Health bosses are calling on gardeners to be vigilant for mosquitoes that could be carrying two deadly diseases.

Warmer conditions as a result of climate change are being blamed for the spread of the bugs from the Far East to Europe.

It is now feared warmer conditions in Northern France and Southern England could see mosquitoes carrying dengue fever and West Nile Virus become commonplace in the region.

Experts from Public Health England have said “good garden husbandry” could help keep the disease-ridden critters at bay.

Jolyon Medlock, scientific programme leader with PHE’s medical entomology team, said: “We encourage good garden husbandry by reducing the number of container habitats around the garden.

“This includes turning upside down buckets, emptying paddling pools that aren’t being used, unblocking drains, and putting lids on water butts.”

It is understood the mosquitoes arrived in Europe in car tyres by laying their eggs in the rubber.

They can remain dormant in the tyres for up to 18 months before hatching.

As a result, PHE has also set up detection stations at ports and service stations across the South East.

These consist of black pots the size of beakers which are half filled with water and polystyrene.

As mosquitoes lay eggs above the water-line on the polystyrene, they are check by experts every two to three weeks.

West Nile Virus is spread by the species culex modestus which is believed to have been responsible for the disease in the south of France.

University of Liverpool experts have warned the disease-carrying creatures could become commonplace in the UK if climate change continues at its current rate.

Meanwhile, an outbreak of dengue fever in the UK would be unprecedented.

The infection can cause a sudden drop in blood pressure, bleeding and organ damage and potential death.

There is currently no commercially available vaccine on the market.

Mr Medlock added: “Given the continued spread of invasive mosquitoes in continental Europe, PHE continue to conduct surveillance near ports of entry and some motorways service stations, and provide an identification service for nuisance mosquitoes. So far no invasive mosquitoes have been detected in the UK.

“Mosquito levels tend to peak in July and August particularly in hot and wet summers. Some species will take advantage of the warm weather and water-filled habitats, like water butts or paddling pools to breed, particularly those without covers that collect leaves.”
