Fire Ant's—Here's How to Avoid It

Fire Ant's—Here's How to Avoid It

Warnings of a potentially dangerous invasive ant have popped up on news sites and social media this week. You'd be forgiven for thinking a new threat had arrived. But this insect, the Asian needle ant (Brachyponera chinensis), is no newcomer—just a master of remaining inconspicuous.
The ant is getting attention after University of Georgia (UGA) entomologist Dan Suiter issued a warning that its sting can be remarkably painful and sometimes cause a serious allergic reaction called anaphylaxis. The ant is not new or spreading any faster than it used to, Suiter says. Rather, as a UGA Cooperative Extension entomologist, he's been getting calls about people being stung by the ant and needing hospital care. With summer in full swing, the insect is active, and people are likely to be in the woods or in their gardens where they might encounter it, prompting Suiter to raise awareness of the species.
'By this time last year, I had fielded three calls of people who had been stung by an Asian needle ant—they knew it was an Asian needle ant—and suffered anaphylaxis,' Suiter says. The problem, he adds, is that the insect is small, black and nondescript. 'You're not thinking that 'this tiny little creature right here could have consequences if it stung me.''

The Asian needle ant is native to Japan, Korea and China. It arrived in the U.S. around or before the 1930s, probably in ships carrying plants and livestock 'before we even realized that is a great way to spread things around,' says Theresa Dellinger, a diagnostician at the Insect Identification Lab at Virginia Tech. It's not clear precisely where the ant has spread within the U.S., but it's plentiful in the Southeast and appears to range as far north as Massachusetts, according to sightings on the community science app iNaturalist. It's not often seen farther west than Missouri, probably because it's not well-adapted to arid conditions, Dellinger says.
Studies have found that when Asian needle ants move into an area, they outcompete native ants, reducing ant diversity.
These ants don't lay down pheromone trails to lead their colony to food, so you won't see them marching in a line like the little black ant (Monomorium minimum). Instead, when an Asian needle ant finds food, it will return to its colony, pick up another worker and physically carry it to the jackpot, says Christopher Hayes, an entomologist at North Carolina State University.
And unlike fire ants, Asian needle ants don't build big nest mounds. Instead they love nesting in damp wood, such as fallen logs or wet mulch. While they aren't particularly aggressive, they will sting to protect their nest, making them a danger to the home gardener.
Their sting is initially more painful than a fire ant sting, Hayes says, but also irritatingly persistent, like fiberglass under the skin. The pain can also come and go. Hayes's two-year-old son recently got a sting. The little boy was fine after a few minutes, Hayes says, but then woke up after midnight that night crying about the pain again.
In their native range, Asian needle ant bites are associated with a 2 percent risk of anaphylaxis compared with a 0.5 to 1.5 percent risk from the bites of fire ants, Hayes says.
So how should you react if you see a suspected Asian needle ant on you? Gently flick or brush it off, Hayes and Suiter say. If it does sting you, try to capture the ant for identification purposes if you can (though it will probably scurry away too quickly). If you start to experience hives, swelling of the lips or tongue or difficulty breathing, get to an emergency room because these symptoms are signs of anaphylaxis.
If you suspect you have Asian needle ants on your property, you can snap a good photograph or collect an ant or two with tweezers to submit to your county agricultural agent for identification, Suiter says. There are no centralized entities mapping out the ants' spread, but Suiter says he hopes more public attention will spur more scientific research. Identification is particularly important for those who have had allergic reactions to bee and ant stings in the past. 'If people have a family member that suffers from anaphylaxis and knows it, and they carry around an Epipen,' he says, 'somebody like that needs to know what this ant looks like.'

Portuguese man o' wars — known for their sting — are actually 4 species. See them

