Bifen IT is safe for plants if used as directed.
There is no specific or ideal time of the day for spraying Bifen IT. Some people opt to spray outdoors in the early morning, when there is a lessor amount of insect activity. You can refer to the product label for complete application instructions, and use as directed.
Yes, Bifen IT is labeled to treat for wasps, but it is not an instant knockdown. Bifen IT will kill wasps that it comes in contact with it. Retreat after 21 days if signs of renewed activity exist. You may want to consider our Wasp and Hornet Kit which contains the residual insecticide Cyzmic CS, plus Wasp-X to kill insects very quickly when you locate nests.
We really haven't had anyone with this particular issue in the past but we do have an idea of what might be happening. Moles eat insects. They have to eat a lot of insects every day and have huge appetites. We think it is possible that the Bifen IT has killed their food source and they are searching all over for more food. Once they realize there is no food to be had they should move on quickly. You can also try trapping or baiting if they are not moving on fast enough for you. You may also want to look over our mole control guide for more information.
Only the applicator should be present during the application of Bifen IT until everything has dried completely and then others can return. You can treat the exterior once monthly and quarterly to interior cracks and crevices.
Bifen IT is safe to use around livestock premises as long as the animals are NOT grazing in the treated areas. After the application, you need to wait until the area is completely dry before letting the animals back onto the treated areas.
Bifen IT is labeled to treat active infestations inside as directed on the product label but would only kill those termites that actively make contact with a treated surface or are sprayed directly. If you are dealing with subterranean termites, you want to use a product that has a "tranfer-kill" effect. Termidor SC is a great product to use to treat termites and prevention, or Termidor Foam for active only, both of which are non repellent and transfer back to the colony below ground. Please see our Termite Control Page. Scroll to the bottom of the page and find information on identification and treatment for termites.
Yes, Bifen IT is labeled to control scorpions as directed.
Yes, Bifen IT is safe for applying to trees and lawns as directed on the product label.
Bifen IT is not recommended for bedbug control. We normally recommend one of our Bedbug Kits as they contain all of the necessary products for a complete bed bug treatment. Please take a moment to look over our Bed Bug Guide for more information on how to implement a successful bed bug treatment program.
Spotted Lantern Fly is an invasive pest mostly found in certain areas of Pennsylvania, New Jersey, and New York right now.

Some folks are treating trees with dinotefuran, although since these products are not yet labeled for this pest, we cannot be certain as to the efficacy.
can be used as trunk and foliar spray where you have found activity, and the manufacturer has a Supplemental Label you can review on how to use it for that pest. You would use 0.25-0.5 oz per 1000 sq/ft per gallon.
Bifen IT cannot be used in the Vector Fog C100. Riptide 5.0% Pyrethrin ULV is one of the best insecticides to use with the VectorFog C100 ULV Cold Fogger. It does not provide any type of residual, but it will kill the insects that it touches. It provides effective control of a wide range of insects including mosquitoes, stored product pests, cockroaches, biting insects, crawling insects, flies, and more without oil residues or oil-related issues. Riptide can be used undiluted and diluted.
Bifen IT is just an insecticide, so it will not harm the grass or other desirable plants. The only concern we would have is if you have newly germinating grass then you want to be careful not to put too much stress walking over it or pulling a sprayer over it.
Typically mosquitoes are not going to harbor in the lawn where the Bayer granules were placed. They are usually found in bushes and dense foliage areas. You can safely spray all bushes/hedges/ground covers and any areas you feel mosquitoes may be present on a monthly basis with Bifen I/T.
Yes, Bifen IT is an excellent option for boxelder bugs. Be sure to spray around the perimeter of the home, around windows, doors, etc. where the bugs could get indoors. You should treat once a month until the first frost. This product can also be used indoors around the perimeter of your home. The mixing ratio is 1 fl. oz. per gallon of water.
Bifen IT is not labeled for beneficial insects like butterflies. However, it is not really selective so it has the potential to kill them if they come in contact with a treated area. To avoid contacting beneficial insects, apply in the early morning or late evening when they are less active in the area. We would also recommend avoiding application to blooms to limit contact. A better option would be to use Mavrik Perimeter. There is no lingering odor or visible residue, and when dry, it is non toxic and non repellent to honey bees. We would still recommned you apply in the early morning or late evening when they are less active in the area
Bifen IT should only be applied to interior cracks and crevices quarterly (where floor meets the wall) and monthly to listed exterior areas as directed.
