Bifen IT is mixed at 1 fl oz per gallon of water per 1,000 sq ft monthly to the listed exterior areas. For 3/4 acre, you will be applying approximate 33 fl oz per treatment to cover 32,670 sq ft.
For most pests, you will use 1 oz. of Bifen IT per gallon of water to cover 1,000 sq ft. Please refer to the product label for complete application instructions.
When using Bifen IT for ticks, there can be several variables. How long it takes the ticks to die after they come into contact with a treated area will depend on a number of factors, such as the age of the tick as well as how long they stayed in contact with the treated area, how long it has been since the area was treated, and the concentration that was used to treat the area. Typically it can take anywhere from a couple of hours to a day or so for them to die. It can take several weeks for you to stop seeing ticks completely because ticks like to stay hidden, which also means they could be staying away from treated areas. We recommend doing follow up treatments every two weeks at the highest usage rate of 1 oz of product per gallon of water until you do not see any ticks.
Yes, Bifen IT is toxic to fish and other aquatic life. It should not be used near water.
Bifenthrin and Bifenazate are used to treat different types of insects. Bifenthrin is mainly for general pest control use and is an ingredient in products such as Talstar P and Bifen IT. Bifenazate is a type of miticide and is an ingredient in products such as Floramite SC and Sirocco Miticide. We would not recommend rotating these two products for mite control. Bifenazate is a good active ingredient for spider mites, as well as Abamectin, which is the active ingredient in Avid 0.15 EC.
While you could tank mix the two, the Mosquito Barrier is going to work against the effectiveness of the Bifen I/T for probably at least the first week or two. You are spraying Bifen on surfaces moquitoes would land on and harbor in so that when they touch the treated surface they pick it up on their bodies and die from it. If you are spraying Mosquito Barrier you are using it to repel the mosquitoes away from areas you dont want them or are trying to keep them from harboring. So essentially by mixing the two together, you are repelling the mosquitoes away from the Bifen I/T so it would not affect them. Outside of an initial contact kill the mosquito barrier isn't going to provide killing action for you long term, only repellency. Bifen is actually the better product to use on a consistent basis in main target areas on the property where mosquitoes would be found, and use the Mosquito Barrier around patios and other "hangout" areas to keep them at bay until they have died from landing on the Bifen-treated surfaces.
Yes, Bifen IT can be used both indoors and outdoors.
We recommend that you do not apply Bifen IT when birds are present. All surfaces/areas should be completely dried and ventilated prior to the return of the birds.
Bifen IT is mixed at the rate of 0.125-0.25 oz. per gallon of water for bagworms.
There is no valid reason to mix synthetic pyrethroids such as Bifen IT and Onslaught Fastcap together. This would not make either product work better or produce better results. However, it could make treated areas repellent to bugs, lessening the effectiveness of the treatment. Neither product can do its job of killing insects if the insects are avoiding the treated areas.
Bifen IT is available for licensed professionals to apply in New York State. We are not able to ship to homeowners but whether you could legally use it would be something you need to ask of the local department that handles pesticide regulations.
There is no waiting period to apply Bifen IT after aeration or seeding.
Bifen IT may be applied at the low, medium and high rate of either 0.33 oz./gallon of water for prevention, low level infestations, 0.5 oz./gallon of water for general indoor or outdoor use, or 1.0 oz./gallon of water for severe infestations, less frequent treatments, longer residual, quicker knockdown. You will apply 1 gallon of finished solution every 1,000 square feet when using a hand pump sprayer.
Please refer to the product label for complete application instructions, and use as directed.
Bifen IT has not been shown to be very effective at controlling Raspberry Crazy Ants. Termidor SC used outdoors and Phantom used indoors have been the most effective products to control crazy Raspberry Ants. Ant baits and synthetic pyrethroid insecticides do not seem to do an effective job controlling this ant species. Texas A&M University has done extensive research regarding these ants and you can find detailed articles on their extension website.
