Bald-faced Hornet Nest Removal | Can I Remove a Hornet's Nest Myself?

Written by EcoShield Pest Solutions | Jul 29, 2022 1:52:00 PM

Known for their large size and notably painful stings, bald-faced hornets are warm-weather pests with a reputation that precedes them. While these hornets become active as soon as the weather starts to become mild, it’s not until mid-to-late summer that the population grows abundant. When this happens, it may be tempting to take matters into your own hands, especially if you’ve located the bald-faced hornet’s nest. In this blog, we’ll explain why DIY bald-faced hornet nest removal may not be the best solution to your concerns. 

 

What are bald-faced hornets and where do they live?

Bald-faced hornets, or Dolichovespula maculata, are actually not hornets at all. Also commonly referred to as a white-faced hornet, white-tailed hornet, bald-faced yellowjacket, bullwasp, or even blackjacket, the bald-faced hornet is a relative of the yellowjacket and part of the wasp family. Because they are much larger than yellowjackets and not yellow, but rather black with white faces and “tails,” they received the name “bald-faced hornet.” Despite their deceptive appearance, they are yellowjackets at their core and share many of the same behaviors and characteristics associated with yellowjackets. 

Bald-faced hornets generally grow to a little over ½” in length in adulthood, while the queen grows much larger (nearing a full inch.) Like most other wasps, they have a long, pinched body and a triangular upper mid-abdomen. They also have six legs and two antennae. As mentioned, bald-faced hornets have a unique and striking coloring that sets them apart from other yellowjackets. Predominantly black in color, bald-faced hornets (as their name suggests) have mostly white faces along with white spotting throughout their abdomen and white striped “tails.” This unconventional pattern is where many of the bald-faced hornet's other pseudonyms come from – i.e. white-tailed hornet and blackjacket. 

Geographically, bald-faced hornets can be found throughout most of the United States as well as Canada. While more common in the southeastern part of the US, bald-faced hornets are known to live on the west coast, throughout the Rockies, and are prevalent on the east coast as well. Unfortunately, this means nearly anyone is at risk of encountering a bald-faced hornet – or worse, having a colony of bald-faced hornets take up residence in or around their home! 

Are bald-faced hornets aggressive or dangerous?

It’s important to understand that while bald-faced hornets don’t closely resemble yellowjackets, their behaviors are very much alike. Like yellowjackets, bald-faced hornets are extremely territorial and will not hesitate to sting anyone who ventures too close. They have the ability to sting multiple times and do not lose their stinger. This poses a particularly dangerous situation to those who unknowingly agitate a bald-faced hornet, as even close proximity to the hornet’s nest will be perceived as a threat. In addition, it makes safe removal of a bald-faced hornet’s nest nearly impossible without the help of professional pest control. 

Bald-faced hornet stings are extremely painful, and the venom can trigger pain receptors, causing inflammation and, for some, allergic reactions. If you are stung by a bald-faced hornet and are concerned about a reaction, please contact your doctor immediately. 

It should also be noted that the bald-faced hornet’s aggression does not end at adults trying to remove unwanted nests – in fact, they will sting anyone (or anything) that they perceive as a threat. This includes unsuspecting children who accidentally wander near a nest or pets who find themselves in the wrong place. Cats or dogs who spend any amount of time outdoors during the summer are equally at risk of a bald-faced hornet’s sting.

If your pet has been stung by a bald-faced hornet or other stinging insects, we strongly encourage you to contact a trusted vet as soon as possible. 

Where do bald-faced hornets build their nests? 

Bald-faced hornets are social insects and are active during the day. You may be able to track down their nest by simply watching where they buzz around, but they also tend to nest in some predictable spots. Bald-faced hornets often build nests in high-reaching places where they feel most protected from predators and the elements. Generally at least three feet or more above the ground, some common nesting locations include tree hollows, dense bushes or shrubs, along fence crevices, in sheds, under outdoor lights, or even under the eaves of buildings (including homes!) Unfortunately, these hard-to-reach locations often make DIY nest removal exceptionally difficult for homeowners. This is especially true when you consider that a single nest can contain up to 400 worker hornets!

You can spot a bald-faced hornet’s nest by its large, oblong shape and paper-like construction. Bald-faced hornet’s nests are often shaped much like footballs and can grow as large as 3 feet across as the colony population expands. The nests are made of chewed-up bark or rotting wood – when masticated and mixed with the hornet’s saliva, a wood paste is made and used to form the nest. This gives the nests a brittle, almost paper mâché-like appearance on the outside. By design, it’s likely you won't be able to see the comb-like structure beneath the wood pulp exterior, which serves as protection for those within the nest. 

Please be aware that even as summer comes to an end, it doesn’t mean bald-faced hornet concerns disappear. As the weather begins to cool, bald-faced hornet Queens will seek a warm, comfortable place to overwinter. Personal residences and homes are often targets for Queen hornets due to their consistent mild temperatures and safety from the elements. If you do not resolve a bald-faced hornet problem near your home during the summer, it’s possible the Queen may not venture far when winter approaches. Your home may be the nearest, most comfortable place to reside during the cold season.

Why shouldn't I remove a bald-faced hornet’s nest myself?

If the 400 territorial worker hornets residing within the nest aren’t enough to make you reconsider, you may wonder why you can’t just remove the nest yourself. The reality is, that you may be able to knock the nest down on your own, but the likelihood of doing so without causing you or your family harm is very slim. Bald-faced hornet removal is tricky to do yourself, and it’s unlikely you’ll be able to do so without being stung. Here’s why:

  • At-home sprays have limited spraying distance. You’ll probably want to attempt to kill the hornets from a great distance for safety reasons. Unfortunately, off-the-shelf sprays rarely provide the spraying distance needed to safely eliminate the hornets. It can also be incredibly difficult to maintain accurate aim when spraying from afar, even if you do find a can that can close the 25+ foot gap you need. 
  • Slow or weak spraying power. Some sprays may claim they have the force to knock down nests from afar or kill on contact, but this isn’t necessarily the case. Even if you knock down the nest, you’ll still have up to 400 angry hornets coming your way. And even if your spray makes contact with the hornets, they can often live long enough to fly a short distance to attack their target. 
  • Sprays don’t make it inside the nest. Making contact with the exterior of the nest alone isn’t enough to solve the problem. In reality, you’ll need to spray inside the nest to reach the bald-faced hornets and (hopefully) eliminate them. Your spray may be effective in killing “on contact,” but spraying into a nest at a distance is a difficult feat. Even worse, if you miss and hit the outside of the nest, you may antagonize the hornets and send them after you. 

In general, DIY bald-faced hornet removal is a bad idea for those who would prefer not to be stung. At best, you get rid of the nest and kill a few hornets but suffer a bald-faced hornet attack by the survivors. At worst, you don’t even knock down the nest or kill any hornets and still get stung by aggressive bald-faced hornets. We don’t like those odds. Do you?
