Do Crickets Eat Plants?
Yes — crickets do eat plants, and in large numbers they can cause noticeable damage to gardens, lawns, and crops. However, the scale of damage depends heavily on cricket species, population size, and the time of year. Most backyard cricket encounters cause minor, cosmetic damage rather than the widespread destruction sometimes feared by gardeners.
Which Parts of Plants Do Crickets Eat?
Crickets are not selective feeders when it comes to plant material. They will consume almost any accessible part of a plant, including:
- Young seedlings — particularly vulnerable as they lack the tough structure of mature plants
- Leaves — crickets chew irregular holes or eat from the edges inward
- Stems — can be girdled (eaten around the circumference) near the soil line
- Flowers and petals — especially attractive to crickets due to sugar content
- Seeds — a high-energy food source, especially in autumn
- Fruits — soft, ripe fruits near ground level can be targeted
- Roots — underground feeding on small roots and root hairs
Which Plants Are Most at Risk?
Crickets show a preference for tender, moisture-rich vegetation. Plants most commonly reported as targets include:
| Plant Type | Examples | Level of Risk |
|---|---|---|
| Vegetable seedlings | Tomatoes, peppers, beans, lettuce | High |
| Cereals & grains | Corn, wheat, alfalfa | High (especially field crickets) |
| Ornamental flowers | Marigolds, petunias, pansies | Moderate |
| Lawn grass | Bermuda grass, fescues | Moderate (especially mole cricket species) |
| Woody plants & shrubs | Most established shrubs | Low |
| Mature fruit trees | Apple, pear | Low |
Field Crickets vs. Mole Crickets: A Key Distinction
Not all crickets cause the same kind of garden damage:
Field Crickets (Gryllus species)
These are the common black or brown crickets most people recognize. They feed primarily above ground on plant matter, seeds, and occasional insects. Damage tends to be localized and most noticeable on young seedlings and low-growing plants.
Mole Crickets (Gryllotalpa species)
Mole crickets are the more destructive species for lawns and turf. They burrow through the soil, severing grass roots and creating tunnels that dry out the soil. Mole cricket damage appears as brown, spongy patches on lawns, often in late summer and autumn.
How Much Damage Can Crickets Actually Cause?
In most home gardens, a normal cricket population causes minor and tolerable damage. The situation becomes problematic during population outbreaks — which can occur after unusually warm, dry summers — when hundreds or thousands of crickets may move through an area. Agricultural areas and turf farms are more susceptible to economically significant damage.
Managing Crickets in the Garden
If cricket numbers are causing concern, consider these management strategies:
- Reduce attractants — keep gardens free of debris, dense mulch, and tall weeds where crickets shelter
- Protect seedlings — use row covers or cloches to shield vulnerable young plants
- Natural predators — encourage birds, frogs, lizards, and spiders in the garden
- Diatomaceous earth — a non-toxic barrier that deters crawling insects
- Neem oil sprays — a natural deterrent applied to plant surfaces
- Sticky traps or jar traps — useful for monitoring cricket numbers
Crickets as Part of the Garden Ecosystem
It's worth noting that crickets also play a beneficial role in the garden. They help break down organic matter, aerate soil with their burrowing, and serve as an important food source for garden wildlife. Before treating crickets purely as pests, consider whether the damage level genuinely warrants intervention — in many cases, a healthy garden can absorb a natural cricket population without significant harm.
