Grubs can wreak havoc on Lakewood Ranch lawns, feeding voraciously on grass roots and leaving behind weak, patchy areas. To effectively get rid of grubs, it’s crucial to understand their life cycle and the telltale signs of an infestation. These pesky pests, often the larval stage of beetles like Japanese beetles and Southern masked chafers, are most active during the fall when they feed extensively. But did you know that Florida’s warm climate can allow some grub species to produce more than one generation per year? This makes proactive management even more essential.
Grubs not only harm your lawn but also attract wildlife such as raccoons, moles, and armadillos, which can further damage your turf while digging for these creamy, brown-headed larvae. If left unchecked, a serious infestation—typically 10 or more grubs per square foot—can turn your lush green lawn into a patchy, lifeless mess.
In this guide, we’ll explore how to identify and get rid of grubs while sharing expert strategies to protect your Lakewood Ranch lawn from future infestations. From natural solutions to effective preventive measures, you’ll find everything you need to restore your lawn’s health and vibrancy. Let’s dive in!
Key Takeaways

By combining proper timing, effective treatments, and proactive lawn care, you can get rid of grubs and keep your lawn thriving in Southwest Florida.
Understanding Grubs: What They Are and How They Damage Your Lawn
Grubs, the larval stage of beetles such as Japanese beetles, June bugs, and other scarab species, are one of the most common culprits behind unhealthy lawns in Lakewood Ranch. These c-shaped insects are easy to identify by their soft, white or cream-colored bodies, brown heads, and visible legs clustered near their heads. Ranging in size from as small as 1/8 inch to nearly 2 inches, grubs may seem harmless, but their feeding habits tell a different story.
Where Grubs Live and What They Do
Grubs thrive underground, nestled in the soil where they feed on grassroots and other organic material. This subterranean lifestyle means the damage they cause often goes unnoticed until it’s severe. Weak or discolored patches of grass, sections that peel away like loose carpet, or an uptick in animals like raccoons and birds digging at your yard are common signs of a grub problem.
The Grub Life Cycle
To get rid of grubs effectively, you must understand their life cycle, which consists of four distinct stages:
- Egg Stage: Adult beetles lay their eggs in moist soil during late spring or early summer.
- Larval Stage: These eggs hatch into grubs that immediately start feeding on grassroots, causing significant damage during this phase.
- Pupal Stage: Grubs burrow deeper into the soil and enter a dormant state to prepare for their transformation into adults.
- Adult Stage: After pupation, they emerge as beetles, ready to mate and lay the next generation of eggs.
How Grubs Impact Your Lawn
Grubs damage lawns by feeding on roots, weakening the turf and leaving it vulnerable to drought and disease. Their presence also attracts wildlife like armadillos, moles, and birds, which dig up your yard searching for these juicy snacks. If left untreated, an infestation can turn your once-lush lawn into a patchy, brown mess.
Understanding these characteristics and behaviors is key to taking proactive steps to protect your Lakewood Ranch lawn from grub infestations. In the next section, we’ll dive into practical and effective strategies to get rid of grubs and restore your lawn to its former glory.
Common Grubs That Threaten Southwest Florida Lawns
In Southwest Florida, the term “white grubs” often refers to the larvae of various scarab beetle species, each with unique characteristics but all sharing a destructive appetite for grassroots. These pests are responsible for significant lawn damage, particularly in late summer and early fall, when their feeding activity peaks. Let’s take a closer look at the most common grub species wreaking havoc on Florida lawns.
Southern Masked Chafer: Identifying and Managing This Common Lawn Pest
The Southern Masked Chafer is a significant threat to lawns in Southwest Florida, particularly in areas like Lakewood Ranch. Both the adult beetles and their larvae—commonly known as white grubs—play a role in the pest’s lifecycle, but it’s the grubs that cause the most damage to turfgrass. Understanding their characteristics and lifecycle is crucial for effective lawn management and prevention.
Adult Beetles: The Masked Chafer’s Signature Look
Adult Southern Masked Chafers are relatively small, measuring about 1/2 inch (10-14 mm) long. Their appearance is distinctive:
- Coloration: Dull, dark yellow-ocher or brown bodies with a black head. A characteristic dark brownish-black band or “mask” covers their eyes.
- Hair: Sparse, very short hairs distinguish them from their northern relatives, though these are challenging to see without magnification.
Adults are active during late June and July, attracted to lights at night. While they do not feed on plants, their presence indicates the potential for grub infestations.
Larvae: The Destructive White Grubs
The Southern Masked Chafer larvae are the primary culprits behind lawn damage:
- Appearance: White or cream-colored, C-shaped bodies with brown heads and six jointed legs. They grow up to 1 inch in length.
- Behavior: Grubs feed on grassroots, causing visible lawn damage as they mature through their three instars (developmental stages).

Get StartedLife Cycle: Timing Is Key
The Southern Masked Chafer follows a predictable lifecycle that heavily influences when and how damage occurs:
- Egg Stage: Females lay eggs 2-5 inches deep in the soil, which hatch within 14-18 days, depending on soil temperature.
