 Wondercide - Flea, Tick & Mosquito Spray for Dogs

View on Amazon

The Wondercide FTPH004L Flea Treatment is a natural and effective method for controlling fleas, ticks, and mosquitoes on your furry companions.

By using natural essential oils, this spray is proven to kill pests on contact, repel them, and break their life cycle by eliminating eggs, larvae, and adults. When used as directed, it is harmless for use on canines, cats, and even puppies and kittens.

This 3-in-1 plant-based treatment is effective not only on canines, but also on surfaces and furniture to eliminate fleas and ticks lurking in your home. It has a revitalizing lemongrass scent that will freshen up your household.

The spray contains sodium laureth sulfate (SLS), which may irritate the skin of canines with sensitive skin, despite the fact that it is less expensive than typical tablets and spot treatments.

Therefore, it is recommended to test a small area on the back of your pet’s neck one hour prior to full body application.

The Wondercide FTPH004L Flea Treatment is an alternative to collars, pills, chewables, and drops that utilizes the power of nature to protect your pets and home from pests.

This application eliminates ticks, fleas, and mosquitoes, along with flea eggs and larvae, to stop an infestation immediately.

This spray is not only an effective natural alternative to chemical treatments, but it is also an excellent value. It can be used on surfaces that have been spot-tested as long as the space is well-ventilated and promptly aerated after application.

It is essential to note, however, that this aerosol contains peppermint oil, which is toxic to cats. Additionally, it may leave a faint oily coating on your dog’s fur, particularly if they have thick fur.

Despite these potential drawbacks, the Natural Care 40112-4P Flea Spray Solution is an excellent option for households without cats seeking a natural flea and tick treatment for dogs.

The formula utilizes the natural effectiveness of plant extracts, such as peppermint oil and clove extract, to eliminate pests on contact. It can also be used without leaving residues on pet bedding, pillows, blankets, carpets, rugs, draperies, upholstery, and countertops.

By providing chewable protection against fleas and ticks, these tablets help prevent flea infestations, which is particularly significant in regions with a high flea population.

In addition, they are much easier to administer than topical remedies, which can leave your dog’s fur oily and may even cause an allergic reaction.

It is important to note, however, that these tablets can be quite expensive, especially for dogs weighing 30 to 40 pounds or more.

To avoid potential digestive issues, we highly recommend consulting with your veterinarian before giving these pills to your dog, especially if they have a sensitive stomach.

Despite these possible drawbacks, the ColoradoDog EcoFlea Flea Treatment for Dogs is a superior natural alternative for flea and parasite prevention.

It is important to note that Arava Natural Flea Treatment may not be as potent as traditional topical treatments, and your dog may still have ticks and fleas after use. Multiple areas need to be treated, and the product’s strong odor can be overpowering, making application difficult.

How to Select the Best Natural Flea Treatments for Dogs

1. What Components Do Natural Flea Treatments Contain?

Most popular and commonly used dog flea remedies on the market include synthetic active ingredients.

The Environmental Protection Agency (EPA) and the Food and Drug Administration of the United States oversee all flea treatments (if the product is oral).

Non-profit watchdogs have recently criticized the EPA for “ineffective safety standards” around several authorized substances.

Flea treatments have been reported to be poisonous to dogs, despite the fact that many dogs tolerate them well. Mild cutaneous or gastrointestinal irritation to severe poisoning are all possible reactions.

Dogs with impaired immune systems, such as aging, developing, or sensitive dogs, are more prone to have these unpleasant reactions. As a dog owner, you should prioritize researching flea treatment ingredients.

While synthetic flea treatments may be effective and pose no health risks for your dog, natural options may be preferable for the health of some dogs.

Given the stakes, finding an appropriate remedy might be daunting; thus, continue reading to discover some key points to consider when choosing a natural flea treatment and repellent for your dog.

