Rolly pollies, also known as pill bugs or woodlice, are common garden inhabitants that can cause frustration among gardeners. While these small, armored creatures play a role in breaking down organic matter, their presence in large numbers can harm young plants and seedlings. If you’re wondering how to get rid of rolly pollies in the garden, this guide will walk you through proven strategies to control and prevent these critters from damaging your outdoor space.
In this article, you will discover why rolly pollies appear in your garden, the risks they pose, and practical, eco-friendly ways to manage their population. Whether you prefer natural remedies or targeted interventions, these expert-backed tips will help you reclaim your garden while maintaining ecological balance.
What Are Rolly Pollies and Why Do They Appear in Gardens?
Rolly pollies are terrestrial crustaceans, scientifically classified as woodlice. They thrive in moist, shaded environments rich in decaying plant matter. While they are beneficial decomposers in ecosystems, their feeding habits can turn problematic in gardens, especially when they start nibbling on tender seedlings and roots.
Common Signs of Rolly Pollie Infestation:
- Presence of small, grayish, segmented bugs curling into a ball when disturbed.
- Damaged seedlings with chewed leaves or stems.
- Damp, shaded soil areas with plenty of organic mulch or debris.
Why do they invade gardens?
Rolly pollies seek moisture and shelter. Gardens with excessive mulch, dense plant cover, or poor drainage create ideal habitats. Understanding these factors is key to controlling their population effectively.
How to Identify Rolly Pollies in Your Garden
Knowing what rolly pollies look like helps in early detection and timely control.
- Size: Usually 1/4 to 1/2 inch long.
- Shape: Oval, segmented body with seven pairs of legs.
- Color: Gray or brownish.
- Behavior: Curl into a tight ball when threatened.
Spotting these critters near seedlings and under debris indicates their presence. Regular garden inspections can prevent significant damage.
Effective Ways to Get Rid of Rolly Pollies in the Garden
1. Remove Excess Moisture and Shelter
Rolly pollies thrive in moist environments. Reducing moisture is the first step in discouraging them:
- Improve drainage by aerating soil and avoiding overwatering.
- Remove mulch buildup or layers that retain excessive moisture.
- Clear away decaying plant debris and wood piles where they hide.
- Trim dense groundcover to increase sunlight and airflow.
2. Use Natural Barriers and Repellents
Certain substances deter rolly pollies without harming your plants or beneficial insects:
- Diatomaceous earth sprinkled around plants creates abrasive surfaces that damage their exoskeleton.
- Copper tape or strips around garden beds act as effective physical barriers.
- Coffee grounds and crushed eggshells can discourage movement in treated areas.
- Essential oils like peppermint or neem oil sprayed lightly can repel these bugs.
3. Encourage Natural Predators
Introducing or attracting natural enemies helps maintain rolly pollie populations organically:
- Ground beetles, spiders, and birds feed on pill bugs.
- Installing bird feeders or insect hotels promotes a balanced garden ecosystem.
- Avoid broad-spectrum insecticides that kill helpful predators.
4. Use Targeted Organic Insecticides
When infestations are severe, organic pest control products can provide relief:
- Products containing pyrethrin or spinosad target soft-bodied insects safely.
- Apply treatments in the evening when rolly pollies are most active.
- Follow label instructions carefully to avoid plant damage.
5. Manual Removal and Trapping
Simple physical methods also help reduce populations:
- Turn over stones, pots, and debris regularly to collect and remove rolly pollies.
- Set up moist cardboard traps overnight and discard the captured bugs in the morning.
- Handpick visible rolly pollies during early morning or evening hours.
Prevention Tips to Keep Rolly Pollies Away Long-Term
- Maintain good garden hygiene by cleaning fallen leaves and dead plants.
- Avoid excessive mulch; use thinner layers of coarse organic materials.
- Water plants at the base rather than overhead to reduce soil moisture.
- Plant species that are less attractive to rolly pollies, such as lavender or rosemary.
- Regularly inspect your garden to catch early signs of infestation.
Real-World Example: Successful Rolly Pollie Control in a Home Garden
Jane, a home gardener in Oregon, noticed her seedlings wilting and discovered rolly pollies beneath her raised beds. She improved drainage by adding sand mixed with soil and removed thick layers of mulch. Jane also sprinkled diatomaceous earth around her vegetable plants and encouraged birds by setting up feeders nearby. Within weeks, the rolly pollie population decreased significantly, and her seedlings thrived without chemical pesticides.
FAQs About Rolly Pollies in the Garden
Q: Are rolly pollies harmful to plants?
A: They mainly feed on decaying matter but can damage seedlings and tender roots when populations spike.
Q: Can I use chemical pesticides on rolly pollies?
A: While possible, chemical pesticides may harm beneficial insects. Opt for organic options and natural control methods first.
Q: Do rolly pollies spread diseases to plants?
A: No, they do not transmit plant diseases but their feeding can weaken young plants.
Conclusion
Rolly pollies are a natural part of the garden ecosystem but can become pests when their numbers grow unchecked. By reducing moisture, removing shelter, using natural repellents, and encouraging predators, you can effectively control and prevent rolly pollie damage. Remember, integrated pest management that balances ecological health with plant protection yields the best long-term results.
