Tayberries

I've just been out to inspect the tayberries and the bush is alive with what appear to be small/young wasps. So much so I daren't try to pick any. Not too unusual, but these wasps seem to be actually eating the berries. Any comments?

When I was young, we used to do this to trap wasps.

Take an old jam jar (1lb or 2lb).
If there was a still a scraping of jam left, then fine.
If not put in a teaspoon of any jam you don't care about too much.

Fill about one third full with water and give a swirl.

If you've got a metal lid, make a hole about half an inch in diameter in the centre of it, and put on the jar.
If you've not got a metal lid, use brown paper and string or a rubber band to make a lid, and then make the hole in that.

Place near fruit tree, but not too close.

Leave till autumn.

Remove lid; pour contents onto compost heap.
