Laboratory and field research trials conducted within both
the United States and Canada to determine efficacy for control
of ground squirrels (Spermophilus sp.) showed 100% efficacy
in the laboratory and 94 to 98% efficacy when used according
to the label directions in the field.
Other Rodent Species, including Norway Rats (Rattus norvegicus)
have been tested in laboratory and field efficacy trials.
Lab tests trials showed 100% efficacy on Norway Rats, while
preliminary field trials produced promising results. A full
research trial required for PMRA and EPA approval will soon
be undertaken. At this time EXIT is not registered for control
of Norway Rats.
