Dramatic footage shows the moment a “biblical” swarm of flies descended on tourists as they tried to enjoy a day at the beach.
Dozens of people can be seen frantically swatting away the unwelcome insects on Blackpool seafront.
The seaside town was packed with visitors who were in attendance to enjoy the Blackpool Air Show.
However, the crowds were left to reach for hats and newspapers in an attempt to swat away a group of sandflies that one witness compared to one of the 10 Plagues of Egypt.
Sandfly bites cause small, itchy red bumps that can last for up to a week.
North Wales Live spoke to Lindsay King, who was visiting the popular resort with 18-year-old son Keiron King to watch the Blackpool Air Show for his birthday.
The bakery worker was waiting with her son for the Typhoon display to pass overhead when suddenly a swarm of sandflies descended on them.
The 51-year-old whipped her phone out to document the chaotic scenes as hundreds of day-trippers, some clutching deck chairs and picnics, frantically batted them away.
After a five-minute onslaught that the mum-of-three likened to one of the 10 Plagues of Egypt, the tiny blood suckers finally dispersed leaving everyone free to enjoy the show.
Lindsay, from Penrith in Cumbria, said: "It was hilarious, everybody was flapping around. It was biblical - like one of the 10 plagues.
"We were all waiting for the Typhoon display and then all of a sudden they just appeared. They came up over the bars and that was it - they hit the whole of the seafront at once and everyone was swatting away at them.
“It was really weird because one minute there was nothing there and the next it went crazy."
The sandflies, which Lindsay believes made an appearance when the tide went out, engulfed the crowd and left her worrying two of the mini monstrosities had gone up her nose.
Lindsay added: "They were really thick for about five minutes before they started to ease off a bit, but they were present all the time.
“I kept my mouth shut and had to blow my nostrils out, I was sure a couple had gone up there. Some people were too bothered about themselves while their kids got covered, and others were a bit OTT - like they were going to die with all these flies.
“I live near the border of Scotland and the midges up there are terrible, so I'm used to it."
Nonchalant Lindsay said on a future trip she may encounter one of the other nine plagues - quipping it'd be a “funny” place to experience it.
Lindsay said: "The next time we go it might be raining frogs. If something like the apocalypse did come to Blackpool it'd be a funny place for it."
