Long-distance haulage firms are being forced off the road to allow for cabs to be fumigated – adding to the woes of truck drivers already hit by Operation Stack.

They have already been badly affected by the migrant crisis in Calais this summer with thousands of people trying to jump the outer security fence each night to come to England.

Now drivers, who spend weeks overseas in their trucks, are being driven mad by these not-so-little insects.

Experts say the 'uber-fleas' can't be killed by high street repellents.

They bite exposed skin and suck the blood of sleeping drivers who are required by law to rest after a specified numbers of hours on the road.

But sniffer dogs can detect the bugs in lorry cabs in 150 seconds.

Operations director Peter Davis, of pest control company Merlin Environmental Solutions, said: "Over the past few years the levels have steadily increased.

"We are now getting daily requests from haulage companies to assist.

"This pattern of activity is set to continue for the foreseeable future."

He called the impact of the bugs on a lorry "incredibly destructive".

Pest boffins say a "perfect storm" of a mild winter followed by the right mix of heat and rain this summer has created ideal breeding conditions.

The male invaders come equipped with a huge penis – two–and–a–half times the length of their body.

Their apparatus is believed to be the largest of any other insect around.

The big fella fleas are just itching to use their huge willies with their harems of females.

The news of this latest insect invasion comes as thousands of bees were pictured hitching a ride on a passenger plane at a Moscow airport earlier this summer.

They swarmed an Airbus-319 as it was about to start taxing ahead of taking off from Vnukovo Airport.
