Horses are most often dewormed with a paste or gel placed on the back of the animal's mouth via a dosing syringe; feed dewormers are also used, both single-dose varieties and in a daily, "continuous" feed form. Deworming (drenching) a sheep is usually done with a specific drenching gun that squirts an anthelmintic into the sheep's throat. Recently anthelmintic herbal drugs and vaccines have been used against gastrointestinal nematodes due to an increase in resistance to anthelmintic drugs that showed significant potential against parasites in large animals.[1][2]

The Centers for Disease Control and Prevention recommends deworming treatments at 2, 4, 6, and 8 weeks of age for puppies,[4] as well as concurrent treatments given to the mother to eliminate reactivated larvae and prevent horizontal transmission from puppies that may be shedding roundworm and hookworm eggs.[5]
They also recommend deworming treatments at 3, 5, 7, and 9 weeks of age for kittens and the mother.[4]
Additionally, the Companion Animal Parasite Council (CAPC) further recommends quarterly treatments for all adult dogs and cats, depending on animal health and lifestyle factors.[6]
Humans
Mass deworming campaigns of school children have been used both as a preventive as well as a treatment method for
