Climate change, which saw record temperatures across Mallorca last summer, could be causing an alarming rise in the number of cockroach infestations in Spain - as well as alterations to their genetic makeup.
So far this year, Spanish authorities have reported a significant rise in infestations - up by 33 per cent compared to the rate in 2023, according to Euronews.
Experts say record hot temperatures are to blame for these ‘mutant’ cockroaches. Increased heat means the pests’ metabolic cycles accelerate - and it’s particularly evident in the Germanic cockroach. That’s a worry as that variety is prevalent in homes and food-related businesses.
Hotter-than-average temperatures also mean that the breeding season of the creatures is getting longer and their genetic resistance to conventional insecticides has been enhanced.
All of these factors are linked to a broader and more serious public health issue, with more frequent sightings being reported in both residential and commercial establishments.

Lisa JuliaAnd extra Mosquito controls. After 30 years of visiting Alcudia, It's time for a change. The Bellevue area needs a good cash injection.
It may also have something to do with councils failing to spray the drains in towns over the last couple of years. There used to be a full program of pest control- which aimed to prevent the problem, becoming a problem. The last two years in Alcúdia, there was NO proper drain (where they’re breeding) control. Neglect this simple task at your peril!!! PS as a footnote - Alcúdia has approaching 100 million euros in their reserves. So they can afford pest control.
