peppers in greenhouse being nibbled

Hi All,

This is only my second year of greenhouse growing and i have a problem, could you help?

I planted my peppers into the greenhouse from their pots and they were fine for a week then i noticed one had fallen over, when I examined it the stem had been chewed through about 1cm from the earth, a few days later and two more had suffered in the same way.

Anybody know what it is and what i might do to stop it happening to other plants.

Thanks John, I thought slugs ate leaves, didn't know they chopped the whole plant down.
A friend of mine suggested putting a trail of ash around plants as the slugs don't like to go over it, might try that before I resort to the pellets.
