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 labeled for Indian Meal Moths, however, we do not have a product that is labeled to be sprayed in the actual fireplace. You may spray outside edges and surfaces of the fireplace but not inside or in the chimney/flute areas.
Moths are attracted to light sources, including fireplaces therefore it’s a common access point for them to enter the home. An easy way to eliminate Indian Meal Moths in a fireplace would be to simply light a standard to good size fire and let it the fire burn for atleast 20-30 minutes. Heat temps between 120-140 °F is hot enough to kill Indian meal moths.We would recommend reviewing the Indian Meal Moth Treatment Guide for alternative product recommendations and more helpful tips.

Per the ant control and mound drench instructions from the Bifen I/T Product Label:
The best control will be achieved by using broadcast treatments in combination with mound drenches. This will control present colonies along with foraging workers and newly mated flyin queens. It is critical either to use high volume treatments or to irrigate prior to application if the soil is dry. Apply 1 fl. oz. per 1,000 square feet when using broadcast treatments. For mound drenches, dilute 1 teaspoon of Bifen I/T per gallon of water and use 1 to 2 gallons of finished dilution using sufficient force to penetrate the top and allow dilution to flood ant 39 channels. Treat a four-foot diameter around each ant mound.
Application should be made in late evening or early morning when it is cooler (65
