Bifen IT is safe for plants if used as directed.
Bifen IT can be sprayed 3 feet up the side of the house, and 3 feet into the soil all the way around the perimteter foundation of the home. When treating for fleas, you will need to apply under decks, under trees, in places where leaves or other yard debris accumulates or areas where dense shrubbery exists. There is little need to spray open, sunny areas, dry and dusty areas or hard surfaces such as patios or driveways as fleas will not be able to develop in those areas. When treating for noseeums, you want to focus on treating those same areas, along with the understands of tree canopies, interior of shrubs and bushes, and damp areas in your lawn.
Bifen IT will not kill flowers if used as directed.
Bifen IT does not require the use of a surfactant unless you are treating for mites and/or spider mites per the product label.

Bifen IT is not labeled for use in drains. Roaches can be seen coming out of drains because more than likely they were looking for a water source. For the best roach control, we recommend using a Roach Control Kit. Please view our How to Get Rid of Roaches article for other tips and information.
Bifen IT can be applied monthly (30 days) outside the home and every 3 months (90 days) inside around the cracks and crevices.

You can use a temporary marking dye such as Turf Mark Blue with the Bifen I/T or any insecticide you plan to use for tick control. Bifen would be a great choice, and in the areas of the property you suspect the highest populations of ticks, you can mix in an IGR such as Archer IGR to help stop their reproductive cycle and reduce the amount of future generations you would be contending with in the yard. We also have a handy Tick Control Guide which you can review for tips to get the most out of your treatment, including how to videos and step by step instructions and recommendations.
Yes, Bifen IT will help control carpenter bees when it is applied to surfaces where the carpenter bees land. We also recommend dusting the carpenter bee holes with an insecticide dust such as Delta Dust to help kill any larva inside. Do not plug the holes for at least 30 days after dusting to prevent the developing larva from drilling a new hole to exit.

When using Bifen IT for armyworms irrigation is not necessary. You actually need to try to have no irrigation or rainfall for at least 24 hours after the application. Under chinch bug treatment it does advice that in order to optimize the penetration of the insecticide you can water the area prior to the treatment. If grass is being kept at a long mowing height or if the thatch layer is excessive, use higher volume treatments. It may be necessary to use higher application rates (up to 1 fluid oz. per 1000 square feet) to control populations made up of both adults and nymphs in mid-summer. Complete instructions are on the product label for each pest as well.
Bifen IT is applied at 0.25 fl oz- 0.5 fl oz per gallon of water per 1,000 sq ft. NyGuard IGR is mixed at 4ml to 8ml per gallon of water per 1,000 sq ft .
