Contamination in the lab during work..

I am working on the penicillium culture in the lab. But these days i am facing contamination in my lab of Aspergillus.I fumigated the lab and the incubator several times but i  could not get rid of it. I even swabbed the  incubator but of no success. I thought may be these because of the contaminated plates but even after autoclaving the problem was there as it was earlier. Please sugeest me some measure to control the aspergillus contamination as it is severly affecting my work.
