Flea medication not working on pets

 To eliminate a flea infestation, it takes patience treating your pet and your environment.

All too often, a pet owner will come in and share their experience in which he or she regularly applies topical flea prevention, yet is frustrated that after several treatments they are still seeing fleas. There are several plausible explanations for persistent flea infestations which may have nothing to do with lack of efficacy of these products.

First, I make sure that the pet owner is correctly applying the flea medication. It is important to completely part the hair and apply the product directly to the skin so that proper skin and hair follicle distribution can occur. This is something that can be somewhat of a challenge for thick haired pets; however, the pet medication will not work properly if only the hair follicles receive the medication – it must be applied to the skin. It’s also important to properly follow product label directions, which may vary depending on the size of your pet. For instance, for large dogs, Advantage II requires the product to be applied on multiple spots down the pet’s back.

While it is tempting to try and save money by using only portions of products labeled for larger pets on smaller animals, it’s a process such as this that can lead to product inefficiency. Another reason for products not working is by not treating your home and yard, where in some cases 80% of the flea life cycle may occur. Read how to control fleas indoors and outdoors.

In cases of heavy flea infestations, some home products such as Richard’s Organics Premise Treatment can dry out or desiccate the various flea life stages. In spite of recent discussion in the veterinary literature, the development of widespread flea resistance is still not believed to be a major factor to clients still finding fleas on their pets.

Have you been battling a flea infestation in your home? What are some of the ways in which you have been trying to get rid of them?

  1. I can’t believe i found this wonderful site and people going through what I am going through. When I told my sister i was still vacuuming and spraying the house and treating the cat she said i was crazy and it was all in my mind. I have learned to shut up because everyone things i have gone mad. Last year, just around this time..the actual date I will never forget was December 14, 2016 when i awoken to bites on my body (and i had just had a heart attack) and then i got my cat and picked her up and there were thousands of fleas running across her stomach.. I ran her to the bathroom and grabbed dawn soap (I didnT’t know that was good but apparently it was)..This was on a Saturday. My son’s dog had been battling fleas and he had brought his dog to my house on numerous occasions and even one time showed me fleas on his dog. So i guess this was when they found a home in my house and got on my cat. nevertheless, i found live fleas running all over the bathroom; especially along the bottom of the toilet where the contractor had decided it didn’t look nice to caulk.. my son’s dog would take a shower with him, so i assume they found refuge in my bathroom. My son to this day declines to take responsibility for putting me and my cat at such a risk. So, they procreated in there and behind the new cabinet in my bathroom.. Anyway, i did the recommended protocol and went to the vet, (he wouldnt even look at my cat)…and recommended the seresto collar and I called an exterminator. Needless to say, the exterminator had very little experience in this situation and gave me very poor advise, did not tell me not to mop or any instructions.. The situation became so intense, i was bitten to death daily.. I also work from home so I have developed a severe flea allergy dermatitis as does my kitty cat. Anyway, I found another exterminator in March and have had the house done many times. I also found a wonderful site called do your own pest control who have professional exterminators help you do it yourself. I had to find another vet because i was at my wits end. The new vet said that Seresto collar had not been proven yet and took her off it and put her on Revolution and capstar. He should have told me not to remove the seresto collar for a few days bedause when i got home in March 2016..and took the collar off and put the revolution on..the fleas went crazy.. they were biting me. These fleas are so strong that they were able to jump over the shower and bite me while i showered. Anyway, it’s a year now and my real problem comes that I am going away and leaving the cat with a sitter. My vet said to dose er with revolution every 3 weeks and capstar. But the fleas are still around. I think they are at their last leg because i continue closely to monitor my cat to see if she has even a sign of a fleas,vacuum and dry swiff my floors to see what is still on them. I do not have any carpets, just wood floors, tile and moldings. But to be safe, and to ensure a cycle doesn’t begin or if I see any sign of flea dirt, I give a capstar. So, i plan to get the exterminator one more time in early December before I go away so they are not partied when i am gone. My question is, why do i still have fleas for so long with the cat on Revolution and the exterminator changing chemicals all the time. I do not have rugs, only wood floors and tiles, but….the contractor had put the floors down with about a 1/2 to1/4 space in the moldings and i think they have laid eggs there. They are also in my kitchen.. I haven’t cooked in a year because i have gotten bitten. The fleas have bitten my back while i work so all it takes is to be near a flea or flea matter and i am on fire. Anyway, do you think I should try something more drastic like changing from Revolution. I heard there is a topical form of comfortis, cheristin which i was wondering if I should try. My vet is wonderful and sells nothing else. The other Vet has something called Vectra for cats.. not sure if i should change it up now before I go away. She is due for her Revolution this Tuesday, so wondering if I should switch it up now? Try Vectra …I don’t go back to the vet who put her on Revolution because i called the office and the receptionist said they do not prescribe anything but revolutoin..So, the other Vet would sell me the Vectra. I need this vacation, but want my sitter to have no bites and the cat to stay flea free while i am away… Don’t want to cancel my vacation. I need it. Any advise.. I am trying so hard.. and have suffered so much.. and my poor cat has been so good through all this. I love her so much and want her to have a healthy life and don’t want her to be flea infested while i am away..

  2. If your vet feels it is appropriate, then cheristin is certainly a good product to try. Sorry to hear you have had so much trouble with the intense flea situation in your home. I did not find that vectra works as well as some of the others in my experience and opinion. Revolution is excellent as a preventative, but when you are over run like this it is best to use an additional product such as comfortis, etc.
