Roly pollies, also known as pill bugs or woodlice, are small crustaceans commonly found in gardens. These creatures thrive in damp environments and primarily feed on decaying organic matter. While they contribute to decomposition, an overabundance can lead to damage of young plants and seedlings. Controlling their population is a common concern for gardeners seeking to protect their cultivated areas.
Managing excessive populations of these crustaceans offers benefits beyond simply reducing potential plant damage. It can contribute to a healthier overall garden ecosystem by preventing the disruption of beneficial insect populations that might compete for resources or be preyed upon. Historically, various methods have been employed to control rolly pollie populations, ranging from simple habitat modification to the application of organic pesticides.
Effective strategies for managing these creatures typically involve reducing moisture, eliminating their food sources, and, if necessary, employing targeted treatments. The subsequent sections will detail specific methods that can be implemented to achieve a balance and minimize the impact of rolly pollies on cultivated plants.
Strategies for Roly Pollie Population Management
The following strategies outline effective methods to reduce rolly pollie populations in gardens, focusing on habitat modification and targeted control measures.
Tip 1: Reduce Moisture: Roly pollies thrive in damp environments. Minimize standing water and improve drainage by amending soil with organic matter. Water plants in the morning to allow foliage to dry throughout the day.
Tip 2: Eliminate Food Sources: Remove decaying organic matter, such as fallen leaves, rotting wood, and compost piles, from around susceptible plants. This deprives rolly pollies of their primary food source.
Tip 3: Create Barriers: Place physical barriers around vulnerable plants. Copper tape or diatomaceous earth can deter rolly pollies from reaching seedlings and low-lying foliage.
Tip 4: Introduce Predators: Encourage natural predators such as spiders, ground beetles, and toads within the garden environment. These beneficial insects and amphibians will prey on rolly pollies.
Tip 5: Trap and Relocate: Utilize traps baited with potato slices or damp newspaper. Regularly check traps and relocate captured rolly pollies away from the garden area.
Tip 6: Apply Diatomaceous Earth (DE): Food grade diatomaceous earth is a natural desiccant. Lightly dust the soil around plants with DE to dehydrate and control rolly pollie populations. Reapply after rain.
Tip 7: Use Organic Insecticides (Judiciously): If other methods are insufficient, consider using organic insecticides specifically formulated for crustaceans. Pyrethrins and spinosad can be effective but should be used sparingly and according to label instructions to minimize impact on beneficial insects.
Implementing these strategies in combination offers the most effective and sustainable method for maintaining a balanced ecosystem and mitigating the impact of excessive rolly pollie populations on garden plants.
The next section provides a summary of the key considerations for ongoing rolly pollie population management.
1. Reduce moisture
Moisture control is a foundational strategy in managing rolly pollie populations in gardens. Their physiology dictates a dependence on humid environments for survival and reproduction. Reducing moisture levels directly impacts their habitat suitability, thereby limiting population growth.
- Impact on Roly Pollie Physiology
Roly pollies, being crustaceans, possess gills that require moisture for respiration. Dry conditions lead to dehydration and impede their ability to breathe. Therefore, reducing moisture levels creates an inhospitable environment that weakens and diminishes their numbers.
- Disruption of Breeding Cycles
Damp conditions are essential for successful reproduction. Roly pollies require moist soil to lay and incubate their eggs. By minimizing moisture, the reproductive cycle is disrupted, preventing population expansion. This aspect is crucial for long-term control.
- Habitat Modification for Reduced Survival
Areas with consistently high moisture levels, such as under rocks, mulch, or dense foliage, provide ideal refuge for rolly pollies. Removing these moisture-retaining elements reduces their hiding places and exposes them to predators and desiccation, directly affecting their survival rate.
- Prevention of Fungal and Algal Growth
Excessive moisture promotes the growth of fungi and algae, which can serve as a supplementary food source for rolly pollies. Controlling moisture limits this food availability, further restricting their population growth and compelling them to seek alternative, less-suitable habitats.
In summary, reducing moisture in the garden environment directly addresses the biological needs and preferred habitats of rolly pollies. This foundational strategy, when implemented effectively, creates a less hospitable environment, hindering their survival, reproduction, and ability to thrive, and it should be part of a multi-pronged approach of “how to get rid of rolly pollies in garden”.
2. Eliminate decaying matter
The removal of decaying organic matter is a fundamental aspect of population control. Roly pollies are detritivores, relying on decomposing plant material as a primary food source. Consequently, the presence of fallen leaves, rotting wood, and neglected compost provides a readily available food supply that sustains and encourages their proliferation. By actively eliminating these resources, the carrying capacity of the garden environment is reduced, directly impacting the ability of rolly pollies to maintain large populations. Neglecting this step undermines other control efforts, as a constant food supply allows the population to rebound quickly.
