Mole Crickets in Lawn: What to Do – Effective Solutions for a Healthy Yard

Mole crickets can be a nuisance and cause damage to your lawn. These nocturnal insects are known for their tunneling activities, which can leave unsightly trails and harm the root systems of your grass. But don’t despair, as there are solutions available to help control mole cricket populations in your yard.

To determine whether mole crickets are present, try using a soapy water solution. By mixing 1.5 fluid ounces of liquid dish soap in 2 gallons of water and pouring it over 4 square feet of turf, you can flush these pests out of hiding University of Florida. Identifying the problem is the first step in taking control of your lawn health.

Effective mole cricket management can be achieved by using a combination of methods. Some options include timely insecticide applications, biological controls like nematodes, and altering your lawn care practices to make it less favorable for mole crickets to thrive NC State Extension Publications.

Understanding Mole Crickets

Types of Mole Crickets

There are several types of mole crickets that can cause damage to your lawn. The most common and damaging species are the tawny mole cricket (Neoscapteriscus vicinus), the southern mole cricket (Neoscapteriscus borellii), and the northern mole cricket (Neocurtilla hexadactyla).

• The tawny mole cricket is an introduced pest in the United States and has a significant impact on turfgrass.
• The southern mole cricket is also a non-native pest and can cause considerable damage.
• The northern mole cricket is native to the US and usually causes little to no damage to lawns.

Life Cycle of Mole Crickets

Mole crickets have a life cycle consisting of egg, nymph, and adult stages. For example:

1. Adult mole crickets lay eggs in their tunnels.
2. Eggs hatch into nymphs, which go through several molts before becoming adults.
3. Adult mole crickets emerge, mate, and lay eggs to continue the cycle.

• Southern mole crickets complete their life cycle in about one year.
• Northern and prairie mole crickets may take two to three years to mature.

Pros of Mole Crickets:

• They can help aerate the soil in lawns.

Cons of Mole Crickets:

• Damaging to turfgrass by tunneling and eating plant roots.
• Difficult to control due to their nocturnal behavior.

In conclusion, understanding mole crickets, their types, and life cycles can help you identify potential damage and decide on appropriate control measures for your lawn.

Recognizing Mole Cricket Damage

Signs of Damage

Mole cricket damage is fairly easy to recognize. Signs include:

• Disturbed soil
• Tunneling in the soil

• Dislodged seedlings or plants

Specific signs of mole cricket damage include a network of tunnels near the soil surface, which can be seen as raised ridges. The tunneling damages grass roots and causes dying grass patches in lawns¹.

Affected Grass Types

Mole crickets mainly affect warm-season grasses. Some examples are:

• Bermuda grass
• Bahiagrass

Warm-season grasses like Bermuda and Bahia are more susceptible to mole cricket damage because they thrive in the same warm, moist environments that mole crickets prefer².

Preventing and Controlling Mole Crickets

Monitoring and Detection

To effectively manage mole crickets, early detection is crucial. Monitor your lawn for signs of damage, such as raised tunnels or disturbed soil. You can use the soapy water drench method to flush out mole crickets: mix a few tablespoons of dish soap in a gallon of water and pour the solution over a small area of the lawn. If mole crickets are present, they will emerge to the surface within a few minutes (Clemson Information).

Non-Chemical Control Methods

Mole crickets can be managed using non-chemical methods:

• Introduce natural predators like birds and certain insects to the lawn
• Practice proper lawn care: mow regularly, water deeply but infrequently, and fertilize appropriately
• Use cultural controls: select mole cricket-resistant turfgrass species or varieties

Chemical Control Methods

When non-chemical methods are not enough, consider using chemical controls:

Pros

• Effective in reducing mole cricket populations
• Targeted application reduces damage to turfgrass

Cons

• May harm beneficial organisms
• Resistance may develop over time

Remember to always read and follow label instructions when using chemical treatments. Implement an integrated pest management plan that combines monitoring, non-chemical methods, and chemical control methods for best results.
