Identification

• Beneficial nematodes are tiny worms you place in your garden that eat insects and dead plant matter under the soil. According to the University of Nebraska-Lincoln, nematodes are the most plentiful multi-cellular organism on the planet.
  
  

Function

• Nematodes help cut down ticks in your yard by eating their larvae beneath the surface. Not all nematodes eat ticks; when you purchase them, make sure you buy the variety that eats insects rather than decaying plant matter.
  
  

Considerations

• According to Pet Care Naturally, using nematodes is the easiest and most effective way to fight ticks in your yard. While you can use natural pyrethrums or diatomaceous earth as an organic way to kill ticks in your yard, nematodes are an all-natural, chemical-free solution.
