We have relaunched our popular Equine Worming Programme for 2025-26. 

Why is worm control important?

Many worms can affect our horses’ health, causing coughing, diarrhoea, “girthy-ness”, skin issues and problems with circulation. The most serious issues are colic signs caused by blockages from worms, or damage to the guts from mass emergence in the spring. This can be fatal.

What is included in the worming plan?

  • A tailor-made pack for your horse(s)
  • 4 worm egg counts per horse using our in-house faecal analysis machine
  • A redworm blood test including a free visit
  • A tapeworm saliva test
  • Advice from our experienced equine vets
  • Reminders when your tests are due
  • Quick turnaround time for your results
  • Discounted weighing
  • Notifications that your horse needs a wormer
  • A range of wormers available to buy same day or next day direct from us

All for a one-off payment of just £175 (inc. VAT), saving you money and offering your horse important preventative healthcare!

This programme is designed for adult horses and ponies. If you have horses and ponies under 3 years old or pregnant mares, please let us know so we can tailor the programme to them.

Our Worming Programme is under constant review based on reports of resistance to different groups of anthelmintics and weather conditions.

There is growing evidence that all types of worms are developing resistance to the wormers that we have available for horses.  We can use worm egg counts, saliva and serum testing to identify the horses most at risk of worm damage.

Targeted worming will reduce the number of resistant worms in your fields, meaning your wormers will be more effective and you will need to give wormers less often.

In addition to overuse of wormers, worming for the incorrect weight is a major cause of resistance to wormers. The most accurate way to get a weight from your horse is for us to use our portable weighbridge. This can also help with accurate dosing for medications other than wormers.

Another way to reduce your horses’ worm burden is to remove droppings from their pasture at least twice a week.  Larvae can survive a few weeks in hot weather but will remain infective for 6-9months if protected by cold weather.

  1. Payment must be made in full at the time of application.
  2. You may cancel your plan and receive a refund for unused products only under the following circumstances: you move your horse outside the normal geographical area covered by MacArthur Barstow & Gibbs; your horse is sold; or upon the death of your horse.
  3. Wormers supplied on the plan are only for the horse(s) named on the plan. You will receive a reminder when your wormer is ready to collect. The number and type of wormers supplied each year may vary.
  4. Please note – all wormers are supplied as ‘oral paste’. There may be additional charges for tablets or powder if such an alternative is available.
