Hey, HUMAWORM does remove tapeworms, Ascaris worms, their larvae AND their eggs. The body of a Tapeworm consists of mainly reproductive organs - they also can regenerate themselves if even just their HEAD is still attached to your body. Ascaris can be hard to remove too - if he's got a BAD infestation he can do the HUMAWORM parasite cleanse every three months instead of every six months. Email me direct about the pet wormer - I'll need weight and age specifics.
