Are you terrified to find a large wasp sitting idly on a tree in your lawn or garden? Well, here’s how to get rid of ichneumon wasps and, more importantly, whether there is anything to be terrified of or not.
Finding a wasp in your garden or yard can be terrifying, especially if you have pets or children at home. But if you have ever seen the black giant ichneumon wasp, you would know that terror has a new name.
That’s unfortunate because these wasps are actually nothing but beneficial to us and will probably never cause any damage to you or your family.
However, if you would still prefer to get rid of it from your property, read on.
What Are They?
Ichneumon wasps are a species of parasitic wasps that live all across the north and central North America in places that have lots of trees.
Their most conspicuous feature is the huge ovipositors on the head of the female, which most people assume to be stingers.
These appendages can be as long as five inches, much more than the rest of the body of the wasp (which is normally about a couple of inches in length (around 1.5 inches).
These ovipositors do have another, more insidious purpose. They help to place the eggs of these wasps into other insects, like caterpillars or grubs.
Ichneumon wasps simply use the other host insects to lay their eggs, and when the eggs hatch, the larvae feed off the other insect, pupate and then come out as adult wasps.
Since they don’t lay eggs in a nest of their own, these wasps have no need to be social. They don’t come together to terrorize humans like bees or hornets.
You will usually find each of them flitting around separately with no other of their species in sight.
Where Do They Come From?
Female wasps lay their eggs in the body of other insects, so if you find grubs or caterpillars in your garden, get ready to hose these ichneumon wasps too.
While their natural habitats are forests and trees, in recent years, due to deforestation, these bugs have started making a home near human settlements as well.
The ichneumon larvae take the entire winter to feed off these poor creatures, and in the spring and summer, they come out as adults, lay more eggs, and then die.
Do You Need To Get Rid of Them?
So we know now that these bugs help finish off other pests, which begs the question: do you need to get rid of them at all? Let’s figure it out.
Do They Sting or Bite?
Rarely do ichneumon wasps attack humans. Most actually don’t have stingers, so they can’t sting or bite. They can be intimidating to look at, but they are mostly afraid of humans and will flutter away if they see them coming.
Very few ichneumon wasps have stingers, which, if you try to harm them, they might want to use. But in general, they don’t relish the idea of fighting creatures 20 times their size.
Female ichneumons are often mistaken to have stingers because of their large ovipositors, but these appendages are totally harmless.
Are They Poisonous or Venomous?
No, none of these wasps are poisonous or venomous. Even the few that can sting will not cause much more than a painful rash. You might need to put on some aloe or an ice pack to make the pain subside for a bit.
Are They Harmful To Humans in any Way?
No, they are harmless. In fact, their parasitic nature is actually quite beneficial to humans, especially gardeners and those with plants around.
They are often prey to larger bugs like praying mantises, and their larvae are also prey to ants, spiders, and other insects.
How Are Ichneumon Wasps Helpful to Us?
These beneficial wasps have much to offer gardeners and plant lovers. Some of these benefits include:
They feed off other insects: Ichneumon wasps eat many powerful pests of plants, such as boll weevils, wood borers, and hornworms. They can also sometimes feed on spiders.
They lay their eggs in other insects: Typically, the ichneumon wasp will choose a caterpillar or a grub to place her eggs. These eggs hatch to form wasp larvae, which then eat the pest from inside out, leaving nothing but a shell.
They pollinate your plants: Many ichneumon wasps are also good pollinators who would spread pollen to other parts of your garden, helping plants grow.
What To Do If You Want To Control Them?
Despite the long prologue we have made in getting to this part, if you still feel that you need to get rid of ichneumon wasps, here is what you should do.
These wasps lay their eggs on grubs, worms, caterpillars, and other such insects. By using regular treatment in your garden, you can eliminate the population of such bugs.
If you get rid of these insects, ichneumons won’t have any place to put their eggs, and they will have to move out of your garden.
Natural insecticides like neem oil, diatomaceous earth, vinegar, or soapy water will often do the trick.
If you want to spray the wasps directly with insecticides, the best time to do so is in the evening or night, when they are less active.

Frequently Asked Questions
How do you get rid of parasitic wasps?
There is actually no need to get rid of them. However, if you want to get it done, you need to control the pest population in your garden first.
Once the pests are gone, the wasps will surely also be gone very quickly. If there are only one or two wasps in your garden, swatting them with a heavy object would also work!
Do ichneumon wasps have nests?
No, they don’t have any nests. Ichneumon wasps lay their eggs directly on insects like caterpillars, mealworms, earthworms, grubs, etc.
Since they don’t need a place to lay their eggs, they never bother to make them. They aren’t social either, because of the same reason.
Can ichneumon wasps sting you?
Most ichneumon wasps don’t have stingers. The female ones have long ovipositors, which they use to lay their eggs but have nothing to do with stinging.
For the few that have stingers, they are mostly harmless and will not approach humans unless the human tries to attack them for some reason.
Are ichneumon wasps beneficial?
They are one of the most beneficial insects to have in your garden. They are able to control the population of most pests quickly, efficiently, and without needing to spend time or money on using chemical insecticides. They keep you safe from insecticides as well.
Wrap Up
There is really no reason for you to try and get rid of ichneumon wasps. These bugs are a powerhouse of pest killing and do the job that most other insecticides cannot do easily.
They will take care of grubs, worms, and other plant-eating insects in a few days’ time. But if you still want to get rid of them, just remove the pests from your garden with some effective pesticides! Thank you for reading.
