The effect of plastering in a house persistently infested with Triatoma infestans (Klug) 1934

The replastering of a house in Mambai-Goias, Brazil, as a measure to wall-in Triatoma infestans, is briefly described. Unfortunately, because the houseowner would not cooperate the roof tiles were not improved and eventually T. infestans reappeared at this site. A brief discussion follows of some aspects of house improvement in the vigilance phase of a Chagas Disease Control Programme. T. infestans appeared in the house described 51 and 258 days after the replastering.
