Bald-faced hornets ( Dolichovespula maculata) are large, intimidating-looking insects. Their nests, however, are even more striking. Finding a bald-faced hornet nest can be crucial if you need to remove it due to safety concerns. But locating them safely requires caution and awareness. This guide provides a step-by-step process for locating these nests, focusing on safety and responsible removal.

Understanding Bald-Faced Hornet Nests

Bald-faced hornet nests are easily recognizable. They're large, papery structures, often described as resembling an upside-down teardrop or a gray, football-sized pear. They are usually built high up, often in trees, shrubs, or even under eaves or decks. The nests are enclosed, unlike the open-comb nests of yellow jackets. Understanding their preferred nesting locations is key to finding them.

Identifying Bald-Faced Hornet Activity

Before embarking on a nest hunt, look for signs of hornet activity. These might include:

Hornets themselves: Spotting several bald-faced hornets flying in a concentrated area suggests a nearby nest. Pay attention to their flight patterns. They often fly in straight lines between the nest and food sources.
Nest materials: Look for bits of gray papery material near possible nest sites. This indicates they are actively building or repairing their nest.
Entrance holes: Bald-faced hornet nests have a single, easily identifiable entrance hole at the bottom of the structure.

Locating the Bald-Faced Hornet Nest: A Step-by-Step Approach

Finding a bald-faced hornet nest requires careful observation and a methodical approach. Remember, safety is paramount. Never attempt to locate or remove a nest without proper protective gear.

Step 1: Observe Hornet Traffic

Spend some time observing the hornets' activity. Note where they seem to be coming and going from. This will often lead you to the general vicinity of the nest.

Step 2: Follow the Flight Paths

Gently follow the flight paths of the hornets. Do they seem to be heading towards a specific tree, shrub, or building structure? This will narrow down your search area significantly.

Step 3: Systematic Search

Systematically search the areas you've identified. Carefully examine trees, shrubs, eaves, attics, and other potential nesting sites. Look for the characteristic gray papery structure and the single entrance hole.

Step 4: Use Binoculars (Optional)

If the potential nesting site is high up or difficult to access, binoculars can be extremely helpful in safely confirming the presence of a bald-faced hornet nest.

Places Bald-Faced Hornets Commonly Nest:

High in trees: Often in the branches, away from direct sunlight and rain.
Shrubs and bushes: Providing natural camouflage and protection.
Under eaves and overhangs: Offering shelter and protection from the elements.
In attics and wall voids: Especially in sheltered, quiet locations.
On utility poles or fences: Less common, but still possible.

What to Do After Finding a Bald-Faced Hornet Nest

Once you've located the nest, do not attempt to remove it yourself unless you have extensive experience and proper protective gear. Bald-faced hornets can be aggressive when their nest is threatened. Contact a pest control professional for safe and effective removal. They have the necessary equipment and expertise to handle the situation safely.

Safety Precautions

Wear protective clothing: This includes a beekeeping suit, gloves, and a hat with a veil.
Work during cooler times of day: Hornets are less active early in the morning or late in the evening.
Avoid sudden movements: Sudden movements can agitate the hornets.
Keep calm and move slowly: This will reduce the chance of being stung.

Finding a bald-faced hornet nest is best left to professionals. However, understanding their behavior and nesting habits can make the process safer and more efficient for those who need to locate the nests. Always prioritize safety and consult professionals for removal.
