Bifen IT will kill Cicada Killers that come into contact with treated areas for a sufficient amount of time to receive a lethal dose. It is labeled for non-edible trees and shrubs. You will need to dilute 1 fl oz of Bifen IT per gallon of water and broadcast spray over the areas where you have noticed activity. Most folks notice only very limited results from broadcast sprays of insecticides for cicada killers because they don't land and walk around for a long enough time before entering their underground burrow. Please read below for the most effective treatment method:
Cicada Killer wasps thrive in disturbed environments, such as landscaped yards and places where bare soil is exposed. You can discourage the wasps from nesting in your yard by cutting your grass on the highest setting and by adding a thick layer of mulch to flower beds during the Cicada Killer Wasp season. These wasps do not like over saturated lawns either, so over watering during their season will help prevent them. Unfortunately, there is no fool proof way to prevent cicada killer wasps. For prevention, you can try to use a granular insecticide such as Talstar PL Granules in the couple of weeks before this pest is known to emerge. For current infestations, you would need to use Delta dust in each individual burrow.
We also like to let our customers know that the Cicada Killer wasps are beneficial insects that provide free pest control for a couple months each year. Cicada killer wasps paralyze and provision their burrows with other insects to feed their young. The beneficial Cicada killer wasps, while large and intimidating to see, are mostly harmless and there have been very few reports of anyone getting stung by just being near them. In most cases where a sting was reported, the wasps were being held or molested in some way. Cicada Killer Wasp stings are also reported to be almost painless.
Bifen IT and Termidor should not be mixed for termite control. Bifenthrin products used to be considered a good form of termite treatment, but bifenthrin acts as a repellent and now a days almost all professional termite companies are using non-repellents, such as Termidor SC. We have a great article called How To Do A Termite Treatment that explains how to perform a treatment using a non-repellent termiticide.
Yes, Bifen IT can be applied and dried to areas indoors (that are listed on the product label) prior to the entry of your cats. The surfaces should be dried completely before they return.
Adding a surfactant to Bifen IT outdoors does help the product adhere and increase effectiveness during the residual period.

There is not an expiration date printed on the Bifen IT bottle. This product will last for 3-5 years from the date of purchase if kept sealed and stored at room temperature.
Yes, Bifen IT is labeled for silverfish and will do a great job helping to eliminate them. Be sure to spray in all of the cracks and crevices where silverfish are known to harbor for best results. You will mix 1 oz per gallon of water per 1,000 sq ft. and it can be applied every 30 days on the outside of the structure and every 90 days to the indoor cracks and crevices. Keep in mind that these pests frequent humid areas such as bathrooms and stored paper goods like files and wallpaper, so non-chemical steps to correct those conditions will help eliminate this pest.

We are not aware of any issues with using a bifenthrin product on St Augustine. This active is known for being super gentle on plants, so it should not harm it when used as directed on the product label.
Bifen IT is not labeled to control slugs. Slugs put down a continuous layer of mucus which makes it impossible for dried deposits of insecticide sprays to reach the actual slug. You will need to use a slug bait such as Sluggo Plus or Hi-Yield Improved Slug and Snail Bait to control the slugs.
If birds ingest enough insects that have been killed by Bifen IT, it can be toxic to them.
Bifen IT is labeled for stink bugs. You can use it indoors and outdoors but it is not labeled for use in a vegetable garden. We suggest using Hi-Yield Indoor/Outdoor Broad Use Insecticide with 10% Permethrin. It can be used on certain edible vegetation not grown for sale. Please take a few minutes to read the product label to see if the plants you need to treat are listed.
Bifen IT should be applied and dried prior to the entry of the dogs. Once dry, it is safe for their return. It will not reactivate when wet again.Your dog would have to eat a lot of grass most likely to get sick, and he/she would probably get much more sick from the grass then the product. However, of course we recommend anything you can do to minimize your dog from eating the grass.
