 How is the best way to deal with these? if they carry on munching like they are there will not be much left.

thanks

Edit to shorten long link

If you are growing Brassicas you won't have corn earworms  I don't think it's a pest we get in the UK (at least I can't find any references to it here)

They'll probably be the caterpillars of the cabbage white butterfly.

It's best to cover your brassicas with fine netting to stop them getting on there in the first place.
Now your options are to pick them off and squash them or RHS shows

Spray with pyrethrum (Py Spray Garden Insect Killer) Scotts Bug Clear Gun for Fruit & Veg,

Check the container for how many times you are allowed to spray the crop each year though.

Could it be these, http://ukmoths.org.uk/show.php?id=4433

I favour Pick & Squish for caterpillar control.
