While ants can be pests in Auckland, they are still amazing little creatures! ACES pest control is sometimes surprised at how resourceful ants are. This article shows another way that ants are amazing!
Ants don't tend to get in traffic jams. They might butt heads (or antennae) momentarily as they go about their industrious business, but ants somehow have mastered the art of keeping things moving. They're geniuses of flow.
Another striking thing about ants is that some of them just sit around doing nothing. This has also been noticed in other social insects, such as bees. When ants build a nest, some of them just sit around, inert, lazy, seemingly useless.
Now a study out of Georgia Tech, published Thursday in the journal Science, combines these observations to deliver a lesson that could have implications for such things as how the robots of the future might be used for disaster relief. The researchers found that ants are more successful when they are selectively industrious. They use idleness to their advantage. Quitting has its virtues.
The researchers studied groups of 30 color-coded fire ants digging tunnels in glass-walled containers in a laboratory. About 30 percent of the ants did 70 percent of the work. Some ants did very little or nothing. When the researchers removed the most hard-working ants, some of the previously less-active ants stepped up their game and began working harder. It appears that industriousness is not an individual attribute but a defined role. It's like a job title: heavy lifter.
When excavating a tunnel during the frenzy of nest-building, the tunnel face the deep end of the tunnel can get crowded. That can cause traffic jams. What the researchers noted is that some ants turn around and leave the tunnel without doing any work. These reversals limit the potential for clogging up the works.
The team created computer models with simulated ants and found that this system of selective idleness enables the ants to dig deep faster. Their method reduces the chances of clogs. In effect, the ants have solved the eternal problem of too many cooks in the kitchen.
“What the ants have discovered is pretty close to the best way to do it. You need the idleness distribution and the appropriate amount of giving up, said Daniel Goldman, a Georgia Tech physicist who runs the lab and is the senior author of the new study.
“It’s a nice example of where doing less gives you more. And perhaps the most, said Ofer Feinerman, a physicist who studies ants at the Weizmann Institute of Science in Israel and who was not involved in the new research. It seems the ants do the best that they could have done.
The Georgia Tech team built robots to try to simulate the ant behavior and couldn't quite match it, apparently because a robot is clunkier than a segmented, limber ant. But the robot work confirmed the basic idea that simple rules, such as knowing when to quit and let other individuals do the work, can benefit the overall project.
This kind of investigation could lead to improved designs for robot swarms. For example, multiple autonomous robots may need to enter buildings destroyed by earthquakes to look for survivors. Such efforts could benefit from simple strategies that involve labor inequality, the new paper states.
“If you wanted to have a system of diggers dig in a confined area, you don’t want to throw them all at the same tunnel. You want to have them selectively participate and not participate based on these physics-inspired rules, said Nick Gravish, a University of California at San Diego professor who studies ant biomechanics. Gravish earned his doctorate under Goldman at Georgia Tech but was not involved in the current study.
The principle of selective idleness could aid human teams working collectively on a document or a piece of computer code, said Simon Garnier, a professor at the New Jersey Institute of Technology who studies collective behaviors in everything from slime mold to fish to mammals. "As long as all the agents in the system have a common collective goal, this principle might help them achieve it faster by reducing conflicts in accessing a common resource," Garnier said.
Fire ants are an invasive species common in the Deep South. They first arrived in the United States less than a century ago from the wetlands of South America.
They often live in low-lying, flood-prone areas. A fire ant colony functions like a superorganism. During a flood, the entire colony forms a raft, with the queen protected in the middle. This happened notably last year when Hurricane Harvey flooded the Southeast Texas coast.
The colony floats on the surface of the floodwater. When the ant-raft finally washes up somewhere, the ants build a nest rapidly. The workers (all female) can't leave the queen exposed.
No matter what kind of soil the ants dig in, they make their tunnels roughly the diameter of the length of an ant. That means their legs and antennae are always within reach of the tunnel wall, which assists the ants during moments of slippage. They can use their antennae as if they were auxiliary limbs.