Despite their vibrant blue color and delicate bodies, seeing a Portuguese man o' war along the coast sends beachgoers in the opposite direction. These jellyfish-like animals are known instead for their sting, prompting warnings from wildlife officials when they make their way onto beaches around the world. Now, researchers studying these unique creatures have found that Portuguese man o' wars — also known as bluebottles — may actually belong to at least four distinct species. A research team led by Yale University, in Connecticut, and the University of New South Wales and Griffith University, in Australia, analyzed the genetics of more than 150 bluebottles from around the world to better understand how the widespread species was related to one another, according to a study published June 19 in the peer-reviewed journal Current Biology. The team sequenced the genome of each bluebottle, then grouped them together in clusters based on their geographic range in the oceans, according to the study. What they found was distinct genetic differences between groups of man o' wars from different areas, despite some overlap between the populations, according to the study. 'We were shocked, because we assumed they were all the same species,' study author Kylie Pitt said in a June 20 news release from Griffith University. 'But the genetic data clearly show they're not only different, they're not even interbreeding despite overlapping ranges. The bluebottle is uniquely suited to long-distance travel, using its gas-filled float and muscular crest to catch the wind and sail the sea surface.' The study describes four species: Physalia physalis, Physalia utriculus, Physalia megalista and Physalia minuta. Researchers confirmed the species deviations by comparing their collected man o' wars to more than 4,000 images posted on the citizen-science website iNaturalist, according to the study. They compared differences in tentacle length, color and other physical characteristics to previous records of man o' wars found around the world, including in centuries-old publications that previously argued the species should be broken up, according to the study. Physalia minuta is described for the very first time as a new species, according to the study. The species is 'distinguished from other Physalia by its small size at maturity and colony arrangement with multiple principle tentacles,' researchers said, earning the species its name 'minuta,' meaning small. The well-known Portuguese man o' war — Physalia physalis — may look like a jellyfish, but it's actually a siphonophore, or a colony of animals that live together to create the complete structure, according to the National Oceanic and Atmospheric Administration. The specialized animals are called zooids and are genetically identical but each serve a different function for survival, such as floating, catching prey or reproduction, NOAA says. Man o' wars use a balloon-like float to move up and down in the water column, according to NOAA, and their tentacles can grow an average of 30 feet long, with some man o' wars reaching as long as 100 feet. 'There's this idea the open oceans all connected, and it's just one species of bluebottle and they're all globally connected because they drift with the wind and the current. But that's absolutely not the case,' Pitt said in the release. 'And what's really interesting in Eastern Australia is that we have multiple species that have evolved despite potentially co-existing.' Researchers said further studies will be needed to understand why, despite overlapping and being in the same environment, the man o' wars deviated, according to the release.

Rabies death alert has people worried: here's the UK risk, holiday spots to be aware of and symptoms

After a British woman, Yvonne Ford, 59, sadly died from rabies following a trip to Morocco where she was scratched by a dog, an alert has been shared by the UK Health Security Agency (UKHSA) to remind holiday goers to stay safe. UKHSA also sought to reassure those worried that rabies could become an issue here in the UK. In a new blog post responding to the news, UKHSA said while "the individual was diagnosed in Yorkshire and the Humber, there is no risk to the wider public in relation to this case". As a precautionary response, it added, "health workers and close contacts are being assessed and offered vaccination when necessary". But what actually is rabies and the risk of catching it while abroad? What symptoms should we be aware of? And what treatment options are there rabies? Given the tragic death of a woman in Yorkshire and the Humber in relation to rabies (a neurotropic virus) and the fact we're just emerging from a pandemic, it's understandable that people might be concerned. But, says superintendent pharmacist, Abbas Kanani MRPharmS, of Chemist Click, the risk of contracting rabies in the UK is extremely low. "The UKHSA report that there is no risk in animals and low risk in bats." Dr. Bruno Silvester Lope, lecturer in microbiology and epidemiology at Teesside University, adds that, "The UK is classified as rabies-free in terrestrial animals, meaning that the risk of rabies here is very low. The only reservoir of rabies-like viruses is in some species of bats, but human cases from bats are exceedingly rare." "There are a number of countries where the risk of rabies is particularly high. High-risk Asian countries include India, Thailand, Indonesia (Bali), Vietnam, Philippines and China," Dr Lopes notes. "Rabies is also a risk in Africa, and in particular countries such as Morocco, Egypt, Kenya, Tanzania and South Africa. People should also consider the risk of rabies when travelling to Brazil, Mexico, Peru, Turkey, Romania and Serbia. "These countries often have a large population of free-roaming dogs and less consistent access to post-exposure treatment." Always check the travel advice on the government website prior to visiting a new country and be mindful of interactions with animals. You can also look into getting a vaccination and speak with your GP about this. Elsewhere, the UK government has a list of other high risk rabies countries, some of which include: Canada and the USA are both listed as low risk but "foxes, skunks and racoons are high risk". "The main route for the transmission of rabies is by bites or scratches from infected mammals, particularly dogs, which make up over 99% of human cases worldwide," says Dr Lopes, who adds that cats and monkeys can also transmit rabies. "People can also contract rabies through other routes including licks on broken skin or mucous membranes such as the eyes or mouth, by dogs or very rarely, by bat bites." In order to keep safe, the number one piece of advice is to avoid contact with animals – in particular stray dogs, cats, and monkeys – no matter how cute, friendly or clean they may appear. Dr Lopes adds it's also best not to "feed or pet animals, even in tourist areas" and that it's "highly recommended to get a pre-exposure rabies vaccine if you are travelling to high-risk areas for long periods, visiting remote regions with limited medical access or working with animals". If you're bitten or scratched by a dog in a high risk country, it's always best to act quickly, says Dr Lopes, and get the wound cleaned before seeking medical help. "If bitten or scratched, immediately wash the wound with soap and water for at least 15 minutes and seek urgent medical attention for post-exposure prophylaxis (PEP) even if you are vaccinated," he says. Symptoms of rabies can vary from one person to another and may not appear immediately. In the case of Yvonne Ford, it is reported that it took several months for her symptoms (which included a headache which later led on to her being unable to walk, talk, sleep or swallow) to manifest. Ford passed away in June but visited Morocco back in February. Kanani says signs to be aware of include: "Symptoms usually take some time to appear, typically between 3 to 12 weeks of infection," he details. "Once these symptoms are present, it is likely to be fatal." Unfortunately, rabies cannot be treated once it reaches the central nervous system and symptoms begin, says Kanani explains. "People who have not had the rabies vaccine or have a compromised immune system may also be given a medicine called rabies immunoglobulin," he continues. "Ford's case is rare because rabies is preventable when the correct provisions are followed. However, the survival rate once rabies symptoms are present is practically non-existent." Dr Lopes adds, "Before rabies symptoms start, post-exposure prophylaxis PEP treatment is advised, as well as thorough wound cleaning for at least 15 minutes. In some cases, rabies immunoglobulin is required or rabies vaccination, which involves a course of four doses." Speaking about the very sad case of Yvonne Ford, Dr Lopes highlights "the recent death we have heard about in the news this week is a rare occurrence. Human rabies cases are very rare in the UK, and any death is typically due to infection acquired abroad. "This tends to happen when a person is bitten while travelling but does not seek prompt PEP, they do not realise the seriousness of the risk and there is limited access to care in remote areas."

