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 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.

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.

Please take a few minutes to read the product label to see if the plants you need to treat are listed.
