Chillip plant problems in the greenhouse

[Theball]

I have recently moved house and I inherited a greenhouse with the property.

I have got many varities of chilli plants growing but something seems to be eating the leaves of the plants. My tomato plants are however unaffected by this.

I cannot see any bugs at all

can anybody help me before I go crazy

Slugs, snails most likely, even if you don't see the slimy trails.

Pop out there after dark tonight and see what you find

Might help if you post a photo of the damage. Probably snails though.
