A survey by the Big Tick Project has named Norfolk and Suffolk among the counties most at risk from ticks.

Almost a third of dogs in the UK were found to be carrying ticks, which carry a range of diseases including Lyme disease.

Professor Richard Wall, project leader, said: 'The work that we have carried out shows that ticks are extremely widely dispersed. The records that we have got appear to show that we have had an increase in tick numbers right across the country.'

Log grass, woodland areas, but also urban areas are known to be hot spots for ticks.
