Stink bugs on tomato plants

[Filbert]

Hello all. I'm watering plants for friends during the summer holidays and have discovered (after checking google images) that some of the cherry tomato plants are covered in stink bugs. What can I do to get rid of them. The tomatoes were planted by children and normally they look after them so I don't want anything too toxic. The tomatoes are outdoors, not in a greenhouse. I go every 2 days to water them and on Friday there was nothing. Today, 2 of the plants were covered. I tried hosing them off but to no avail. Has anyone any ideas? By the way I now live in Spain not the Uk. Thanks in advance.

If they're the type of shield bugs (otherwise known as stink bugs) which are native here in the UK, there's no need to do anything. They're harmless:

Thanks for the prompt reply but unfortunately it looks like that they're the southern ones :-(
