Starting Your Worm Control Plan

Now that we have seen all of the components required to make an effective worm control programme, it is time to put it all together and begin your own plan. I have created the following table as a guideline to help you start, it is not set in stone and can be 'tweeked' to suit your individual circumstances.

Please use the notes underneath the table to help you with your worm control plan and make sure you have Pasture Control Measures in place.

1.    Please note that the information provided above is based on current worming advice and is intended for use as a guideline only for the routine control of worms in healthy adults horses. If your horse is showing any signs of illness, has any underlying health issues or you suspect that your horse has a high worm burden you must consult your veterinary surgeon before worming.

2.    The product you use should be suitable for your animal, some wormers are not suitable for foals, pregnant/lactating mares or other types of equine. Please check the manufacturer's datasheet (within the listing for each of our wormers) before purchasing your wormer, message me if not sure.

3.    If you are new to targeted worming I recommend using WECs every time worming is due (or overdue) during the grazing season, however, as time goes on you may find that you don't need to use WECs as often. It is still advisable to do spot checks and make sure that at least one WEC is carried out for each horse annually.

4.    If you are consistently getting WEC counts above 200epg please use our trouble shooting guide to help.
