Among the embodiments of the present invention are pest control devices ( 1010, 1110, 1210 ) each operable to detect the presence of pests. The pest control device ( 1010, 1110, 1210 ) has a bait ( 1032 ) that is consumed or displaced by one or more species of pest, a pest sensing circuit ( 1052, 1152, 1252 ), and a monitoring circuit ( 1069, 1169, 1269 ). The pest sensing circuit ( 1052, 1152, 1252 ) can be altered by pest activity. The monitoring circuit ( 1069, 1169, 1269 ) detects this alteration and reports it automatically or in response to an external stimulus or interrogation to indicate pest presence. |
