Lawn shrimps are usually pests to humans but are not harmful.


  • Approximately 5 mm to 20 mm (3/16 to 3/4 in) in length
  • Species can vary in color from pale brown, greenish, to brownish black when they are alive and red in color when they die
  • Their bodies are laterally compressed and they lack a hard covering that is common in most crustaceans
  • The abdominal segments are often fused
  • Two pairs of antennas, one set being extremely small
  • Mouthparts that chew and feed off organic or decaying animal matter


  • Moist areas after rain
  • Light


  • Remove moisture from wood piles, flower pots, or any other stationary object they may live under
  • Get rid of humid, high-moisture habitats from entry points to your home
  • Sealing thresholds of doorways will keep these pests out
  • Any good perimeter pest control product should help
  • If any lawn shrimps appear, they can easily be swept up and discarded in the trash bin
