You cant get rid of worm eggs, it's impossible.I still need advice on how to get rid of worms eggs in my backyard. Never ending problem those worms.
Insects are the main vectors for tapeworm eggs. They are the intermediate host. You can try spraying your backyard to cut back on the insect population and not necessarily with chemicals. You can use a liquid soap spray or neem oil mixture which are examples of non toxic sprays that will effectively kill insects.
