Shortwinged Mole Crickets: Identification, Prevention, and Control

Identification and Biology of Shortwinged Mole Crickets

Physical Characteristics

• Size: Adults typically measure 1 to 1.5 inches in length.
• Color: They have a light brown to grayish-brown coloration, which helps them blend in with soil.
• Wings: As their name suggests, they have short wings that cover only about half of their abdomen.
• Forelegs: Their most distinctive feature is their powerful, shovel-like forelegs, adapted for digging.
• Antennae: They possess long, slender antennae that aid in sensing their environment.

Life Cycle

Understanding the life cycle of shortwinged mole crickets is crucial for effective pest management:

• Eggs: Female mole crickets lay eggs in underground chambers. Each female can lay up to 50 eggs at a time.
• Nymphs: After hatching, nymphs resemble small adults but lack wings. They go through several molts as they grow.
• Adults: Mature mole crickets emerge after about two months, ready to mate and continue the cycle.

The entire life cycle from egg to adult typically takes about a year, with peak activity occurring in spring and fall.

Habitat and Behavior

Shortwinged mole crickets are well-adapted to their subterranean lifestyle:

• Preferred Soil: They thrive in sandy or loose soils, which are easier to tunnel through.
• Tunneling: These insects create extensive tunnel systems just below the soil surface.
• Feeding Habits: Mole crickets are omnivorous, feeding on plant roots, insects, and organic matter in the soil.
• Activity Patterns: They are most active at night, often coming to the surface to feed or mate.

The Impact of Shortwinged Mole Crickets on Lawns and Gardens

Lawn Damage

The primary concern with shortwinged mole crickets is the damage they cause to lawns:

• Root Feeding: They feed on grass roots, weakening the plants and making them more susceptible to drought and disease.
• Surface Tunneling: Their tunneling activity near the soil surface can dislodge grass plants and create uneven, spongy areas in the lawn.
• Soil Disruption: Extensive tunneling can lead to soil drying and reduced water retention, further stressing the grass.

Garden Impact

While lawns are their primary target, shortwinged mole crickets can also affect garden plants:

• Vegetable Gardens: They may feed on the roots of young vegetable plants, stunting growth or killing seedlings.
• Flower Beds: Ornamental plants can suffer from root damage and soil disturbance.
• Soil Structure: Their tunneling can disrupt soil structure, affecting plant health and water distribution.

Prevention Tips: Keeping Shortwinged Mole Crickets at Bay

Lawn Maintenance Practices

Proper lawn care can make your yard less attractive to mole crickets:

• Mowing Height: Maintain your grass at the recommended height for your specific grass type. Taller grass is generally more resistant to mole cricket damage.
• Watering: Water deeply but infrequently to encourage deep root growth, making the grass more resilient to surface-level damage.
• Thatch Management: Remove excess thatch, as it can provide shelter for mole crickets and make detection more difficult.
• Soil Aeration: Regular aeration can improve soil structure and reduce compaction, making it less hospitable for mole crickets.

Natural Predators

Encouraging natural predators can help keep mole cricket populations in check:

• Birds: Many bird species, including robins and mockingbirds, feed on mole crickets. Consider installing bird feeders or baths to attract them to your yard.
• Beneficial Nematodes: These microscopic worms can parasitize mole crickets and other soil-dwelling pests. They're safe for humans and pets and can be applied as a soil drench.
• Toads and Frogs: These amphibians are natural predators of mole crickets. Creating a small pond or damp area in your yard can attract them.

Monitoring and Early Detection

Regular monitoring is key to catching a mole cricket problem before it becomes severe:

• Soap Flush Test: Mix 1-2 tablespoons of liquid dish soap with a gallon of water and pour it over a 2-square-foot area of your lawn. If mole crickets are present, they'll surface within a few minutes.
• Night Inspections: Use a flashlight to inspect your lawn at night when mole crickets are most active on the surface.
• Look for Signs: Be alert for raised tunnels in your lawn, especially in sandy areas, or small mounds of soil that resemble miniature mole hills.

Cultural Control Methods

Some cultural practices can help reduce the attractiveness of your yard to mole crickets:

• Reduce Nighttime Lighting: Mole crickets are attracted to lights, so minimizing outdoor lighting can make your property less appealing to them.
• Remove Debris: Keep your yard free of piles of leaves, grass clippings, or wood, which can provide shelter for mole crickets.
• Choose Resistant Grass Species: Some grass types, like Bermuda grass and St. Augustine grass, are more resistant to mole cricket damage. Consider these when planting or reseeding your lawn.

Treatment Methods: When to Call a Professional

Signs of Severe Infestation

While prevention is ideal, sometimes professional intervention is necessary to control a mole cricket infestation. Here are some signs that it's time to call in a licensed exterminator:

• Extensive Lawn Damage: If you notice large areas of your lawn turning brown or feeling spongy underfoot, it may indicate a severe mole cricket problem.
• Visible Surface Activity: An abundance of raised tunnels or small mounds across your lawn suggests a significant population.
• Failed DIY Attempts: If you've tried home remedies or over-the-counter treatments without success, it's time for professional help.
• Recurring Problems: If you've dealt with mole crickets in the past and they keep coming back, a professional can provide more lasting solutions.

Mole Cricket Behavior and Risks

Swarming Behavior

While shortwinged mole crickets don't swarm in the traditional sense, they do exhibit some group behaviors:

• Mating Flights: During mating season, usually in spring, adult mole crickets may engage in short flights to find mates.
• Population Surges: Under favorable conditions, mole cricket populations can increase rapidly, leading to sudden, widespread lawn damage.

Nesting Habits

Mole crickets create complex tunnel systems that serve multiple purposes:

• Protection: Tunnels provide shelter from predators and harsh weather conditions.
• Feeding: They feed on roots and organic matter encountered while tunneling.
• Reproduction: Females lay eggs in specially constructed chambers within the tunnel system.

Food-Seeking Behavior

Mole crickets are opportunistic feeders:

• Plant Material: They primarily feed on grass roots and shoots, but will also consume other plant matter.
• Insects: Mole crickets are known to eat other insects and their larvae found in the soil.
• Organic Matter: They'll consume decaying plant material and other organic matter in the soil.

Potential Risks and Damage

While mole crickets don't pose direct health risks to humans or pets, they can cause significant damage to lawns and landscapes:

• Economic Impact: Severe infestations can lead to costly lawn repairs or replacements.
• Aesthetic Damage: Mole cricket activity can create unsightly brown patches and uneven surfaces in lawns.
• Soil Erosion: Their tunneling can lead to increased soil erosion, especially on slopes or in areas with heavy rainfall.
• Secondary Pest Problems: Damaged lawns may become more susceptible to weed invasions and other pest issues.
