Short Review of Bifenthrin

Bifenthrin is a pyrethroid insecticide. Pyrethroids are synthetic chemicals modeled after pyrethrins, natural insecticides extracted from chrysanthemum flowers. Bifenthrin targets the nervous system of insects, leading to their paralysis and eventual death. When termites come in contact with or consume Bifenthrin, it disrupts their normal nerve functions. Termites then become paralyzed, leading to their death.

  • Broad Spectrum: Bifenthrin is not only effective against termites but also a wide range of other pests, including ants, roaches, and ticks.
  • Residual Activity: Once applied, Bifenthrin offers residual control, meaning it continues to kill pests that come into contact with treated areas for extended periods.
  • Low Toxicity: In comparison to other insecticides, Bifenthrin has relatively low toxicity to humans and pets when used as directed.


  1. Repellent Nature: Termites can detect areas treated with Bifenthrin and avoid them. This can result in termites finding untreated paths into your home.
  2. Not Always Effective Against All Termite Species: Certain termite species may show resistance or reduced susceptibility to Bifenthrin.

Short Review of Termidor

Termidor’s active ingredient is Fipronil. Unlike Bifenthrin, Fipronil is non-repellent, meaning termites can’t detect it. This stealth quality makes it especially potent. Termites that come into contact with or ingest Termidor become “carriers.” When these carriers return to their colony, they inadvertently spread the insecticide to other termites, leading to a domino effect that can wipe out the entire colony.

  • Transfer Effect: Termidors’ ability to be transferred among termites is a key advantage. This ensures that even termites that haven’t directly been in contact with the treated area can be affected.
  • Non-Repellent: Termites cannot detect Termidor, ensuring they don’t avoid treated areas.
  • Long Lasting: Termidor has a proven track record of protecting homes for over a decade after treatment, given that the barrier remains undisturbed.


  1. Specific Target: While Termidor is excellent for termites, it doesn’t have as broad a spectrum as Bifenthrin.
  2. Cost: Termidor treatments can be more expensive than Bifenthrin.

Product Comparison
Bifen XTS is known for its rapid action, this oil-based termiticide promises results within 24 hours by attacking the nervous systems of termites. While it’s strictly an outdoor treatment, its residual effect lasts up to eight weeks. A word of caution: its oil base could jeopardize plant life.

Termidor Foam stands out for its indoor usability. Its unique foam formula expands upon application, making it ideal for cracks and crevices. Moreover, it’s odorless, ensuring your indoor ambiance remains untainted.

The Verdict
When comparing Bifenthrin and Termidor, your choice may hinge on specific needs: If you’re dealing with various pests and not just termites, Bifenthrin offers a more comprehensive solution.

If termites are your primary concern, Termidor’s non-repellent nature and transfer effect gives it a notable edge. This ensures the product reaches the colony’s heart and offers longer-lasting protection.

Ultimately, the decision between Bifenthrin and Termidor will also depend on budgetary considerations, local termite species, and the advice of pest control professionals. It’s always wise to consult a pest management expert to determine which product suits your situation best.
