6 things you didn't know about ants, and how to kill them
Ants are marvelous creatures.
They're organized, brave, strategic – and you may have heard about how certain ants can lift up to 50 times their body weight.
But here's where ants aren't so marvelous: In your home.
Ants are among the most-common household pests in the world, parading through the kitchens, bathrooms and living spaces of city dwellers and suburbanites alike.
Of course, it's easy to dismiss their presence as a harmless nuisance, but when you find them in your loaf of bread, swimming at the bottom of your lemonade or worse, tangled in your hair, a line has to be drawn.
The good news? Ants are fairly easy to eradicate if you take the proper measures, and according to a 2015 Raid® consumer survey, the majority of Americans (82%) say that they aren't afraid to handle the problem themselves.
However, as with any pest, the more you know about them, the smarter you can be when it comes to getting rid of them.
Here's some “ant-astic” trivia that can aid you in your next bout with those crafty, six-legged interlopers.
1. Who run the world?
Ants build sophisticated societies with a distinct and entrenched social order: The queen (or several queens, in some cases) is the colony's sole way to reproduce and most important member; the queen is guarded by a group of soldier ants, and the remaining population works to feed the colony.
Funny enough, most of the colony is female — soldiers and workers included. Male ants exist purely to mate, and then die shortly after.
Tip: Succession can be complicated. So when ridding your house of ants, your number one priority should be taking out the queen. Without reproductive resources, the colony will fold in no time.
2. Follow the leader
When you see ants marching across your kitchen counter in a straight line, it isn't because they think it looks fancy. Rather, each ant in the line is following a pheromone trail left by the first ant to ever travel that route. Pheromones are chemical signals that ants lay down to attract and guide other ants to locations, such as food sources. The more ants that use the trail, the stronger the pheromone scent becomes.
Tip: Pheromone trails make it fairly easy to predict where ants will enter and exit your home. Monitor popular ant thoroughfares and strategically deploy baits along those routes.
3. Only the good die young
You can have an ant infestation for a year and potentially never see the same ant twice. Ant colonies are built for longevity, and can survive as long as the queen continues to populate the community, but some worker ants, on the other hand, only have a life span of up to a month.
Tip: When controlling ant invasions in your home, it's important to focus on eliminating the source — not just the current wave making its way across your dinner table. Use baits to get active ingredients into the colony and kill ants where they hide.
4. Introducing the New York City of ant colonies
Each species of ant has its own unique chemical profile — kind of like a fingerprint — that allows colony members to identify their own and weed out intruders. However, that chemical profile doesn’t always end with a single "hill." Some ants, like the Argentine ant, have found their way into every continent on Earth except Antarctica. Since this species has multiple queens, it can bud off to inhabit a new geographic location, allowing a single colony to stretch across continents to establish massive populations.
Tip: Even if your baits successfully eliminate one colony, there may be others on the way. Once you've gotten ants out of your home, it's important to protect its exterior, both by shoring-up cracks and entry points as well as spraying barrier sprays.
5. They aren't just after your food
It's easy to get caught up in visions of ants escorting a full pot roast out your back door, but like most living things, ants are just as interested in your water as they are your food. Ants will both drink water they come across and transport some back to the colony to nourish the queen.
Tip: When ant-proofing your home, don’t just secure your food items — make sure the surfaces in your home, sinks included, are kept dry.
6. Creating a defense system is the best way to help control & kill ants
A sophisticated problem requires a sophisticated solution. As discussed, simply killing the ants you see will only help you in the short term. The best defense you can mount includes a variety of resources, including baits and on-contact sprays.

Finding new species may call to mind images of scientists tracking mysterious footprints in the mud or cutting paths through the dense jungle.
But sometimes, a discovery is as easy as getting a frog to open its mouth and say, “Ah.”
Such is the case for Lenomyrmex hoelldobleri, a new tropical ant species found in the belly of a diablito, or little devil frog (Oophaga sylvatica), in Ecuador.
The diablito, a kind of bright orange poison frog, is known for its love of ants, says Christian Rabeling, a myrmecologist at the University of Rochester, New York. The new ant species is named after Bert Hölldobler, a German evolutionary biologist and ant expert, for his 80th birthday.
Because ant-eating frogs go hunting for bugs in tiny and hard-to-access places, scientists use them as a tool to go where they can’t go. By capturing a wild frog and flushing their stomachs, the amphibians vomit whatever is in their bellies—revealing potential treasures, like the new ant.
“Sometimes people think that our world is very well explored. Nothing could be farther from the truth,” says Rabeling, who led a new study on the ant, published September 19 by the journal ZooKeys.
Because the only known specimen of L. hoelldobleri is a dead one from a frog's stomach, scientists know almost nothing about it.
A glimpse through a high-powered stereomicroscope at that ill-fated ant, however, has offered a few clues. (See "Watch: Ants Use Giant Jaws to Catapult Out of Death Trap.")
“The shape of the mandibles reminds me of forceps,” says Rabeling. This may mean that the ant, which is less than a quarter of an inch long, uses its mouthparts to pry even smaller prey animals, such as termites, out of tight crevices. “But I am just speculating,” he admits.
If the scientists could find living L. hoelldobleri in the Ecuadoran rain forest, the team they could submit the little guys to a “cafeteria test," which means offering an animal multiple prey items to see what it prefers. (See "Surprising Ant 'Mixing Bowl' Found in Manhattan.")
“The difficulty is finding the ants!” says Rabeling.
The little devil frog, obviously, has figured out how to locate them—and for good reason.
Poison frogs get their namesake chemical defenses from alkaloids found in the ants and other critters they consume, says Jonathan Kolby, a National Geographic grantee and director of the Honduras Amphibian Rescue and Conservation Center.
"Physiologists regard ants as mini chemical factories," adds Rabeling. The insects likely use the chemicals as signals to communicate with other ants in their complex societies.
As for where the ants get their alkaloids, Kolby says some species may acquire it from the plants they eat. But what role, if any, L. hoelldobleri may play in the poison game is anyone’s guess.
Belly of the Beast
Because many amphibians are endangered—the International Union for Conservation of Nature lists O. sylvatica as near threatened—any research with wild frogs must be done carefully, and only by trained experts, Rabeling notes. (Read more about why amphibians are vanishing.)
To flush the stomach, scientists insert a soft tube into the amphibian’s mouth and gently fill it with water, prompting whatever the frog has eaten recently to flow out of its mouth and onto a tray. The frog can then be safely returned to its natural habitat.
This is not the first time a new species has been found inside another animal’s stomach, by the way. Kolby points to the example of Dunn’s earth snake (Geophis dunni), which was found in the stomach of a coral snake (Micrurus nigrocinctus) in Nicaragua in 1932.
Furthermore, it seems L. hoelldobleri had some company in the little devil frog’s stomach. The research project that first identified the new ant also found several other as-of-yet undescribed insects.
It seems the little devil’s frog's belly might be the gift that keeps on giving.
