The soil association recommend that rotational and multi-species
grazing should be used to control worms in order to prevent the routine use of
wormers and other veterinary treatments. Where five or more horses are kept on the
organic holding, a pasture management plan addressing the control of internal
worms and a health plan will be required.
Where five or more horses are kept, the use of
avermectin-based products for the control of worms is restricted. No restrictions apply where less than five
animals are kept but in all cases animals must be housed or dung removed from
the pasture for 48 hours after treatment with avermectin products.
Here are the wormers from the avermectin family
(they use ivermectin as the active ingredient) currently supplied by

Herbal wormers
Herbal worming products are now available. These use a combination of plants to repel
parasites. No scientific data is
available on how effective these preparations are in combating worm burdens. It is therefore best to gain expert advice
before relying on herbal products:
