Why is My Flea and Tick Medication Not Working?

If you're providing your pet with flea and tick prevention like clockwork and they are still getting bitten up, check out a few reasons why your medication may not be working.

If you are routinely providing your pet with flea and tick prevention and they are still suffering from pesky bug bites, there are several reasons why your medication may not be working.

It's All in the Application

First and foremost, you need to make sure you are applying the medication correctly. We know this goes back to grade school basics, but always read the instructions. This is especially true when it comes to topical products such as shampoos, dips, or spot-on treatments. It is important to make sure the product reaches your pet's skin and doesn't sit above the epidermal layer under the fur. If the product doesn't hit the skin, it cannot be absorbed in your pet's sebaceous glands, where it works its flea-fighting magic. Also, make sure you are using the entire tube of medication. Don't skimp and try to save a few dollars by splitting the product between months or between pets. It will not function properly if you do so.

Healthy Skin is a Must

Your pet's skin could easily be affecting the flea treatment results. As mentioned above, if the product does not reach your pet's sebaceous glands, it will not work effectively. This is common in pets that have extremely dry and unhealthy skin or thick fur. When in doubt, a simple trip to the groomer will provide a world of difference. Similar to humans, it is important for your pet's skin to be exfoliated so extraneous dead skin cells are removed and the topical treatment can work properly.

Due Diligence

If your pet's skin is the picture of health and you follow medication instructions from top to bottom, you may need to add a second level of flea prevention in the form of a flea collar. Sometimes, in extreme weather regions where heat and humidity prevail, fleas are more common, and your pet may just need a little extra flea-fighting power. Flea collars are effective, hassle-free, and one of the only forms of prevention that can be combined safely.

Environmental Control

To banish fleas and ticks once and for all, we recommend treating your house and yard with preventative products to ensure an insect-free lifestyle. Oftentimes, if your yard is heavily landscaped or you live near a wooded area, it is smart to invest in flea and tick yard spray to add another level of insect security. This will give your pet even more protection from those pests.

Can Bathing My Dog Affect their Flea Treatment?

Believe it or not, being too clean can be a bad thing. For some people, that is an inconceivable notion while some other folks have yet to meet a pile of dirt they don't like. However, when it comes to proper preventative care for your dog during and before flea and tick season, hold the soap, for a little while at least.

Wait it Out

As a general rule of thumb, when applying any spot-on, topical, or at times even oral medication to your pet, it is best to wait at least 48 hours before bathing. In the case of flea and tick prevention, this allows the product to begin working effectively. This is especially true for spot-on treatments, dips, sprays, and shampoos. Spot-on treatments are applied directly to your dog's back and base of the tail. Within 12 hours, the product will begin to kill fleas, repel fleas, and ticks on dogs and continue to prevent infestations for up to a month.

Keep your dog away from the groomers during the first 48 hours of application so the product can work effectively. Spot-on treatments repel all life stages of fleas, including adult fleas, flea eggs, flea pupae, and larvae. They also banish other biting insects, including mosquitoes, gnats, flies, and more. If spot-on treatments are too abrasive to your dog's skin, there are a wide variety of flea and tick shampoos and dips made specifically with a variety of nurturing ingredients, including aloe, lanolin, and sunscreen.

The 48-hour rule also applies to dogs wearing flea and tick collars. Even though most collars are waterproof, they still need the two-day leeway to get proper flea and tick prevention underway.

Use Non-Stripping Shampoos

Once the two-day mark has come and gone, don't imprison your pup in the house. Most flea and tick products are waterproof, but "non-stripping" shampoos are best. These are formulated to not disrupt the medication that's working on your dog's skin, so your pet will continue to get protection against fleas and ticks.

Additional Tips

Monitor Your Pet's Weight: Ensure the flea product is suitable for your pet's weight.
Consult Your Vet: If the flea infestation persists, consult your vet to explore other treatment options.
Keep Up with Regular Treatments: Consistency is key in preventing new fleas from establishing in your pet's environment.
Flea's Life Cycle: Understanding the flea's life cycle is crucial. Flea preventatives work best when you consider the entire cycle, from flea eggs and larvae to adult fleas.
Certain Treatments: Some pets may respond better to certain treatments over others. If one flea treatment isn't working, consider trying a different product on the market.
Flea Treatment Working: It's important to monitor and ensure that the flea treatment is working effectively.
Topical Treatments: Ensure that topical flea treatments are applied correctly, especially around the shoulder blades where fleas tend to congregate.
Veterinary Medicine: Always consult with a veterinary medicine professional to get the best advice tailored to your pet's needs.
Prevent Fleas: Prevention is always better than cure, so keep using flea preventatives regularly.

Frequently Asked Questions

Why won't fleas go away after treatment?

There are several reasons why fleas may not disappear after treatment. If the infestation is very severe, it may take several treatments to get rid of all the fleas in your environment. The eggs and larvae that were present before treatment can be protected from the insecticide by the pupal case and continue to hatch. If you have a pet that is infested with fleas, but you treat him/her with medication, the medication will not kill off any of those eggs or larvae. The new flea population will come from other sources like wild animals or even other pets in your home.

Why is my dog still getting fleas after treatment?

There are a few reasons why your dog might be getting fleas after treatment. First, it could be that you are using the wrong treatment for your pet. Your veterinarian will be able to help you choose the right one for your pet's needs. Second, it could be that you have been treating your pet with medication for too long. The fleas may have built up a resistance to the medication, or they may have become resistant to the insecticides used in flea collars and other products designed to keep them away from your home. You should talk to your vet about switching medications or adding another treatment method to get rid of the fleas once and for all. Finally, it could also be that there is a flea infestation in your home or yard, and more than just one animal has been exposed. If this is the case, then it's best if both animals are treated at once so that they don't continue sharing their blood meals with each other while they're trying to heal from their own treatments!

Can I reapply flea treatment after 2 weeks?

You can reapply flea treatment after 2 weeks, but it’s not necessary. Fleas are a common problem for dogs and cats, and there are many treatments available to help you protect your pet from these pesky parasites. However, if you have applied a flea treatment in the past 2 weeks, there is no need to reapply it again. Fleas are typically killed by one application of a topical flea treatment that should last for 4-6 weeks or even longer, depending on the product used. Also, it is important to note that this will not be as effective as the first treatment. Fleas often lay eggs about two weeks after the initial treatment, which means that when you reapply flea treatment, you may only be killing a small percentage of the fleas that have already hatched. This means that it's best to treat your pet again before they start laying more eggs. Therefore, you don’t need to worry about reapplying your current treatment if your pet has been treated within the last two weeks.

How do you break the flea life cycle?

The flea life cycle consists of four stages: egg, larva, pupa, and adult. In order to break the cycle and get rid of fleas in your home, you must kill all four stages at once. The best way to do this is with a product that contains an insecticide that is effective against both adult fleas and their eggs. Some products are made to be used as a preventative measure. You're treating your pets' fur every 30 days or so in order to keep them from getting infested, while others are meant to kill adult fleas in one go. You'll also want to treat your yard and house for fleas. You can buy treatments that will kill adult fleas, eggs, larvae, and pupae at your local pet store or veterinarian's office. These treatments will also kill ticks in your yard so that you don't have to worry about them biting your pets when they're outside playing with their friends. If you have a pet who has been diagnosed with fleas by a veterinarian, you should talk with them about how best to treat your home and its inhabitants.

What kills fleas instantly?

One of the best ways to kill fleas instantly is by using a flea comb. A flea comb is a small metal comb with very fine teeth that can be used to remove the fleas from your pet's fur. The special design of the teeth allows them to penetrate into both the thick undercoat and the topcoat of your pet's fur to remove the fleas. Another effective product is a flea spray that comes in a canister. This canister contains a spray that you can use on your pet's coat, which will kill the fleas instantly upon contact with their bodies.
