Caterpillars in the greenhouse

[David]

Morning all,

Since the hot weather began I have been leaving the greenhouse door open so I get a draught between it and the auto-vent, this morning Ive returned from a trip away to find that caterpillars (only found two so far so not a plague) have been having a go at my tomatoes. They've eaten leaves and drilled right through some of my big Legend and Marmande.

Darned annoying so I wonder if I should have done something to protect them?

Any ideas gratefully receieved.

I have the same problem too.

While I'm watering or pinching out I look out for the tell tale signs of caterpiller poo and generally find the caterpillar just above. It then gets disposed of underfoot

Otherwise insect netting to stop the butterflies or tomato moth (in this case) getting in.
