Poo picking for horses: Why it matters for worm and disease control
When it comes to horse health, poo picking is debatably the most important job.
Whether you use a horse poo scoop, horse poo rake, or invest in a horse poo picker for larger paddocks, regularly removing droppings from your horse’s field plays a vital role in controlling worms, reducing disease risk and maintaining healthy grazing.
Many horse owners ask, “Do you have to pick up horse poo?” While it may seem like a simple yard chore, the answer is yes. Regular poo picking is one of the most effective and affordable ways to support your horse’s health and reduce pasture contamination.
In collaboration with EFECS, we’ve pulled together best practices and top tips from across the industry to create this practical guide on managing worms and disease in your fields.
Why should you pick up horse poo?
Horse droppings can quickly become a breeding ground for parasites and flies if left unmanaged.
Beyond being unsightly, manure can:
- Increase the number of worm eggs on grazing land
- Attract flies and other pests
- Damage grass quality
- Increase the risk of disease transmission
- Create rough grazing areas that horses avoid
A horse can produce around 7–9 tonnes of manure per year, meaning even a small paddock can quickly become contaminated if droppings are not removed regularly. Studies and industry guidance recommend removing droppings at least twice weekly, although daily poo picking is considered ideal where practical.

How does poo picking help control worms?
One of the biggest benefits of poo picking is breaking the lifecycle of internal parasites.
Worm eggs are passed in horse droppings before developing into larvae on surrounding pasture. Horses then ingest these larvae while grazing, allowing the cycle to continue. Regular removal of droppings helps reduce the number of worm eggs and larvae available to infect horses.
Good pasture management, alongside targeted worm testing and treatment, is considered one of the most effective ways to reduce worm burdens and help slow the development of wormer resistance.
What can you find in horse poo?
Poo picking also gives owners an opportunity to monitor their horse’s health.
Occasionally, owners may notice:
- White worms. Finding white worms in horse poo can indicate the presence of parasites, particularly following worming treatment. Some worms may be expelled after treatment and become visible in droppings.
- Red worms. Red worm in horse poo may occasionally be visible following treatment for redworm infestations. Small redworm is one of the most significant parasite threats to horses and should be managed through a testing-led worm control programme.
- Tapeworms. Owners sometimes worry about spotting a tapeworm in horse poo. Unlike some other parasites, tapeworms are not commonly seen whole in droppings. Testing is often required to determine whether a horse has a tapeworm burden.
- Worm eggs. Many owners expect to see worm eggs in horse poo, but most eggs are microscopic and cannot be seen with the naked eye. This is why faecal worm egg counts are an important part of modern worm management.
- Yellow eggs. If you notice yellow eggs in horse poo, it is worth seeking advice from your vet. In some cases, what appears to be eggs may be undigested feed material, while in others it may warrant further investigation.
Is poo picking important for disease control?
Yes. While worm control is often the main reason owners pick up droppings, removing manure can also help reduce the environmental conditions that support disease spread.
Manure attracts flies, which can act as vectors for certain diseases. It can also contaminate water sources and grazing areas if not managed correctly. Keeping fields clean helps create a healthier environment for both horses and people.
How often should you poo pick?
The ideal frequency is daily, but at a minimum, fields should be cleared twice per week. The longer droppings remain in the field, the more opportunity worm eggs have to develop and spread.
Is harrowing a replacement for poo picking?
Not always. Harrowing can help break up droppings, but it also spreads worm eggs across the pasture. Unless fields can be rested for a sufficient period and weather conditions are suitable, harrowing may actually increase parasite exposure. Many parasite management experts recommend regular poo picking as the preferred approach.
Clare Wood, Founder of EFECS, says:
“Poo picking remains one of the simplest but most effective things horse owners can do for parasite control. Regular removal of droppings helps reduce contamination on grazing, supports a testing-led worming programme and gives owners a valuable opportunity to monitor their horse’s health. Even just a few minutes each day can make a significant difference to long-term pasture hygiene.”
The bottom line
Poo picking may not be the most glamorous part of horse ownership, but it is one of the most important. Combined with regular worm testing, sensible pasture management and veterinary advice, it remains one of the most effective ways to protect your horse’s health for the long term.
