How to Eliminate Fleas

Wash your pet's belongings and sleeping areas. Put all of your pet's bedding into the washing machine and clean them thoroughly. These items include anything your pet likes to sleep on, not just their bed. Wash everything – bed linens, sofa throws, and even bathroom rugs.

• If the item is beyond saving, or if your pet's bed is full of dirt (pet dander, eggs, larvae, and flea feces), it's best to discard it and get a new one. Even if you wash the outer cover and rewrap it, flea eggs will still hatch.
• Fleas can also attack humans. If you suspect you are a victim of these bloodsucking pests, even if you're not, you should wash your bedding and mattress. Anything that frequently comes into contact with you could be a carrier of fleas and needs to be thoroughly cleaned.

Insect Growth Regulator (IGR) sprays like methoprene or pyriproxyfen. Room sprays are generally less effective than foggers unless they contain IGRs to prevent larvae from maturing into adult fleas. Without IGRs, larvae will remain uncontrolled as the spray won't reach the carpet base, where they develop.

Partner with a vacuum cleaner. Items suspected of carrying fleas can be washed, but you'll still need a vacuum to remove fleas from surfaces, crevices, and cracks. During this task, make sure to keep your pets out or confine them to the bathroom so fleas on them don't jump into the vacuumed areas.

• Place a flea collar or crushed mothballs in the vacuum to kill any pests you’ve sucked in, preventing them from returning. Fleas rarely survive a vacuum, but it's a good extra precaution.
• Focus on areas with less sunlight exposure (fleas favor cool, damp spots), especially where you find dried blood, flea feces, upholstered furniture, cracks around baseboards, and cupboard corners (where eggs and larvae may hide).
• Once the vacuum bag is full, seal it in a plastic bag and dispose of it in a covered trash can, ideally outside the home. Without this, the pests could crawl out and find another warm spot to hide.

Use botanical dust mixed with boric acid. Adult fleas only survive for about a week without a blood host, while larvae can live for months. Treat your home with safe, natural insecticides like a botanical dust mixed with borate to kill both adult fleas and their larvae.

• Botanical dust is one of the oldest natural insecticides. Borate is a commonly used mineral that works as a wood preservative, cleaner, and insecticide, and it’s toxic to fleas if ingested. It's safe for humans and can be used in environments inhabited by people.
• Although this botanical and borate mixture is quite safe, take care not to inhale it. Wear a mask when handling this mixture indoors.
• Vacuum carpets, furniture, bedding, and pet beds. It's best to do this when you plan to leave your home for a while, around 24 hours. Upon return, vacuum again, wash bedding and pet beds, or just wash the sheets and sprinkle more borate mixture on the carpets to prevent fleas from returning (this is a safe practice).

Clean up your backyard. Before letting your pets outside, trim bushes and grass so flea larvae are exposed to the sunlight. Take a look around. Do you see any dark, damp spots? Try to expose those areas to sunlight.

• Even if sunlight reaches these areas, your pet can still bring fleas back inside. The best solution is to use cedar shavings or eucalyptus leaves. Fleas detest these plants, and they're completely natural, so they won't harm nearby plants (or beneficial insects), nor pose a risk to your pets.
• Buy cedar shavings from convenience stores and spread them over flea-infested areas. If your dog is okay with it, sprinkle some inside their crate. You can also apply eucalyptus oil to flea-prone areas. If you're up for it, you could even plant eucalyptus bushes, though they can grow vigorously and affect surrounding plants.

Fill a shallow bowl with water and dish soap. This can be used as a homemade flea trap. The soap and water mix forms a deadly pool for the fleas, who are attracted by light and end up trapped.

• Pour the soapy water into a shallow bowl and place it close to the ground so fleas may unknowingly jump into it. An old, small flying saucer or a shallow bowl works well.
• Place the bowl near a low-hanging light, preferably brighter than a night light. Fleas are drawn to the light; after a few days, you'll find the bowl filled with their remains.

Use one or two dehumidifiers depending on the size of the room. A room measuring approximately 4x4 meters requires a dehumidifier with a capacity of 10 liters/day (which can remove up to 10 liters of water from the air daily). Fleas seem to need humidity levels of 50% or higher to survive. Keep the room's humidity under 50% for two days to kill adult fleas and larvae, while also preventing eggs from hatching. Simply use a vacuum cleaner to remove flea remains and their eggs.

