What does a worm do for soil?

pour bleach on the soil wait about 15 min they will come to the top EDIT: WHY would you want to get rid of them - they aerate the soil by creating tiny tunnels as the move. Also - they eat decaying...

depend what worms you mean yes the worms as in your garden worm but no not the worm in your belly you get them from not washing your hands

earthworms need a dark cool moist home and being underground is their best bet at survival to live

yes they are very important because when they make fices it helps the soil.

Earthworms eat the soil, and excrete what they don't digest - leaving tiny piles of 'worm-poop' in the soil. This breaks down and adds to the general composition of the soil.
