Garden snail/slug eggs?

Question

I was digging up weeds in the garden, and I keep finding a tonne of snail and slug eggs under the soil

Is there any chemical-free way of destroying them, without poisoning the ground or any plants? Are they resistant to boiling water?

Answer 1

Egg shells are suppose to keep slugs away!

Answer 2

Put them in a black container (leftover pot, etc.)and let them bake in the sun.   They will then dry up and you can dump them back in the garden as an organic fertilizer additive to your soil.  Trying to boil them would make a mess....
