The wildlife groups have released a list of eight species set to wreak havoc, including Japanese Knotweed, Giant Hogweed, and Red Imported Fire Ants.

The last 18 months have been the wettest in England since records began back in 1836.

Beyond making us all miserable, this wet weather could also spark a surge in invasive species that thrive in wet conditions, according to the experts.

'Invasive species are already one of the biggest threats to the UK environment, from smothering waterways to outcompeting native species,' Mr Benwell said.

'They also cause billions of pounds in damage a year to homes and businesses, and even pose risks to human health.'

The team highlights six invasive species already established in UK, which spread and thrive in excessively wet conditions.
