How to Get Rid of Great Black Wasp | What to Do!

The great black wasp (Sphex pensylvanicus) is a beneficial insect that preys on other pests such as grasshoppers, crickets, beetles, katydids, and cicadas.

They are considered quite beautiful by insect enthusiasts due to their long black bodies measuring 1 to 2 inches in length and blue-black iridescent wings.

Due to the fact that these wasps can deliver extremely painful and swollen stings, you may wish to eliminate any that enter your home, as well as any great black wasps that hover around you or your children while you spend time outside.

Killing a Great Black Wasp Outside

  • Step 1

Protect yourself by wearing protective clothing and covering as much skin as possible. Choose from jeans, sweatpants, or slacks; footwear and socks; a long-sleeved shirt and hat.

  • Step 2

Kill one or two wasps with a wasp and hornet insecticide. Purchase a spray can that shoots 20 to 22 feet, allowing you to stand a safe distance away.

  • Step 3

Destroy a massive black wasp nest. These wasps construct burrows, and you may have noticed them flying around a particular area near the ground.

Wait until it is nearly dark and the wasps have retired to their burrows. Then, using the insecticide spray, saturate the opening to the nest and the burrow.

Another method is to dust the nest entrance with 1/4 cup insecticide dust at dawn, just before the wasps depart for the day. Prepare to flee in either case.

Killing a Great Black Wasp Indoors

  • Step 1

Getting Rid of a Great Black Wasp Indoors

Utilize a non-insecticide spray that prevents the great black wasp from flying, as you are unlikely to want to spray poison inside your home or screened-in porch.

Mint sprays that are nontoxic and extremely effective are readily available at home and garden stores. Additionally, you can saturate the wasp with a cleaning spray.

  • Step 2

Using a shoe, phone book, or other heavy object, swat the wasp. A fly swatter will be ineffective.

  • Step 3

Pick up the wasp with gloved hands or use the shoe to push it onto a fly swatter and take it outside.

Take care: These insects are notoriously difficult to kill, and the wasp may appear to be dead when it is only stunned. Once outside, squish the wasp to ensure it has expired.

While the black wasp may appear frightening, it is a truly beneficial insect that is worth learning about.

In today’s article, we’ll learn more about the black wasp, what to do if you come into contact with one, and how to get rid of it if necessary and prevent it from returning to your property permanently.

Let us begin.

What is A Black Wasp?

What is a black wasp? A black wasp on a pink flour against a green background is depicted in Figure 1.

The black wasp is a large digger wasp that is indigenous to North America.

The black wasp, scientifically known as Sphex Pensylvanicus, is a type of digger wasp that nests underground.

The black wasp, as its name implies, is a large wasp that is native to North America and is found in roughly two-thirds of the United States.

The black wasp, also known as the great black wasp, the Steel-Blue Cricket Hunter, and the Katydid Hunter, is a highly beneficial pollinator and predator that is not known to be aggressive toward humans.

Only female black wasps have the ability to sting, and they do so only when threatened or provoked, or when they believe their nest or offspring is in danger.

They are solitary wasps and are considered to be much less aggressive than many social wasps, as they do not have to defend a colony or queen.

Because great black wasps are adaptable to a variety of environments, they are found in both the western and eastern United States.

They are, however, most active throughout the year in the western United States, where the climate is consistently warmer.

As with the majority of wasps and bees, the black wasp has a lifespan of up to a year during which it passes through four life stages: egg, larvae, pupa, and adult.

Generally, a female black wasp lays one egg at a time on the abdomen of an insect that has been paralized with its stinger and left in the nest.

Once hatched, the black wasp larvae feed on the insect (which is typically a grasshopper or katydid) until it matures.

The following video discusses the fascinating and beneficial characteristics of a black wasp in greater detail.

Once the mature black wasp leaves the nest, it feeds on pollen and nectar from nearby flowers. This is especially true for female black wasps, who require a high concentration of sugary nutrients to provide the energy necessary for mating and catching the prey necessary to care for her young.

How Do You Identify A Black Wasp?

Black wasps frequently carry prey to their young, as evidenced by this female black wasp holding a katydid.

Black wasps are large, reaching a length of between 1 and 12 inches. Generally, female black wasps are slightly larger than males.

Despite their enormous size and sinister appearance, it is critical to remember that black wasps are extremely beneficial and are extremely unlikely to sting unless provoked.

Often, one of the most obvious signs of a black wasp infestation on your property is seeing one. With their large size and shiny, black bodies, these insects are difficult to miss.

They have dark grey or blue wings and a three-part body divided into a head, waist, and abdomen.

It’s not uncommon to see black wasps sipping nectar from flowers or even flying to their nests, carrying large grasshoppers or katydids.

