There are two schools of thought that are actually pretty similiar. I think everyone agrees that wormers need to be rotated so that you aren't allowing your horses to build an immunity to any of them. Some people (like me) use a different wormer every year - so this year is my Quest year and I will give Quest every 3 months and give Ivermectin probably Jan 1 (to get the bots) Next year will be my Ivermectin year and I will give Ivermectin every 2 months then the next year will be my Strongid year. Other people like to rotate the wormers within the year. Ivermectin, then Strongid (or whatever the generic is) and Quest. Just be sure to give Ivermectin sometime after the first really good frost. -- Laree in NC Doppa & Mura Simon, Sadie and Sam (the "S" gang) "Yet when all the books have been read and reread, it boils down to the horse, his human companion, and what goes on between them." - William Farley "I ride ponies because heart is not measured in hands." - Steve Edwards
