Does Soapy Water Kill Mole Crickets?

Mole crickets – just hearing the name might send shivers down the spine of an avid gardener. These burrowing insects can wreak havoc on lawns, turning a once-lush green space into a patchy, damaged area.

But before you grab the heavy-duty pesticides, have you ever considered a more natural solution, like soapy water? Let’s explore whether this simple mixture is an effective remedy against mole crickets.

What are Mole Crickets?

Mole crickets are not your typical backyard cricket. They have large, shovel-like forelimbs adapted for digging. They tunnel through the soil, and in doing so, they can damage plant roots and disrupt the surface of lawns and gardens.

These creatures are particularly troublesome in the southern parts of the United States but can be found in various regions worldwide.

The Soapy Water Solution

The idea of using soapy water against pests isn’t new. Many gardeners have been using diluted soap as a pesticide for years. It’s a natural, environmentally friendly, and inexpensive method. But how does it fare against mole crickets specifically?

How Does Soapy Water Work?

The science behind it is rather simple. Insects, including mole crickets, breathe through their exoskeletons. When they come in contact with soapy water, the soap can block these breathing channels, suffocating the insect.

Additionally, the soap breaks down their protective waxy layers, causing dehydration.

Application: A Step-by-Step Guide

  1. Mixing: Create a solution consisting of a few tablespoons of liquid soap (preferably biodegradable) for every gallon of water.
  2. Testing: Before you treat your entire garden or lawn, test a small patch to see how the grass and plants react to the soapy water.
  3. Even Distribution: Pour or spray the solution over areas where you suspect mole cricket activity, typically marked by raised, tunnel-like structures in the ground. Do this in the evening when mole crickets are most active.
  4. Observation: Within a few minutes, if mole crickets are present, they’ll come to the surface as the soapy water infiltrates their tunnels.
  5. Removal: Once they emerge, you can collect and dispose of them.
  6. Rinse: After about 30 minutes, rinse the area with clean water to prevent any potential soap damage to the grass or plants.

Effectiveness and Considerations

While many gardeners report success with this method, its effectiveness might vary based on several factors:

  1. Soap Type: Not all soaps are created equal. Harsher detergents can harm your lawn and plants, so it’s crucial to choose a mild, preferably organic, soap.
  2. Mole Cricket Life Stage: Younger mole crickets, known as nymphs, are more vulnerable than mature ones. Therefore, timing your treatment can play a role in its success.
  3. Frequency: While soapy water can be an effective solution, it might not provide long-term control if the mole cricket population is large. Multiple treatments might be necessary.

The Environmental Impact

One of the most significant advantages of using soapy water is its reduced environmental impact compared to chemical pesticides. Here’s why:

  1. Safety: Soapy water is safer for children and pets. Once rinsed off, the area becomes instantly usable.
  2. Earth-Friendly: Biodegradable soaps break down and don’t contaminate groundwater or harm beneficial insects and microbes in the soil.
  3. Cost-Effective: Soap and water are readily available and inexpensive, making this a cost-effective treatment method.

Alternatives and Complementary Methods

If you’re dealing with a substantial mole cricket infestation, consider integrating multiple control methods:

  1. Beneficial Predators: Introducing natural predators like nematodes can help reduce the mole cricket population.
  2. Lawn Maintenance: Regular mowing, watering in moderation, and proper fertilization can make your lawn less appealing to these pests.
  3. Physical Traps: Setting up light traps at night can attract and capture mole crickets, reducing their numbers.


Does soapy water kill mole crickets? The simple answer is yes, it can be an effective method when used correctly. While it may not replace all traditional pest control measures, it offers an eco-friendly, safe, and cost-effective solution for those looking to tackle their mole cricket problem head-on.

As with all gardening endeavors, patience, observation, and adaptability are key. Embrace the journey, and may your lawns be evergreen and mole cricket-free!
