What are Spider Wasps?

Spider wasps are a type of hornet belonging to the family of yellow jackets. They have dark, almost black-colored bodies and are comparatively larger.

These kinds of wasps have longer legs and dark-colored wings, which they use to take off. In most cases, you will likely notice them feeding on the nectar of the flowers in your garden. If you are wondering where spider wasps get their name from, it is because they prey on spiders.

The female spider wasps prey on the spiders, stinging them until they become paralyzed. Once killed, the wasp drags the spider to their nest, where it lays the eggs. The paralyzed (and dead) spider serves as a food source for the babies when they hatch.

Are Spider Wasps Poisonous?

Given how terrifying spider wasps look, it isn’t surprising that most people have one question in their mind, “Are spider wasps poisonous?”

Spider wasps do sting human beings if they are disturbed by them. Their sting will cause a significant amount of pain. That said, spider wasps aren’t poisonous to human beings. So, if you are worried that their sting will kill you, be assured that it won’t.

One unique thing about spider wasps is that they lead a solitary life. This means there are very few chances that they will cause an infestation in or around your house.

Do Spider Wasps Damage the Garden?

If you notice recurrent visits from spider wasps in your garden, wondering whether or not they will damage the yard is relatively common.

That said, female spider wasps tend to lay their eggs in nests they make in the soil. They create little soil burrows where they lay the eggs, which means that they won’t cause much damage to the plants or even the soil in your garden.

Since spider wasps prey on spiders, they are a great addition to your garden because they will most likely keep the spider population in check. They also don’t colonize and live in large groups, meaning you won’t have to worry about the risk of infestation.

How to Eliminate Spider Wasps from Your Garden

As we mentioned before, spider wasps are solitary insects, which means they won’t become a nuisance to your surroundings. You won’t have to worry about eliminating them because they come and go from time to time.

Even if you notice a spider wasp in your garden, chances are that it’s alone and will prey on a spider and leave within some time.

The best thing we’d recommend you do is to let them be. Since they aren’t a threat to humans and don’t create colonies, it is ideal that you leave them alone, and they will most likely go away by themselves after some time.

However, if you want to take extra measures, spray the entire garden with water until the soil turns a little muddy. Spider wasps don’t like laying their eggs in muddy soil, making your garden inhabitable for them.

One important thing you should avoid is spraying chemical pesticides or insecticides. They might successfully drive the wasp out of the garden but leave a chemical residue, which makes the garden inhabitable for other pests and insects that are essential for the plant’s growth.
