During a feeding trial conducted with a probiotic (Deodoricum) containing Bacillus spores a decrease in the stall fly population was observed. The aim of this study was to examine on the one hand the larvicid effects of cultures of Bacillus sp. in various stages of growth and on the other hand the inhibitory effects of cultures of Bacillus sp. and dried Deodoricum preparates on egg laying by gravid adult females. Media for sustaining the larvae containing spores at concentrations killed a large proportion of the larvae thus reducing their numbers to a significantly lower level than in the case of other samples and that of controls. The larvicid effect was proportional with the number of spores. In the experiment with adults, the preparate with the dried Deodoricum containing spores and the fermentation solution in a concentrated fermentation solution's inhibition of egg laying by gravid females.