Flying Bounce Houses - A Potentially Deadly Hazard For Kids

In this June 4, 2011, photo, participants in an Oceanside, N.Y., soccer tournament run from an ... More airborne inflatable "bounce house" after high winds sent it flying, scattering spectators and injuring 13 people, one critically. Saturday's inflatable mishap is the latest in a growing series of similar accidents, experts say. (AP Photo/Kim LoPiccolo) This week large inflatables were blown onto one of Atlanta's busiest roadways. I drive in that busy corridor frequently, and it is stunning that the city was spared a major incident. According to media reports, owners blamed the early installation phase for the lack of anchoring. This latest episode of 'flying inflatables' was relatively harmless, but other incidents have led to injuries or fatalities. Is it time to ban inflatable bounce houses? A boy plays in the bounce house at a pumpkin patch Tuesday, Oct. 9, 2018, in Seal Beach, Calif. (AP ... More Photo/Jae C. Hong) The answer to that question is probably 'no,' but experts are calling for changes. My colleague Dr. John Knox is a meteorology professor at the University of Georgia. He is one of the world's foremost experts on atmospheric sciences, including aviation meteorology. I suspect he did not have 'flying bounce houses' on his scholarly bingo card alongside his work on clear-air turbulence. However, Knox and his collaborators have become the foremost research group in the world documenting windy conditions and large inflatable structures. According to a UGA website, 'Over a decade ago, Dr. John Knox saw a joke on Facebook comparing the phenomenon of runaway bounce houses to the scientific study of dust particles in the atmosphere. Several years and hundreds of hours of intensive, intricate research later, Dr. Knox now admits that bounce houses are no joke.' In 2022, he and colleagues published a study in The Bulletin of the American Meteorological Society entitled, "Wind-Related Bounce House Incidents in Meteorological, Regulatory, and Outreach Contexts." At the time of publication, their analysis revealed 479 weather-related bounce house injuries and 28 deaths. The study also found that bounce houses are especially dangerous for children because they are often improperly anchored or parents are inattentive during play. Using data mining techniques and cartography, the team identified meteorological causes and connected them to incidents using geographical and social science methods. I asked Knox what needs to be done short of banning inflatables. He told me, 'What should happen? Federal regulations on their use in windy weather (or in all weather) would be a good start.' He pointed out, however, that their 2022 study found that many incidents occur where the nearest weather observations show winds under typical thresholds used in the states that do have regulations. During the warm season when bounce houses are popular, thunderstorms or windy conditions can happen suddenly. Knox went on to say, 'So even national regulations wouldn't be perfect. But the process of implementing federal regulations would raise public awareness of the dangers.' The rings represent outflow boundaries moving away from thunderstors. They can cause gusty ... More conditions suddenly that pose hazards for improperly secured bounce houses and inflatables. Knox continues to maintain what is likely the most robust database of bounce house incidents in the world. The website also includes safety recommendations and information about how different states regulate bounce house activity. Some interesting facts found on the website as of May 31st, 2025 include: The website also has accessible information on all known events spanning 2000 to 2025 and the associated weather types. What are some of the typical weather types connected to the events? They include cold fronts, dust devils, outflow boundaries, thunderstorms, Santa Ana winds, and sea breezes. Researchers are increasingly questioned about the value of scientific research. Knox and his team's work is an exemplar of how multidisciplinary research spanning meteorology, cartography, geography, and other social sciences disciplines can inform decisionmakers and save lives. Knox said, 'This research is a prototype for the kind of work geographers can do…. And then the website development exhibits the community outreach angle that is classic geography. So, this is what geography looks like--no siloes, everything together.' PHOENIX, ARIZONA - MARCH 30: A dust devil blows amongst the fans during the final round of the Ford ...
