Dozens of holidaymakers have been forced to pack up and leave their beach resorts because of the incredible noise which can be heard in this video from millions of grasshoppers that have invaded an entire coastline.

The ‘biblical’ event was recorded on beaches across the Romagna Riviera, on the southern coast of Italy.

Many tourists have reportedly fled after their stay was cut short by the pesky insects that swarmed the area between Bellaria Igea marina, San Mauro Mare and Cesenatico and because of the deafening row that went all day and night.

Several tourists filmed the sudden insect invasion that is reportedly getting worse day by day, leaving people unable to sleep; including both visitors as well as locals.

One piece of footage shows a tourist’s balcony and the whole outside of the next-door building covered in noisy grasshoppers.

Their loud chirping echoes through the entire neighbourhood, disturbing holidaymakers who reportedly decided it was time to go back home.

Another clip shows the insects taking over a beach and are seen all over the sand, the sunbeds and the umbrellas.

The beach seems largely empty after apparently being abandoned by horrified bathers.

The swarms of grasshoppers are believed to have come after strong gusts of the Garbino wind that have hit the area in recent days.

The Garbino – a southwestern wind from northern Africa that brings Saharan sand as it blows – is what most likely pushed the insects to move from the countryside to the coast, local experts said.

Beach lifeguards described the rare event as a “surprise that was not needed” and which they hope will run out as soon as possible.
