We are not sure why Bifen Granules does not have roaches on the label, but it is the same product as Talstar PL Granules, and roaches are listed on the Talstar granule product label. Please take a few moments to review our treatment article on How to Get Rid of Roaches for a successful roach control program. We do carry Roach Control Kits.
Because granules can last longer than a liquid residual, we don't recommend reapplying Bifen L/P Insecticide Granules sooner than 30 days.Granules wouldn't be the best option because the granules will usually sink below the thatch layer. When treating for fleas, it's better to use a liquid insecticide, you can use Bifen IT. With Bifen IT, when treating for active fleas, you can re-treat every 14 days. A liquid insecticide is better because the residual will be in the soil, thatch and grass blades as well, offering a better residual. Once you have it under control, you can continue to treat every 30 days, especially if those around you are not doing anything to control the flea activity. Take a look at our Flea Prevention Guide, Step 3, for more tips for Outdoor Yard Flea Prevention.
We recommend to continue using the Bifen L/P Granules for outdoors to protect your lawn from a broad range of insects. We do recommend treating in your wall voids and behind your outlets with an insecticide dust that will leave a long residual such as Delta Dust. It is water resistant and will last up to 7 months. To do a complete treatment we recommend our Roach Control Kit Rotation A. This kit comes with several products that should be used together to eliminate roach infestations.

Bifen L/P Insecticide Granules are labeled for armyworms and will do a great job controlling this pest. When treating for armyworms to ensure optimum control, irrigate the treated area with up to 0.1 inches of water immediately after application to activate (release from the granule) the insecticide. This product is not one that will kill the listed pests on contact. It will take time. There are several factors like the severity of an infestation that will play a part in how long it takes to gain complete control. It could possibly take a few weeks for full control. The product will leave a residual that lasts in the soil for 2-3 months.

Please refer to the product label for complete application instructions for the insect(s) you are targeting.
