Identifying Lawn Shrimp

How to get rid of lawn shrimp

Lawn shrimp, scientifically known as Syncaris pacifica, are small, crustacean-like creatures that can become pests in lawns and gardens. They are native to the Pacific Northwest of North America but have been introduced to other regions, including Europe and New Zealand.Lawn

shrimp are typically less than an inch long and have a dark brown or black body with a white or yellow stripe running down the back. They have six legs and two long antennae. Lawn shrimp are often mistaken for other insects or pests, such as pillbugs or sowbugs, but they can be distinguished by their long antennae and the presence of a white or yellow stripe on their backs.Lawn

shrimp prefer to live in moist, shady areas with plenty of vegetation. They can be found in lawns, gardens, and even under rocks and logs. Lawn shrimp feed on decaying plant matter and algae, and they can damage lawns by feeding on the roots of grass plants.

Understanding the Impacts of Lawn Shrimp

Lawn shrimp infestations can have detrimental effects on lawns, impacting their health, aesthetics, and even economic value. Understanding the potential damage caused by these tiny crustaceans is crucial for effective management and prevention.

Lawn shrimp feed on the roots of grass plants, weakening their ability to absorb water and nutrients. This can lead to stunted growth, yellowing, and thinning of the lawn. In severe cases, entire sections of the lawn may die, creating unsightly brown patches.

Economic Consequences

Severe lawn shrimp infestations can also have economic consequences. Properties with damaged lawns may experience reduced curb appeal, potentially lowering their value. Additionally, the cost of repairing and maintaining lawns affected by lawn shrimp can be significant, including expenses for insecticides, soil amendments, and reseeding.

Prevention Methods

Preventing lawn shrimp infestations requires a combination of proper lawn care practices and the use of natural repellents and barriers.

Regular mowing, watering, and fertilization promote a healthy lawn that is less susceptible to pests. Mowing at a higher height (2-3 inches) provides shade and reduces soil moisture, making the environment less favorable for lawn shrimp. Proper watering practices ensure the lawn receives adequate moisture without becoming waterlogged, creating an inhospitable environment for lawn shrimp.

Fertilization provides essential nutrients for a healthy lawn, promoting vigorous growth and resistance to pests.

Natural Repellents and Barriers

Natural repellents, such as neem oil or garlic spray, can be applied to the lawn to deter lawn shrimp. Neem oil is a natural insecticide with repellent properties, while garlic spray has a strong odor that lawn shrimp find unappealing.

Physical barriers, such as diatomaceous earth or crushed eggshells, can be spread around the perimeter of the lawn to create a barrier that lawn shrimp are reluctant to cross.

Treatment Options

Once you’ve identified and assessed the extent of the lawn shrimp infestation, it’s time to consider treatment options. Chemical controls, organic methods, and home remedies are all viable approaches, each with its own advantages and disadvantages.

Chemical Controls

Chemical controls offer a quick and effective way to eliminate lawn shrimp populations. However, they can also pose risks to the environment and human health if not used properly. Always follow the manufacturer’s instructions carefully and wear appropriate protective gear.

Chemical ControlApplication
Carbaryl (Sevin)Apply granules or dust to the affected area, targeting the base of plants and soil surface.
DiazinonMix with water and apply as a spray or drench to the infested area.
MalathionMix with water and apply as a spray or drench to the affected area.

Organic Methods

Organic methods are less harmful to the environment and human health than chemical controls, but they may require more time and effort to achieve results.

  • Diatomaceous earth:Sprinkle this fine powder around the base of plants and along pathways where lawn shrimp travel.
  • Nematodes:These microscopic worms feed on lawn shrimp and can be applied to the soil.
  • Garlic spray:Mix crushed garlic in water and spray it on the affected area.

Home Remedies

Home remedies are often inexpensive and readily available, but their effectiveness may vary.

  • Salt:Sprinkle salt around the base of plants and along pathways where lawn shrimp travel.
  • Soap:Mix dish soap with water and apply it to the affected area.
  • Vinegar:Mix vinegar with water and apply it to the affected area.

Cultural Controls

Cultural controls are practices that modify the environment to make it less favorable for pests. These methods can disrupt the life cycle of lawn shrimp, reducing their population and damage to your lawn.

Crop Rotation

Crop rotation involves planting different types of plants in the same area in a sequence. This disrupts the life cycle of pests that are adapted to a specific host plant. For lawn shrimp, rotating between grass species, such as fescue and bluegrass, can help reduce their populations.

Companion Planting

Companion planting involves growing certain plants together that have beneficial effects on each other. Some plants, such as marigolds, are known to repel lawn shrimp. Planting these plants around the perimeter of your lawn or in between grass patches can help deter the pests.


Mulching involves spreading a layer of organic material, such as compost or shredded leaves, over the soil. This creates a physical barrier that makes it difficult for lawn shrimp to move around and access food. Additionally, mulch can improve soil health, which can benefit your lawn overall.

Biological Controls

Biological controls offer a natural approach to managing lawn shrimp infestations by introducing predators that feed on them. This method is environmentally friendly and can provide long-term control.

One effective biological control method involves using natural predators, such as birds and insects, that feed on lawn shrimp. Birds, such as starlings and blackbirds, are known to consume large numbers of lawn shrimp, while insects like ground beetles and parasitic wasps can also be effective in reducing populations.

Advantages of Biological Control

  • Environmentally friendly
  • Can provide long-term control
  • Cost-effective

Disadvantages of Biological Control

  • May not be effective in all situations
  • Can take time to establish
  • May require additional management practices

Case Studies and Success Stories

Documenting and sharing successful lawn shrimp management programs provides valuable insights into effective control strategies. These case studies offer real-world examples of how individuals and communities have overcome lawn shrimp infestations, providing practical guidance for others facing similar challenges.

One notable success story comes from a homeowner in the southeastern United States. After struggling with persistent lawn shrimp infestations for several years, they implemented a comprehensive management program that included cultural, biological, and chemical controls. Regular dethatching and aeration reduced the organic matter buildup that attracts lawn shrimp, while the introduction of predatory nematodes targeted the shrimp population.

Additionally, targeted applications of insecticides specifically formulated for lawn shrimp control provided effective suppression.

Positive Feedback

“After trying various methods without success, I was skeptical about another attempt at controlling lawn shrimp. However, this comprehensive approach has finally given me the lawn I’ve always wanted. The shrimp population is significantly reduced, and my grass is thriving.”
