Is Archer IGR or Nyguard IGR effective against oriental cockroaches and which would be better for outdoor use?

I see on the label it only lists asian, german, and brown-banded roaches. Also looking at Nyguard and that says the same.

Answer:

Both the Archer IGR and Nyguard IGR are labeled to treat for both asian and oriental  roaches (which are the same type of roach). If you are using this for an outdoor application you would want to choose the Archer since it is more photostable in an outdoor application.
