Hornet Nest Identification

Hornet Nest Identification

Hornets’ nests aren’t hard to identify. This is because you’ll mostly find them hanging from exterior locations such as shrubs, trees, high up in the eaves, overhangs, or even below decks. The nests are typically aerial and you might also notice hornets entering and departing from the nests.


What Does a Hornets Nest Look Like?

A hornets’ nest is teardrop-shaped, light brown, and roughly the size of a basketball. The paper-like structure features hexagonal combs, an outer casing, and an entrance. Inside the nest are nesting chambers too for the queens to lay their eggs.


What Is a Hornets Nest Made Of?

What Is a Hornets Nest Made Of

Hornets construct their nests in a pretty unique way. A hornets’ nest is made of a mixture of saliva or wasp spit and wood fibers chewed together into a paper-like pulp. In addition, the nests feature 3 to 4 tiers of open-celled combs, which lie packed within a thick layered outer shell that bears a single opening at the bottom.


How Many Hornets Are in a Nest?

There are typically up to 5000 hornets in a nest, but when it gets cooler during winter, the insects abandon the nest, leaving the queen behind. The queen locates a safe retreat such as underneath tree bark, rotten wood, or inside a home.

The queen then re-emerges during springtime to build a new hive and bring forth new offspring. 


How To Tell if a Hornet’s Nest Is Empty?

How To Tell if a Hornet’s Nest Is Empty

Hornets’ nests only last a single summer, and any insects left inside during winter either freeze or die of old age. Still, you can tell a hornets’ nest is active if you find many hornets flying to and from around the entrance. 


Types of Hornet Nests

There are two main types of hornet nests, European hornet nests, and Bald-faced hornet nests. Both exhibit different nesting habits, as shown below: 

  • Bald-faced hornet nests. Bald-faced hornet hives are egg-shaped, grayish-blue, and almost 2 ft (60.96 cm) long. The bald-shaped hornets prefer to hang their nests in trees, large bushes, or shrubs about 3 ft (91.44 cm) above the ground, overhangs, building roofs, and eaves. 
  • European hornet nests. European hornets look for places sheltered from both sun and rain. They thus hide their nests in dark, hollow spaces, and only a small part of the nest remains visible. The insects nest in tree cavities, wall voids, underneath house siding, crawl spaces, sheds, or attics with the nest entrance usually more than 6 ft (182.88 cm) above ground.

Hornets and Their Nests

In the next section, we shall look at various topics related to hornets and their nests. These include the preferred nesting locations, how hornets build their nests, and at what point they depart from the nests.


Where Do Hornets Nest?

Where Do Hornets Nest

Hornets nest in different places depending on the species. Generally, the insects build the nests in sites offering lots of shade and safety from the elements. They prefer to make them in high locations or areas raised above the ground but easy to access.

Such places include:

  • Attics
  • Sheds
  • Tree branches
  • Large shrubs
  • Rooftops
  • Decking
  • Hollow tree trunks

Hornets can also nest in the ground within enclosed spaces that offer security. This includes abandoned rodent burrows, voids, and cavities in gardens, fields, and parks.

During winter, hornets nest next to tiny crevices in home siding, behind tree bark, or rotten logs. In spring, they build their nests within tree branches and below the eaves. 


How Do Hornets Make Their Nest?

Hornets make their nest by chewing wood fiber to a papery pulp and then mixing it with their starchy saliva. This results in a pulpy substance which they spread with their legs and mandibles to form the nests. 

The hornets construct their nests in areas with lots of shade and ample protection from harsh weather.


How Fast Do Hornets Build a Nest?

Hornets can take up to 3 weeks to finish creating the nest. They first have to source for the necessary construction materials like wood fiber, and then proceed to chew it until it turns into a pulp. After that, they proceed to make the nest.


When Do Hornets Leave Their Nest?

When Do Hornets Leave Their Nest

Hornets leave their nest when they look for food. They can travel between 300 and 1000 yards (274.32 and 914.4 m) from their nest when foraging for food. Mature female workers are the ones responsible for nest building and usually fly out looking for construction materials and food. 


How Far Do Hornets Travel Away From Their Nest?

Hornets travel quite some distance from their nests as they need to forage for food and nesting material. 

Hornets can travel as far as a kilometer (0.62 mi) away from their nest, though the majority generally only get to move about 200 m (656.17 ft) away. 


Are Hornets Nests Active in Winter?

Hornets’ nests are generally not active during winter as the workers die off while the queen hibernates under logs, behind siding, or in the soil. As a result, the nest becomes abandoned and remains empty and inactive during the cold winter.


Do Hornets Use the Same Nest Every Year?

Hornets don’t usually re-use old nests from previous years but build a new one instead. So, if you notice a large nest at the start of summer, it’s most likely to be an inactive nest permanently abandoned during the previous winter.


How To Find a Hornets Nest?

To find a hornets’ nest, cautiously follow active hornets back to their nesting place. They build their nests in largely undisturbed areas; hence you’ll find them in rooftops, tree branches, crevices, and beneath the ground under rocks and fallen logs.


How To Remove Hornet Nest?

How To Remove Hornet Nest

To remove hornets’ nest once you’ve located it, you can do the following steps below:

1. Wear protective clothing to prevent the hornets from stinging you. These include long sleeves and pants, gloves, and closed shoes.

2. Treat the nest by drenching or dusting before removing it. Do this at night or late evening as the hornets are less active then.

3. For an active nest, control the hornets first using a concentrated liquid insecticide plus a pyrethrin-based aerosol to spray the area around and inside the nest. The spraying will kill all the adult wasps, while the residual will eliminate any hatching wasps. 

4. Once the product is dry, you can remove the nest safely.

5. If some immature hornets remain in the nest, repeat the treatment every 2 weeks until all of them die, then remove the nest.

6. If the nest is inactive, dust the entire nest with an insecticide starting with the entrance hole. This method takes a longer time to eliminate the hornets and can take up to a few weeks, depending on the nest size. 

7. Destroy the nest and dispose of it in a polythene bag or soak it in a bucket of soapy water.

Here’s a YouTube video that shows how you can eliminate hornets for your outdoor area:

When Can You Remove a Hornet’s Nest?

How To Prevent Hornets From Making Nests?

The easiest way to prevent hornets from making nests is to eliminate nesting opportunities. Hornets get attracted to your home because it’s an ideal source for both food and shelter. Thus, they’ll nest underneath the eaves, clogged gutters, attic, and other enclosed areas. 

To prevent hornets from making nests: 

  • Keep your yard clean. 
  • Block off the entrance sites by sealing cracks and crevices.
  • Ensure all potential nesting areas are clean. 
  • Hang fake nests near potential nesting sites.
