Rolly pollies feed primarily on decomposing plant matter, though they occasionally nibble tender seedlings when organic material runs scarce. If you have ever wondered what do rolly pollies eat when they invade your garden or potted plants, the answer is simpler than you might think. These small crustaceans, also known as pill bugs or woodlice, are nature’s recyclers rather than destructive pests.
Understanding their diet helps you manage them effectively without harming your plants. You might be surprised to learn that these little armored creatures are actually more helpful than harmful in most garden settings.
What Do Rolly Pollies Eat
Rolly pollies are detritivores, which means they consume dead and decaying organic material. Their primary food sources include fallen leaves, rotting wood, and decomposing plant matter. They play a vital role in breaking down organic waste and returning nutrients to the soil.
These creatures have a surprisingly varied diet that changes based on what is available in their environment. They are not picky eaters, but they do have clear preferences when given a choice.
Decomposing Plant Matter
The bulk of a rolly polly’s diet consists of dead plant material. They prefer leaves that have already begun to break down rather than fresh, crisp foliage. This preference makes them excellent composters in your garden.
- Fallen leaves and leaf litter
- Decaying grass clippings
- Rotting bark and wood chips
- Dead roots and stems
- Wilted flowers and spent vegetable plants
They also consume animal waste and the remains of dead insects when available. This scavenging behavior helps keep your garden clean and free of debris.
Living Plants And Seedlings
While rolly pollies prefer dead material, they will eat living plants under certain conditions. This usually happens when their preferred food sources are scarce or when populations become very large. Young seedlings with tender stems and leaves are most vulnerable.
You might notice damage to strawberries resting on damp soil or low-growing vegetables. They also eat young roots and can occasionally damage germinating seeds. However, this behavior is more opportunistic than intentional.
Fruits And Vegetables
Rolly pollies are attracted to soft, decaying fruits and vegetables. They will happily consume overripe tomatoes, fallen apples, and mushy squash. This makes them valuable cleanup crew members in vegetable gardens.
They are particularly fond of:
- Overripe strawberries and melons
- Soft vegetables like zucchini and cucumber
- Fallen citrus fruits
- Potatoes and carrots that are already damaged
What Do Rolly Pollies Eat In Different Environments
Their diet shifts depending on where they live. Indoor potted plants present different food options than outdoor garden beds. Understanding these differences helps you protect your plants effectively.
In The Garden
Outdoor rolly pollies have access to abundant organic material. They thrive in mulched beds, compost piles, and areas with heavy leaf litter. Their feeding activity improves soil structure and nutrient availability.
In garden settings, they consume:
- Mulch and wood chips
- Composted manure
- Dead flowers and vegetable debris
- Fallen fruit and vegetable scraps
In Potted Plants
Indoor rolly pollies have fewer food options. They will eat the organic matter in potting soil, including peat moss and composted bark. They may also feed on dead roots or damaged plant tissue.
When food runs low, they will start nibbling on healthy roots and young shoots. This is when they become problematic for houseplant owners. Regular soil checks help you catch infestations early.
In Compost Bins
Compost bins are rolly polly paradise. They accelerate decomposition and help break down kitchen scraps. They consume fruit peels, vegetable trimmings, coffee grounds, and crushed eggshells.
These creatures work alongside worms and bacteria to speed up the composting process. Their presence indicates a healthy, balanced compost system.
How To Manage Rolly Polly Feeding Habits
You can control rolly polly populations by managing their food sources. Removing excess organic debris reduces their numbers naturally. Creating barriers around vulnerable plants also helps protect your garden.
Reduce Their Food Supply
Clear away fallen leaves, rotting wood, and debris piles where they hide. Keep mulch layers thin and avoid overwatering, as they prefer damp environments. This simple approach reduces their population without chemicals.
Regular garden cleanup is the most effective prevention method. Remove overripe fruits and vegetables promptly. Keep compost bins covered and positioned away from garden beds.
Protect Vulnerable Plants
Create physical barriers around young seedlings and tender plants. Use diatomaceous earth, copper tape, or cardboard collars around stems. These barriers prevent rolly pollies from reaching their preferred food sources.
Water plants in the morning so soil dries by evening. Rolly pollies are nocturnal and prefer moist nighttime conditions. Dryer conditions discourage them from feeding on your plants.
Natural Predators
Encourage natural predators to visit your garden. Birds, toads, frogs, and ground beetles all eat rolly pollies. Creating habitat for these animals helps control populations naturally.
You can also manually remove rolly pollies during evening hours when they are most active. Simply pick them up and relocate them to your compost pile where they can do useful work.
Are Rolly Pollies Harmful Or Helpful
Rolly pollies are overwhelmingly beneficial to garden health. They break down organic matter, cycle nutrients, and improve soil structure. Their feeding activity creates rich, fertile soil that supports healthy plant growth.
Problems only arise when populations explode or when food sources become scarce. In normal conditions, they cause minimal damage and provide significant ecological benefits. They are also harmless to humans and pets.
Signs Of Rolly Polly Damage
Damage from rolly pollies appears as irregular holes in leaves, especially on seedlings. They eat soft tissue rather than veins, creating a distinctive pattern. You may also notice damage on fruits resting on damp soil.
Check for damage at night when they are most active. Look under mulch, rocks, and plant debris for large populations. Early detection prevents serious damage to your garden.
When To Take Action
Take action only when you notice significant damage to young plants. Small populations are beneficial and should be left alone. Large infestations may require intervention to protect your garden.
Start with cultural controls like removing debris and reducing moisture. Only consider chemical options as a last resort. Most gardens never need intervention because rolly pollies stay in balance naturally.
Frequently Asked Questions
Do Rolly Pollies Eat Living Plants?
Yes, but only when their preferred food sources are unavailable. They typically eat dead plant matter and only turn to living plants during scarcity. Tender seedlings and soft fruits are most at risk.
What Attracts Rolly Pollies To My Garden?
Moisture and organic debris attract them. They seek out damp, dark places with abundant food. Mulch, leaf litter, and compost piles are their favorite habitats.
Are Rolly Pollies Good For Compost?
They are excellent composters. They break down organic matter and speed up decomposition. Their presence in compost bins indicates a healthy, active system.
How Do I Get Rid Of Rolly Pollies Naturally?
Remove their food sources and hiding places. Clear away debris, reduce moisture, and create barriers around plants. Encourage natural predators like birds and toads.
Can Rolly Pollies Damage My Houseplants?
They can damage houseplants when food runs scarce. They may eat roots and young shoots. Keep potted plants clean and remove any dead material to discourage them.
Rolly pollies are fascinating creatures that play an important role in your garden ecosystem. Understanding what they eat helps you appreciate their value while protecting your plants. Their feeding habits are mostly beneficial, and they rarely cause serious problems when populations remain balanced.
By managing moisture and organic debris, you can enjoy the benefits of these natural recyclers without worrying about damage. They are allies in your gardening efforts, not enemies. Give them a place to work, and they will reward you with healthier soil and a more productive garden.
Remember that these little armored creatures have been around for millions of years. They know their job well. Let them do it, and you will see the difference in your garden’s health and vitality.
