Roly polies, also known as pillbugs or sowbugs, are small, gray, crustacean-like insects that are commonly found in gardens and lawns. While they play a role in the ecosystem by breaking down decaying organic matter, these creatures can become a nuisance when their populations explode, leading to potential harm to your plants. If you’re struggling with these little critters in your garden, you are not alone. Fortunately, there are several effective methods to get rid of roly polies and keep your garden healthy and thriving. This comprehensive guide outlines practical tips and techniques to help you reclaim your garden from these resilient pests.
Understanding Roly Polies
Before diving into eradication methods, it’s helpful to understand the biology and behavior of roly polies. Here’s what you need to know:
What are Roly Polies?
Roly polies are not insects, but rather terrestrial crustaceans, belonging to the order Isopoda. They are often found in moist environments and typically come out to feed at night, munching on decaying organic matter, dead plants, and sometimes live plants, particularly seedlings and young shoots.
Why Are They in Your Garden?
Roly polies are attracted to gardens for several reasons:
– Moisture: They thrive in damp environments, so overwatered plants or accumulated debris can create ideal conditions for them.
– Food Supply: Decaying organic matter, like fallen leaves and mulch, provides them with a food source.
– Shelter: Roly polies seek refuge from predators and the sun under leaves, rocks, and other garden debris.
Signs of Roly Polies Infestation
One of the first steps in managing roly polies is recognizing the signs of their presence in your garden. Here are telltale indicators of an infestation:
Visible Damage to Plants
Look for signs of damage on your plants, particularly tender leaves and seedlings. Roly polies may cause:
– Chewed leaves with irregular holes
– Wilting or stunted growth in young plants
– Soil disturbances from digging
Presence of Adults and Nymphs
Finding clusters of adult roly polies, usually around moist areas or hidden under debris, can indicate a high population. Juvenile roly polies, or nymphs, may also be present.
Effective Methods to Get Rid of Roly Polies
Once you have identified an infestation, it’s time to take action. Here are effective strategies to control and eliminate roly polies from your garden:
1. Manual Removal
One of the simplest methods is to manually remove roly polies. While it can be time-consuming, it is eco-friendly and requires no special tools.
How to do it:
– Go out in the evening when roly polies are most active.
– Check under stones, flower pots, and moist leaves.
– Collect them in a container and relocate them away from your garden.
2. Create a Barrier
Establishing barriers can effectively deter roly polies from entering specific garden areas.
Suggested materials for barriers:
– Copper Tape: Place copper tape around raised beds. The copper creates an electrical charge that repels roly polies.
– Diatomaceous Earth: Sprinkle a thin layer around the base of plants. This natural powder is abrasive to their exoskeletons and will discourage them from crossing.
3. Reduce Moisture
Since moisture is a primary attractant, keeping your garden well-drained and reducing humidity can help minimize their populations.
Ways to reduce moisture:
– Water Wisely: Water early in the morning to allow moisture to evaporate before nightfall.
– Improve Drainage: Consider adding organic matter or sand to improve soil drainage if it tends to hold water.
4. Remove Debris and Hiding Places
Regularly cleaning up your garden can diminish shelter and food sources for roly polies.
Action Steps:
– Clear away fallen leaves, old mulch, and plant debris.
– Avoid leaving pots or stones that can trap moisture and act as shelters.
5. Use Traps
Trapping roly polies can be an effective way to monitor and reduce their numbers.
How to Make Simple Traps:
– Beer Traps: Bury a shallow dish in the soil and fill it with beer. Roly polies are attracted to the scent, fall in, and cannot escape.
– Eggshell Traps: Place crushed eggshells around your plants to deter them. The sharp edges can harm them, while also providing nutrients to the soil.
6. Introduce Natural Predators
Utilizing natural predators can be an effective biological control method.
Natural predators to consider:
– Nematodes: These microscopic worms can infest and kill roly polies.
– Toads and Birds: Encouraging these animals into your garden helps control roly polie populations naturally.
Additional Chemical Control Methods
If you find that cultural and manual methods are insufficient, you may consider using commercial insecticides designed for roly polies. However, it is crucial to use them judiciously and follow all safety instructions.
Choosing the Right Insecticide
When selecting an insecticide, look for products specifically labeled for use against roly polies and those that are safe for garden use. Always opt for targeted applications to minimize harm to beneficial insects and the environment.
Application Tips
- Apply insecticides during early morning or late afternoon to avoid harming pollinators.
- Follow the manufacturer’s instructions carefully for safe and effective use.
Prevention is Key
Once you have successfully reduced the roly polie population in your garden, it’s essential to implement preventative measures to avoid future infestations.
Best Practices
- Soil Health: Maintain healthy soil by regularly adding organic compost and ensuring good drainage.
- Regular Inspections: Make it a habit to inspect your garden regularly for signs of any pest activity.
- Diverse Planting: Grow a variety of plants to create a balanced ecosystem that is less appealing to roly polies.
Conclusion
Keeping your garden free from roly polies requires a multifaceted approach that combines manual methods, cultural practices, and, when necessary, chemical controls. By understanding their habits and implementing proactive measures, you can maintain a flourishing garden environment that is welcoming not only for your plants but also for beneficial wildlife.
Ultimately, regular monitoring and a healthy garden ecosystem will help ensure that your roly polie problems are kept in check, allowing you to enjoy the beauty and bounty of your garden without interference from these little invaders. With these strategies in place, you can be confident in your ability to protect your garden and foster a vibrant growing space for years to come.
What are Roly Polies and why are they in my garden?
Roly polies, also known as pillbugs or woodlice, are small, crustacean-like insects that commonly inhabit damp environments. They are often found in gardens, particularly in areas with decaying organic matter, as they feed on decomposing plant material. While they are generally harmless, their presence can become problematic when they start to feed on young plants and seedlings.
Their preference for moist environments means they thrive in the conditions created by mulch, compost, and damp soil. If your garden has a lot of organic matter or shade, it may be particularly attractive to these creatures. Understanding their habitat preferences can help you better manage their presence in your garden.
Are Roly Polies harmful to my plants?
Roly polies are not typically harmful to established plants; they mainly feed on dead organic matter. However, when it comes to seedlings or young plants, their feeding habits can cause considerable damage. They may chew on the tender roots and leaves, leading to stunted growth or even the death of the plant.
To mitigate their impact, it’s essential to monitor your plants closely, especially during their early growth stages. If you notice damage, it might indicate a larger population of roly polies that requires management strategies to protect your garden’s vitality.
What are some natural methods to control Roly Polies in my garden?
There are several natural methods to control roly polies in your garden. One effective strategy is to create barriers using diatomaceous earth or crushed eggshells around your plants.
