While the southern states of the U.S. have long been the recipients of tropical colonizers and are at greatest risk for their establishment, global trade and transport have made it possible for exotic species to use virtually any entry point as a portal into the United States. We here report on two recent records of intercepted Hemidactylus spp. in the northeastern United States. Specimen 1.—A juvenile Hemidactylus (CAS 250102, 40.48 mm SVL) was intercepted alive by an Agriculture Specialist (U.S. Customs and Border Protection) at Highgate Fig. 1.
