A convenient, economical, non-toxic and effective method and means for the control of insects by attracting the insects to a high concentration of an entomopathogenic fungus, for example, Metarhizium anisopliae and Beauveria bassiana, so that they are infected by the fungus and die. The fungi are placed in the environment to be treated using means which insure contact and infection of the insects with the fungi. In the preferred embodiment for the biological control of cockroaches, the roaches are ex- posed to the fungi by means of a contamination chamber having openings through which the cockroaches enter and come in con- tact with a living culture of a fungus which is pathogenic to cockroaches. The fungal spores attach to the roach, germinate and penetrate into the body of the cockroach, resulting in the death of the infected roach. Death takes approximately two to three weeks after contact with the culture. During this time, the infected roach disseminates spores of the pathogenic fungus throughout the infested areas which may subsequently infect other roaches. Given the proper envinmental conditions, the fungus sporulates on the cadaver of the roach and the conidia can be transmitted to other cockroaches, resulting in a further spread of the disease.
