Tick threat grows amid rising Lyme disease cases

A growing tick population in the UK countryside is increasing the risk of Lyme disease, warns the Scottish Land & Estates (SLE).

The warning comes following a rise of one-third in reported Lyme disease cases in the UK during summer 2023 compared to the previous year.

Ticks are tiny, spider-like parasites found in grassland, woodland, and moors, and can transmit a range of infections, including Lyme disease.

These parasites feed on the blood of animals and people, especially between April and July when ticks are most active.

Most are harmless, but some carry the Borrelia bacteria responsible for Lyme disease.

“Ticks can be as small as a poppy seed when they attach to your skin,” said Eleanor Kay, SLE senior policy adviser on agriculture and climate change.

“Remove the tick as soon as possible and check your children and pets for any ticks.”

The increase in tick numbers has been linked to climate change, which has accelerated vegetation growth, ideal conditions for tick breeding.

Bracken control compromised

One of the most problematic plants is bracken, known for harbouring large tick populations.

Bracken control has become more difficult due to restrictions on Asulam, a commonly used herbicide.

“We need to work together to address the risk of disease from ticks, particularly as bracken is now harder to control,” Ms Kay said.

“We would urge the government to adopt an integrated approach to tick control.”

Ticks not only pose a danger to humans but also to wildlife and domestic animals.

In 2023, 88% of red grouse chicks in tick-prone areas had attached ticks, according to the Game & Wildlife Conservation Trust – an increase from 75% in 2022.

SLE members are actively managing vegetation and treating livestock with acaricides to limit tick numbers.

Additional measures include controlled heather burning and calls for public signage in infested areas to raise awareness.

Lyme disease symptoms include fatigue, joint pain, headaches, and a rash that may resemble a bullseye.

Early detection and removal of ticks is key to preventing infection.
