Wasps eating out leaves?

hello
we have a hedge in front of our house. it has grown very nicely on us. today, i have noticed a big looking problem with it. some yellowing, of course, which i can fix with some feeding.


but look at the leaves!!


and it is like this all through. i was standing there, scratching my head, and noticed a yellow jacket, or a wasp, landing on a leaf, and start biting on it. i might be wrong, but i came under assumption that they simply carved those holes in leaves.
now, we live next to forest and very poorly maintained properties, so ridding of the insects will not work.
any suggestions and recommendations?

PS looks like site editor is blocking parts of image code i am trying to post. just in case, here's urls:

i guess, no images, hah.... anyhow, holes all through the hedge leaves in what looks like laurels hedge.

Wasps or yellow jackets eating the leaves?? That's possible I s'pose, but more than likely the wasp or yellow jackets were going after the aphids or whatever, which were (or are) the ones that are really eating the leaves.

I would treat the wasps or yellow jackets as a BENEFICIAL insect until something proved me wrong.

lefty, that's cool. i do not kill unless i have to. that's referring to wasps. unless they bit me 8 times in one run, like they did last year.
i have noticed NO bugs what so ever on the leaves. none. yet, i have seen wasp landing on it, on undamaged part of a leaf, lowering its head onto it, and doing something that darn looked like chewing on the leaf. unless those aphids are microscopic, i have not noticed a single one of them.
with this being said, how do i treat aphids? considering amount of damage, there must be a myriad of them all over that hedge.
here's a thought though. wasps eating on fibrous leaves to create pulp for a nest? as we get nests here and there now and then.

I agree with Lefty. Wasps don't eat plant leaves and/or cause those types of holes.

You probably have aphids which can be pretty small (1/32 of a inch) or something else like aphids that is eating the plant leaves. Actually, the damage in your picture isn't too bad. Maybe the wasps are controlling the problem.

You can use pesticides (check the labels at garden centers) to control the aphids (or whatever). There are also effective natural controls that you can Google.

actually, there's wasps relative that does eat leaves. leafcutting bee. might be wild bee in my case:

Leafcutting Bee: pictures, information, classification and more

or, it can be a fungal disease, but because i saw that insect gnawing on the leaf, i am leaning towards the 1st cause:

Information on Prunus laurocerasus -- Leaf Spots and Shothole, An Online Guide to Plant Disease Control, Oregon State University

drove past a very large privacy hedge at neighbors, out of the same plant. got holes in it too, about as bad as mine.
