Does Your Garden Suffer From Mole Crickets?

This guide provides an in-depth understanding of the impact of mole crickets on gardens and lawns. Signs of mole cricket activity include raised lumps in the lawn and dead or dying brown patches of grass. Mole crickets cause significant damage by tunneling under the soil, and left untreated, they can become destructive to the lawn.

Despite their annoying behavior, crickets can benefit the garden ecosystem by feeding on organic matter, weed seeds, and even clippings from lawn mowers. They play a crucial role in maintaining a healthy environment for plants. Invasive mole crickets are a serious plant pest for many Floridians, damaging turfgrass, pastures, forage crops, and other plants.

Mole crickets primarily feed underground on plant roots, particularly grasses, and may damage potato plants’ roots. They push soil and newly rooted seedlings upward, causing visible damage and dead patches throughout the turf. When present in large numbers, field crickets can chew on young plants. As mole crickets reach maturity from late August to October, they produce significant damage to lawns due to their tunneling.

Tawny and shortwinged mole crickets can be serious pests of vegetable crops at times due to their herbivorous feeding behavior. To address a mole cricket infestation and repair your lawn, it is essential to know the signs of mole crickets and when this damage will become apparent.

What Time Of Year Are Mole Crickets Most Active?

Mole crickets in Florida are active throughout the year, with peak damage occurring in spring (March to June) and fall (late August to early October) when they are predominantly in the adult stage. They have one generation annually, with eggs laid in April and May. During spring, most mole crickets are adults, causing significant tunneling and feeding damage, particularly when conditions are warm. Male mole crickets do not usually fly but are known to call at night to attract females for mating. Females take flight shortly after sunset, drawn to areas with active male calls.

Activity levels for mole crickets increase after rainfall or watering of lawns, and they are omnivorous, often damaging turf by consuming grass roots. Moles exhibit peak activity in early morning or at midnight, thriving in temperatures between 55 and 65 degrees Fahrenheit. During summer, moles may dig deeper into the soil to escape heat, reducing surface tunneling. Despite being active at any time, their movements also align with food search and tunnel establishment needs, leading to seasonal behavior patterns.

For effective control of mole crickets, it is best to treat in June and July, particularly when nymph populations rise and before visible damage occurs. Active mole crickets appear as temperatures warm from late March to April, and overwintered individuals become active in February to April. Control measures taken during early spring may mitigate tunneling damage, although they are most effective later in the season as egg hatching peaks. Overall, monitoring soil moisture helps in recognizing mole cricket activity levels, as they are notably more active during moist conditions.
