If you’re trying to get rid of pillbugs in your Lakewood Ranch garden, you’re likely noticing these tiny, round creatures congregating in damp areas like under rocks, mulch, or decaying leaves. While pillbugs (often called “rollie-pollies”) might look harmless, their presence in large numbers can become a nuisance, especially when they start feeding on tender plants or vegetables.
Interestingly, pillbugs aren’t actually bugs at all—they’re crustaceans, closely related to crabs and shrimp. They play an important role in the ecosystem by helping to decompose organic matter and even detoxifying heavy metals from the soil. However, when their population grows too large, they can start feeding on young plants, causing damage to your garden. These nocturnal creatures are well-adapted to life on land, breathing through gills and rolling into a ball (a behavior known as conglobation) to protect themselves from predators.

In this post, we’ll explore practical ways to manage and get rid of pillbugs while maintaining the health of your Lakewood Ranch garden. From preventative strategies to practical steps, we’ll guide you through how to keep these decomposers in check. Whether you’re curious about their habits or just looking for a solution, we’ve got the answers you need to tackle your pillbug problem and protect your outdoor space.

Pillbugs – Key Characteristics
Pillbugs, commonly known as roly-polies, are small, land-dwelling crustaceans from the family Armadillidiidae. While they may look like insects, they are actually more closely related to aquatic crustaceans such as shrimp and crabs. These fascinating creatures have a unique ability to roll into a tight ball when threatened, much like their namesake, the armadillo. This defense mechanism, known as conglobation, helps them avoid predators.
Pillbug Identification Guide

Identification Features
Color: Typically dark gray to black, though some may appear brownish.
Size: They generally measure between ¼ inch to ¾ inch (approximately 6 to 19 mm) in length.
Body Structure: Pillbugs have an oval-shaped body that is longer than it is wide. Their bodies are made up of seven overlapping plates, giving them a segmented appearance. They possess two pairs of antennae and seven pairs of legs (14 legs total).
Shape: When threatened, pillbugs can roll into a tight ball, which is a key feature that distinguishes them from other similar creatures like sowbugs, which cannot roll up.
Habitat: Pillbugs prefer moist environments and are commonly found under rocks, logs, leaf litter, and in gardens or compost piles.
Behavior
Nocturnal Activity: Pillbugs are primarily active at night and tend to hide during the day to retain moisture.
Diet: They are scavengers that feed on decaying plant material, fungi, and occasionally tender plant parts.
Life Cycle
Pillbugs carry their eggs in a brood pouch under their bodies until they hatch. The young emerge as miniature versions of adults.
Conclusion
Pillbugs do not bite or sting. They play an essential role in the ecosystem by helping decompose organic matter. If you encounter them indoors, it’s usually due to moisture issues or access points that need sealing.
- Physical Characteristics: Pillbugs are easily recognizable by their oval, segmented bodies, which are typically slate-gray and measure about 1/4 to 5/8 inches in length. Their bodies are protected by overlapping plates that allow them to roll up, distinguishing them from their close relatives, sowbugs, which do not have this ability. They possess seven pairs of legs, giving them a total of 14 legs, and two pairs of antennae, although the second pair is often hidden from view. These features contribute to their agility in navigating moist environments.
- Habitat and Distribution: Pillbugs thrive in moist, humid environments, which is why you’ll often find them hiding under rocks, logs, and leaf litter, where decaying organic matter is abundant. Originally native to the Mediterranean region, they have since spread across the globe, adapting to various climates, including temperate forests, grasslands, and even some desert areas. In places like Lakewood Ranch, Florida, where the climate is warm and humid, pillbugs can be found in gardens and damp areas of the landscape.
- Behavior and Diet: These little crustaceans are detritivores, which means they feed on decaying plant material, helping to break it down and recycle nutrients back into the soil. This makes them important contributors to soil health, as they aid in the decomposition process. However, their preference for dark, damp places means they are most active at night, when the conditions are ideal for foraging. During the day, they avoid drying out by hiding in moist areas.
- Reproduction and Lifespan: Female pillbugs carry their eggs in a brood pouch located on the underside of their bodies, much like other crustaceans. After an incubation period of 3 to 7 weeks, the eggs hatch, and the young remain in the pouch for an additional 6 to 7 weeks. Pillbugs typically live for about two years, but under favorable conditions, they can live even longer.
- Ecological Role: In addition to helping maintain soil health, pillbugs play a crucial role in breaking down organic material, which improves soil structure and stimulates microbial activity. They also help aerate the soil, ensuring that plants have access to essential nutrients and oxygen. Their role as natural recyclers makes them valuable contributors to garden ecosystems, despite sometimes being viewed as pests.
- Interaction with Humans: Pillbugs can become a nuisance if their populations grow too large, especially when they begin to venture indoors. They do not bite or sting, but their presence in homes or greenhouses can be unwelcome. Occasionally, pillbugs may nibble on tender seedlings, but they are not typically destructive to healthy plants.
Overall, pillbugs are beneficial creatures that contribute to the balance of natural ecosystems by breaking down organic matter and improving soil quality. However, if their numbers become overwhelming in your Lakewood Ranch garden, it may be time to explore management strategies to keep them in check.
How to Get Rid of Pillbugs – A Comprehensive Guide
