Shaking the Bifen IT prior to mixing is not necessary unless the product has sat for a long period of time and you can see some separation or settling of the ingredients. If so, you can shake it until it goes back into emulsion and then use it.
Bifen IT can be used as long as animals are out of the area during treatment until dry. Please be sure to refer to the product label for complete instructions on application.
Bifen IT is safe to be used around a well and with well water as long as where you are treating isn't within 3 feet of the well.
Bifen IT will last up to 30 days outdoors, keep in mind a surfactant is not required with this product. You can reapply at 7 day intervals at the lowest rate if needed for heavy pest pressure or once a month at the high rate.
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.
Bifen IT can take several minutes or longer to kill a listed pest that contacts the treated surfaces. It is mixed at 1 fl oz per gallon of water per 1,000 sq ft monthly to the exterior areas and quarterly to the interior crevices. Eliminating springtails can take time. Springtails indicate that there is a moisture issue because they breed in walls or under slabs where a moisture issue may exist. Typically, pesticides alone will not take care of a springtail problem. It is required to fix whatever moisture issue is causing the problem. You should read our "How To Get Rid of Springtails" article for further information.
That is correct, the Bifen IT 3/4 gallon does not have a measuring reservoir. You will need a separate measuring device to measure out the correct amount of concentrate. You could use any measure cup as long as it is designated just for insecticides.
