Christabelle from Pembroke Pines writes
Fipronil is a non repellent that has a transfer effect. This means that termites and other insects are not able to detect it and as they go across a treated area, they will pick the product up and can carry it back to spread to others in the colony. Bifenthrin is considered a repellent in that insects can detect it is there and may try to avoid the area, it also will only kill those termites that contact a treated area directly or that are sprayed directly. Also depending on where you are applying it residual can vary with Fipronil lasting up to 10 years or more in the soil when applied in a trench and Bifenthrin only lasting about 5-7 years.
