Dealing with pesky two-lined spittlebugs in your garden can be a frustrating task. These small, wedge-shaped insects with distinct red eyes and legs are known scientifically as Prosapia bicincta. They feed on a variety of plants, using their mouthparts to pierce stems or leaves and extract the juices within. Some of their favorite targets include holly bushes and centipedegrass, potentially causing damage to your plants and lawn.
In order to effectively get rid of two-lined spittlebugs, understanding their lifecycle and habits is essential. The nymphs, or immature spittlebugs, are often found in warm-season turfgrasses but can also wreak havoc on cool-season grasses. They produce a spittle-like foam to protect their tender bodies from predators and dry conditions. Adult spittlebugs, on the other hand, typically feed on various ornamentals in the garden.
Armed with the right knowledge and strategies, you can successfully tackle these bothersome pests and protect your plants from potential damage. In this article, we will discuss various methods, tools, and tips to help you effectively eliminate two-lined spittlebugs from your garden and lawn.
Understanding the Two-Lined Spittlebug
Life Cycle
The life cycle of the two-lined spittlebug includes:
- Egg
- Nymph
- Adult
They complete their life cycle within one year1.
Physical Characteristics
Two-lined spittlebugs are identifiable by their:
- Wedge-shaped bodies
- Dark brown to black color
- Distinct red eyes
- Red or orange lines across wings2
Additionally, their size is around 0.38 inches long3.
Feeding Habits
The two-lined spittlebug isn’t picky when it comes to feeding, but some preferences include:
They pierce plant stems or leaves and suck out juices, causing damage8.
Comparison of Two-Lined Spittlebug Characteristics:
| Characteristic | Description |
|---|---|
| Life Cycle | Complete within one year9 |
| Color | Dark brown to black10 |
| Size | 0.38 inches long11 |
| Feeding Preferences | Turfgrasses, holly bushes, centipedegrass12 |
Identifying Two-Lined Spittlebug Damage
Signs of Infestation
Two-lined spittlebugs are known for leaving behind a frothy, white foam on grass blades and plant stems. This foam is created by the nymphs to protect themselves from predators and dehydration. To identify a spittlebug infestation, look for:
- Small, white, frothy masses on your lawn and plants
- Yellowing and browning of grass blades
- The presence of dark brown, wedge-shaped adult spittlebugs with distinct red eyes and legs
If you notice these signs, you may be dealing with a two-lined spittlebug infestation. Keep your lawn well-maintained, mow regularly, and remove excess thatch and debris to help minimize the risk of infestation.
Affected Plants
Two-lined spittlebugs can damage various types of plants, both turfgrass, and ornamentals. Some of the most commonly affected plants are:
- Centipedegrass
- St. Augustinegrass
- Zoysiagrass
- Bermudagrass
- Asters
Other susceptible plants include hollies, morning glories, junipers, and pine trees. Maintaining the health of these host plants is crucial for the prevention of spittlebug infestations. Proper watering, mowing, and removal of debris can contribute to a healthier lawn and landscape, making it more resistant to these pests.
You can also consider using organic methods, like introducing beneficial insects (e.g. ladybugs) to help control the spittlebug population. Keep in mind that the main goal is to minimize the harm caused by the spittlebugs without harming your lawn’s ecosystem.
Preventing and Controlling Spittlebug Infestations
Cultural Practices
To prevent spittlebug infestations, focus on maintaining a healthy turf:
- Avoid thatch buildup by mowing and irrigating the grass regularly
- Reduce humidity and hiding spots by removing garden debris and weeds
- Monitor temperatures, as spittlebugs prefer warmer, more humid conditions
- Keep a close eye on centipedegrass, as it is a spittlebug’s favorite turf
Biological Control
Introducing natural predators can help keep spittlebug populations in check:
- Encourage the presence of ladybird beetles, lacewings, and spiders in your garden
- Attract birds by installing birdhouses and feeders close to infested areas
Chemical Control
Chemical treatments should be used as a last resort in case of severe infestations. Here’s a comparison of common chemical options:
| Chemical | Pros | Cons |
|---|---|---|
| Bifenthrin | Effective against spittlebugs | Non-selective; can harm beneficial insects |
| Carbaryl | Provides good control | Harmful to pollinators and mammals; potential environmental impact |
| Neem oil | Organic option; less harmful to beneficials | Requires frequent application; less effective against severe infestations; slow acting |
| Lambda-cyhalothrin | Fast acting; broad spectrum | Highly toxic to bees, fish, and aquatic invertebrates |
Remember to:
- Apply the pesticide only after carefully reading the label and following the instructions
- Always target adults and eggs at the same time for maximum effect
- Avoid spraying on hot days or when plants are in bloom to minimize harm to beneficial insects and pollinators
- Keep pets and children away from treated areas until the pesticide has dried and it is safe to return
By combining these cultural, biological, and chemical strategies, you can effectively prevent and control two-lined spittlebug infestations in your garden.
