For fleas in dogs wash them with boric acid powder or Head and Shoulders. Use white vinegar in the water just a little. Sprinkle Earl Grey Stash tea and fleas will run dogs love it could be the reason they roll in it!

EC: Boric Acid can be toxic to dogs.' Read more about this on our Mange page.

Be careful with Brewers Yeast for Fleas. I started giving it to my two dogs a few years ago and after a couple of weeks, both dogs were scratching like mad. I thought they had fleas but couldn't see any. I Googled Brewers Yeast and found that many dogs have a bad reaction to it.

Sprinkle borax on carpets and sweep it in with a broom. It is dehydrating and kills fleas. Harmless for dogs, even if they lick it some. It is actually good for them in very small quantities. It helps with arthritis. Look it up here and/or look up Walter Last and borax to read more about it.

I give my dogs brewers yeast and garlic tablets.1 tablet for every 5 lbs.They love them,eat like treats.I have mini dachshunds from 3 months old to 2 years old. No fleas or worms. Garlic kills the worms and brewers yeast is good for the skin.

Just a bit of warning about using garlic on dogs and cats.... They have found that onions are toxic to animals and galic is in the onion family so be very cautious of the amounts you give as you could be harming you dog and I would never give it to a cat.... Just fyi

I bought a bottle of brewers yeast at walmart for flea control as I read somewhere it might help.

It made my german shepherd so sick and he got an ear infection right away. I had to take him to the vets to get meds. The vet would not give me oral antibiotics, but gave me ear drops. I wish I had bought fish antibiotics and looked up the dosage from revival animal health or drs foster and smith for him. He ended up biting me really badly because he didnt want the drops put in his ear and I ignored the threat display to get them in his ear and he attacked me...not that it was his fault..he is a wolf hybrid german shepherd and he has a large set of teeth.

Never use brewers yeast for flea control it doesnt work and it causes illness.

ON the contrary, I have a big steel pot I use for all my animals water and every time I fill it up I put a cap ful of apple cider vinegar in it, the best kind is the kind at the health food store but I just use the kind at the dollar store, and it starts working in about two weeks. They dont even notice it is there and it cuts the yeast out of their bodies and the fleas dont really like the taste of it and I also mop with it and I love it for all it does!

For years I have used Brewer's Yeast until now and that is because it has been difficult to find it here in Puerto Rico. I used to buy it at Walmarts and Walgreens Pharmarcy but it has been discontinued. I have always used it for my dog and her hair is shiny, she is quite healthy. She is always outside and she loves to sleep on sand (major factor for fleas and ticks) and she has no fleas nor ticks. I have used it on all the dogs I have had. The ones that died were of all ages (15 yrs) but never due to anything they ate or that I gave them.

I wanted to add to this a little as well. Some dogs do have a high yeast count in their body's and giving them supplemental yeast could result in a yeast infection of the skin or ears. But as a general rule, brewers yeast is effective on flea prevention and is very safe for your dogs. If you are concerned that your dog might develop a yeast infection talk with your vet about assessing yeast levels on their skin before you begin.

Thank You so much for having this site !! I am having success in only less than a full day using Brewers Yeast against these invisible biting bugs , which I believe to be Sticktight Fleas, I have suffered with them for a year now. I am so thankful to be able to pass along what I consider VERY valuble information. I always knew somehow , the remedy would be something simple and common, Brewers Yeast has been used for decades ( maybe longer ) on all kinds of animals for fleas and moskitoes bothering people. I felt results within 15 minutes of taking it, you will feel them getting active in your flesh!! I slept last night , straight through for the first time in at least 8 months. Don't give up the Borax & DE in carpets though, it is also valuble in this battle, I will continue using 20 MT Borax in my laundry for some time. My prayers are with you all.

Brewer's Yeast works! I started using it early last spring, throughout the summer and into early winter. I never saw a flea on my Bassett Hound. I had my doubts living in a humid, hot climate where fleas thrive, but I never saw even 1 flea. I put about a teaspoon on her food at night (she's a small bassett, about 40 lbs). She loves the taste! Brewer's Yeast is natural and filled with other nutritional stuff your dog needs. Give it a try!

I had the worst flea infestation EVER, last year. I have two Dogs, and I live in Ohio, right near the lake, so the humidity here is terrible. The infestation was so bad, my 2 year old was getting bitten all over. I didn't know what to do. I tried ACV, in their water, and It didn't really improve anything. Although, I think I was a little impatient, I read that you have to wait 6 weeks for results. Tried Garlic, the kind you get in the jar in olive oil, AND powedered. Did not workat all.