Feinerman said researchers have noted that ants are sensitive to success and failure. When an individual ant tries to do something, such as obtain food or dig a tunnel, and is successful, she keeps doing it with extraordinary vigor and endurance. But when she fails, such as getting stymied while trying to enter a tunnel, she will quit and become inert. He said the new research suggests that relatively simple rules govern this behavior.
“There’s a positive feedback between how successful an ant is and her tendency to repeat the task, he said.
Gravish, who builds robots inspired by insects, said of ants: They’re far more complicated than robots. I wish we could get even close to the complexity of ants.

Man lets a bullet ant sting him on purpose and you’ll absolutely believe what happens next
ACES pest control have had their fare share of wasps stings, but that is rated 1 on a scale of 30. The bullet ant is rated the worse sting in the world for pain- that's number 30. So we can tell you this guy is 100% BONKERS
"About two months ago, we witnessed outdoor adventurer Coyote Peterson let a wasp known as a tarantula hawk sting him on his arm. Boasting the second most painful sting in the insect world, the tarantula hawk quickly had Petereson writhing on the ground in pain. And of course, it was all captured in a harrowing and altogether fascinating video.
Earlier this week, Coyote Peterson was at it again during an episode of Breaking Trail, this time taking things a bit further and letting himself get stung by a bullet ant, the insect widely believed to have the most painful sting in the world. The bullet ant typically inhabits rainforests in Central America, so odds are you don’t have to worry about coming into contact with one them. But if you’re sporting a name like Coyote Peterson, well, you pretty much have no choice but to seek out the bullet ant yourself.
According to the Schmidt Pain Index, the bullet ant, if I may repurpose some old Wu-Tang Clan lyrics, ain’t nothing to mess with. The resulting pain from a bullet ant sting is said to be extremely intense and feels like you’re “walking over flaming charcoal with a 3-inch nail in your heel.” Interestingly enough, the reason why this fearsome insect is called a ‘bullet ant’ is because its sting is said to be as painful as a gunshot.
And for reasons that defy explanation, our fearless hero Coyote Peterson thought it might be a fun idea to get stung by one of these creatures on purpose. Naturally, it was all recorded on video for our collective enjoyment/horror."

"ACES pest control sees how smart insects are, in particular ants on a daily basis.
In fact Universities once pondered why an ant would slave and give its life for the colony or nest when they get nothing in return. The answer was to be found in looking at the nest as a single organism. This maybe why ants seem so smart, because its the collective thinking of the nest we are seeing.....here an article on just how smart ants are. "
"The brain of an ant is the size of a pinhead"
Ants are even more impressive at navigating than we thought.
Scientists say they can follow a compass route, regardless of the direction in which they are facing.
It is the equivalent of trying to find your way home while walking backwards or even spinning round and round.
Experiments suggest ants keep to the right path by plotting the Sun's position in the sky which they combine with visual information about their surroundings.
"Our main finding is that ants can decouple their direction of travel from their body orientation," said Dr Antoine Wystrach of the University of Edinburgh and CNRS in Paris.
"They can maintain a direction of travel, let's say north, independently of their current body orientation."
Ants stand out in the insect world because of their navigational ability.
Living in large colonies, they need to forage for food and carry it back to their nest.
This often requires dragging food long distances backwards.
Scientists say that despite its small size, the brain of ants is remarkably sophisticated.
"They construct a more sophisticated representation of direction than we envisaged and they can incorporate or integrate information from different modalities into that representation," Dr Wystrach added.
"It is the transfer of information aspect which implies synergy between different brain areas."
UK and French researchers came up with their findings by studying desert ants.
Experiments suggest the ants kept to the right path by following celestial cues. They set off in the wrong direction if a mirror was used to obscure the Sun.
If they were travelling backwards, dragging food back to their nest, they combined this information with visual cues. They stopped, dropped the food and took a quick peek at their route.
Scientists say the work could have applications in designing computer algorithms to guide robots.
