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.
View our Mosquito Treatment Guide for more information on successful treatment program.
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.
You will need to wait 24 hours after/before mowing to apply Bifen IT

We generally recommend using a pyrethroid such as Bifen IT or Permethrin SFR as a preventative treatment in late spring/summer before the egg hatches to protect trees. If trees are badly infested, then they should be removed and either chipped or burned.
Keep in mind that trees that become infested with bark beetles are almost always susceptible due to some other existing weakness such as drought or disease.
