Lawn shrimp (Arcitalitrus sylvaticus) were brought to our attention (and our office!) by an alert customer. She had found a few dozen unusual dead bugs in her house and asked for help with identification. Thrasher Termite & Pest Control staff identified the 3/8 inch long, flattened, reddish brown, shrimp shaped critters were Arcitalitrus sylvaticus, AKA Lawn shrimp. These creatures are actually a land-dwelling crustacean relative of shrimp and crabs.

Lawn Shrimp arcitalitrus sylvaticusLawn shrimp were introduced to California from Australia, most likely at the time eucalyptus trees were introduced to the state. Lawn shrimp populations are often associated with eucalyptus, ivy, and damp areas with extensive ground cover.

According to the Institute of Food and Agricultural Sciences Extension, lawn shrimp live on the surface (top 1/2 inch) of mulch and moist ground. “After rains, large numbers … can migrate into garages or under the doors of houses. There they soon die….They lose or gain moisture from their environment. Too much of a water loss results in desiccation, while too rapid a gain is also lethal. This is why they migrate out of rain-soaked soil to drier areas where they usually end up dying anyway.”

In the rare event that your home experiences and invasion of lawn shrimp, hold the cocktail sauce. These small, harmless invaders will die quickly and are easily vacuumed up.
