UK households have been warned to keep their windows closed until mid-August due to an impending surge of flying ants. According to insect expert Dr Nathaniel Green, the skies could be swarming with these insects across the country by mid-August.

Dr Green, who has over two decades of experience studying insectbehaviour, believes that conditions are "lining up perfectly" for a concentrated burst of the annual phenomenon known as Flying Ant Week.

He predicts that this year's activity will peak between August 13 and August 18, 2025, when warm temperatures, high humidity and calm air create the ideal conditions for millions of winged queens and males to take flight. It comes after an exciting heatwave forecast with maps revealing the exact date a 39C heat plume will scorch the UK.

"When the weather hits that sweet spot, it's like a signal for ants everywhere to take to the air at once," said Dr Green. "Afternoons will be the main time to watch out - or keep your windows firmly shut."

While flying ants aren't dangerous, they're not exactly welcome guests when they drift indoors - and dirty windows could be inviting them in, reports Leeds Live.

"Smears and dust on glass can reflect light in a way that draws insects closer," explained Dr Green. "Add in pollen or organic residue and you've basically got an insect buffet. Cleaning your windows before the swarms hit will make your home far less attractive to them."

Therefore, he's recommending that everyone cleans their windows immediately and keeps them shut during peak times in mid-August. The specialists at Quote My Wall, celebrated for their window sticker installations, have gathered extensive expertise on window-cleaning methods, as spotless glass is essential before any sticker fitting.

They suggest: "Choose the right cleaner – A mix of equal parts white vinegar and water, or a quality glass cleaner, will break down grime and leave nothing for insects to feast on. Swap paper towels for microfibre cloths – They trap dust better, stop streaks, and give you a truly clean surface."

"Pick your moment – Clean on an overcast day. Direct sun dries the solution too fast and leaves marks. The flying phase only lasts a few days," Dr. Green said. "Males die soon after mating, and fertilised queens land to start new colonies."