Practical application of this principle requires diligent garden maintenance. Fallen leaves should be raked and removed promptly, especially during autumn. Rotting wood should be replaced or eliminated entirely. Compost piles should be located away from cultivated areas and managed to ensure rapid decomposition, preventing rolly pollies from establishing within. Furthermore, avoiding the excessive use of mulch, which retains moisture and provides a food source as it breaks down, can also contribute to effective population control. Example: Many gardens use mulch around the base of plants to help retain soil and decrease the need to water; this, however, creates a breeding ground for rolly pollies, which would then in-turn harm the leav
es or stems of the plant. Consider using inorganic ground coverings like rocks or pebbles if you wish to keep them away.
The systematic removal of decaying matter presents challenges, particularly in larger gardens with abundant vegetation. Regular inspection and maintenance are necessary to ensure effective control. The benefits, however, are significant. Eliminating their food source weakens the existing population, reduces their reproductive rate, and enhances the effectiveness of other control methods. This proactive approach is essential for long-term population management and contributes significantly to the success of “how to get rid of rolly pollies in garden” without the direct use of toxic agents.
3. Physical barriers
The implementation of physical barriers represents a direct and often effective strategy in the overall effort. Roly pollies, lacking the ability to climb smooth vertical surfaces, are susceptible to containment. Barriers serve to physically impede their access to vulnerable plants and seedlings, directly reducing potential feeding damage. This tactic is particularly effective in protecting specific high-value plants or localized areas within the garden.
Examples of effective barriers include copper tape, which emits a slight electrical charge that deters rolly pollies, and rings of diatomaceous earth, a desiccant that dehydrates them upon contact. Plastic or metal edging, sunk slightly into the soil, can also provide a physical obstacle. The height and material of the barrier must be carefully considered to ensure that rolly pollies cannot circumvent it. Proper installation is essential; gaps or breaches in the barrier will negate its effectiveness. For example, a raised garden bed surrounded by smooth metal flashing effectively prevents rolly pollies from accessing the soil and plants within.
While physical barriers offer a targeted solution, they are most effective when integrated with other control methods. Addressing moisture levels and eliminating food sources in conjunction with barrier implementation creates a more comprehensive approach. The primary limitation of physical barriers is their localized effect; they protect specific areas but do not address the underlying population. Therefore, strategic placement and ongoing maintenance are crucial for maximizing their contribution to effective population control in the garden.
4. Natural predators
The introduction of, or support of, natural predators within a garden ecosystem presents a biologically sound approach to managing rolly pollie populations. This method leverages existing trophic relationships to regulate rolly pollie numbers, reducing reliance on direct intervention strategies.
- Amphibians and Roly Pollie Control
Amphibians, such as toads and frogs, are opportunistic feeders. Roly pollies, being slow-moving and readily available, constitute a portion of their diet. Encouraging amphibian presence, through provision of habitat (e.g., ponds, damp areas), contributes to natural rolly pollie suppression. The impact is localized but sustainable, particularly in gardens with suitable conditions.
- Insectivores: Ground Beetles and Spiders
Various insectivorous insects, notably ground beetles and spiders, prey on rolly pollies. Ground beetles, active at night, forage on the soil surface, directly encountering and consuming rolly pollies. Spiders, through web construction or active hunting, also capture rolly pollies. Supporting these beneficial insects, by minimizing pesticide use and providing shelter (e.g., leaf litter, undisturbed areas), augments rolly pollie control.
- Birds and Their Role
Certain bird species, particularly those that forage on the ground, will consume rolly pollies. Providing bird-friendly habitats, including access to water and nesting sites, indirectly supports rolly pollie population management. While birds are not specialized rolly pollie predators, they contribute to the overall reduction of their numbers, particularly in open garden areas.
- Nematodes and Biological Control
Certain species of nematodes are parasitic to insects and crustaceans, including rolly pollies. Application of commercially available nematode products can provide targeted biological control. These nematodes invade and kill rolly pollies, offering a more specific intervention compared to broad-spectrum insecticides. However, the effectiveness of nematode application depends on soil moisture and temperature conditions.
Harnessing natural predators presents a sustainable, ecologically sound strategy. While this approach may not eliminate rolly pollies entirely, it contributes to a balanced ecosystem, reducing their numbers to a level that minimizes plant damage. This approach provides a long-term solution when combined with other methods.
5. Trapping
Trapping represents a localized, non-chemical method for managing rolly pollie populations in gardens. Its relevance lies in its ability to physically remove individuals from the environment, directly reducing their numbers and mitigating potential damage to plants. This approach is particularly useful for targeting specific areas where rolly pollie activity is concentrated.
- Bait Selection and Trap Placement
Effective trapping relies on attracting rolly pollies to a designated location. Common baits include potato slices, melon rinds, and damp newspaper. These materials provide the moisture and decaying organic matter that attracts them. Trap placement is crucial; locating traps in areas of known rolly pollie activity, such as under rocks or near damp foliage, increases capture rates. For example, burying a container with small entry holes near a cluster of seedlings, baited with a potato, can effectively draw rolly pollies away from the vulnerable plants. These can then be relocated.
