How to Effectively Remove Underground Wasp Nests

Sharing is caring!

Dealing with wasps can be daunting, especially when their nests are hidden underground. These subterranean fortresses are a common feature in quieter corners of gardens and lawns, housing colonies that can become aggressive if disturbed.

Removing these nests safely is crucial to prevent injuries and reduce the chances of wasps returning to the same location.

This guide will help you understand why wasps choose underground locations and how you can effectively and safely remove these nests.

How to Identify Underground Wasp Nests

The first step in dealing with underground wasps is to confirm their presence. Unlike aerial nests that are easily spotted hanging from structures, underground nests require keen observation.

Look for wasps flying directly into the ground or disappearing into holes in the soil, particularly in sheltered spots or under bushes.

You might also notice an unusual amount of wasp activity along the ground with wasps entering and exiting from a hole.

Types of wasps that commonly build underground nests include yellow jackets and some species of hornets.

These wasps can be particularly territorial during the late summer when their colonies are at peak populations.

Identifying the type of wasp involved can help in choosing the best removal method, as some species are more aggressive than others.

Risks Associated with Underground Wasp Nests

Underground wasp nests pose several risks. Physically stumbling upon a nest can provoke wasps to attack and sting, a natural defense mechanism when they feel their home is threatened. Disturbing a nest during yard work is a common way many individuals discover these hidden dangers.

The health risks of wasp stings should not be underestimated. Stings are painful and can cause allergic reactions in some people, ranging from mild irritation to severe anaphylactic reactions that require immediate medical attention.

Multiple stings can be dangerous, particularly to children or pets who might unknowingly disturb a nest.

Preparation for Removal

Before attempting to remove an underground wasp nest, proper preparation is essential to ensure safety and increase the likelihood of a successful removal.

The best time for removal is either early morning or late evening when wasps are less active. This timing helps reduce the risk of stings as the cooler temperatures make wasps less likely to fly.

Safety should be your top priority. Gear up with protective clothing that covers the entire body. Wear long sleeves, pants, gloves, and a hat.

A face shield or bee veil can provide additional protection for your face and neck, which are particularly vulnerable areas. Ensure that all clothing gaps are sealed where wasps could enter.

Gathering the right tools is also crucial. Depending on the method you choose for removal, you may need items like insecticide designed for wasps, a large bucket, soil or sand, and water.

Keep all bystanders, especially children and pets, away from the area until the removal process is complete and the site is deemed safe.

DIY Removal Methods

Once you’re prepared, you can consider a few do-it-yourself methods to tackle the underground wasp nest. One of the most effective and environmentally friendly approaches involves using soapy water.

This method works because the soap clogs the wasps’ breathing pores, effectively suffocating them without the use of harsh chemicals.

Locate the Nest

Confirm the primary entrance of the nest during the day when the wasps are active. This is where you will target your treatment.

Prepare the Solution

Mix a generous amount of dish soap with water in a large bucket. You’ll need enough to completely flood the nest.

Apply at Night

Approach the nest at night, wearing your protective gear. Slowly pour the soapy water into the nest entrance, being careful to do it steadily to avoid splashing.

Cover and Seal

After pouring, immediately cover the entrance with a large bowl or a piece of thick cloth to prevent wasps from escaping and to ensure the mixture stays inside the nest.

Repeat this process over a few nights if necessary, as it may take multiple attempts to fully eradicate the colony.

Professional Removal Methods

If the wasp nest is particularly large or if you’re allergic to stings, it’s wise to skip DIY methods and call professional pest control.

Professionals have access to more effective tools and protective gear, ensuring the nest is handled safely and thoroughly.

They can also provide solutions for long-term prevention, reducing the likelihood of wasps returning to the area.

Post-Removal Procedures

After the nest has been removed, whether by DIY methods or a professional, certain post-removal steps are important to ensure your yard remains wasp-free.


Keep an eye on the former nest area for several days to ensure no new activity occurs. Sometimes, wasps attempt to rebuild or new wasps may try to establish a nest.


Safely clean the area with water and soap to remove any remaining pheromones or traces of the nest that might attract other wasps.


To prevent future nests, consider applying a preventative wasp repellent around the yard. Keep the yard clean from food scraps or sugary spills that could attract wasps.

Removing an underground wasp nest can be a challenging and risky endeavor, but with the right preparation, tools, and knowledge, it can be done safely and effectively.

Whether you choose to handle the situation yourself or call in professionals, the key is to act swiftly and cautiously to minimize the risk of stings and ensure a safe environment for everyone involved.
