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.
