Hi Endre,
I am going to the nursery tomorrow and take a small branch and ask what I can purchase to get rid of them. I was glad to read that they do not sting. I am all for homemade recipes but I couldn't find one.
Kristin, I think taking your branch to a nursery for advice is a good idea. Hope your tree will flourish again with the right treatment!
Kristin, Sorry to hear your tree is having troubles. Hopefully it will recover once you find out how to remedy it!
All the best.

Hi Silvia,
I think that is the best choice is to ask the experts. I am not one for using chemicals as I live in the foothills and want to protect the soil and the wildlife but I might have to do something drastic.
Gloria,
I had been ignoring it as I didn't want to get stung but was glad to find out these are wasps that do not sting.
David,
Yes I hope too as my short sale closes tomorrow. I am enroute to the nursery right now to see what they say is the type of tree and what we can do to get rid of the pesky wasp like sawflies.
Take a print out of this blog post to the nursery. Maybe then can post it if they can't answer your question, but I think someone there will know. Something is eating that tree and it'll be gone quickly at this rate if it's not treated. Keep us posted!
Patricia,
Ok, what is the nursery? Is that a group in AR? I belong to a FB group called Gardening so I could post it there. I went to our local nursery and they didn't know! Thinking about going to Home Depot or Lowe's tomorrow.
They sure look a lot like yellow jackets, I'm glad they don't sting either! Otherwise I'd hand that job off to someone else.
We bought a product last night and sprayed it last night with our garden hose. It is an oily product which is supposed to give immediate relief from the pests. We will see shortly if the wasps are there this morning. Unfortunately, we noticed there are 2 other trees, REDBUD, in our neighborhood and they are infected also. I am afraid these pests will leave and then soon come back. Luckily mine happens to be the largest and fullest so I think it will survive.
First make the tree stronger: Add compost to the base but don't cover the trunk. Slow soak the soil with a drip hose not sprinklers. Inland Empire is hot in July and August, not much you can doo to protect from that...
In a used spray bottle: 2 cups water, 4 tablespoons dawn dish soap - Wear loose long sleeves and gloves and a hat (cover yourself) spray under all the leaves.
A compost tea: (Do you have a compost pile? - easy with some used wire make an upright circle and add grass, vegetable clippings, leaves) place a tray at bottom side and water the aged compost. The brownish water has nitrogen and can be used directly on the leaves at the end of the day)
Find the nest- is probably in the eaves near a swimming pool.
At night power hose it down (using caution by covering all your body wasps are mean)
Hi Caroline Gerardo
Just looked back at this post and realized I never responded. This is great advice and I am again have trouble with these sawflies that look like wasps so I will try what you mentioned above. Happy Spring!
Kristin, Your tree looks to be Japenese Cherry. If the leaves are skeltonized, it is likely the wasps you are seeing are actually sawflies. My suggestion, other than hand picking the larva, would be to use Neem oil, as it won't harms the bees and butterflies. Good luck!
