Flying Ant Day: Unveiling the Enigmatic Annual Event

Flying Ant Day is an intriguing and awe-inspiring natural phenomenon that occurs annually, with numerous people across the United Kingdom finding themselves in the midst of swarms of winged insects, known as flying ants. In this article, we delve into the heart of this enigma, aiming to shed light on its fundamental aspects and respond to frequently asked questions around the topic.

What are Flying Ants?

Flying ants are not a distinct species of ant, but rather a reproductive stage in the life cycle of many ant species. Commonly referred to as alates, these winged ants are males and future queens – females preparing for their nuptial flight. Their main aim is to mate, establish new colonies, and ensure the survival and expansion of their species.

While there are many species of ants in the UK, such as the black garden ant (Lasius niger) and the red ant (Myrmica rubra), it is the flying variety of these ants that gain the most attention. Notable for their larger size and the presence of wings, flying ants are typically seen during the warmest periods of the year, when conditions are optimal for their reproductive flights.

What is Flying Ant Day?

“Flying Ant Day” refers to the period, usually in the summer months, when ants emerge from their colonies to mate and start new colonies. The event doesn’t necessarily occur on a single day, but rather it stretches over a few days or weeks, depending on the weather conditions and the specific species.

The nuptial flight begins with female ants, or queens, releasing pheromones to attract male ants. After mating mid-air, the males die, and the now fertilised queens land to find suitable locations to begin their new colonies. The queens shed their wings, which often leads to the misconception that the flying ants have “disappeared”.

When is Flying Ant Day?

The exact timing of Flying Ant Day varies, but it usually takes place between June and September, during warm, humid weather, often after rainfall. This time window ensures the best possible conditions for the ants to mate and start new colonies. However, the timing can fluctuate based on weather patterns and geographical location.

Where do Flying Ants Come From?

Flying ants come from established ant colonies. Ants are eusocial insects, meaning they live in highly organised colonies where each member has a specific role. In such a colony, the queen is the only breeding female, and she produces all the offspring. During the nuptial flight period, the queen produces winged ants, both males, and future queens, who leave the nest to mate and establish new colonies.

Flying Ant Day in the UK 

In the UK, Flying Ant Day has become a notable annual event, capturing the attention of the public and scientists alike. The phenomenon is so widespread that it can even be seen from space, as satellites have captured images of the swarms appearing as rain on weather radars.

While the event might seem alarming due to the number of ants, it’s worth noting that they pose little threat to humans. They are not aggressive and do not typically bite. In fact, the event is a boon for many bird species, which feast on the plentiful ants.

Flying Ant Day FAQs

Are flying ants dangerous?

Despite their somewhat intimidating appearance, flying ants are generally not dangerous to humans. They are more focused on reproduction than causing harm. However, like any insect, they could bite or sting if threatened.

How long does Flying Ants Day last?

Flying Ant Day isn’t restricted to a single day. It typically spans several days or weeks, depending on weather conditions and the specific species of ant.

Why do flying ants appear on the same day?

This synchronised emergence is largely driven by weather conditions. Ants prefer warm, humid, and windless conditions for their nuptial flights. This increases the likelihood of multiple colonies participating simultaneously, creating the ‘Flying Ant Day’ phenomenon.

What happens to flying ants after they mate?

Once the male flying ants mate, they die shortly afterwards. The fertilised queens, on the other hand, land and shed their wings to start new colonies underground, marking the next stage of their life cycle.

Why are seagulls attracted to flying ants?

Seagulls and other bird species see flying ants day as a feeding bonanza. The ants contain formic acid, which can intoxicate the birds, sometimes leading to unusual behaviour.

Can flying ants infest houses?

While it’s possible for flying ants to enter houses, they’re usually more interested in outdoor areas where they can start new colonies. However, if you notice a large number of flying ants in your home, it might indicate an existing ant colony in your building.

What’s the ecological significance of Flying Ant Day?

Flying Ant Day plays a crucial role in the ant life cycle, allowing for genetic diversity and the propagation of ant species. Furthermore, it provides a food source for a variety of predators and contributes to nutrient cycling in the ecosystem.

We thought we had bedbugs but could find no evidence apart from what we thought were bites. I called Bon Accord and Gabriel was there within a couple of hours. He told us we had carpet beetle. Finding the evidence and showing us photos of the skin reaction which was exactly what we had. He advised and returned at a time to suit us to spray which was done thoroughly and efficiently. No sign of the little critters returning. Thank you Gabriel.

Gabriel was absolutely wonderful, a real life saver when I found a mouse by my bed at 10pm. He came in less than an hour and was able to catch the mouse and put my mind at rest so I could go to sleep! Highly recommend, fab service and lovely people.

Gabriel turned up with an hours notice one evening and immediately identified the issued. He works efficiently and professionally throughout with timely follow-ups to ensure the problem was resolved. Once completed he was kind enough to continue to check in to see that the issue had gone. Having had Rentokil previously that spent two years doing very little this was a complete breathe of fresh air and solved the problem in less than two weeks. We are grateful and would highly recommend his services.

We were lucky to have found Bon Accord, they responded very fast to our request and Gabriel was very helpful and informative. He made several visits and did his absolute best until the mice problem we had was gone. Highly recommended.
