Clear muck from the field on a regular basis, preferably daily but at least once a week.Muck from horses with a tapeworm burden remaining on the paddock will increase the potential for oribatid mites to become infected and therefore will also increase the risk of horses becoming reinfected after worming.
Restrict grazing while away from home, such as at pony club or grazing at show grounds. You won’t know the levels of tapeworm-infected oribatid mites present.
Ensure that wormers are not under-dosed which would result in persistent burdens.
Test for tapeworm and only treat those horses that are diagnosed with a burden. Retest within 2-3 months to ensure worming has been effective.
New horses to your paddock should always be tested, and wormed where appropriate, before they have access to grazing.
