House fly intensity at five different poultry farms in Namakkal region of Tamil Nadu was monitored by spot cards. A plain white sheet of 12.5×7.5 cm square was pinned to thermocole of similar size and tied to cages above two feet from the floor in narrow caged poultry houses and three feet above from the floor in high rise caged poultry houses. After 24 hours, the spot cards were removed and the regurgitation and faecal spots made by adult flies were counted. The mean number of fly specks per card was 59 ± 8 in farm-I, 195 ± 28 in farm-II, 63 ± 12 in farm-III, 34 ± 5 in farm-IV and 101 ± 19 in farm-V. About 50 gms of manure collected in different points of selected farms were pooled and moisture estimation was carried out by oven drying method. The moisture content of manure was 67.49, 86.32, 48.64, 41.56 and 79.11 per cent in farm-I, farm-II, farm-III, farm-IV and farm-V respectively. Higher fly population was observed in farms (I, II and V) that had manure moisture content > 60 per cent and mild to moderate level was noticed in farms (III and IV) with moisture level ranged between 40 and 50 per cent.
