Yes, Simparica Trio effectively keeps fleas off dogs by killing them rapidly (within hours) and preventing them from laying eggs, thus breaking the flea life cycle and controlling infestations for a full month. It's a monthly chew that also protects against ticks, heartworm, and intestinal worms, making it a comprehensive parasite preventative. Even with treatment, you might still see some fleas because dormant pupae in the environment can hatch, but the chew stops new adults from developing and infesting your dog.
Simparica Trio is the first FDA-approved monthly chewable that protects your dog against heartworm disease, ticks, fleas, roundworms, and hookworms. Simparica Trio does the work of two or three parasiticides in a single chewable by combining three proven ingredients.
In response to your question, yes, dogs can get fleas while on Frontline if the environmental burden is very large. In other words, sometimes the premises is so infested with fleas that the dog will continue to get reinfected before the Frontline does it's job.
*Please note that Simparica Trio does not cover for whipworm, which needs to be treated with an allwormer - so if you purchase a 3 pack of Simparica Trio, you will recieve a single dose of Cazitel (intestinal allwormer) that lasts for 3 months.
Simparica starts killing fleas within 3 hours, with a complete kill in 8 hours after treatment. It will give fast relief from itching and scratching, even in dogs with flea allergic dermatitis.
Seeing adult fleas unfortunately means there will be flea life stages (eggs, larvae and pupae) around the place, waiting to develop into new fleas. So, it's time to get busy with that vac wherever your pets go. Hard floors, furnishings, the car, carpets and rugs – they all need doing.
So, even if the treatment kills all fleas on a pet within 6 - 24 hours (depending on the speed of kill of the product you're using), the next day new fleas could jump onto the pet. As new arrivals, the clock is reset, meaning this fresh batch of fleas will themselves take up to 6 - 24 hours to be killed.
Both products are safe for dogs when following directions and have been approved by the FDA to treat and prevent flea and tick infestations. While Simparica was trialed and not approved, Nexgard has not yet been evaluated for use in breeding, pregnant, or lactating dogs.
There are several oral prescription flea and tick medications that are safe for dogs. These preventatives come in pill and chew forms. Your vet can help you find the right one for your pup's age. Credelio Quattro is an excellent choice for flea and tick protection.
Veterinarians may recommend Simparica Trio, a monthly chewable tablet that prevents against heartworm, fleas, ticks, and intestinal parasites.
You can completely eliminate a flea infestation at a specific point in time, but fleas can always find their way back if your pet is unprotected. With consistent treatment, proper cleaning, and preventative care, you can keep your home flea-free and stop minor issues from turning into full-blown infestations.
Flea season starts in May and runs all the way into the winter when temperatures begins to drop below freezing. The worst time of the year is during late summer to late fall, from September through November.
Capstar (Nitenpyram) — Instant Flea Killer for Pets
This oral medication starts killing adult fleas within 30 minutes and wipes out the entire infestation on your pet in a day.
Fleas may become more visible immediately after giving a product as they become agitated from the treatment. Most dog flea products kill fleas when they bite rather than repelling them, so owners may continue to spot fleas as they jump onto the dog or even people in the home.
Simparica kills both fleas and ticks, while Frontline Plus is effective against fleas, ticks, flea eggs and larvae and lice. Simparica kills fleas within 3 hours and kills ticks within 8 hours. Frontline Plus kills fleas within 12 hours and ticks within 48.
Sarolaner (brand name Simparica®) is used to treat and control flea and tick infestations in dogs. The dog ingests sarolaner, and the drug is distributed throughout the dog's body. When fleas or ticks bite the dog, they are exposed to the drug and killed during their blood meal.
Popular, vet-recommended flea and tick medicines for dogs include chewables Simparica and Credelio, plus Bravecto topical, all of which are prescription medicines. Your vet can help you choose the best flea and tick medication for your individual dog based on their specific needs.
To prevent fleas on your pet:
Dogs can also become exposed at toxic quantities through the ingestion or absorption of household insect sprays, foggers, and granules. Common brands of pyrethrins/pyrethroids include: Advantix™ Vectra 3D®
While Simparica Trio is generally effective in protecting dogs from fleas, no medication offers 100% protection at all times. Variations in individual response, incorrect administration, or a particularly heavy flea presence can reduce effectiveness.
When considering time to efficiency between these two, we'll consider it a tie. Both products are safe for dogs when following directions and have been approved by the FDA to treat and prevent flea and tick infestations.
Simparica Trio™ has not been evaluated in dogs that are pregnant, breeding or lactating. Simparica Trio™ has been safely used in dogs treated with commonly prescribed vaccines, parasiticides and other medications. Use with caution in dogs with a history of seizures.
To kill 100% of fleas, you need a multi-pronged approach: treat your pet with vet-approved products, thoroughly vacuum and wash all bedding, use effective indoor sprays with an Insect Growth Regulator (IGR) to stop the life cycle, and consider professional pest control if the infestation is severe, as consistency in cleaning and treating for several weeks is key to breaking the cycle.
They can wait patiently for weeks, even months, especially in cooler temperatures, for the right triggers (like vibrations from footsteps or warmth) to emerge as mature fleas. Given these stages and environmental conditions, fleas can survive in your carpet anywhere from 2 weeks to 6 months.
Vacuuming can kill adult fleas instantly, but eggs and pupae may survive. Plan on vacuuming daily for at least 3 to 6 weeks to break the life cycle and stop new fleas from emerging. Always empty the bag outside after each use to prevent reinfestation.
