Bifen IT is for insects only and will not treat fungus or other causes of spots on plants. It is important to identify the disease on your plants so that you can select a product that will work for your needs. You can contact your local cooperative extension office and speak to the master gardener on staff for help identifying the type of disease on your plants
We are not sure what type of worm would be considered a "red worm" as you have described. Â If you are referring to earthworms,Â Bifen ITÂ isÂ not labeled for earthworms, because they are a beneficial but it may cause harm to them if they contact a treated area. Â Though they are pretty protected by the mucus on their bodies. This small amount of product needed to kill tiny insects would not be enough to harm a bird if they were to ingest a worm that would have contacted the product.
You do want to spray Bifen IT over the sod periodically to keep the rest of the population on top of the new sod down.
Bifen IT cannot be used on areas that will be used for grazing by animals.
Yes, Bifen IT can be used both indoors and outdoors.
We do not recommend mixing together two pyrethroids such as Bifen IT and a permethrin product. These products are too similar, and you could create a repellency issue rather than allowing insects to actually contact the treated areas. If you want to add something to Bifen IT for faster intiial knockdown, then we suggest a pyrethrin and/or PBO product such as ExciteR Insecticide.
We recommend that you do not apply Bifen IT when birds are present. All surfaces/areas should be completely dried and ventilated prior to the return of the birds.
Bifen IT will not treat for roundworms in a yard. We do apologize but we do not carry a product for the lawn that is labeled for roundworms and we are not aware of any products available that would take care of this issue.
Generally it is necessary to take non chemical steps to treat this. Keeping dogs from a contaminated area for at least 1 year will prevent infestation and if that is not possible then removing and replacing the soil in area. Removing feces from the area as well when dropped is needed as well.