Brewers yeast seems to be working well, so far. I started in March, now it is almost May. They are a lot better now then last year at this time. I also use flea collars, because, I have to do something aggressive for these dogs, they suffered so much last year. My German Shepherd actually liked off all of her hair on her hind side, and was bald. I used Tea tree oil, about a dropperful in some Castile soap for their baths last year, but this year, I'm planning on trying Neem Oil. I'm going to try rubbing it on their fur as a repellent as well. See how that goes. Wish me luck!!

We are getting ready to move to Washington state and I wanted to try and get a head start of protecting my dogs from fleas. I have a begale and 2 mini-dashunds and was wondering how much brewers yeast they should get? I bought tablets, but not sure if they should get the whole tablet (if so how often) or if it should get crushed up (and still how often) I already give they fish oil tablets 2x a week to help w/the dry skin that happens here. Also I'm seeing that my little ones don't care for the garlic powder on their food, will it be just as effective if it is cooked (say in biscuits)? Thanks for all the great advice on here! Glad I found this site!!!!

Hey, get the big jar, and sprinkle and coat it on their dry food like cinnamon toast. Mix it well, make sure all the dry food is covered. IT WORKS!!! All summer long, NO fleas, amazing. The only thing that works honestly.

Having problems with fleas on our dog. The vet said the dog was alergic to fleas. The liquid my daughter puts on his neck makes the dog sleepy. I am going to try apple cider vinegar and brewer`s yeast but what is ACV you talk about. Fran Lord

EC: ACV is short for Apple Cider Vinegar.

If ACV doesn't seem to work on fleas, try Brewer's Yeast vitamin tablets and cedar chips for bedding. Most dog beds have cedar chips inside them, but you can also buy them straight for dog houses and such.

Cedar Chips, Dish Soap

I have had dogs as pets for more than 50 years and they are inside pets, but are let out to a fenced area constantly during all year and I have found that at spring before the first mowing. I will go to Walmart and get 2 large 0.5 cubic ft bags of cedar chips or bedding and sprinkle it throughout the areas where the dogs will be. I do this before the first mowing and after I mow the yard it will scatter the chips even better and finer.
I never have fleas and to check occasionly, I will fill small bowls with water and a few drops of dishsoap , place them under a wall outlet with a nightlight on overnite and in the morning if there were any fleas in the house, they will be dead and in the bowls. I always do this ritual every year faithfully and never have a flea problem in my yard.

Use cedar chips as bedding instead of straw. Cedar is a natural flea repellent.

Replied by Ellie

I have to agree with Angie, Waverly, Oh. She recommended using cedar shavings instead of straw in a dog house. I bought catlitter cedar shavings and also used it to insulate my rosebush with it for winter. Surprisingly the following year for the first time my rosebush didn't have a bug anywhere on it or holes in the leaves as it previously had year after year. It is sold as catlitter and may be great to retard fleas and other critters too. Ellie

Two products from Cedarcide, out of Texas, work well. PCO to spray in the yard & Best Yet spray not only for your pets but, yourself & children.

It is cedar oil based & works wonderfully.

I forgot to mention that Cedarcide's Best Yet spray can be used on carpets, flooring, furniture. It does not stain. However, I do not think I would use it on silk or fine damask. I used it in a room with a 75 gallon salt aquarium, making sure the spray did not go into tank & nothing was harmed. The aroma of cedar does not linger for long.

Cedarwood Oil

You really ought to try cedar oil... Especially- there is a company that uses a special blend that is deadly to ALL exoskeleton type insects (and their eggs and larvae). I had a terrible 2-year infestation. Tried every home-grown remedy and commercial remedy on my dogs and in my home... Spent $100'S of dollars but the darn things were indestructible! After another day on the net, I decided to try a cedar oil based product (so safe I apply it to the SKIN of my 2 yr-old granddaughter as a repellant for fleas and mosquitos) One treatment of my home and dog the hopping, biting critters were magically gone. The stuff is fabulous I think when comes to fleas and bedbugs - IT IS INFALLIBLE! - Dr. John

I would like to know how to dilute the cedarwood oil so it can be applied to the skin as a repelent for fleas and mosquitos. Also what is the mixture of cedarwood for spraying the carpet.

