Absolutely. When Exciter and Bifen IT are tank mixed you will have a spray that offers a fast knockdown and a long lasting residual for most insect pests.

Bifen IT is labeled to eradicate ticks. How long it takes the ticks to die after they come into contact with a treated area will depend on a number of factors. It will depend on the maturity of the tick as well as how long they stayed on 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 indoors because the ticks like to stay hidden which also means they could be staying out of treated areas and eggs may hatch out prolonging the infestation. 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. It is also recommended to add an insect growth regulator such as Archer IGR to impede the reproductive cycle of the insect. For more information on treating ticks, please check out our article on Tick Control.

Bifen IT can be used to help control cluster flies indoors and outdoors. If the cluster flies have already made their way indoors, they will be harder to control because they usually hide in a wall void or other inaccessible area and are only visible when the house warms up. If the cluster flies are in an attic or drop ceiling or other dark area, a fly light would do a great job controlling the population. Using small fly lights such as the Fly Web in the house would also help to catch the flies. Spray Bifen IT directly on baseboards, window frames, door frames, and places where utilities (pipes, wires, cables) enter in to the building and any other crack, crevice or gap where insects can enter.

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. You just want to make sure you apply the right amount of products per gallon and per 1,000 sqft.