- Larval Stage: Grubs hatch in late July to early August and start feeding immediately. They are most destructive during the second and third instars in late summer and early fall.
- Pupal Stage: As temperatures cool, grubs burrow deeper to overwinter. In spring, they return to the root zone for brief feeding before pupating 3-6 inches below ground.
- Adult Stage: Adults emerge in summer to mate, completing the cycle.
Habitat and Damage
Southern Masked Chafer grubs target various turfgrasses, including Bermuda grass, St. Augustine grass, Kentucky bluegrass, and tall fescue. Their feeding activity leads to:
- Yellowing and Death of Turf: Grass wilts and dies, especially in late summer and fall, creating spongy areas that easily peel away from the soil due to root loss.
- Increased Wildlife Activity: Animals such as birds, raccoons, and skunks often dig up affected lawns to feed on the grubs.
What Can You Do?
Effectively managing Southern Masked Chafer grubs starts with timely intervention. In the next section, we’ll explore the most effective treatments and preventive measures to get rid of grubs and restore the health of your Lakewood Ranch lawn. Stay tuned for expert tips on reclaiming your turf!
How to Identify Japanese Beetles and Their Larvae in Southwest Florida
Japanese beetles and their larvae are notorious for the damage they inflict on lawns and gardens. Recognizing these pests and understanding their lifecycle is key to preventing and managing infestations in your Lakewood Ranch lawn. Here’s what you need to know about identifying these beetles and their grubs.
Adult Japanese Beetles: Distinctive Metallic Invaders
Adult Japanese beetles are easy to spot due to their striking appearance and feeding behavior:
- Size and Shape: Oval-shaped and approximately 1/3 to 1/2 inch (8-11 mm) long.
- Coloration: A metallic green body with bronze or coppery-brown wing covers that don’t completely shield the abdomen.
- White Hair Patches: Five distinctive white hair patches on each side of the abdomen and one pair on the last abdominal segment.
- Antennae: Clubbed at the ends and capable of fanning out.
- Behavior: Active from late June through August, adults feed on leaves and flowers, skeletonizing foliage and causing extensive damage. Attracted by feeding-induced odors, they can fly long distances to find suitable feeding grounds.
Japanese Beetle Larvae: The Destructive Grubs
The larval stage, or grubs, of Japanese beetles is the most damaging phase for lawns:
- Appearance: C-shaped, white to cream-colored bodies with a tan or brown head capsule.
- Size: Grow from 1/8 inch to nearly 1 inch long, depending on developmental stage.
- Legs: Well-developed, visible legs near the head.
- Unique Feature: A V-shaped pattern of hairs (known as the “rastral pattern”) on the underside of the abdomen, a distinguishing characteristic of Japanese beetle grubs.
- Behavior: Grubs live in the soil, feeding on grass roots in late summer and fall. They overwinter deeper in the soil, return to the root zone in spring, and pupate in late spring.
The Lifecycle of Japanese Beetles
Understanding their lifecycle is essential for effective management:
- Egg Stage: Females lay eggs in moist soil, 2-3 inches deep, in late summer. Eggs hatch within two weeks.
- Larval Stage: Grubs feed on grass roots from late summer through fall, overwinter deep in the soil, and resume feeding in spring before pupating.
- Pupal Stage: Grubs pupate in late spring, transforming into adults within a few weeks.
- Adult Stage: Adults emerge in late June or early July, feeding, mating, and laying eggs during the summer months.
How to Identify Japanese Beetle Grubs
To differentiate Japanese beetle grubs from other white grubs, examine the pattern of hairs on the underside of the abdomen. The unique V-shaped “rastral pattern” is a reliable identifier. For adults, their metallic green and coppery-brown coloration, along with the white hair patches, makes them unmistakable.
By recognizing these characteristics and understanding their lifecycle, you can take targeted steps to get rid of grubs and protect your lawn. In the next section, we’ll explore effective strategies for managing Japanese beetle grubs and minimizing their impact on your yard.
Identifying and Managing European Chafer Beetles and Their Larvae
The European Chafer beetle is a significant pest in Southwest Florida, known for the severe damage its larvae inflict on lawns. Both the adult beetles and their grubs possess distinct features that make identification and management possible. Understanding their lifecycle and behavior is key to protecting your turf from their destructive feeding habits.
Adult European Chafer Beetles: The Subtle Menace
Adult European Chafers are often mistaken for other beetles like May/June beetles, but they have unique characteristics:
- Size and Color: Approximately 13-14 mm (0.51-0.55 inches) long with a light reddish-brown or tawny-brown coloration.
- Distinctive Features: A narrow band of light-yellow hairs (setae) on the pronotum and similar hairs on the thorax underside. The tip of their abdomen protrudes beyond their wing covers, which have visible longitudinal grooves.
- Behavior: Emerging from the soil in late spring, adults mate in large swarms on shrubs or low trees. These nocturnal beetles are most active on warm, clear nights above 19°C (66°F).
While the adults do not feed on plants, their presence indicates potential lawn damage from their larvae.
