You do not need a professional applicator’s license to purchase Bifen IT for use in Lousiana if you are applying to your own home or property. 

Bifen IT is a great product for all the insects you have mentioned, but another good product to be used outdoors is Cyzmic CS. That is because Cyzmic CS has a CapVantage Micro Encapsulation which means that each droplet of insecticide is encased in a protective microscopic capsule, providing a long residual, even in direct sunlight or other harsh weather conditions. The only insect Cyzmic CS is not labeled for that you mentioned is crane flies. Most products are still only going to provide a 30 day residual outdoors in the summer. Be sure to check out our Pest Guides for more details about the most common structural pests.

Bifen IT will not harm, inhibit, or promote any kind of growth in turfgrass when used at the label rates. Apply at 1 oz per 1,000 sqft for most insects with a minimum of .5 gallons per 1,000 sqft.  

When applying Bifen IT for mole crickets you should use 1oz per gallon of water. Per the product label:

Mole Cricket adults: Since the preferred grass areas are subject to constant invasion in early spring by the active adult stage, it can be difficult to maintain control of adult mole crickets. It is ideal to treat the areas as late in the day as possible and water immediately after application with up to 0.5 inches of water. To ensure maximum contact when soil is dry, it is necessary to irrigate prior to treatment to bring the adult mole crickets closer to the soil surface. To obtain optimal control of potential nymphal populations, the grass areas preferred by adult mole crickets should be treated immediately prior to the peak hatch stage. 

Mole Cricket nymphs: Treat grass areas that are preferred by adult mole crickets in the spring just before peak egg hatch. Young nymphs are more vulnerable to insecticidal treatment at this stage because they are close to the soil surface where the insecticide is most concentrated and thereby providing the most efficient control. For larger more damaging nymphal stages later in the year, it may be necessary to use higher application rates more frequently. It is ideal to treat the areas as late in the day as possible and water immediately after application with up to 0.5 inches of water. To ensure maximum contact when soil is dry, it is necessary to irrigate prior to treatment to bring the adult mole crickets closer to the soil surface.

Bifen IT can be tank mixed with other products in a tank sprayer. For something like humic acid, we always recommend a small jar test for compatibility before mixing a full tank. It can also be mixed with other herbicides as long as the herbicide label does not state otherwise.

It will depend on what you are applying it for. For instance, if you are trying to control insects that walk on the blades of grass or around the thatch layer, if you use too much water, you could push all of the product below the thatch and those insects may not be affected by the application. If you are targeting insects that are below the thatch such as chinch bugs, more water can help you get the water where you need it to be. Please refer to the Bifen IT product label for complete instructions on your target pest.

There isn’t a set window of application that has to be maintained or followed, but we often recommend giving a few days between treatment if you are applying several items to the lawn to avoid any unnecessary stress to it. Pre emergents and fertilizers usually require a higher water volume or watering in after application, whereas the Bifen I/T would use less water per surface area and would need to remain on the surface and not be washed away. Application a few days after a pre em or fertilizer application would be fine.
