RE: [RC] [RC] Ivermectin not working for pinworms! No tail left... - Nancy MittsI went through that with my mare last summer, but she was in a different (1 acre) field than the other horses which made it easier to treat. Are all three of yours running together? Are you seeing the yellowish gunk around their anus from the worms? If not, then it may be something else.I figured she picked them up while grazing at a camp and then continued re-infecting herself. Strongid (or generic equivalent pyrantel pamoate) worked better than the ivermectin. (Zimectrin Gold didn't work either) Deworm every 18 days, because it only kills the later stages, and the horses are probably still continually ingesting more. I did this 3 times and then stopped, and in 8 weeks she was itching again so I did it 3 more times, 18 days apart each time, then went back on the every 8 week ivermectin cycle. I may have used Safegaurd (fenbendazole) one time because I was out of the other and felt it was more important to keep on the 18 days, The key is to keep on the 18 day cycle long enough for them to "clean" the field, because the worming only kills them in their later stages as they mature. If you break the cycle and stop too soon like I did the first time, I gave some a chance to mature and lay eggs ( or whatever they do) and reinfect the field. I have not had any problem this summer, except when ticks got in their tails.