Be cautious when selecting flea treatment shampoos. Traditional insecticides (such as pyrethrins, permethrin, d-limonene, chlorpyrifos, or carbaryl) can be irritating or harmful to both pets and humans. Instead, consider using natural insecticides or flea repellents that are safe for pets but harmful to fleas. However, it’s important to consult your veterinarian beforehand. Here is a list of insecticides and irritants that you might want to consider:

• Rosemary essential oil
• Eucalyptus essential oil
• Citrus peel essential oil
• Cedarwood essential oil (toxic to cats)
• Tea tree essential oil (toxic to cats) and can cause poisoning in dogs if ingested. If you have pets, this is something you should avoid!

Start by bathing your pet’s neck. This will prevent fleas from jumping to the head during the bath.

• When fleas come into contact with water, they will immediately seek dry areas on your pet’s body to hide. Therefore, if you can’t clean the entire body yet, at least wet the areas around the tail, ears, eyes, and neck before proceeding with the rest of the bath.
• For better results, lather your pet with soap and leave it for 15 minutes. 5 minutes is the minimum required to kill fleas, but 15 minutes is the most effective.
• Rinse your pet with warm or slightly lukewarm water for a few minutes, ensuring that the soap is thoroughly washed out and the areas where fleas may hide are soaked properly.

Use flea control products. These products can include flea collars, topical treatments, or oral medications. Topical treatments with higher concentrations, usually requiring a prescription from a veterinarian, are often the most effective.

• If the flea collar contains only an insect growth regulator (which prevents larvae development but does not affect existing fleas), use it alongside another treatment, such as a topical solution, to tackle adult fleas. Flea collars can sometimes be uncomfortable for pets and may not always work as expected.
• The following products are considered ineffective: Vitamin B1 supplements (thiamine hydrochloride), herbal flea collars, and ultrasonic devices.

Use a specially designed fine-toothed comb to remove fleas. Fleas are covered with tiny hairs that help them cling to the host's fur. Using a comb with teeth fine enough to trap the fleas is the most effective way to remove them. Other types of combs or brushes are often inadequate for fully eliminating fleas.

Mix 2 liters of warm water with 240 ml of vinegar. Add a small amount of mild dish soap.

Rub the mixture onto your pet's body. Add more dish soap if necessary. Massage the mixture into your pet for about 15 minutes.

Use warm water and a plastic scoop to rinse off the soap from your pet's body. Fill the scoop with water from the tap and check areas where soap might still be present.

Squeeze excess water from your pet's fur. Spray or pour vinegar on areas where fleas are concentrated.

Use a dry bath towel to wipe down your pet. Gently stroke them and apply flea treatment.

Baking soda works quickly and is affordable. If previous treatments have failed a second time, baking soda can be your house's savior.

Try using dish soap. Lather a generous amount of strong dish soap onto your dog. Let it soak for 5-10 minutes (or longer), then comb out the flea remnants. Rinse your dog thoroughly and let them dry. Dish soap also helps to make your dog's coat soft, shiny, and fresh-smelling.

• Ensure you rinse thoroughly to avoid drying out your dog's skin.
• Be aware that some dogs may be sensitive to strong soaps, so if your dog shows signs of an allergic reaction, rinse them thoroughly with cool water and try using baby shampoo after their skin returns to normal.

Use yeast as a weapon. Fleas are believed to dislike the scent of yeast. Although this hasn't been scientifically proven, many people swear by it. Purchase some brewer's yeast or nutritional yeast and rub it onto your pet's skin. You can also sprinkle a small amount onto their wet food and mix it in.

Make your own herbal flea bath solution. Take 2 cups of fresh rosemary leaves and add them to 1 liter of water. Boil for 30 minutes. Strain the leaves and add 3.8 liters of warm water. Pour this mixture over your pet's body until they are thoroughly wet. Do not rinse; let them air dry.

Sprinkle salt on your carpeted surfaces. Salt is a drying agent, meaning it absorbs moisture and dries out whatever it touches. When you sprinkle salt over fleas, the salt crystals attach to them. The salt will rub against the fleas and cause them to bleed to death as they move.

• Use fine salt. The finer the salt, the better it will stick to the fleas.
• After 7-10 days, vacuum the salted area thoroughly to ensure all salt and flea remnants are removed. Repeat this process one or two more times.
• Once you're done vacuuming, replace the trash bag in the vacuum with a new one. Tie the bag securely in a plastic bag and dispose of it outside your home.

Make a lemon spray solution. Slice a lemon into thin slices, add 500 ml of water, and bring it to a light boil. Let it sit overnight, and in the morning, pour the mixture into a spray bottle. Spray on areas where you suspect fleas may be lurking (be careful not to stain surfaces). Be sure to rub it into your pet's fur. Do not soak them; just dampen the fur. Perform this treatment once a month as a flea prevention measure.

