Bifen IT cannot be applied to edible vegetation. We would recommend using a product like Fertilome Tree and Shrub Systemic Drench. This product is labeled for boring weevils in Pecan trees.
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
Bifen I/T is a great product for earwigs and a large variety of other insects as well. You will spray Bifen indoors around baseboards and cracks and crevices, and outdoors around window and door frames, and around the foundation of the home 2-3 feet up on the side and 2-3 feet out on the ground. Earwigs like moisture and dark areas so if you have any mulch or pinestraw against the home or close by in the yard, turn those areas to help dry them out and soak them down with the Bifen to help kill anything living there. Children as well as anyone other than the person applying the product need to be out of the area being treated while the product is being applied and until everything is fully dry. Once all surfaces are dry it is completely safe for everyone to return.
There is no waiting period to apply Bifen IT after aeration or seeding.
You can apply Bifen IT indoors and outdoors for flies in general as long as you make sure none of the spray winds up in the lake. If contaminating the lake is a concern for you there is a product called Essentria IC3 that can be used around water without worry of hurting any aquatic life. Essentria IC3 is a broad-spectrum natural insecticide that works just as well as the synthetic insecticides but without the aquatic toxicity issue.
We would recommend using a product like Bifen IT. It is labeled for over 75 different pests. It is non-staining, odorless, and can be used both indoors and outdoors.
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.
Bifen IT cannot be used on areas that will be used for grazing by animals. Please let us know what you will be treating so that we can offer a product that will fit your needs.
Unfortunately the state of Connecticut has limited most of the products out there on the market these days that can be shipped into the state without having a license to purchase them. Pest Xpert Home Barrier? would be one option of a comparable insecticide spray to Bifen IT that could be used in CT. An all natural option that works similarly is Essentria IC3 and can cover a wide range of pests and usage areas like the Bifen IT as well.
Bifen IT is mixed at the rate of 0.125-0.25 oz. per gallon of water for bagworms.
Bifen IT would be a good choice for grasshopper control. You should start applications before the grasshoppers have a chance to hatch for best control. You should thoroughly spray your lawn and water in the application with about a .25 in of water to help the product get past the thatch layer and into the soil where grass hoppers actually develop. If you already have grasshoppers you can use it at the highest usage rate of 1 oz of product per 1 gallon of water for the quickest knockdown. Use sufficient amounts of water to help the product get to the soil layers. It is safe to be used on anything non-edible in the yard and will not harm trees, bushes or flowers.
