You can eliminate most adult fleas within 24 to 48 hours, but completely eradicating an infestation takes 3 to 6 weeks. Because fleas have a complex life cycle, eggs and pupae can continue to hatch over several weeks.
To get rid of fleas in 24 hours, you must target the 5% living on your pet and the 95% in your home simultaneously. Use a fast-acting oral tablet on your pet, vacuum and treat carpets with salt, and set up overnight soap traps to quickly knock down the active population.
Fleas have a complex life cycle. At some stages of their life cycle they are resistant to insecticides and other flea control products. In order to get rid of fleas in all stages of the life cycle, two or more follow-up treatments within 5-10 days after the first application are needed.
Fleas have highly sensitive sensory systems and strongly dislike strong, herbal, and citrus scents. You can use these natural deterrents to keep them away from your home and garden, though they will not completely cure a severe infestation.
To completely eliminate a flea infestation, you must break their life cycle by treating all pets, your home, and your yard simultaneously. Because 95% of the infestation lives in your environment (eggs, larvae) rather than on your pet, consistent daily cleaning is just as important as chemical treatments.
Fleas will not go away on their own. Since up to 95% of an infestation lives in your carpets, furniture, and environment as eggs and larvae, you must break the life cycle by treating your pets and deeply cleaning your home.
Natural methods that kill fleas instantly on contact include bathing pets with Dawn dish soap and using a flea comb dipped in soapy water. For home infestations, high-heat washing of bedding (above 120∘F) and vacuuming are highly effective.

How to Use Natural Predators Against Fleas, Flies and Cockroaches
Fleas are incredibly hard to squish because they are built like tiny, microscopic tanks. Here is why they survive your fingers:

To eliminate fleas fast overnight, you must simultaneously kill the adults on your pets and treat your home environment. Use a fast-acting oral medication like Capstar on dogs and cats, and apply a household spray or salt treatment to carpets and furniture.

In the 1800s in the 1900s sulfur was used, especially for bad infestations. Also, what we now usually call a comb or hair comb, was for centuries known as a " lice comb ".
Fleas jump into soapy water because they are naturally attracted to the warmth and light of a nearby heat source or lamp. Once they jump toward it, they fall into the bowl and drown because the dish soap breaks the water's surface tension, preventing them from floating or escaping.
Getting rid of fleas requires treating your home, your pets, and your yard simultaneously to disrupt their complex life cycle. Vacuum every day, wash all bedding on high heat, treat your pets with veterinarian-approved medication, and apply professional indoor sprays to eliminate the infestation.
Fleas can occasionally survive a washing machine if the water temperature is too low or the cycle lacks the proper amount of soap. The combination of hot water (at least 60∘𝐶/140∘𝐹), heavy-duty detergent, and the agitation in the dryer is the most effective way to eliminate fleas and their eggs.
Fleas can live in your house for anywhere from a few weeks to up to 5 months or more. Their lifespan depends heavily on their life cycle stage and whether they have access to a host (like a pet or rodent) to feed on.

Fleas are generally the worst from July through October. They thrive in warm, humid weather and reach their absolute peak during the late summer and early autumn months when temperatures consistently sit between 70∘F and 85∘F.

Fleas have been associated with humans and other animals for thousands of years. A bacterium (Yersinia pestis) spread by fleas killed 25 million people, more than a quarter of the European population, in 14 th century Europe.
To get rid of fleas in the house quickly, treat your pets with a fast-acting tablet like Capstar or a flea bath to kill adult fleas, then provide a long-term flea preventive. Vacuum daily, wash bedding in hot water, and use flea sprays or powders on carpets, furniture, and the yard.
Also heard Head and Shoulders shampoo works well! Dawn dish soap kills fleas on its own. Just doesn't kill the eggs. Mary Junkin Black add a 1/2 tsp table salt - it kills the eggs, rinse extra well.
Flea eggs are best killed using Insect Growth Regulators (IGRs) (such as methoprene or pyriproxyfen) found in household sprays, high heat (hot water laundering or steam cleaning), and physical removal via daily vacuuming.