A black wasp nest is another indicator of black wasp activity on your property, though these holes are typically small and solitary in nature.

They can resemble tiny dirt hills with holes no larger than a quarter in diameter.

As a digger wasp, the black wasp can also be seen flying low to the ground, and her nest is frequently discovered by observing where she consistently lands or brings insects.

While the majority of people will only encounter a few black wasps at a time, if your yard is particularly attractive to these large insects, you may be unknowingly inviting more.

This is why it’s just as critical to understand what attracts black wasps as it is to understand how to get rid of them.

What Has Attracted A Black Wasp To Your Yard?

Attractive to black wasps are blooming flowers and insects such as grasshoppers and katydids.

As with most insects, black wasps are drawn to areas that provide shelter, food, and an ideal location for mating and laying eggs.

Because the majority of black wasps prefer dry, soft, and easy-to-dig soil, people frequently report finding black wasps on the outskirts of gardens, in fields, or in dry patches of lawn where the grass has died and the soil is visible.

However, before a black wasp chooses a location for her nest, she will want to ensure that there is sufficient food nearby. The adult black wasp’s primary food source will be flowers.

Black wasps prefer vibrant, blooming flowers, which is unfortunate for gardeners who appreciate these lovely blooms as well. Flowers, on the other hand, are not the be-all and end-all. Female black wasps, in particular, will be on the lookout for areas with a high concentration of grasshoppers or katydids to feed their larvae.

Fortunately, black wasps do not build nests indoors, which means that having a black wasp nest inside your home will not be a problem. Of course, if a black wasp nests near your home, she may inadvertently enter through an open window or door.

If you do come across a black wasp inside, gently trap her beneath a cup and release her into your yard. Bear in mind that, while black wasps may appear frightening at first, they are beneficial pollinators and hunters with an abundance of predators. One or two of them may even aid in the growth of your garden!

If, on the other hand, you are concerned about black wasps in your yard, have no fear. We will continue to discuss how to safely and effectively remove them.

How To Prevent Future A Black Wasp In Your Home

Natural predators of the black wasp are praying mantis bugs.

Preventative measures are an excellent way to keep black wasps off your property, allowing both you and the wasp to live happily and apart from one another.

Let’s go over some of the most effective preventative measures for keeping black wasps at bay.

Plants That Repel Wasps

If you enjoy gardening but despise black wasps, you’ve come to the right place. Companion planting can help repel not only black wasps, but also other wasps and pests in your garden. Among the best plants to use to repel a black wasp are the following:

  • Lemongrass \sWormwood
  • Mint Eucalyptus Pennyroyal Basil And Marigolds

Maintain A Healthy, Lush Lawn and Stay On Top Of Mowing

As with other digger wasps, the black wasp nests in soft, dry soil. By keeping your lawn healthy and lush, you can discourage wasps from choosing your yard or property line as a nesting zone.

Regularly water it and maintain the landscaping. When necessary, fill in dry, dead patches with fertilizer or new grass seed. Additionally, you can keep your grass shorter to help repel other pests such as grasshoppers and katydids that the black wasp may be attracted to.

Attract the Predators

The fact that the black wasp has so many beneficial predators is one of the reasons it is so beneficial. You can assist in repelling and controlling black wasps and the prey they seek by inviting predators into your yard. Among these predators are the following:

  • Garden Spiders of a Large Size
  • Dragonflies \sPraying Centipedes Centipedes Centipedes Centipedes Centipedes
  • Centipedes Cent
  • Flying hovercraft
  • Lizards
  • Frogs
  • Toads \sTurtles
  • Sparrows
  • Blackbirds
  • Nighthawks And Magpies
  • Close Doors and Windows During the Warmer Months

While black wasps are not known to build nests indoors, they can gain access to your home through an open door or window.

To avoid this, close windows and doors during the summer and spring (or year-round in warmer regions).

Additionally, it is a good idea to ensure that screens are installed properly and that gaps in doorways are sealed and secured.

Manage Prey Insects Through Routine Pest Control

Bear in mind that the black wasp is a predatory insect that feeds on insects such as grasshoppers and katydids. Using a year-round pest control regimen will help you avoid not only encounters with these insects, but also with other pests. This reduces the likelihood of encountering a black wasp.

Cover Holes You Discover In The Ground Frequently

Finally, but certainly not least, patch any holes you discover in or around your property on a regular basis. Often, digger wasps such as the black wasp will reuse old rodent or snake holes to construct their nests, so avoid leaving any potential black wasp “condos” out in the open, awaiting a new tenant.

That concludes our discussion of black wasp control!

So, what are your thoughts on the colossal black wasp? Would you like to keep this beneficial insect around and allow it to do its thing in your garden, or would you rather it live its best wasp life somewhere else?
