Bifen IT is labeled to be used to treat for bee control as we highly advise looking at our Getting Rid of Bees Guide that will provide further information on how to do a proper treatment.
Bifen I/T is labeled to kill weevils of several different forms and has shown to be successful through the studies of many universities on rhododendren. You would need to spray the entire plant down to try and not only kill the weevils but also to hopefully repel them from coming in the first place. Good plant health is a key factor in eliminating and preventing weevils of all kinds. Bifen should work to kill some currently and the most in the spring. Just use heavy water volumes to push it through the soil and retreat as necessary for new activity. If for any reason you dont see the full control with the bifenthrin you can always try something like Acephate 97 as a systemic and use the Talstar as a foliar spray and as a general insecticide spray around your home to help keep down any other unwanted pests.
Bifen IT typically only take 1 hour to completely dry on a surface and will hold up very well in the rain, but you should have a minimum of 6 hours between your applicaton and rainfall or irrigation. Bifen IT is rainfast 6 hours after the application, and is recommended to be used with a pump sprayer.
It is not necessary to wear protective clothing, however, you can when using Bifen IT. It is recommended that you keep your pets and children out of the area until the product has dried completely. It is safe to return to the area once the product has dried completely. Please check the SDS for any additional information regarding carcinogenic.

Both products are great, however, if you want to use an "all in one" product, OneGuard will be the better option as this product is a multi-mode of action concentrate that provides long-lasting control of mosquitoes and other flying and crawling insect pests. It contains a powerful combination of knockdown agent, killing agent, synergist, and NyGuard Insect Growth Regulator (IGR) in a single product. It features controlled-release technology to ensure effective knockdown, kill, and control of insects. It has a dual mode of action to help increase efficiency, plus it reduces mosquito populations by preventing them from reproducing. It is designed to kill mosquitoes such as Aedes, Anopheles and Culex that may transmit West Nile virus, Zika virus and Chikungunya virus. Please be sure to review the product label for more information and complete application instructions. Also, please take a moment to review our Mosquito Control Guide here.
Bifen IT is labeled for flies and can be applied at 1 oz. per gallon of water per 1,000 sq. ft. as directed. However, because flies in general can be more challenging to control with spraying alone, we suggest you refer to our helpful Fly Treatment & Control Guide for treatment recommendations and for links to related products.
Yes, Bifen IT is labeled to kill grasshoppers.
No, Bifen I/T cannot be used in a thermal fogger or any type of fogger. It must be applied with tank sprayer-type equipment such as handheld, backpack, or large-volume tank equipment. If you'd like to provide our staff with what pest you are treating for and where we would be happy to make alternative recommendations to you.
Bifen IT will kill any gnats that come into contact with a treated area. You may want to look over our article on Getting Rid of Gnats for more information.
Bifen IT is labeled to treat for wasps, but it is not an instant knockdown. Bifen IT will kill wasps that come in contact with it. Retreat after 21 days 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 to kill insects very quickly when you locate nests.
You should not need a full respirator mask when using Bifen IT in a mist blower, but we would recommend at least wearing long sleeves, long pants, socks and shoes, and a nose and mouse mask for extra safety. Our KN95 masks would be fine for this application. Of course, anytime you are applying product vertically, be sure to wear adequate eye protection as well.
