Popis: Populations of Coptotermes havilandi and Heterotermes sp. were detected in soil and structures of San Cristobal and El Morro of the San Juan National Historic Site. This was the first record of C . havilandi in Puerto Rico. Baits containing a chitin synthesis inhibitor, hexaflumuron, were applied using in-ground and aboveground bait stations. It took 2–8 months to eliminate three populations of C . havilandi , but 13–15 months were required to eliminate four populations of Heterotermes sp. Due to the vast area of the San Juan National Historic Site, there are probably many more unseen populations of subterranean termites. There is a need for a routine monitoring program for early detection of subterranean termite infestations so that baits can be applied to eliminate detectable populations before severe and irreversible damage occurs to this historic site.
