Buyer’s Guide on Flea Killing Products

Lawn treatment against insects

Now that I have covered the top seven flea killers on the market, you know what to look for in such products. Still, there are some factors that you need to understand before making a purchase. Let’s take a look at the main features one needs to pay attention to while choosing a solution to terminate fleas in their yards.

Factors to Consider While Purchasing a Flea Killing Product

Purchasing a flea killer is not an easy task, but the information below will help you to make the best choice. The right treatment for your area depends on several factors, including the form of the product, the size of your yard, whether it’s safe for your pets, among others. Let’s take a look at them in detail.

Usage and Duration

Flea killing products come in several forms, such as granules, concentrates, sprays, etc. Some solutions only repel fleas or affect adult species, while others terminate insects in all life cycles, preventing them from developing and reproducing. The products that can help you to get rid of adult species together with their larvae are always pricier.

That’s why it is important to go through the label of the chosen option carefully to select the treatment that will provide the desired results.

Another factor to consider is the ease of use of the chosen product. Most such treatments come with spray applicator. Besides, you need to check how long the effect after the application lasts. The longer, the better. Most options continue to work for up to a month, and cheap ones can get washed out by the rain.

What’s more, it is vital to consider where the selected treatment can be applied. Make sure that you can use it on as many surfaces as possible. The allowed areas should include shrubs, flowers, gardens, vegetation, lawns, etc. This way, after the application, you will ensure that the biggest part outside your home is treated. Moreover, some products can be applied even indoors, so take it into account.


Can a spray work for large yards or only small ones? For a small area, I recommend you to get a spray with a lower capacity. However, for bigger territories, you will have to either purchase a concentrate product or apply the solution several times to achieve the desired results. Besides, some products have the approximate coverage specified on their labels.

Flea killing remedies


It is essential to check whether the product is made of chemical or natural components. Solutions with natural ingredients are usually non-toxic to kids, pets, as well as the environment. However, they are not as effective as chemical pesticides.

Flea sprays that contain chemical components tend to be more powerful. While not all such products are non-toxic for pets, especially cats, there are a few safe ones, too. However, you need to check the instructions carefully when opting for a chemical solution. It is not only for safety factors but also to ensure that you apply the product correctly.


It is vital to consider whether or not the particular solution is safe for usage around your pets. Carefully read through the components, as well as warning labels. While some sprays are made of natural ingredients, others contain harmful chemicals.

So, some solutions are safe to spray with pets around, while with others, you will have to apply the treatment and let it dry before letting your pets play outside. So, make sure to consider all of these factors before purchasing any product to terminate fleas in your yard.


Below are my answers to the most common questions on flea killing solutions. I hope that this information will help you to sum up all the knowledge gained on this matter.

What Can I Use to Kill Fleas in My Yard?

There are several ways to terminate fleas around your house. The two main methods include chemical flea killers, such as using sprays, as discussed in this review. I find it the most working way to eliminate these species around your property.

Alternatively, you can opt for some natural homemade remedies to apply around your home. However, be ready that they won’t be as effective as special flea control products. Here are some natural options you can try to get rid of this species around your house.

Diatomaceous Earth (DE)

It contains silica shards used to slice through the waxy exoskeleton of the flea, leading to the dehydration of their bodies and the eventual death of all the adult pests and their larvae. While handling this product, make sure to put on gloves to prevent your hands from drying.

Sprinkle food-grade DE on your pets’ beds, as well as furniture. Let the product settle and leave it for seventy-two hours. Finally, thoroughly vacuum all your surfaces to eliminate pests and remains of diatomaceous earth.

Dawn Dish Soap

This non-chemical solution can also be used to eliminate fleas. It destroys their exoskeletons, therefore, killing them. Soap works by breaking the waxy part inside the breathing system of an insect, letting moisture enter, leading to asphyxiation. Besides, this product lowers the surface tension of water. Thus, it causes fleas to be immersed in water after they sink, working as a surfactant.

Fine Salt

Fine salt will terminate fleas since it is well-grounded. Spread the salt on the intended places, as well as other contaminated areas, including your carpets and furniture. Spray it with water and let it sit for a maximum of two days, and fine salt should terminate fleas. As the saltwater keeps drying, it absorbs the moisture from the surroundings, thus, terminating insects by desiccating them upon contact.


These tiny, wormlike insects live in the soil, being a safe, natural way of terminating fleas in contaminated areas. Nematodes can help you to get rid even of flea larvae, and they are particularly sold for eliminating pests in yards. Simply mix these creatures with water and sprinkle the solution over your lawn.

How Long Does It Take Flea Yard Spray to Work?

After you apply a high-quality flea killer, most adult fleas will be dead within one to three days. However, the products that contain all-natural ingredients may take up to seven days and several applications to work out.
Always check the labels of the selected treatments to choose the right option for your needs. Also, such products differ in the longevity of their effects, so keep it in mind, too.

What Do I Do If I Put Flea and Tick Spray on My Yard and It Rains?

Usually, light rain will barely have an effect on the efficiency of flea killing products. However, in case there is a heavy downpour, there is a very high likelihood that the contents will be washed out, reducing the effectiveness of the treatment. Thus, you will have to apply the solution again.

It also depends on how long after the treatment the rain pours. If the product has already settled in the soil for a day, and it rains heavily, it will probably still be effective.

Besides, there are weather-proof solutions available on the market. It means that they can’t be washed out by rain or affected by directed sunlight, so you won’t have to worry about the weather at all.

Final Thoughts

In this article, I have discussed the best flea killers for yards on the market. Now, it should be much easier for you to choose the product to eliminate pests in your area. Besides, here, you could find answers to some of the commonly asked questions on flea control products, as well as factors to note when selecting such treatments.
