We investigated the number of Indian meal moths (Plodia interpunctella) captured by pheromone traps placed both inside and outside residential buildings in the Kanto region of Japan. The survey was conducted at 2 sites in Tokyo, 1 site in Saitama, 1 site in Kanagawa, and 1 site in Ibaraki, during October and November of 2016. At each survey site, traps were placed inside and outside residential buildings: indoor traps were placed on kitchen walls near refrigerators or cupboards, while outdoor traps were placed under eaves or on balcony floors. By the indoor traps at the Hachioji, Tokyo, three adult Indian meal moths were captured that were considered to have entered the building from outside. At the other sites, however, the indoor traps captured no moths. On the other hand, the outdoor traps captured 145 adults in total. These results show that P. interpunctella was active outdoors during October and November, although fewer moths were captured by the pheromone traps in November.
