Why ticks matter

Ticks are blood-sucking parasites that attach to animals to feed. While small in size, they can have a significant impact on livestock health by transmitting a range of diseases.

In the UK, tick numbers and distribution are increasing, influenced by factors such as changing weather patterns, habitat changes, and reduced use of traditional control methods like sheep dipping.

Understanding ticks

There are over 20 species of ticks in the UK, with the most common being the sheep tick (Ixodes ricinus). This species is known for transmitting several important livestock diseases.

Ticks can attach to a wide range of hosts, including sheep, cattle, wildlife, and humans. They are commonly found in areas with dense vegetation, rough grazing, and humid conditions, but they are not limited to upland areas and can also be present on lowland farms.

Tick lifecycle

The sheep tick has a complex lifecycle consisting of three stages:

• Larvae – typically feed on small hosts
• Nymphs – also favour smaller animals
• Adults – feed on larger animals such as sheep and cattle

This multi-host lifecycle allows ticks to spread across different species and environments, increasing the risk of disease transmission.

Diseases spread by ticks

Ticks can transmit several serious diseases that affect livestock health and productivity:

Louping Ill

A viral disease affecting the central nervous system of sheep, causing fever, trembling, paralysis, and potentially death.

Tickborne Fever

Caused by a bacterium (Anaplasma phagocytophilum), this disease suppresses the immune system, leading to fever, reduced appetite, and increased susceptibility to other infections.

Tick Pyaemia

Primarily affecting young lambs, this condition causes abscesses in joints, tendons, and muscles, leading to lameness, paralysis, and in severe cases, death.

In addition, ticks can transmit Lyme disease, which poses a risk to humans, dogs, and horses.

Control measures

Effective tick control requires a combination of management strategies tailored to your farm.

• Use acaricide treatments on at-risk animals
• Consider vaccination where available (e.g. for louping ill)
• Develop a treatment plan based on farm-specific risk factors
• Follow manufacturer guidelines for all treatments
• Seek advice from your vet or animal health adviser

When introducing new animals, take extra care to minimise risk. Even adult sheep can be vulnerable, so appropriate treatment and timing of introduction are important.

Why planning ahead is important

Tick risk can vary depending on grazing conditions, weather patterns, and farm location. Having a clear plan in place helps reduce exposure and protect both livestock and people.

Regular monitoring and timely treatment can significantly reduce the impact of ticks on your farm.

How Herdwatch can simplify medicine recording

Managing parasite treatments effectively requires accurate and up-to-date records. Herdwatch makes it easy to log treatments and keep everything organised in one place.

Record treatments quickly

Enter details such as medicine type, dosage, and the animals treated directly into the app, reducing paperwork and saving time.

Automatic withdrawal tracking

Herdwatch automatically calculates withdrawal periods, helping ensure compliance with food safety regulations.

Stay compliant and organised

Generate reports for inspections and audits, and use reminders to stay on top of treatment schedules.

Protect your livestock from tick-borne disease

Ticks are an ongoing challenge for livestock farmers, but with the right knowledge and control measures, their impact can be reduced.

Combining good parasite management with accurate record keeping helps protect herd health, improve productivity, and support long-term farm performance.
