| IPM scouting in woody landscape plants > parasitic wasps |
| There are over 40 families of parasitic wasps. A few commonly seen in the land-scape are listed in this guide. |
 |
The oystershell scales with emergence holes in them have been parasitized by wasps. These tiny wasps (1 to 2 mm long) do not sting people. Several wasp families are known to parasitize scale insects. |
