Talstar P (bifenthrin) is one of the most popular broad-spectrum pest control concentrates — effective on a long list of insects and valued for its long residual. For termites specifically, know one thing up front: bifenthrin is a repellent pyrethroid, so termites tend to avoid treated soil rather than carry the chemical home, which makes it less ideal for colony control than non-repellent fipronil.
Key Takeaways
- Broad-spectrum and long-lasting — a genuine workhorse for general pest control.
- Repellent, not non-repellent — for termites it forms a barrier they avoid, rather than a colony-transfer treatment.
- Better as a perimeter/prevention barrier than as an active subterranean termite cure.
- For an active termite colony, a non-repellent like Termidor or a bait system is the stronger choice.

Ingredients
About 7.9% of Talstar P consists of a synthetic pyrethroid ingredient called Bifenthrin, which gives it the power required to act as a solid pest control agent.
The rest of the 92.1 % of Talstar P is made up of various chemical ingredients, which give it the ability to deliver a powerful knockdown effect. Like all synthetic pyrethroids, Talstar P works by attacking and harming the chemistry of the insects’ central nervous system, which causes paralysis and eventually death.
The unique thing about Talstar P is that the formula is available in three different forms: a liquid concentrate spray, an aerosol spray, and a granular dust form.
Manufacturer
FMC Corporation, an American Chemical Manufacturing company, manufactures Talstar P. This chemical company has made pesticides, insecticides, and fungicides to help farmers cultivate their lands more efficiently.
What Costumers have to say about the product?
After interviewing a few users of Telstar and doing some meta-analysis on current reviews available on different marketplaces, we found that most customers using Telstar P seem happy with the product results and have reported no major issues with its use.
However, there is a single report of an allergic reaction to the insecticide, but only if a person is already afflicted with a sinus problem. ( You should take this with a grain of salt. Every person is unique and you should read the label before applying to make sure you are safe)
Hence it is advisable not to use the insecticide product spray around people with a sinus problem as it can be dangerous to inhale it.
Talstar not only eliminates the insects in your house but also works as a prevention from any further infestations.
Never spray the product on couches, beds, and mattresses, as it may cause poisoning, especially in children and people with a low immune system. It is safe when dried but still, it may occur, as mentioned in the directions on the label.
Talstar P also eliminates termite infestation. It can also prevent termites from infesting your house. It stays in the soil for a longer period of time that is 3-5 years repelling termites.
Application
You can read much information about its application and precaution on the label.
According to the man, Talstar P formula as a liquid spray or via a fogger will give the most efficient results against pests. Talstar P does not harm vegetation; therefore, it is safe to use in lawns and gardens; however, it can indirectly harm human health when people consume the fruits and vegetables from the garden.
Therefore it is advised not to spray the insecticide directly onto edible fruit and vegetable plant body.
Talstar P protects against various pests such as Stink Bugs, Bed Bugs, Scorpions, Spiders, Mosquitoes, Cockroaches, Ticks, Fleas, Pillbugs, Chinch Bugs, Earwigs, Millipedes, Dichondra Flea Beetles, Spittlebugs, and others.
The steps required to prepare a Talstar P liquid spray are as follows:
- Wear safety gear like gloves, goggles, and a facemask before handling Talstar P.
- Fill the sprayer with half a gallon of water. If you don’t have one, try:
- Measure 1 oz. or ½ oz. of Talstar P, depending on your treatment, using the bottle measuring device itself.
- Pour it into the sprayer.
- Fill the rest of the half gallon in the sprayer and let it absorb for some time.
- Spray the chemical in desired locations.

When to call a professional
For subterranean termites — the kind behind most home damage — DIY products have real limits. Real control means treating the soil deeply and evenly (often drilling through concrete) or running a properly monitored bait program, which consumer tools can’t match. University extension services broadly recommend a professional for an active subterranean infestation. Use the products here for spot treatment, prevention, and accessible wood — and bring in a pro when the structure is at stake. See bait stations vs. liquid treatment for the full picture.
