How To Get Rid Of Rolly Pollies In Garden Naturally: Easy Tips

Can you get rid of rolly pollies naturally? Yes, you absolutely can! This guide offers easy, natural ways to manage rolly pollies (also known as pill bugs or armadillo bugs) in your garden.

Rolly pollies, those tiny, segmented creatures that curl into a ball when disturbed, are common garden inhabitants. While they play a role in decomposition, an overpopulation can lead to them munching on your delicate seedlings and young plants. The good news is, you don’t need harsh chemicals to tackle this issue. This article will guide you through effective natural pest control for gardens, focusing on organic ways to deter rolly pollies and prevent sowbugs from becoming a nuisance. We’ll explore how to manage these terrestrial crustaceans safely and humanely, ensuring your garden thrives without these common garden bugs that eat plants becoming a major problem.

Why Do Rolly Pollies Appear in My Garden?

Grasping why rolly pollies are attracted to your garden is the first step in successful management. These fascinating creatures, scientifically known as Isopoda, are crustaceans, not insects. They thrive in moist, dark environments and are primarily detritivores, meaning they feed on decaying organic matter.

Key Factors Attracting Rolly Pollies:

• Moisture: Rolly pollies need moisture to survive. They respire through gill-like structures that must remain moist. Areas with consistent dampness, such as under mulch, fallen leaves, rocks, and in dense ground cover, are prime rolly polly habitats.
• Food Sources: Their diet consists mainly of decaying plant material, fungi, and dead insects. However, when their preferred food is scarce, or when populations are high, they can turn to tender, living plant tissues.
• Shelter: They seek protection from predators and drying out. Dark, humid spaces offer ideal shelter.
• Overpopulation: A healthy garden ecosystem usually keeps rolly polly populations in check. Factors that disrupt this balance, such as excessive moisture or a lack of natural predators, can lead to an increase in their numbers.

Identifying a Rolly Polly Problem

It’s important to distinguish between a healthy presence of rolly pollies and an infestation that requires intervention.

Signs of a Problem:

• Damage to Seedlings and Young Plants: Chewed leaves, stems, or roots on young, tender plants are a strong indicator of rolly pollies feeding on them. Look for small holes or ragged edges.
• Large Numbers: While a few rolly pollies are beneficial, vast numbers congregating on plants or in certain areas of your garden suggest an imbalance.
• Visible Damage on Mature Plants: While less common, mature plants with damaged leaves or fruits can also be a sign, especially during prolonged wet periods.

Natural Rolly Polly Control Strategies

Effective woodlice control and pill bug removal rely on altering their environment and encouraging natural solutions.

1. Moisture Management: The Cornerstone of Natural Pest Control

Since rolly pollies need moisture, controlling the dampness in your garden is paramount for organic ways to deter rolly pollies.

• Improve Drainage: Ensure your garden beds drain well. Amend heavy clay soils with compost to improve aeration and water flow.
• Water Wisely: Water your plants in the morning. This allows the soil surface and foliage to dry out before evening, reducing humidity and the appeal for rolly pollies. Avoid overwatering.
• Reduce Mulch Thickness: While mulch is beneficial, a thick layer can retain excessive moisture. Keep mulch a few inches away from the base of plants, especially seedlings. Consider using coarser mulches that drain better, like wood chips, rather than fine composted materials in very wet areas.
• Remove Debris: Clear away fallen leaves, dead plant matter, and other organic debris where rolly pollies love to hide. This removes their food source and shelter.

2. Creating Barriers and Traps

Physical methods can effectively reduce rolly polly populations.

• DIY Traps:

  • Citrus Rind Trap: Place grapefruit or orange rinds, cut side down, on the soil surface in areas with high rolly polly activity. Rolly pollies are attracted to the moist pulp and will gather underneath. Check the rinds daily and dispose of the collected rolly pollies away from your garden.
  • Board Trap: Place a damp piece of wood or a flattened cardboard box in affected areas overnight. Rolly pollies will congregate underneath seeking moisture and shelter. Remove and dispose of them in the morning.
  • Diatomaceous Earth (Food Grade): This is a natural powder made from fossilized aquatic organisms. It has sharp edges that dehydrate and kill insects and other arthropods. Sprinkle a thin layer around the base of vulnerable plants. Reapply after rain. Caution: While natural, it can harm beneficial insects as well, so use strategically.

• Copper Tape: Applying copper tape around raised beds or containers can create a barrier. When rolly pollies touch the copper, a mild electrical reaction deters them.

3. Encouraging Natural Predators

A balanced ecosystem will naturally control pest populations.

• Beneficial Insects for Gardens: Many beneficial insects prey on rolly pollies, including ground beetles, centipedes, and spiders. Avoid broad-spectrum insecticides that can kill these helpful creatures.
• Birds: Birds like robins and thrushes will eat rolly pollies. Providing bird baths and feeders can encourage them to visit your garden.
• Toads and Frogs: Amphibians are also natural predators. Creating a moist habitat for them, like a small pond or a consistently damp area, can attract them to your garden.

4. Companion Planting for Armadillo Bug Repellent

Certain plants can naturally deter rolly pollies.

• Garlic and Onions: The strong scent of garlic and onions is often disliked by many pests, including rolly pollies. Planting them near vulnerable crops can help.
• Rosemary and Mint: These aromatic herbs are known for their repellent qualities. Interplanting them can create a less hospitable environment for rolly pollies.

5. Biological Controls

These methods utilize natural organisms to manage pests.

• Nematodes: Specific species of beneficial nematodes (microscopic roundworms) can parasitize and kill rolly pollies. They are applied to the soil and are a safe, natural method.

Safe Ways to Manage Garden Pests: Beyond Rolly Pollies

The principles of natural pest control apply to many garden bugs that eat plants.

• Healthy Soil: Robust, healthy soil supports strong plants that are more resistant to pest damage. Incorporate compost and organic matter regularly.
• Crop Rotation: Rotating crops year after year helps prevent the buildup of pest populations specific to certain plant families.
• Hand-Picking: For smaller gardens, simply going out in the early morning or evening with a bucket and removing visible rolly pollies can be effective.

Addressing Sowbugs and Other Terrestrial Crustaceans

Sowbugs are closely related to rolly pollies and share similar habitat preferences. The strategies for woodlice control and pill bug removal are generally effective for preventing sowbugs as well. Eliminating terrestrial crustaceans like these often comes down to moisture and shelter management.