- Trap Types and Construction
Various trap designs can be employed, ranging from simple to more elaborate configurations. A basic trap involves placing a bait item under an overturned flowerpot or piece of cardboard. Roly pollies congregate underneath, seeking shelter and food. More elaborate traps involve burying containers with small entry holes, creating a one-way passage. The choice of trap depends on the scale of the infestation and the resources available. Regardless of the design, regular monitoring and emptying of the traps are essential for maintaining their effectiveness.
- Relocation and Population Impact
The primary benefit of trapping lies in the ability to physically remove rolly pollies from the garden. Relocating captured individuals to a more remote area, away from cultivated plants, prevents them from returning and causing further damage. The impact of trapping on the overall population depends on the intensity and duration of the trapping effort. Consistent trapping over time can significantly reduce local rolly pollie numbers, particularly when combined with other control methods.
- Limitations and Integration with Other Strategies
Trapping is not a standalone solution. It addresses the symptom (p
resence of rolly pollies) rather than the root cause (favorable environmental conditions). Trapping is most effective when integrated with habitat modification strategies, such as reducing moisture and removing decaying organic matter. Furthermore, trapping is labor-intensive and may not be feasible for large-scale infestations. Its primary value lies in its targeted approach, allowing for the removal of rolly pollies from specific areas of concern, contributing to the overall strategy for managing rolly pollie populations.
Trapping, while not a comprehensive solution, provides a valuable tool for localized population control. Its effectiveness is maximized when combined with other strategies that address the underlying factors contributing to rolly pollie proliferation, contributing to the effectiveness of the overall strategy for “how to get rid of rolly pollies in garden”.
6. Diatomaceous earth
Diatomaceous earth (DE) plays a significant role in managing rolly pollie populations within gardens. Its effectiveness stems from its composition: fossilized remains of diatoms, microscopic algae, which create a fine powder with abrasive and absorbent properties. These properties directly impact the exoskeleton of rolly pollies, leading to desiccation. When applied around susceptible plants, DE acts as a physical barrier and a lethal contact agent.
The efficacy of DE is contingent upon its application and environmental conditions. Food-grade DE is preferred for garden use due to its lower toxicity to mammals and beneficial insects, though caution should still be exercised. DE is most effective in dry conditions; rainfall or irrigation diminishes its abrasive properties and necessitates reapplication. It should be dusted lightly around the base of plants and in areas where rolly pollies congregate. Direct application onto foliage should be avoided, as it can impede plant respiration. For instance, vegetable gardens experiencing rolly pollie damage to seedlings benefit from a thin application of DE around the base of each plant, creating a protective zone. The desiccant action of DE disrupts the rolly pollie’s moisture balance, leading to death within days.
While DE provides a valuable tool for controlling rolly pollie populations, it should be viewed as part of an integrated pest management strategy. Habitat modification, such as reducing moisture and removing decaying organic matter, enhances the effectiveness of DE. Furthermore, the use of DE should be judicious to minimize its impact on beneficial insects and other soil organisms. Combining DE application with other control methods optimizes results and promotes a balanced garden ecosystem and in “how to get rid of rolly pollies in garden”, DE makes it effective.
7. Targeted treatments
Targeted treatments represent a strategic intervention in the overall objective. When preventative measures like habitat modification and natural predator encouragement prove insufficient, the implementation of targeted treatments becomes a necessary step. These treatments, typically involving the application of specific pesticides or biological control agents, aim to directly reduce rolly pollie populations in a localized manner while minimizing the impact on the broader garden ecosystem. The careful selection and application of these treatments are paramount, requiring an understanding of their mode of action and potential non-target effects. The direct effect is to reduce the population size in the short term which would help in getting rid of the rolly pollies in the long run with other prevention method.
The connection between targeted treatments and “how to get rid of rolly pollies in garden” is causal and conditional. In other words, Targeted treatments are used to manage the amount of rolly pollies in the garden. For example, an organic insecticide containing spinosad, applied directly to areas with high rolly pollie concentrations, reduces their numbers with limited impact on beneficial insects if used according to label instructions. Similarly, the introduction of specific nematode species that parasitize rolly pollies can provide biological control in a localized area. The long-term success of targeted treatments depends on addressing the underlying factors that contribute to rolly pollie proliferation. If environmental conditions remain favorable, re-infestation is likely. Therefore, targeted treatments should always be integrated with preventative measures for sustainable control. For example, if you were to spray a plant with insecticidal soap, make sure to address the area’s moist conditions, and reduce leaf buildup on the ground to prevent recurrence.
The practical significance of understanding the role of targeted treatments lies in achieving effective and sustainable rolly pollie management. Over-reliance on these treatments, without addressing underlying causes, can lead to resistance development and ecological disruption. Conversely, neglecting targeted treatments when preventative measures are insufficient can result in significant plant damage. A balanced approach, prioritizing preventative measures and reserving targeted treatments for specific situations, is crucial for minimizing the negative impacts of rolly pollies while preserving the health and biodiversity of the garden ecosystem. Without taking into account what targeted treatments does, preventing is harder to do.
