They can also be found under leaves and debris on top of grassy areas that have been wet for a while.

When you see a large number of black beetles near your lawn or garden, it’s best to call an exterminator immediately.

What Should I Do If I See Black Beetles On My Lawn Or In My Garden?

  • Don’t worry about black beetles on your lawn. They won’t damage your grass or harm your garden, so don’t try to get rid of them with pesticides.
  • Don’t kill black beetles. They are not harmful to people or pets, and they play an important role in nature by eating other insects like caterpillars that can destroy plants and crops.

Don’t squish, step on or vacuum up black beetles crawling across the yard they’re beneficial insects! 

If you must remove them from the area where you’d rather not see them (e.g., if they’re crawling around inside) use a fly swatter instead of stepping on them or blasting them away with a powerful suction device like a leaf blower/vacuum cleaner; 

Otherwise, everything around will get covered in their carcasses which may look gross but aren’t toxic either way.

So if this is the case, all you have to do is wait until they go away on their own (they’ll fly off at night). 

If they’re still around in the morning when everyone else has gotten up and started moving around, try spraying them with water from an outdoor hose (but don’t get too close or spray them directly).