2. Ingredients that naturally combat fleas

  • Cinnamon is a potent natural insecticide against a broad variety of insects, including fleas. Cinnamaldehyde, the main component of cinnamon, has been experimentally proven to be harmful to insects but not to mammals. Moreover, cinnamyl acetate, the component responsible for cinnamon’s distinctive aroma, is a potent insecticide and repellent.
  • Clove is a well-known insecticide regularly used by gardeners to protect crops from pests. This ingredient may be effective in dog flea treatments, but it should be used with caution because it is toxic in large quantities. If used with a shampoo, make sure they are well-rinsed. If used as a topical therapy, it should only be applied to areas that your dog cannot reach to groom.
  • Cedar oil is actively regulated by the EPA as a pesticide and flea treatment. It has been demonstrated to be both effective and safe. The cedrol present in cedar oil repels insects.
  • Cottonseed has been used as a natural insect repellent for millennia. In contrast to many other natural compounds, cottonseed is not toxic to insects. It instead suffocates little insects and their eggs, making it a perfect supplement to flea treatments for dogs.
  • Diatomaceous Earth: Diatomaceous earth is another organic pesticide that is non-toxic. Diatomaceous earth encases little insects and dries them out by removing their natural oils, as opposed to killing them through toxicity.
  • Neem: Although neem oil is not a crucial active ingredient in flea management, it can be useful for repelling fleas. Incorporating neem oil into natural flea cures for dogs hydrates the skin and acts as an antibacterial and antifungal for skin irritations or infections.
  • Although yarrow does not kill fleas directly, it can be an effective supplement to natural flea treatments for dogs. The anti-inflammatory properties of yarrow oil and powder may aid in the treatment of any ailments or discomfort caused by flea bites on your dog.
  • Boric acid is a moderately dangerous insecticide, so veterinarians recommend using it as part of an EPA-approved product rather than as a home remedy. Thus, you can be assured that the boric acid levels in your house are safe. Boric acid is toxic to insects, but because fleas rely exclusively on your pets’ blood, it has no impact on them. Instead, boric acid dehydrates the exoskeletons of invertebrates, resulting in their death.
  • Spinosad: When this chemical is listed on the back of cat flea treatments, people often mistake it for a synthetic substance. Despite its unnatural-sounding name, it is a natural substance. Spinosad is produced by naturally occurring soil microorganisms. It is a potent insecticide used to kill and repel a wide variety of insects, including fleas. Spinosad is most effective when swallowed by fleas; hence, it is most commonly encountered in oral preparations.
  • Peppermint: Since the strong scent of peppermint components is excellent at repelling insects, this element can be a valuable addition to many flea treatments for dogs. Due to its anti-bacterial, anti-fungal, and antiviral properties, peppermint can help reduce secondary infections caused by flea bites and skin irritation.

3. How to Eliminate Fleas from Your Home

Because synthetic materials are very effective, they are widespread and popular.

Despite the fact that natural goods can likely provide equivalent outcomes, certain items may be ineffective if extra home actions are not also performed.

Sadly, eliminating fleas from your dog is only half the battle. Fleas require the blood of your pet to survive, yet they may live in your house for two to fourteen days.

In addition, the flea egg incubation time might extend up to 14 days. Considering these conditions, your dog is likely to acquire more fleas weeks after a successful treatment.

In addition to treating your dog for fleas, you should set a flea mat in your house. Here are our best recommendations:

  • Following a flea treatment, frequent cleaning of floors and furniture will capture any stray fleas, flea larvae, and flea eggs.
  • High heat will kill fleas at any stage of growth, so incorporating steam into your cleaning regimen might be advantageous!
  • Fleas should be eliminated from all household bedding (both human and feline) at least once a week. After cleaning, tumble drying might be advantageous since the heat will destroy any remaining insects.
  • Utilize repellents – Using repellents throughout the house will discourage fleas from inhabiting your home. Existing fleas will be expelled, and new fleas will be prevented from entering.


1. What instantly eliminates fleas on dogs?

A fast-acting oral tablet containing Nitenpyram is the safest and most effective way to instantly eliminate fleas on dogs. Another option is to bathe your dog in hot, soapy water containing Dawn, but this is not a long-term solution.

2. What naturally eliminates fleas?

Both white vinegar and apple cider vinegar are effective natural flea treatments, and can be used interchangeably. Combining essential oils such as cedar or lavender can enhance the potency of a solution.

To ensure that all fleas are eradicated permanently, you can apply a vinegar-soaked cloth to affected areas and your pets.

3. Can dogs use essential oils as a natural parasite treatment?

Yes, lavender, peppermint, and eucalyptus essential oils can be used as a natural flea treatment for dogs. However, it is important to use them in the proper dilution and under the guidance of a veterinarian.

4. Are natural flea treatments safer than synthetic ones?

Natural flea remedies may be safer than chemical treatments because they are less likely to contain hazardous chemicals. However, it is essential to choose a safe and effective product for your dog, whether it is natural or synthetic.

5. Can food-grade diatomaceous earth be harmful to dogs?

Yes, inhaling food-grade diatomaceous earth can be toxic to dogs. It is important to apply it carefully and avoid using it near your dog’s skin.

6. Are natural flea treatments safe for pregnant or nursing dogs?

Some natural flea treatments may be safe for pregnant or nursing dogs, while others may not be. Always consult your veterinarian before applying any flea treatment to a pregnant or lactating dog.
