A British city is facing a terrifying surge of “mutant” cockroaches that are taking over homes by nesting inside Wi-Fi routers, kettles and plug sockets. Pest control experts have sounded the alarm over a massive spike in infestations hitting Cardiff, with some teams being swamped by five to six emergency calls every single week.
Horrified residents have spoken out about the living nightmare, describing the creepy-crawlies as a source of extreme anxiety. Local resident Sumesh Geevarghese, 45, opened up about the harrowing ordeal of discovering his rented flat was crawling with the multiplying pests.
He first noticed the critters after a neighbour moved out, leaving belongings piled outside. Shortly after, the nightmare breached his own walls.
Speaking to BBC News, Geevarghese said: “I turned on the light and I could see a cockroach running, two or three were running.”
Desperate to wipe them out, he turned to standard supermarket bug sprays, but the chemical treatments failed to stop the resilient bugs.
He said: “They started coming from everywhere, from the WiFi router, under the kettle, the toaster and all the switchboards. We would cook and they would keep coming from the sockets, from under the microwave.”
After being told by the local council that a backlog meant they couldn’t respond, his letting agent stepped in to fund a private exterminator who finally cleared the flat after four visits.
Cardiff Council later clarified its stance, with a spokesperson saying: “Treatment of cockroaches is not a statutory service and the council does not currently provide this service for private residents.”
The species causing chaos is the notorious German cockroach, the most common of the five main pest cockroach species in the UK.
Despite their name, they actually originate from South East Asia and are entirely reliant on human environments to survive the British climate.
According to the British Pest Control Association (BPCA), the roaches carry dangerous pathogens known to cause food poisoning and severe bacterial infections in humans, including salmonella, staphylococcus and streptococcus.
Experts blame a combination of climate change and modern high-density housing for the population boom.
Dr George Beccaloni, a leading entomologist who worked at London’s Natural History Museum for more than two decades, explained that global warming is tipping the scales in the pests’ favour.
Dr Beccaloni said: “We know that lots of species are moving northwards and colonising Britain for the first time. The German cockroach needs warmth, food and water during the winter to survive.
“Now we’re having milder winters, populations of the cockroach in ducts and drains which would normally be killed by the cold, are probably able to survive the winter.”
Niall Gallagher of the BPCA pointed out that modern apartment blocks act as perfect incubators. Because blocks of flats share massive amounts of central heating and high-density living spaces, the bugs can easily spread from wall to wall.
He said: “They can do naturally well in usual room temperature, because they’ll seek out those additional sources of heat, such as your fridge motors and your, sort of humid areas.”
Pest professionals are urging Brits to ditch the DIY supermarket cans and call in the experts the second they spot a rogue antenna.
Gallagher added: “Sometimes people can get very embarrassed by pests because there is an inclination that maybe they’re dirty, which actually isn’t always the case. Sometimes you are just unfortunate.”
