Do Flying Ants Bite? Facts About Ant Swarms, Stings, and Bites

Do Flying Ants Bite?

Flying ants, also known as alates, are winged ants that emerge from the nests of established ant colonies to mate and start new colonies. They are a common sight on warm days, swarming around in large numbers. But do these winged ants actually bite or sting?

The short answer is: flying ants do not bite or sting. While ants can inflict painful stings and bites when provoked, flying ants are generally harmless to humans.

Flying ants do not have stingers or mandibles capable of piercing human skin. Their sole purpose during the flight stage is reproduction. They are focused on mating, not defending their nest or colony. Additionally, flying ants do not carry food back to the nest, so they have no need to bite or sting to capture prey.

However, some key facts about flying ant mouths and potential reactions:

• Flying ants have mandibles (jaw-like structures) at the front of their mouths, used to carry items like pupae. But these mandibles cannot break human skin.
• If a flying ant does happen to get trapped against bare skin, it may try to bite. But its small mandibles will likely not manage to pinch or puncture.
• On the rare occasion a pinch occurs, it may feel like a mild pinch or cause a small welt. This is from the ant's legs or body, not its mandibles.
• Some people may experience minor irritation, redness or itching from ant secretions or the abrasion of legs against skin. But flying ants do not inject venom.

So in most cases, flying ants are completely harmless to humans. But what about other biting and stinging ants one may encounter around the home and yard?

Ants That Can Sting and Bite

While flying ants themselves do not sting or bite, some ant species that produce flying ants can sting and bite during their wingless stages. These include:

Fire Ants

Fire ants are known for their painful stings, which inject venom. Their stings produce a burning sensation and small, fluid-filled blisters that become itchy and swollen. Though very uncomfortable, they are not typically dangerous unless the person is allergic.

Carpenter Ants

Carpenter ants have large mandibles they use to bite. The bites are painful and can break the skin, but don't often cause major issues beyond some mild swelling, redness and itching.

Harvester Ants

Harvester ants can inflict irritating stings, especially red harvester ants. The stings produce intense pain and itching/swelling in the area.

Bulldog Ants

Bulldog ants, named for their shape, have large mandibles and can produce a painful bite. They are found mainly in Australia but some species occur in other regions like Hawaii.

So while winged carpenter ants, fire ants and other ant species do not bite or sting while flying, their grounded colony members still pose a stinging/biting risk if provoked. It is wise to avoid disturbing ant nests and mounds.

Signs of Ant Stings and Bites

How can you tell if an ant has stung or bitten? Here are the signs and symptoms:

• Stings - Sharp, sudden pain at the site. Burning/itching sensation. A small, red welt that forms a white pustule on top.
• Bites - Quick, sharp pain that may feel like a pinch. One or more small, red, swollen spots that may leak fluid and become itchy.
• Mild allergic reaction - Large swelling/redness beyond the bite site, itching of the skin or eyes, runny nose, sneezing.
• Severe reaction - Difficulty breathing, dizziness, stomach cramps, chest tightness.

A severe reaction requires emergency care, as it could lead to anaphylaxis. But in most cases, ant stings and bites heal on their own.

Treating Ant Bites and Stings

For mild discomfort from an ant bite/sting:

• Wash the area with soap and water to remove any remaining venom/irritants.
• Apply a cold compress to reduce swelling and soothe pain.
• Take an antihistamine containing diphenhydramine to relieve itching.
• Apply hydrocortisone cream to lessen inflammation.
• Monitor for signs of infection like pus, increasing pain/swelling/redness.

See a doctor if symptoms do not improve within a few days or seem to be getting worse instead of better. Signs of infection require antibiotic treatment.

When to Seek Emergency Care

Seek immediate medical care if:

• Breathing difficulties, dizziness, nausea/vomiting occur.
• Swelling spreads rapidly beyond the bite site.
• There are multiple stings (more venom injected).

These require urgent care to prevent a severe reaction, anaphylaxis, injury to tissues, and other complications.