Prof Barbara Webb of the University of Edinburgh's School of Informatics said the ant can navigate much like a self-driving car.
"Ants have a relatively tiny brain, less than the size of a pinhead," she said.
"Yet they can navigate successfully under many difficult conditions, including going backwards.
"Understanding their behaviour gives us new insights into brain function and has inspired us to build robot systems that mimic their functions."
She said they have been able to model the neural circuits in the ant's brain.
The hope is to develop robots that can navigate in natural areas such as forests.
The research is published in the journal Current Biology.

How do I get rid of ants?
Although ants generally don’t cause harm to people — they don’t carry disease, like some other pests — an infestation can be a major nuisance.
“Ants can be extremely persistent creatures, seemingly coming from nowhere and can be difficult to entirely get rid of,” says Kelly Garvin of Greenix Pest Control in Dublin, Ohio.
Fortunately, DIY and professional pest removal options are available.
REASONS FOR ANT INFESTATION
Ants typically invade your home for one reason: food. Most feed on sugary or greasy items.
Sugar ants — also called odorous house ants — are one of the most common ant invaders and among the first pests to show up in the spring. They’re about one-eighth of an inch or smaller and are attracted to food sources.
The common pavement ant, which is brown to black and about 1/10th of an inch long, will set up colonies near driveways or patios and then send out scouts to search for food in your home. They eat meat, grease, seeds, dead or live insects, and can sting and bite if disturbed.
Argentine Ants — about 4 to 4.5 mm long ONE size. Usually come into your house for food. Loves protein and fat, often found in your dishwasher or pantry.
Coastal Brown Ants- two sizes. Dark brown, loves protein often found in dishwasher. Two sizes one has a BIG head.
Knowing what type of ant you’re dealing with can help you prevent or combat an infestation.
KEEPING ANTS OUT
The first step to prevent an ant infestation: clean house. If you see scout ants in your home, kill them immediately. Make sure you don’t leave any food out and keep all kitchen surfaces clean.
If you continue to see ants, make sure you’ve closed off possible entry points, including sealing small cracks in your walls or under windows. Start by caulking potential entry points, such as window casings.
Next, you can lay down barriers like salt or talc under doors to turn ants away, or apply scents such as vinegar, peppermint oil or cinnamon. Bear in mind, however, that anything you put down will also be of interest to pets and children, so be careful what you use.
DIY METHODS FOR ANT REMOVAL
If ant explorers have morphed into a full-on colony, then you need a plan.
Start with soap and water. This will not only kill chemical trails, but any ants it touches. Add citrus to the water to increase its effectiveness.
You can also purchase pest sprays and baited ant traps from local grocery and hardware stores. These use a mixture of sugars and ant poison, such as boric acid to attract, trap and kill ants. Proceed with caution when using poison.
Bear in mind, too, that these traps won’t work on protein-feeders like Coastal Brown or Argentine Ants, since the sweetness won’t interest them.
In addition to trapping ants inside, you can also spray around the exterior of the home where the house meets the pavement or ground to prevent more ants from infiltrating, says David Anderson of Eastside Exterminators in Woodinville, Wash.
Garvin recommends spraying problem areas with a mixture of Windex, vinegar and water. She says spreading Diatomaceous Earth in carpeted areas around the bathroom is a safe and natural way to kill ants because it’s a food source.
“The Windex or vinegar is really a quick fix and not really that effective, but it will remove the immediate ants and wipe away their pheromone scent they use to follow trails,” Garvin says.
Dan Miles, owner of Total Exterminating in Indianapolis, suggests spraying all cracks around the baseboards and the base of the toilet if the infestation is in the bathroom.
HIRE A PEST CONTROL PROFESSIONAL
Large-scale infestations require assistance from a pest control professional.
Pros address ant problems by locating the colony itself; typically this starts by laying bait traps, which contain poisoned food taken back to the nest. Once found, exterminators can use a variety of techniques including chemical sprays to totally eliminate the ants in your home.
