Biggest flying ant day in recent memory is just days away, experts warn
Swarms will be made up of tens of millions of ants thanks to recent weather conditions
Flying ant day is just days away and experts say this year's swarms will be big - possibly the biggest in recent memory. Experts are warning of a major increase in flying ant swarms triggered by the recent alternating wet and hot weather, and say this year's Flying Ant Day - the annual nuptial flight when millions of winged ants swarm the skies - could be one of the biggest in recent memory.
According to bestantsuk: "Flying Ant Day in 2025 is predicted to occur earlier than usual, with peak activity anticipated around 22 and 25 of July." They said the first huge swarms could appear in the UK's large cities in June, thanks to the warming effect of big buildings and populations. They added: "Urban areas experience earlier flying ant emergencies due to the heat island effect. Cities maintain higher temperatures than surrounding rural areas, creating conditions that trigger premature ant colony activities, particularly in places like London."
Rentokil says this summer's conditions - especially high humidity - are ideal for swarming. Flying Ant Day actually takes place over a number of days - around 45 - and peaks on two or three days when the conditions are perfect and swarms are huge.
Paul Blackhurst, Technical Academy Head at Rentokil Pest Control, said: "Experts warn that this year could see larger-than-usual swarms of flying ants, as we approach Flying Ant Day, also known as the nuptial flight, and sometimes nicknamed 'flant day'.
"This natural event, when vast numbers of winged ants, known as alates, take to the skies at once in search of mates from other colonies, could be one of the most prolific for years. The alternating wet and warm weather we have been experiencing recently is creating the perfect conditions for larger-than-usual swarms, as humidity is important in keeping the ants' wings and bodies moist during flight and 'mating on the wing'.
"Despite the name, Flying Ant Day doesn't happen on a single fixed day each year. These swarming events can occur at different times across the country, depending on the weather, and in particular, temperature, humidity and wind.
"While you might see a few flying ants on most warm summer days, ideal weather conditions can trigger the appearance of tens of millions of them taking to the skies in massive swarms over several weeks across Britain. On radar, these dense clouds of insects can even resemble rain.
"Though it may seem like a summertime nuisance, this swarming strategy is believed to help more ants survive by overwhelming their predators including swifts and gulls.
"After mating mid-air, the male ants which are smaller will quickly fall to the ground and die. The newly fertilized female queens shed their wings and burrow into the soil to nest and start new colonies.
"While flying ants might disrupt your picnic, barbecue, or pub garden pint, they play a vital role in the ecosystem by aerating soil, recycling nutrients, and serving as a key food source for birds."
Ant prevention tips for your home from the pest experts at Rentokil:
Block entry points into your home by sealing cracks and crevices around doors, windows and pipework
Sweep up food debris from under kitchen appliances and units
Clear up any food or liquid spillages immediately.
Store your food in airtight containers wherever possible.
If you have a pet, clear away any food that isn't eaten straight away.
Make sure all rubbish bins have tightly sealed lids.
Keeping windows and doors shut is one of the most effective methods of preventing flying insects from entering your home
Installing a fly screen will prevent flying ants from entering your home, whilst still leaving windows and doors open
Use a strong detergent to remove any pheromone trails foraging ants have laid down to direct other ants to a food source.

Flying Ant Day: When is it? Have you seen any?
Picture the scene, it's a nice sunny afternoon and then suddenly an ANT FLIES AT YOUR FACE... Every summer there is a day when thousands of giant flying ants emerge from their nests roughly at the same time - known as Flying Ant the name, it can happen over a number of days and sees giant black ants with wings taking flight across the UK in warm weather. Why do ants fly? Flying Ant Day usually arrives during the summer months. Flying queens, which are larger, along with smaller male flying ants fly off to set-up new there is no such thing as a specific 'Ant Day', scientists have found that ants are good at short term weather prediction so chose a warm and calm day to is often in mid to late summer in the UK but varies across the country. Speaking to BBC Newsround, Cesar Wang, from Ant HQ, a flying Ant expert and ant-keeper who supplies ants for research said: "Rather than being a single day, it's more like a season, so it can actually start as early as June, all the way into September. "For example, I'm based in London and in London it's a very developed city, loads of buildings, so heat tends to accumulate a bit more, so ant nests which may be beneath paving slabs which absorb heat. "Their [the ants] development tends to increase and tends to be a little bit faster than usual, so these queen ants will hatch a bit earlier." Noting that flying ants may already be making an appearance this year, Cesar explained that "this year we've had quite a hot spring so we'll typically see flying ants emerging a little bit earlier." Are flying ants anything to worry about? While it might not be particularly pleasant to have several large ants flying at your face, Cesar says they're completely "harmless". Queen ants can be a bit scary if you've never seen them before, they're definitely much larger than the typical worker ants that you see in the park or garden."But here in the UK, there are 60-odd species and none of them have a lethal sting or bite and they won't be able to do anything to a human." Phew!

Why gulls sometimes seem drunk
Many a family seaside trip has been ruined by gulls dive-bombing tables and stealing chips. However, cowering Britons have often enjoyed a period of respite on so-called 'flying ant day', when the opportunistic scavengers appear 'drunk'. It was commonly thought the formic acid within the insects was intoxicating to the birds as they feasted on them. But scientists believe the gulls actually appear disorientated because they are 'so focused' on eating as much as they can, meaning they don't notice their surroundings and appear drunk. Dr Claire Asher, who has a PhD in Genetics, Ecology, and Evolution, told BBC Science Focus: 'Gulls feasting on swarms of flying ants have disrupted traffic and made headlines across the UK. 'Some claim that the gulls are drunk, but can eating ants really intoxicate these birds? 'Many ant species produce formic acid as a defence mechanism and this is toxic to birds. So, it's theoretically possible that gorging on ants might make gulls a little disoriented. 'However, the black garden ants that swarm across UK pavements in the summer only produce very small quantities of formic acid.' Gulls collide with cars Dr Asher said experts think it is the birds' focus on the short-lived supply of insect food that means they 'don't even notice' the cars they sometimes fly into. Flying ant day, a period that usually arrives around mid-July, as the queens emerge and travel to set up new colonies. But, swarms of the insects can appear any time between June and the start of September Organisations often warn drivers to stay vigilant on flying ant day due to 'drunk' gulls. The gulls are known to swarm onto grass verges and feast on the ants as they appear. Over the years, scores of dead seabirds have been found on roads in the aftermath of flying ant day, having collided with oncoming vehicles while gorging on the insects. In 2013, residents across Devon were shocked to find dozens of dead gulls in roads across the county. Last year, East Sussex Wildlife Rescue and Ambulance Service said it was 'inundated with road casualty gulls' and urged drivers to be cautious.
