Dr Mercola Healthy Pets Flea and Tick Defense For Pets 237ml

Mercola Healthy Pets Flea & Tick Defense Spray formula of natural oils from the Amazon rainforest is a safe and natural pest deterrent for your pet. It is not the individual elements that make Flea & Tick Defense so effective, it’s the expert blending and balancing of the Brazilian oils with the pure water that makes this product so effective.

Flea & Tick Defense Spray will provide good pest repellent protection; however, it will need to be reapplied every 2 to 3 days or as needed. It must also be reapplied if your pet gets wet. However, it is great choice for, say, a walk through the woods where there are a lot of pests, on a day walk, or a weekend camping trip.

Dr Mercola Healthy Pets Spot On Topical Herbal Repellent for Dogs & Puppies (3 applications)

A safe and effective herbal spot-on product using active herbal ingredients without the use of harsh chemicals. It is easy-to-apply and has a refreshing, pleasant minty smell. Each box contains 3 applications.

The many benefits of Spot On Topical Herbal Repellent include:

  • Repels fleas, ticks and mosquitoes
  • Each does lasts approximately one month, so there is no need to keep reapplying
  • It is easy to apply and has a fresh, minty smell
  • You don’t have to reapply after your pet swims or goes out in the rain
  • It also offers an option for sensitive dogs that don’t like to be sprayed with anything.

Directions For Use: To be used on Dogs & Puppies (4 months and older). Snap the cap off the tip of the Spot on Topical repellent applicator. Lift or spread the fur between your pet's shoulder blades until you can see their skin. Place the applicator tip directly on their skin and apply the recommended amount by gently squeezing the tube. Wash hands immediately with soap and warm water after applying.

How Fleas and Ticks Pick Your Pet

To understand how to best prevent these pests from attacking your dog or cat, we need to look at how they detect their victims. Fleas and ticks have several mechanisms they use to detect their hosts, and one of the most important ones by far is odour (olfaction). Fleas and ticks have olfactory receptor neurons narrowly tuned to specific odours they innately search for. Their simple olfactory systems consist of about 20 sensilla located on their first pair of legs. If this simple odour detection system senses something other than what it's been tuned for, the fleas and ticks will reject the host.

And this is how many of the flea and tick repellents on the market work today… they mask the specific odours on your pet that pests are searching for in the environment. If the formula is effective, fleas and ticks cannot smell, taste, or even identify the host they're seeking. So, they simply ignore your dog or cat. Though there are many “harsh chemical solutions,” Karen Becker has found some herbal repellents that work just as well, if not better.

Karen Becker’s Criteria For The Ultimate Pest Repellent

  • Has NO synthetic chemicals
  • Does not produce harmful effects when pets lick their skin 
  • Contains ingredients formulated by nature
  • Is available without a prescription and can be used daily
  • Has a pleasant odour but is designed to create an undesirable scent to pests
  • Needs to be fit for use on pet bedding and does not stain fur

For maximum protection Dr Mercola Flea products can be used by themselves or in combination with other Mercola Healthy Pets pest repellent products.

Ingredients include:

Lemongrass oil –not only does it help to repel fleas, ticks and mosquitoes it also promotes a shiny, healthy coat.

Cinnamon oil – a versatile essential oil which is an effective environmentally-friendly ingredient that helps deter mosquitoes, fleas, ticks, and other pests from attacking your dog or cat.

Sesame oil – a rich, almost odourless oil derived from tiny sesame seeds. When combined with other essential oils it helps protect against pests and promotes the health of your pet’s skin and coat.

Purified water –only the purest water is used to help blend and properly balance the unique formula of essential oils.

You need to be very careful when selecting a pest preventive for your pet. If too much of any one ingredient is not blended properly, your pet's skin could become irritated. The types of oils and correct percentages of oils blended together are not only important for assuring efficacy, but also safety - especially for cats.


Dr Mercola Healthy Pets Spot On Topical Herbal Repellent includes the following ingredients

Geraniol – The essential oil derived from geraniums (a flower), geraniol is an effective plant-based mosquito repellent. •

Wintergreen Oil – This oil is usually obtained by steam distillation of the leaves of the wintergreen plants, and is used for many things including to help relieve discomfort and pain, as well as to help repel insects.

Almond Oil – Used as a “carrier oil” that the essential oils are mixed with, almond oil is good for the skin and makes a great emollient. All these ingredients are healthy for your pet – as well as extremely effective repellents – so you can rest easy that your dog or cat will be protected.