• Another way to make a lemon spray is to buy essential oils (available in natural food stores); you can purchase a bottle of lemon essential oil and add 10-20 drops for every 30 ml of water.
• Only do this during warm weather: add 2-3 drops of the lemon mixture under your dog's collar to repel fleas.

Consider using diatomaceous earth. Diatomaceous earth is an affordable, easily accessible powder that is effective in killing fleas and most insects when sprinkled on carpets and around the home.

• Diatomaceous earth is classified as food-grade, meaning it is safe for both humans and animals if ingested. It works by puncturing the exoskeletons of insects, causing them to dehydrate and die.

Keep maintaining the process. This is the most crucial step, as if you neglect it, all your previous efforts will be in vain. Flea eggs that survived will hatch, and the entire cycle will restart. You need to follow these steps until there are no signs of fleas on your pet or in your home:

• Vacuum thoroughly twice a week. Fleas can develop resistance to insecticides, so frequent vacuuming is essential to keep them under control.
• Regularly trim the grass.
• Wash your dog's bedding with soap and hot water once a week.

Wash your car. While cleaning your home, don't forget to wash your car as well. Even if your pet isn't in the car, fleas can hitch a ride on your shoes or clothes. Pick up any trash and put it in a plastic bag, tie it up securely, and dispose of it.

Wash blankets and covers. Be sure to wash them with hot water and dry them at a high temperature.

Spray the interior of the car with flea repellent spray. Pay attention to corners, edges, the gaps between seats, beneath the seats, and the carpeted areas on the floor. Wait for 30 minutes before wiping the spray off.

Thoroughly vacuum. Just like before, focus on corners, edges, and gaps between seats, under the seats, and on the carpet. Make sure to empty the vacuum cleaner after use, as flea eggs sucked up could hatch later on.

Use a flea-repelling air freshener spray. Choose a product that leaves a lasting effect on the carpet. Lemon, eucalyptus, and cedar essential oil sprays effectively repel fleas while leaving a fresh scent in your car.

• Consider using a professional cleaning service to handle everything at once.
• If your dog plays with other dogs, notify their owners about the flea problem so they can address it early before it becomes a larger issue for them.
• Another effective product available at your vet is a pill containing spinosad, taken once a month. A few hours after ingestion, this chemical starts to kill fleas by poisoning them as they feed on your dog's blood.
• Place a cup of water mixed with dish soap on a table. Drop fleas into the mixture when caught, and they will sink and drown. (Dish soap breaks the surface tension, preventing fleas from floating on the water.)
• If (S)-methoprene doesn't solve the problem, your best bet is to visit the vet for professional flea treatment.
• (S)-methoprene is a common topical flea treatment. It works best when applied to a dirty dog, as the natural oils on the animal's skin act as a carrier. Be aware that fleas have developed resistance to (S)-methoprene in several areas of the U.S., particularly in Florida and California. If (S)-methoprene doesn't work, try a mixture of imidacloprid and permethrin combined with IGRs (insect growth regulators) like pyriproxyfen or methoprene. A common recommendation for this product is to avoid bathing your pet for 2-3 days after treatment.
• Carbaryl powder is an insecticide that can kill and prevent fleas when sprinkled on the lawn. It should not be used indoors or on pets.
• Nitenpyram kills fleas quickly. If you notice fleas on your pet, give them a nitenpyram pill, and you'll see the fleas fall off within 30 minutes. It's highly effective!
• One of the best home remedies is to add 2 drops of apple cider vinegar to your pet's water and spray the solution around the house. While the vinegar has a strong scent, it can eliminate fleas, and the smell dissipates quickly, blending into the air.
• For cats, citrus essential oils and lemon juice solutions are gentler alternatives to other home remedies.
• If using a spray indoors to eliminate fleas, ensure all open flames or ignition sources are turned off, as there is a risk of explosion in your home.

• Never use tea tree oil, cedarwood oil, or citrus peel oil for cats. Always consult a veterinarian before applying any topical medication. Tea tree oil is toxic to cats and is not recommended by veterinarians. It can also be harmful to dogs if ingested!
• Be sure to read the instructions carefully when using chemicals.
• If you opt for (S)-methoprene and it comes into contact with your hands, make sure to wash them as a precautionary measure.
• Ensure that everyone washes their hands before eating, especially children. If you ingest fleas infected with tapeworms, you may also contract tapeworms.
