The possibility of Metarhizium anisopliae fungi to erraticate the mites is real . Researcher at the New York Botanical Garden is investigating the potential use of a commonly found species of microscopic fungus as a biological control of the northeastern tick, which causes the Lyme disease. The researcher found that a strain of the fungus Metarhizium anisopliae destroyed 80% of the northeastern tick. Different strains of this fungus are already used in several countries for pest control, including in the United States where the strain ESFI is used commercially against cockroaches. Insecticidal fungi like Metarhizium anisopliae kill certain insects by invading the body and multiplying throughout. The insect dies from tissue destruction caused by the proliferation of the fungus and the production of fungal toxins.. The fungus then emerges from the body in the form of spore- producing filaments.. Scattered by the wind and rain, the spores spread the infection to other ticks. Because of the danger of the fungal toxins contaminating the environment ,I wonder if  Sylvan Bioproducts who will be producing and formulating this fungi are well aware of  that these toxins could contaminate the brood section.
