The UK Tick Surveillance Scheme (TSS) has published its latest findings, revealing the distribution, seasonal activity, and host associations of ticks across the country.
Between 2021 and 2024, the scheme received 3,182 tick records and detected 27 species. Ixodes ricinus, the main vector for Lyme disease and Tick-borne encephalitis, remains the most common tick in the UK.
The data also highlight occasional sightings of imported or non-native species, including Hyalomma marginatum on hosts with no history of foreign travel, though the risk of these species establishing locally is currently considered low.
The updated findings include species distribution maps and a new tick-bite incidence heat map for England and Wales, designed to support local public health interventions and awareness campaigns.
