Results of a controlled trial of the acaricide Paragerm on Dermatophagoides spp. in dwelling houses

Abstract

The effect of Paragerm spray from either a hand pressurized can or from a general room mist device (MCR device) on mattress mite populations was compared with the effect of a control spray. After 1 mo., a reduction in mite population due to the cleaning procedures was evident in the control treated mattresses; Paragerm treated mattresses had significantly fewer mites. Of those treated with the aerosol can spray, 9 out of 15 were mite free. Dissection of the mattresses showed that some mites survive and they could form the nucleus from which reinfestation could occur.
