You didn't pay attention or read far enough. It occurs in greenhouses, too. And 
"prayer plant" (Maranta sp.), which is a very common houseplant.

Iit doesn't attack citrus in California because the California state department 
of agriculture aggressively combats infestations due to infested plants brought 
in from out of state.

All this information crops up in the first two or three Google hits on 
"radopholus similis".

California quarantines plants from Alabama, Arkansas, Florida, Georgia, Hawaii, 
Louisiana, Mississippi, North Carolina, South Carolina, Texas, and Puerto Rico.
