It is not a product I recommend because it contains a chemical called NAA.

The hormone 1-Naphthyl acetic acid (NAA) does not occur naturally. Under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), products containing NAA require registration with the Environmental Protection Agency (EPA) as pesticides.

The sale of Bio S.I. is prohibited in Oklahoma, Minnesota, and Oregon as an unregistered pesticide.