European Chafer Larvae: The Turf Destroyers
The larvae, or grubs, of European Chafer beetles are the primary culprits behind turf damage:
- Appearance: White, C-shaped grubs with a tan or yellow-brown head capsule. They range in size from 0.5 to 2.5 cm (0.2 to 1 inch).
- Raster Pattern: Two distinct, nearly parallel rows of coarse hairs at the posterior end of the abdomen form a pattern resembling a slightly open zipper—an important distinguishing feature.
- Body Segments: The last two body segments are often grey, which helps differentiate them from other white grub species.

- Pupal Stage: Grubs pupate in early June, forming earthen cells deeper in the soil. The pre-pupal stage lasts 2-4 days, and the pupal stage lasts around 2 weeks.
- Adult Stage: Adults emerge from the ground in June to begin the cycle anew.
Damage and Impact
European Chafer grubs can cause extensive damage to lawns by feeding on turfgrass roots, resulting in:
- Turf Damage: Dead patches, spongy soil, and weakened grass that easily pulls away from the soil.
- Increased Wildlife Activity: Animals like crows, skunks, and raccoons may dig up the turf in search of grubs, compounding the damage.
How to Identify and Manage European Chafer Grubs
To distinguish European Chafer grubs from other white grubs, look for the distinctive raster pattern on their hind end and the grey coloration of their last two body segments. For adults, their lighter color and smaller size compared to May/June beetles are key identifiers.
With their lifecycle and behavior in mind, you can take timely action to manage and prevent grub infestations. In the next section, we’ll explore effective strategies to get rid of grubs and restore your Lakewood Ranch lawn’s health and vitality.
Identifying and Managing June Beetles (May Beetles) and Their Grubs
June Beetles, also called May Beetles, are a common sight in Southwest Florida during the late spring and early summer months. While the adults are harmlessly drawn to lights at night, their larvae—white grubs—can cause extensive damage to lawns and crops. Understanding their characteristics, lifecycle, and behavior is crucial for effective management.
Adult June Beetles: Recognizing the Nighttime Visitors
Adult June Beetles are robust, oval-shaped insects with distinctive features:
- Size and Color: Ranging from 0.5 to 1.0 inch (1.2 to 3.5 cm) long, they are typically brown, black, rusty, or dark chestnut in color, without spots or stripes.
- Physical Features: The underside of their body is hairy, and they have shiny elytra (wing covers) with jointed legs. Their clubbed antennae can fan out or remain pressed together.
- Behavior: Adults are nocturnal and strongly attracted to lights, often colliding with windows and screens. They feed on plant leaves, flowers, and occasionally tree sap or fruits.
While their nighttime presence might be a nuisance, adult beetles themselves don’t cause significant damage compared to their larvae.
June Beetle Larvae: The Underground Threat
The grubs of June Beetles are the primary source of turf and crop damage:
- Appearance: White, C-shaped grubs with reddish-brown or black heads and three pairs of jointed legs. They can grow up to 1.25 inches (3.2 cm) in length.
- Habitat and Feeding: Grubs live underground, feeding on plant roots, decaying organic matter, and grassroots, leading to visible damage in lawns and gardens.
Lifecycle of June Beetles
The lifecycle of June Beetles spans several stages, with the larvae remaining in the soil for years:
- Egg Stage: Females lay eggs 2-5 inches deep in the soil during late spring or early summer. Eggs hatch within two weeks.
- Larval Stage: Grubs feed on plant roots for 1-4 years, depending on the species, passing through three instars (growth stages). They burrow deeper in winter to overwinter and return to the root zone in spring.
- Pupal Stage: In late spring, grubs pupate 3-6 inches deep in the soil. This transformation stage lasts a few weeks, leading to the emergence of adult beetles.
- Adult Stage: Adults emerge in late May or early June, mate, and lay eggs to restart the cycle. During the day, they stay burrowed into the soil and emerge at night to feed and mate.
Damage and Impact
June Beetle grubs are among the most destructive turf pests in Southwest Florida:
- Turf and Crop Damage: Feeding on roots weakens grass, causing dead patches and spongy soil. Crops and garden plants may also be affected.
- Wildlife Activity: Grubs attract skunks, moles, and birds that dig into turf, compounding the damage.
Additional Notes on Identification
With over 400 species of May/June beetles in North America, distinguishing between them can be challenging. However, the damage caused by their larvae is consistent across species, making identification of the grubs and their impact more important than distinguishing between adult beetles.
Effective Control Measures
Management strategies include crop rotation, natural predators, and mechanical control methods like strategic plowing. In the next section, we’ll explore targeted ways to get rid of grubs and protect your Lakewood Ranch lawn from further damage. Stay tuned for expert tips and solutions.
How to Get Rid of Grubs in Southwest Florida: Effective Strategies for Healthy Lawns
Managing grubs in Southwest Florida requires a multi-faceted approach combining preventative treatments, curative methods, and organic solutions. By timing your efforts correctly and adopting cultural practices, you can protect your lawn from these destructive pests. Here’s a step-by-step guide to effectively get rid of grubs and restore your turf.
