Japanese cockroach Periplaneta japonica (Stoll) was collected at a Japanese common wooden house and in a shrine of Hokkaido Jingu, and Maruyama Park in Sapporo city. In Hokkaido, this species was recorded only from the coastal area of the southern parts and Otaru city up to present. Therefore, these are the new records of this species from the landlocked city in Hokkaido, and the new record of invasion to a highly airtight house of Hokkaido.

Seventy-two houses infested by dark-brown ants, Lasius japonicus Santschi, were surveyed from April 2005 to September 2006 in Sapporo and neighboring cities. The ants were active in the warmer seasons, especially in June. The infested houses were categorized into two types: less than 5 years (30.6%) or more than 21 years (27.8%) after construction. These phenomena might be caused by changes in the external insulation in recent houses and the house deterioration in aged mortared houses.
