To kill flea eggs on cats, use veterinarian-approved topical or oral treatments containing Insect Growth Regulators (IGRs) like lufenuron (e.g., Program) or topical treatments with methoprene/pyriproxyfen (e.g., some Advantage, Revolution), which stop eggs from hatching, combined with rigorous cleaning (hot washing bedding, vacuuming daily) and potentially hot water baths with flea shampoo to eliminate them physically. Always consult your vet for the safest, most effective cat-specific products, as dog treatments can be toxic.
You can use a flea comb and a bowl of hot water with a bit of soap in it. Comb out the eggs and rinse the comb in the soapy water to make sure the eggs die.

Fleas cannot be killed instantly. However, the fastest home-safe method to flea murder is by drowning a flea in chemicals. Dish soap, herbal flea spray, saline, and fresh lemon juice are all highly effective.
Baking soda does not kill adult fleas and will do nothing to protect your pets. It is excellent at absorbing smells and has been suggested by some online pet sites for use as a flea killer because it “may” dry out flea eggs and larvae. But there is no evidence that using baking soda to kill fleas is effective at all.
The comb can also help to remove eggs from your pet's fur. Apple cider vinegar can't kill fleas, but it can help to repel them. Fleas don't like the smell or taste of it, so they're likely to avoid your pet if they have it on their fur. Dilute apple cider vinegar in water and add it to a spray bottle.

Flea Repellents For Pets
Dilution is Key: Essential oils like lavender, cedarwood, or eucalyptus can repel fleas, but they must be properly diluted with a carrier oil (such as coconut oil) before applying to your pet's coat. Direct use of undiluted essential oils can irritate their skin or even be toxic.
The methoprene and pyriproxyfen-impregnated collars are virtually 100% effective at preventing new flea eggs from hatching for at least 6 months (essentially season-long) on both dogs and cats.
An adult female flea lays hundreds of eggs that are designed to fall off the host (cat) and into the environment.
So, yes, one flea can—and often does—become a problem. Flea eggs usually fall off your pet and land anywhere your pet spends time: carpets, furniture and in bedding. If your pet sleeps with you, fleas could end up on your bed as well. In only a few days, these eggs hatch.
Can fleas live in litter boxes? Although adult fleas would much prefer a living host, it is possible for them to live for several days in unexpected areas of your home, such as the litter box. Flea eggs, meanwhile, can also survive the 1 to 10 days it takes for them to hatch in the humid environment of cat litter.
If your cat comes into contact with another cat who has fleas, the fleas are likely to jump onto your cat. They then come home, where the flea will lay its eggs and more will hatch. They can also easily pick up fleas in places like catteries or the vet, or even off any rodents they might chase while out and about.
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.
Adult fleas themselves are noticeable as fast-moving, tiny black insects. If you suspect your cat has fleas, the first place to check is the skin around the base of the tail or under the armpits and in the groin region. Look for tiny, moving black dots. Indoor cats are just as susceptible to fleas as any other cat.
Flea eggs can be killed instantly with heat, such as washing them in hot water (above 60°C), or by using specific insecticidal sprays designed for flea eggs. Flea foggers or flea bombs may also help target eggs, though they're not always 100% effective.

No, fleas cannot establish permanent colonies in human hair. They prefer animal fur and typically jump off humans within 24 hours. Human hair lacks the density and warmth that fleas need for reproduction and long-term survival.
Comb your pet with a flea comb, not just a regular comb!
Flea combs are more narrow and are designed to catch any pesky fleas. Be sure to dip the comb in hot soapy water frequently as you comb. Fleas and eggs might stick to the comb, so dipping it in dish soap and water will rinse them off.
Leave the mixture of salt and baking soda on the carpet overnight. The solution works by dehydrating the fleas and eventually eradicating them. Then, vacuum the carpet thoroughly to get rid of dead or dying fleas. Repeat the process every three to four days, as flea eggs hatch within this period.
