fireworks display

Disney’s “Feeling Fireworks” uses water jets and a latex screen to replicate fireworks for blind individuals. Such technology may also provide inclusive experiences for the deaf community, though as of 2024, there are no plans to implement them in Disney parks.

Anopheles mosquitoes are developing resistance to insecticides

The malaria-transmitting mosquito species is developing resistance to the insecticides used in insecticide-treated bed nets and in indoor spraying in people's homes and communities. Malaria parasites are also developing resistance to antimalarial drugs.

Florida reports 71 imported malaria cases annually—4% of all the US cases

The Sunshine State reports an average of 71 imported malaria cases annually. Malaria isn't endemic to Florida but mosquitoes in the state are biologically capable of transmitting the disease from one infected person to another noninfected person.

Understanding the Disney adult phenomenon

Disney isn’t just for kids, at least according to Disney adults, who dress up as their favorite characters and make pilgrimages to the company’s parks. They’re often considered immature, unrefined, or worse, but the members of this subculture don’t see anything wrong with their passionate devotion to Disney. This article explores the phenomenon through interviews with actual Disney adults, offering a more nuanced take on the reasons behind the much-maligned trend.

Disney keeps one street in Burbank pristine for shooting suburban scenes

Nearly every home on Keystone Street is owned by Disney and is often used when the company shoots movies set in idyllic suburbs. Even non-Disney projects, like the horror classic "Halloween," have used the street for filming.

Disney was saved by 'Cinderella,' which brought the company out of debt

Producing war propaganda and training films helped the company towards solvency, but the military content wasn't a cure-all. Disney wasn't in the clear until 1950's "Cinderella," a much-needed hit. The movie's success was largely due to the return of the company's best writers and the work of Mary Blair, a watercolor artist who brought a more whimsical style to the film.

The original Mickey Mouse's copyright has expired, but Disney still owns the trademark

In 2024, "Steamboat Willie"—the 1928 Walt Disney animation with the first depiction of Mickey Mouse—entered the public domain. While anyone is free to build on the original characters and storyline of "Steamboat Willie," Disney still owns the trademark for Mickey Mouse, so any branding with the character's depiction that appears to be from Disney is off-limits.

The most effective method of managing invasive species is prevention education

Controlling a spread after a species has become established in an area is much more costly and time-consuming than early detection and rapid response. Control methods include the purposeful introduction of predators, the use of pesticides, herbicides, fungicides, and insecticides, and physical collection and removal.

Biologists have become regular fixtures at Turkey Point Nuclear Plant, where crocodiles found refuge after Florida's population boom pushed them out of coves and mangrove swamps. Teams working on the plant have done their part to modify the land and help the species thrive.

How Guam became an island of snakes and spiders

The US territory of Guam has 40 times the number of spiders of nearby islands, and a voracious collection of snakes which has nearly emptied it of any native birds. Researchers took it upon themselves to count the species and determine what turned the island into such a haunt of arachnids and serpents, where walking into the woods can mean navigating endless layers of spider webs.
