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. If you already have grasshoppers you can use Bifen 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. Once the Bifen has dried it will be completely safe for pets and children to resume their normal activity in the areas that have been treated. The Bifen is safe to be used on anything non-edible in the yard and will not harm trees, bushes, or flowers.

Yes, Bifen IT is labeled for bed bugs & leaves a residual that will continue killing. However, it is not the top product that we recommend, we generally recommend using Temprid FX Insecticide. While they both have residuals, they take the Temprid back with them once they are in contact with it. You may also consider using one of our bed bug kits.

Bifen I/T is used in poultry housing and facilities as long as the chickens are removed from the area while you treat them. You should still be able to use it in their grazing areas with no issue since they are not actually feeding on the grass/potential seeds placed out but on the insects in that area after everything has dried. If you have any concerns with the Bifen I/T usage, another option that is safe to use in grazing areas is Essentria All Purpose. You still have to remove the chickens during the application but once dry is safe to return just like the Bifen IT. Neither product should have any effect on their eggs at all as long as you are following usage instructions. 

Bifen IT is safe for use around pets when used according to the label. You should always keep children and pets away from the away while you are treating, and then once the treatment is dry it is perfectly safe to allow pets to re-enter the area.

You can review all of the available options on our Mole Control page. Please let us know if you have any questions.

Bifen IT is labeled to treat active infestations inside as directed on the product label but would only kill those termites that actively make contact with a treated surface or are sprayed directly.  If you are dealing with subterranean termites, you want to use a product that has a "tranfer-kill" effect. Termidor SC is a great product to use to treat termites and prevention, or Termidor Foam for active only, both of which are non repellent and transfer back to the colony below ground. Please see our Termite Control Page. Scroll to the bottom of the page and find information on identification and treatment for termites.

Treat a four-foot diameter around each ant mound. Application should be made in late evening or early morning when it is cooler (65° - 80° when insects are most active. NOTE: A spray rig calibrated to apply 1 fluid oz. per 1,000 square feet of Bifen I/T in 5 gallons per 1,000 square feet contains the equivalent dilution (1 teaspoon per gallon) required for fire ant mound drenches in the spray tank.
