Seasonal studies on the distribution of dust mites showed maximum concentration between June to August during which the atmospheric temperature, relative humidity, and rainfall were maximum, and it accounts for 37.7% of total mite population (Figure 1). Acarus spp. was found maximum during the month of August (278/500 mg) followed by May (224/500 mg), whereas, Blomia spp. was maximum during the month of July (286/500 mg) followed by June (263/500 mg) and March (243/500 mg), respectively. Similarly,Dermatophagoides spp. was found maximum during the month of July (434/500 mg) followed by March (356/500 mg). Least population was recorded from November to February, that is, winter season. Indoor dust mite counts showed significant correlation with the monthly mean rainfall (r = 0.783,