Preventing Ant Bites and Stings

Use the following tips to help prevent ant stings and bites:

• Watch for ants entering the home and seal cracks/crevices.
• Store food in sealed containers and eliminate exposed food debris.
• Avoid disturbing or stepping on ant mounds.
• Wear shoes outdoors when ants are active.
• Apply insect repellent if spending time near ant nests.
• Treat ant mounds with boiling water or ant pesticide.
• Trim vegetation touching the home's exterior.

Taking preventive measures can reduce the chances of inadvertently provoking stinging/biting ants. But rest assured that flying ants themselves pose no stinging or biting risk.

Are Flying Ants Dangerous?

While flying ants can certainly be a nuisance when they appear in swarms, they do not present any danger through stinging or biting. Some key facts about the risks:

• Their mandibles cannot pierce human skin, so they cannot bite or sting.
• They do not spread diseases or contaminate food as they do not forage or visit waste areas.
• They do not cause structural damage to homes.
• While wings and bodies may pile up where swarms congregate, they do not cause health hazards.
• They are not poisonous or venomous and cannot transmit dangerous substances.

However, their large numbers can cause some temporary concerns:

• Swarms near roads can obstruct visibility for drivers.
• Masses of flying ants can be a nuisance if they get indoors.
• Some people may experience minor skin/respiratory irritation being around flying ants.

So while they should not cause injury or illness, take sensible precautions like keeping windows and doors closed and watching for swarms near roadways.

Why Do Flying Ants Swarm?

Flying ant swarms occur when mature ant colonies produce winged ants known as reproductives or alates. This happens for a few reasons:

• To prevent overcrowding and competition within a mature colony.
• To mate with ants from other colonies to increase genetic diversity.
• To spread and establish new satellite colonies.

Swarming allows the ants to disperse over a wide area to find new mates and suitable locations for building nests and raising brood. This is vital for their reproductive cycle and continued propagation as a species.

When Do Flying Ants Appear?

Flying ants emerge in spring and summer, often after rainfall, when conditions are warm (60-90°F), humid, and wind speeds are low. Times vary by species and location, but commonly:

• Late April to mid-May
• Mid-July to late August

Swarms typically take place during the day and mating flights last several hours until males die and queens land to start new colonies.

Fun Facts About Flying Ants

• Ants evolved wings around 100 million years ago.
• Not all ants develop wings - only reproductive male drones and virgin queen ants grow wings.
• A flying ant colony can produce thousands of flying ants during swarming.
• Flying ants are poor fliers and often just glide clumsily before crash landing.
• Queens mate mid-air with several males, storing up to 300 million sperm.
• Most ants you encounter outdoors do not come from the nests of flying ants.
• Flying ants send chemical signals to indicate swarming time.
• Ants use visual cues like sunlight patterns to initiate mating flights.

Flying Ants vs. Termites

Because of their winged swarmers, flying ants are often confused with termites. But there are some key differences:

• Ants - Narrow waist, elbowed antennae, hind wings smaller than forewings.
• Termites - Broad waist, straight antennae, forewings and hind wings equal size.

Other differences:

• Flying ants only swarm for mating purposes. Termites swarm to disperse and find new food sources.
• Ants bite and sting, termites do not.
• Ants live in colonies with different types of roles. Termites have no division of labor.
• Ants eat liquids, sweets, proteins. Termites eat only wood/cellulose.

In Conclusion

While flying ants can certainly cause nuisance, they do not present any biting or stinging hazard to humans. They emerge in spring and summer to mate and start new colonies, not to prey on humans or animals. Aside from minor irritation from close contact, they are harmless. However, it is still smart to be cautious around anthills and reported swarms near roadways due to reduced visibility.

With some basic prevention and avoidance, flying ants do not need to become more than a passing nuisance. And rest assured they cannot break skin or inject toxins when swarming outside the nest. So although they may give you a minor fright when they appear en masse, flying ants will not bite!
