Hornet Control and Safe Nest Removal

Hornets are the largest wasps in the UK. Like other social wasps, they build nests by chewing wood into a papery pulp. Each nest contains one queen, who lays eggs while worker hornets maintain the colony. Most species build exposed nests in trees and shrubs, but some use underground cavities or sheltered spaces. During winter, nests die off, and lone queens hibernate in lofts or leaf litter until spring.

The Risks of Hornet Infestations

Hornets aggressively defend their nests when threatened. This makes them a serious risk when nesting near homes, gardens, or public spaces. Their stings are more painful and dangerous than those of wasps or bees, posing threats to people and pets.

Preventing Hornet Nests

Keeping hornets away can be difficult once they establish a nest. However, a few precautions can help:

• Keep windows and doors closed or use fly screens in summer.
• Cover outdoor bins to avoid attracting hornets searching for food.
• Regularly inspect trees, sheds, and roof spaces for early signs of nests.

Safe Nest Removal – What Not to Do

Removing a hornet nest without the right knowledge or equipment is dangerous. Keep these key points in mind:

• Do not disturb a nest unless it poses a serious threat. Hornets help control pest populations and benefit wildlife.
• Do not remove a nest during daylight hours. Hornets are most active then and will attack if disturbed.
• Do not attempt to burn a nest. This is highly dangerous and ineffective.

Safe Nest Removal – What to Do

If removing a nest yourself, follow these safety measures:

• Wear protective clothing, including a beekeeping suit, gloves, and a face veil.
• Use a sturdy ladder and have someone hold it for stability.
• Remove the nest after sunset when hornets are less active.
• Use long-handled shears to cut down the nest and place it in a sealed bin bag.

Professional Hornet Control

Even with precautions, removing a nest remains risky. Disturbing hornets can lead to multiple painful stings and aggressive swarming. Professional pest controllers have the right equipment, protective clothing, and high-strength insecticides unavailable to the public.

When to Seek Expert Help

Check for nests in early spring when they are smaller and easier to manage. If a nest appears near your home and poses a safety risk, contact pest control specialists. Trained professionals ensure safe and effective removal with minimal risk.

For those considering DIY treatment, insecticides in sprays, liquids, or dusts can be applied to nests. However, it is safest to attempt this in autumn or winter when hornet activity is low. At other times, professional assistance is the best option for safe and thorough removal.

DO HORNETS CARRY DISEASES?

Hornets, while primarily known for their painful stings, can also pose a health risk due to their ability to spread bacteria. Unlike other pests that are direct disease carriers, hornets contribute to the spread of harmful pathogens by contaminating food sources and surfaces.

Potential Health Risks

• Bacterial Contamination – Hornets often scavenge from decomposing organic matter, rubbish bins, and even animal carcasses. As they move between these areas and human food sources, they can transfer bacteria such as Escherichia coli (E. coli) and Salmonella, which can cause food poisoning.
• Venom Allergies and Anaphylaxis – A hornet’s sting injects venom that can cause severe allergic reactions in some individuals. While most people experience swelling and pain, those allergic to hornet venom may suffer from anaphylaxis, a life-threatening condition requiring immediate medical attention.
• Secondary Infections – A hornet sting can break the skin, creating an entry point for bacteria such as Staphylococcus aureus, potentially leading to skin infections like cellulitis or abscesses if not properly cleaned and treated.

Where Hornets Nest

Hornets prefer to build their nests in sheltered locations such as:

• Hollow trees
• Roof spaces and attics
• Wall cavities
• Sheds and outbuildings
• Dense bushes and hedgerows

Unlike wasps, hornets are generally less aggressive unless they feel their nest is threatened. However, their larger size and potent venom make them a more dangerous pest when provoked.

Managing a Hornet Infestation

Due to the risks associated with hornet stings and their aggressive defence of nests, professional removal is strongly recommended. Attempting to remove a nest without the proper protective equipment and knowledge can result in multiple stings, increasing the risk of severe reactions.

If you suspect a hornet nest on your property, it is best to seek professional pest control services to safely and effectively eliminate the threat.
