Factors to Consider When Choosing a Flea Treatment

Purchasing a flea treatment is no walk in the park. The choice will depend on a couple of factors, including the form it is in, the usage, the dog’s covering, the safety of use on pet and your pet’s size, as well as other factors. Let’s talk about these aspects in detail.


There are so many flea killing products that come in different forms, such as granules, concentrates, sprays, tablets, drops, etc. Some products repel parasites, others exterminate them during the entire life cycle, preventing them from developing and re-infesting, while others will only kill adult fleas. Some products can handle all these problems, and they are pricier. It is important to go through the label properly to determine the product that will meet your expectations.

Another aspect to consider is the ease of using these flea treatments. However, a lot of them come with an applicator. Besides, how long does the product last? The longer it does, the less frequently you will need to use on animals. Most products will last a month, with very few offering up to 8 months of protection.

Level of Infestation

How extensive is the flea infestation? The severity of the infestation will determine the strength of the product that you get. It is better to get a chemical pesticide rather than an organic one for a severe infestation, as it will effectively kill the pests. However, a treatment made of natural components would be ideal for light to medium infestation.

The Ingredients

It is crucial to find out whether the treatment consists of chemical or natural components. Products that include natural components tend to be non-toxic for kids, pets, as well as the environment. Still, they are not as effective.

Those that consist of chemical ingredients, on the contrary, tend to be highly effective. While not all of them are safe for pets, there are several non-toxic ones as well. Still, you should always follow the manufacturer’s instruction carefully. You should do it not only for safety precautions but also to make sure that you get the desired results.


There are several things to consider here. First, it is vital to check whether or not the treatment is safe for your pets. Carefully go through the ingredients, instructions, and warning labels. While some treatments are made from natural ingredients, others use chemicals. Some of them are safe for use on pets, while others are not.

Another factor to consider is the size of the pet. The size and weight of the dog matter a lot. They will determine the type of treatment that you will use on your canine. While some products are ideal for pups weighing below 20 pounds, other products will work well on larger dogs. Make sure to read the instructions to determine which product works, depending on the size of your pet. Besides, you should also take into account that most of these products are not safe for use on pups.

Another concern is skin type. What is your pet’s coat type? A topical treatment will work well for a thin coat, while a collar will be effective for a thick coat. Make sure to research and consult your vet before settling on any product type.

Various Types of Flea Treatments

Products work differently to achieve the same goal that is dealing with pest infestations. Besides, we all have different preferences for our pets. That’s why there are several flea treatments on the market to choose from, including collars, pills, drops, sprays, etc.


Drops commonly come in topical solutions and are ideal for terminating already existing parasite infestations, while preventing outbreaks that could occur in the future. Such products are applied directly onto the skin, in between shoulder blades. Most of them are resistant to water.

Oral Pills

Oral treatments for pests are fast-acting and effective. The medicine will move through the canine’s bloodstream, as well as the surface of the skin, aiding in exterminating biting parasites. Besides, when combined with other treatments, they will help get rid of intestinal parasites as well.


These treatments are thin, convenient, and easy-to-adjust. The synthetic band is covered with a chemical that is intended to repel pests. Most of them will last a couple of months and are an economical option.

They work well in between baths since they will wash off once your pet becomes wet. Still, most of them are budget-friendly and are somewhat effective.

Natural Remedies to Get Rid of Pests

There are several ways to exterminate fleas on your pets. The two main techniques include chemical solutions such as using sprays, pills, drops that I discussed in the review. They are the most effective ways of eliminating fleas on your pets. However, there are a couple of natural home remedies. It is important to note that they aren’t as effective as the chemical flea control methods. Still, you can try out some of the following natural remedies.

Diatomaceous Earth (DE)

It has silica shards that work by slicing through the waxy exoskeleton of the parasites, leading to a lack of moisture, and eventually killing the larvae and pests. Make sure to wear gloves while using it to prevent your hands from drying. You should also sprinkle it on your pet beds, let it settle, and leave it for 72 hours. Once done, you should thoroughly vacuum all the surfaces to eliminate these parasites and their whole life cycle.

Lemon Water

Probably it’s not what you expected on the list? Well, lemon water is effective in getting rid of pests. Cut a lemon and soak it overnight in water. Pour the water to a spray bottle and use this solution on your pup as well as in the places that he frequents.

Dawn Dish Soap

This non-chemical insecticide is used to get rid of pets. It destroys their exoskeletons, thus, killing them. It works by breaking the waxy component within the breathing system of a bug, letting moisture enter, resulting in asphyxiation.

The soap lowers the surface tension in water. So, it makes the pests be immersed in water after they sink, working as a surfactant.

Essential Oils

Get essential oils, including lemongrass, rosemary, lavender, etc. to deal with a flea infestation. Besides, they will leave your space smelling great. However, you should consult your vet first to ensure that the scent is safe for your pup.

Fine Salt

Household or sea salt will get rid of fleas since it is well-grounded. Simply splash the salt on the contaminated places. Let it sit for a maximum of 48 hours. Once you’ve sprinkled the fine salt and sprayed water all over it, it should eliminate the fleas around your house. Besides, as the saltwater keeps drying, it will ingest the moisture as well as water from the surroundings, thus, terminating the bugs by desiccating.

What Are Main Ingredients in Dog Flea Products?

There are so many products to get rid of parasites on pets. However, most of them are made from the same active components for repelling and terminating pests. The four key components used in these treatments include permethrin, fipronil, imidacloprid, and s-methoprene.

Frequently Asked Questions on Pest Infestations

I have explained the main aspects to consider when choosing a flea treatment as well as the different treatments for parasites, including natural methods. Of course, there are commonly asked questions regarding these products. So, this section addresses the frequently asked questions on the best and safest flea treatment for dogs.

How Long After Flea Treatment Can I Bathe My Dog?

Wait at least 2 days. It’s a common rule to wait approximately 48 hours after an application or even after taking oral pills. In this way, you will achieve maximum effectiveness.

How Often Can I Bathe My Dog with Flea Shampoo?

Do it as rarely as possible. There is no need to shampoo your dog regularly unless he is actively infested. If he is, then doing it once or twice a week should be okay. Once you get rid of the pests, take a washing break.

How Long After Flea Treatment Will My Dog Stop Scratching?

Most pests will die within 1 to 3 days. So, your pet should stop itching within 24-72 hours. However, avoid washing, sweeping, or vacuuming your floor for at least 14 days after treating, since there is a high chance that there are still eggs continuing to hatch.

How Often Can You Put Flea Medicine on A Dog?

It depends on a couple of factors. They include how often your pet gets infested and the product instructions for their usage. However, it’s better to use flea medicine every 2 or 3 months to keep your pet in tiptop condition while exploring the outdoors.

What Happens If You Put Cat Flea Medicine on A Dog and Vice Versa?

You should always carefully read the instruction to learn whether the product is safe for usage on both pets. While some products are safe on both dogs and cats, others are not. So, most companies have created different treatments for each of these pets because dog products can be especially toxic to cats. However, cat treatments are rarely toxic to dogs.
