Fleas aren't dying because you're likely only killing adult fleas, while eggs, larvae, and resilient pupae remain hidden in your home, requiring consistent, multi-stage treatment (pets + environment) for weeks or months, as pupae wait for ideal conditions to hatch. Inconsistent application, environmental factors (heat/humidity), and neglecting hidden spots (carpets, bedding, under furniture) allow the infestation to restart.
Spot on treatments usually take longer than people expect, to work. The reason fleas do not die immediately is that there are still eggs and larvae on other surfaces such as carpeting, furniture, and pet bedding.
Regularly vacuum everywhere your pet has been
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.
A pale, empty abdomen suggests it has not fed recently and may be dead or long-lived without feeding. Use a white sheet or paper beneath the animal or area; groom a pet with a fine-toothed flea comb over the paper. Live fleas will jump or wriggle and may escape; dead fleas will remain motionless on the paper.
If you've already sprayed and if it did nothing, here's what might've gone wrong: Wrong product: Most over-the-counter sprays kill adult fleas but not the eggs or larvae. You need an Insect Growth Regulator (IGR) – this stops fleas from maturing. Try the Itch Flea House Spray for all households with fleas.
To kill fleas effectively, use a double action flea treatment that contains both Fipronil to kill fleas and (S) Methoprene to kill eggs & larvae too and break flea cycle, such as Itch Flea Treatment for Cats or Itch Flea Treatment for Dogs.
Itching and scratching
Fleas cause skin irritation from bites and nesting. You may be dealing with a severe infestation if your pets are constantly itching and scratching.

A flea infestation in your house can last several weeks to a few months, depending on how established it is and how consistently you treat it. Because fleas hatch in cycles, adult fleas may keep appearing. Persistent cleaning, pet flea treatments, and environmental control are needed to fully eliminate them.

If you're dropping your dog off for professional grooming, alert the groomer to the flea situation and he or she will use flea-removing products during the grooming session. Our flea shampoos also kill bugs, larva and eggs of dog lice.
Yes, fleas can live on the carpet. The carpet provides an ideal environment for fleas to hide, reproduce, and wait for a new host. Fleas lay their eggs on the host animal (such as a pet), but these eggs can easily fall off and end up on the carpet. As larvae hatch, they spin cocoons and develop into pupae.
Warmer weather is giving them a longer season with more bites, more risks, and more chances to spread into new areas.
Reapplying flea treatment after just 2 weeks generally isn't recommended unless specifically advised by an expert or vet. Most products are designed to last a full month, and overusing them could harm your pet. If the fleas aren't going away: Check that you applied the treatment correctly.
When a flea first emerges as an adult, it must find its first blood meal within one week or it will starve to death. After this first blood meal, non-reproducing female and male fleas may survive without feeding up to 4 days but egg-laying adult females will die within 24 hours without a blood meal.

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.
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.
