Beauveria bassiana strain 447 (128815) Fact
Sheet
Summary
Beauveria bassiana strain 447 is a naturally occurring fungus that is approved for indoor use as an
insecticide in bait stations to control individual fire ants and other ants (but not colonies). The fungal
spores infect the ants, which soon die. The fungus is not toxic or infective to mammals, and exposure
to the public and the environment will be minimal to non-existent. Therefore, no adverse effects are
expected on children, adults, pets, or the environment when the bait stations are used as directed.
I. Description of the Active Ingredient
Beauveria bassiana strain 447 belongs to a group of fungi that are found throughout the world. The
infection begins when a fungal spore starts growing on the outer skeleton of a host insect, and the
infected insect soon dies.
II. Use Sites, Target Pests, And Application Methods
o Use Sites: Typical use sites include spaces under sinks, toilets, and washing machines
where ants may occur. The bait stations cannot be used where they may contact food,
such as in food handling areas, or on food utensils.
o Target pests: Fire ants and other ants found indoors.
o Application Methods: The fungus is firmly attached to the inside of a bait station, which
is placed at non-food sites as indicated on the label.
III. Assessing Risks to Human Health
Whether or not a substance poses a risk to humans or other organisms depends on two factors:
how toxic the substance is, and how much of it an organism is exposed to. Therefore, the EPA
considers toxicity data and exposure data in determining whether to approve a pesticide for use. No
adverse human health effects are expected from use of Beauveria bassiana strain 447 in bait
stations. The bait stations are designed to prevent adults, children, or pets from being exposed to
the fungus. In addition, laboratory studies show that the active ingredient is not toxic or infective to laboratory animals when eaten or inhaled. The fungus grows only at temperatures lower than
human body temperature, so no infection is expected.
IV. Assessing Risks to the Environment
No harmful environmental effects are expected because the bait stations are approved only for use
indoors. Because the active ingredient is firmly attached to the inside of the bait station, no outdoor
exposure is expected. EPA will require additional studies if the bait stations are proposed for outdoor
or other additional uses.
V. Regulatory Information
Year Beauveria bassiana strain 447 was registered (licensed for use): September 2002
Number of registered end products ( September 2002): One product (BAITS MOTEL Stay Awhile -
Rest Forever™ )
VI. Products Directed Against Public Health Pests
EPA defines a public health pest as any organism that can cause or transmit human disease, or can
cause human discomfort or injury. Fire ants are categorized as a public health pest. To help protect
the public’s health, EPA requires registrants of products used against public health pests to
demonstrate that the product meets specific standards for effectiveness as well as for safety. The
product containing Beauveria bassiana strain 447 for use against fire ants and other ants has met
the required standards for effectiveness.
