Billions of super-fleas are about to invade UK homes, experts have warned.
The recent hot and humid weather, with lots of thunderstorms, has created ideal breeding conditions for the insects.
The males, known as 'super-fleas', have penises 2.5 times the length of their body.
They are becoming increasingly resistant to insecticides and are causing havoc for humans, as well as pets.

Pet owners across the UK are being warned that a huge infestation of fleas could soon be heading their way. The influx is being caused by rising temperatures that provide the ideal breeding ground for fleas
Experts have warned that the changing climate across the UK is well suited to fleas.
Ged Cranny, store manager at Pets at Home in Weymouth, Dorset, said there could be a mass flea invasion this summer unless people take precautions.
Pet owners should check their home, as well as their dog or cat, for a flea infestation.
He said fleas can live within bedding as well as soft furnishings used by the whole family.
He advised all pet owners to wash pet bedding regularly at 60 degrees, clean furniture, hoover carpet and throw away the vacuum cleaner dustbag after each clean.
He also says people should check their pet's coat for 'flea dirt', which appears as brown or black spots.
Nigel Binns, a pest control expert from Basis Prompt, said: 'The activity and behaviour of fleas is often very much dependent on the climate.
'Mild temperatures during the winter means that fewer than usual will have been killed off and, as they thrive in a warm and humid environment, they're likely to be present in greater numbers than usual during the next few weeks.
'The population of fleas seems to have grown rapidly in recent years, but the risk of an infestation could be bigger than ever this summer.'
Fleas are known for their painful and itchy bites, and are usually carried into homes by cats and dogs, who can catch the pests from wildlife rodents, such as rats and foxes.

Once in the home, the creatures can easily hop around on furniture, carpets and rugs, where the females can lay up to 50 eggs every day.
And in warm and humid conditions, these eggs take just a few days to hatch.
