The South West is know for its warm and often wet climate.

But scientists say the soggy August we have been suffering comes with another, somewhat alarming side effect.

The August damp weather so soon after a hot spring has created the ideal breeding conditions for fleas with penises two-and-a-half times the length of their body, it is being widely reported.

The 'super' males are said to have the largest genital, relative to size, of any bug on Earth, reports the Mirror.

Fed up with chilly, wet summer days, the insects are now desperate to hop indoors to feast on any flesh they can find.

Nigel Binns, of pest controllers 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."

The critters are often carried into homes on the fur of cats and dogs, especially if they've had contact with rodents, foxes or rabbits.

Mr Binns said scratching is often the first sign of a possible infestation.

He added: "Bite marks are usually around the ankles or legs, often leave small red spots, which are itchy.

"And, if you do have fleas in your home, you may even see them jumping on your carpet or furniture."

They thrive in the fur of pets but will soon hop on to sofas, bedding, carpets and rugs and breed at an alarming rate - the female can lay up to 50 eggs a day.

They hatch in a few days and can live for several months so the population soon explodes.

The RSPCA says that a flea can live from between 14 days up to one year, with the female laying up to 50 eggs a day, although they can survive without a host for many months.

The British Pest Control Association recommends regularly treating pets with flea treatment and removing infested bedding and regularly treating walls and floors to prevent the pests returning.
