Approximately 96% of fleas will be killed within the first 6 hours after application and the treatment will remain effective after bathing and swimming.
First Shield Trio also repels and kills ticks that can cause Lyme disease, erlichiosis and anaplasmosis.
What Are Users Saying?
Customer reviews of this product are mixed. Many users love First Shield Trio and claim that it’s the best flea product that they’ve ever used while others claim that it doesn’t work at all. The biggest concern though is the fact that it’s toxic to cats and has some disturbing side effects reported by a small but significant portion of small dog owners.
Reported side effects include itching, muscle spasms, lethargy, loss of appetite, drooling, seizures, vomiting, diarrhea, labored breathing, lack of bodily coordination, elevated temperature and even in a few rare cases, death.
Reviewers who have noted these side effects also reported needing to take their pet to see a veterinarian after the side effects continued or worsened. A few pet owners reported that their veterinarians classified these symptoms as an allergic reactions, while others were identified as poisonings.
Reviewers did note that the product’s applicator is easy to open and handle. Each package includes calendar stickers for owners to be used as a reminder for tracking when their pet’s next dosage is due to be applied. A minority of reviews were found to be in favor of this product, and these pet owners felt that the product worked well, was sold at a reasonable price, and did not cause any detrimental side effects.
Several reviewers report that their pets experienced a permethrin poisoning as a result of applying First Shield Trio. A number of pet owners have also complained that while their pet did not experience any side effects, the product was not effective and did not prevent flea infestations. It is also important to note that the ingredient permethrin is toxic to cats, and First Shield Trio should not be applied to or come in contact with cats. The First Shield product line offers a separate treatment specifically designed for flea treatment in cats.
Overall, while First Shield Trio did receive some good reviews, it appears that it’s hazardous to cats and possibly small dogs and its health risks may outweigh any positive feedback, at least for that population.
