Bifen IT, Suspend SC, and Tempo SC Ultra should not be mixed together or sprayed within 30 days of one another. This could cause the products to not work as labeled and potentially would be dangerous as you would be overapplying unnecessary products into the environment. Please be sure to review the product labels for more information and complete application instructions. It is a good idea to rotate the products every few applications to prevent any possible resistance issues to the active ingredients.
Bifen IT can be reapplied every 30 days for most applications outdoors. Mix rates range from 0.18 to 1 fl oz per gallon of water per 1000 sq ft of area depending on the insects you are targeting.
Repeat applications should only take place if there are signs of renewed insect activity and must not exceed one application per 7 days.

While yes, insects can develop a resistance to the same active ingredients with the same modes of action, this usually takes years of exposure to that same chemical to develop a resistance. For a rotation insecticide with Bifen IT when targeting mosquitoes, Temprid FX would be recommended as this contains 2 active ingredients (beta Cyfluthin & Imidacloprid) to help prevent resistance.
View the Temprid FX product label for more information.
For mosquitoes key is to apply to the underside of leaves on trees/bushes which is there the adults lay during the day, as well as shady areas. You would not treat entire areas of the lawn that are in full sun as it is not habitable for them there.

It is advisable to wait at least 1-2 days after mowing to apply a product like Bifen IT, or any other chemical treatment application to your lawn, to avoid any unnecessary stress this may potentially cause to your freshly cut lawn.
While Bifen IT is labeled for mites it is not labeled specifically for rodent mites. The easiest method to control rodent mites that have entered your home is to physically remove them with a vacuum cleaner or wipe them up with a moist cloth. Mites are not automatically killed by a vacuum cleaner so freeze the bag to prevent the mites from crawling back out.
Locating the source and eliminating the hosts and nests is important to prevent further problems with these mites. Nests are usually located in attics, basements, or inside walls. If necessary, trap them with kill traps or glue boards. Spray the dead rat and its nest with a disinfectant. Removing the mite source (dead mice, rats, and abandoned nests) is very important. Unless you remove their source, rat mites will continue to seek human host infesting your house.
Bifen IT is labeled for flies, yellow jackets and wasps when applied per the product label rates. This is not a knockdown spray but will leave a residual of 21-30 days. Retreat as necessary if signs of renewed activity exist.
You may want to consider our Wasp and Hornet Kit which contains the residual insecticide Cyzmic CS, plus Wasp-X that is a contact kill aerosol to spray wasps and nest directly.
Bifen I/T can be used for mound drench application on fire ant colonies in the yard as well as broadcast spraying over the surfaces of the lawn.
Per the ant control and mound drench instructions from the Bifen I/T Product Label:
The best control will be achieved by using broadcast treatments in combination with mound drenches. This will control present colonies along with foraging workers and newly mated flyin queens. It is critical either to use high volume treatments or to irrigate prior to application if the soil is dry. Apply 1 fl. oz. per 1,000 square feet when using broadcast treatments. For mound drenches, dilute 1 teaspoon of Bifen I/T per gallon of water and use 1 to 2 gallons of finished dilution using sufficient force to penetrate the top and allow dilution to flood ant 39 channels. Treat a four-foot diameter around each ant mound.
Application should be made in late evening or early morning when it is cooler (65
