Is this a wasp, hornet, or yellow jacket and how do I get rid of them!? - Knowledgebase Question

Question by Paradox5154
September 2, 2017
We have a large amount of wasps, hornets, or yellow jackets in a tree in our front yard and I want to get rid of them to make sure they don't sting my 2 year old son or me when I am mowing. Could you please help me identify what this is and how I get rid of it? Note, it is a pretty large tree and these things are all over it, I am not sure arasol cans will work, I will need A LOT of them! Also note, I wouldn't care if they didn't pose a risk to my son and I but they do.

Thanks for your help!

Edit - a couple more details for my woefully vague post. I will post another picture of the one I got with a quarter and tape measure by it but it looks to be just shy of an inch curled up, my guessay is probably an in and a half when straightened out. When I say they are all over, I believe them to be nesting, not hunting. They are basically on every branch of the tree, not like a swarm that comes and goes. I believe the tree is aN oak tree but am open to correction. On that as I am not really one for much plant knowledge. My wife says it has "oak galls" I don't know if those are nests for these things or not but they are also all over the tree. I will post more images of several of these things.

Please, what is the size of this? Also, when you say they are "all over the tree" do you mean they are making a nest in the tree or are they hunting for prey in the tree? Maybe knowing what kind of tree might help, too. Thanks.

Do you know if you by chance have Cicada's in your area? I'm not sure what it is but it reminds me a lot of a Cicada Killer Wasp. We have Cicada's here during the summer and the Cicada Wasps seem to be around in July and August. The females dig burrows/nests in the lawn. They kill cicadas and place them in the nest for the larvae to eat. The first time I saw those wasps they really scared me because there were so many flying around ... but luckily they don't appear aggressive. I've always been afraid of getting stung by wasps since getting a bad sting as a child so they really rattled me at first. Now, I walk around the yard with quite a few of them flying around and I've never been stung. You can read about them here:

Thanks, it does look a lot like your picture. It is interesting, I mow the lawn all the time and haven't ever noticed a nest lime you posted on the ground. I will need to take a better look in tomorrow's daylight. Thanks!

Your wasp looks like a sand wasp.
There are a number of sand wasp varieties, all seem to be lone nesters, capturing caterpillars for their children, and pollinating all the flowers in the garden.
You're going to want to encourage these.
Having native pollinators in the garden means not having to laboriously hand pollinate the produce.

It does look like a Cicada killer wasp but I don't think they swarm and are pretty much harmless unless you are a Cicada.

To get rid of them, you would have to find the nests somewhere in the ground in your yard. Then go back at night and use some wasp spray - fill up the hole with spray.

Thanks for the help! I will have to look for nests somewhere. I have never noticed anything other than the "oak galls" in the tree and figured that was the nest.

That is a different (tiny, harmless) wasp.
