βš—οΈ Mixing & Dilution Guide

Rates below are general guidelines. Always follow your specific product label β€” rates vary by brand and application site.

Termite soil treatment (trench & treat)
0.8 fl oz / gal (0.06% solution)
4 gallons per 10 linear feet per foot of depth. This is a professional application in most states β€” verify your state license requirements.
Ant perimeter spray
0.8 fl oz / gal
Apply to soil and structure perimeter. Taurus SC is a direct substitute for Termidor SC at identical rates β€” same active ingredient, same concentration.
Indoor crack & crevice (Phantom)
Ready to use aerosol
Apply directly to harborage areas. Fipronil has a 'transfer effect' β€” insects carry it back to the colony.
