found that P. fuliginosa has become an important pest in buildings in 

 several areas of North Carolina since first being identified in 1964, as a 

 result of its continuing spread into previously uninfested areas. Around 

 Florida suburban houses, Brenner (1988), Brenner and Patterson (1988), 

 and Patterson and Koehler (1989) trapped P. fuliginosa most often and 

 Eurycotis floridana (Walker) second. Blatta orientalis, the other non- 

 wood cockroach trapped, was considered an indoor-outdoor species by 

 Mallis (1982). Beatson and Dripps (1972) reported on three long-term 

 infestations of B. orientalis, stating that it was usually considered an 

 indoor species in Great Britain. However, its importance as a domestic, 

 indoor species in Raleigh and North Carolina seems to be diminishing 

 (personal observations by the senior author and communications with 

 various pest control company personnel). The reason for its apparent 

 decrease is unknown.
