WE could soon see a surge in flying ants, including here in North Wales, experts have warned.

Best Ants UK is once again warning that 'Flying Ant Day' could be upon us very soon.

They have warned that the 'fascinating natural phenomenon', which involves the black garden ant (Lasius niger), will 'likely come earlier and be more intense than before'.

The experts added: "Our data from the last 24 years shows 90% of nuptial flights happened in July, but as experts in myrmecology (the study of ants) now predict, the peak for 2026 will hit between July 20 and 25."

While it's known as Flying Ant Day, it typically extends over multiple days, and has even been recorded to continue for several weeks in some years.

Best Ants UK added: "The UK's flying ant season stands out as a captivating event in the field of entomology. These tiny flying insects show up on Met Office radar systems because they're about the size of raindrops. Weather radar has even picked up swarms stretching more than a mile wide."

Ants tend to take flight sooner in built-up areas than countryside regions, likely because temperatures are typically warmer in urban settings.

Swarms often first appear in southern regions such as Cornwall and Kent, Best Ants UK added, before spreading north across the UK.
