Note that they may be hiding in the crevices of the soil as they do not like light.
  • If the bugs are not visible, you can the following:
  • Cut the bottom of a metal soup can and push it down two inches deep into the surface of your lawn.
  • Fill the can with soapy water.
  • Wait approximately five minutes. If you have chinch bugs, they will float to the top of the can.
  • Perform steps 1-3 in several areas of the lawn, including near edging. If there are five or more chinch bugs per can, the infestation is serious enough that this may incur irreparable damage to your lawn.