Posted by Maxine (Havana, Arkansas, USA) on 11/13/2008

Not allowed to mention brand names. Do a search for cedarwood oil, there is a company in Texas and that is all they sell is Texas cedarwood oil. This stuff is a God send. It even kills bedbugs, headlice, fleas, ticks on contact. I have used many natural products for fleas , this is safe for even the youngest or pregnant animals. This stuff is only toxic to pests. Completly safe for humans. It smells good too. Got tired of toxic stuff on my 4 yorkies. It is all natural. One of there products is for soldiers in iraq , kills sand fleas. Also bugs can not get immune to this, unlike chemical products, bugs develope defences to. This is the only product I use for pests. I am not afilliated with this company in any way.

How much and how was this used??

Replied by T=Bone

The above-mentioned product, food grade aromatic Red Cedar Oil is combined with melted Quartz Rock, and comes properly and proportionally pre-mixed and needs no dilution, additions, or calculations. The company also sells spray bottles and fogger machines (or look for 2nd hand on online auction sites or local garden stores) for treatment of large indoor areas (this product apparently not good for plants or gardens). They provide suggestions as to how much is needed for covering the square-footage you wish to eradicate of fleas - I usually get a little more to have on hand for incoming fleas from the outdoors or other people's pets as well as to use as mosquito repellent for myself. It is anti-bacterial and non-toxic to humans and pets of all ages. I find the smell is great BUT pretty pungent, so your human and non-human cohabitants may not wish to be present during application or for several hours after; ventilation helps reduce the intensity allowing all to return later that same day to the now flea-free area! I am not in any way affiliated with this company but endorse their product fully.

This summer has been the worst for fleas. Have been fighting the critters for a few months on our lab and cocker. spot-on chemicals did nothing. I'm done spending money on monthly treatments and have read some of the research that is a bit scarey. I called the company of the one I recently used and was told, "the product works, your dog must be picking up new fleas daily. " So what good is it if they stay covered in fleas??? I am currently using the cedarwood oil I bought on line from a company in texas. It came with a 1oz. Spritzer you can refill from the jug. easy to use. It works as well as advertised, will kill a flea in seconds. We have used it frequently on the dogs with no harmful side affects. The only draw back is that it doesn't continue to work for any length of time. If the problem is bad, like ours has been this summer, the fleas return. But a heck of a lot cheaper and safer than spot on treatment. The 32 oz bottle should last quite a while. We've started a more aggressive approach with some of the ideas we found here, I. E. Brewers yeast, ACV, etc.. The cedarwood oil spray has worked well, but as you probably know.... the little critters tend to stay out of sight most of the time.

Just so you know.. "melted quartz rock" is actually petroleum distillates. Ie: paint thinner. I bought this product back in 2010 only to find this out when it arrived & I read the label. "Ingredients:10% Cedar Oil, 90% Petroleum Distillates. " Needless to say I was beyond disappointed.

For the past two years I have been using a wonderful natural insect repellent for my dogs. It is a completely natural product using Lavender, Cedarwood, Rosewood, and Patchouli essential oils in an organic base of olive oil, shea butter, and beeswax. The product is excellent and smells great.

Cedar is toxic for all animals - including humans. Breathing in the scent can cause/trigger asthma, Upper Respiratory problems, and more. It is especially toxic to cats. It is sold as litter and bedding - but SHOULDN'T be. It is commonly used for rodents for bedding. Those rodents live roughly HALF as long - as rodents who are not bedded on Cedar. All soft woods emit toxic chemicals in their essential oils. If you can smell the wood aroma - it is toxic. (Including Feline Pine Litter - which HAS killed some cats.) ALL essential oils are toxic to cats - to varying degrees. Cedar and Tea Tree Oils are ESPECIALLY toxic. If you research this info on the internet - it's hard to find - but it's there! (eg. search "Toxic effect of Cedar" or "softwoods" et al.

Flea and Worm Remedies: My dogs are 2 years old - a red healer and a pit bull. The pit had fleas really bad this year and got worms from the fleas and nothing seemed to work, even flea medication and the wormer. My dog became very irritated by the shampoo so i bathed him in ground up oatmeal, dawn and apple cider vinager, its been almost a week and the transformation is huge, i started giving him 2 tablets of brewers yeast and 1 tablet of fish oil a day since the day of the bath. He still had worms so I gave a clove of garlic yesterday. I'm stilll waiting for the results of that.
