What to Consider When Choosing the Best Flea Spray

There are a variety of things to consider when choosing the best flea treatment. You should consider whether chemical, natural ingredients, or a combination of both suits your needs, the insect type you’re trying to eliminate, along with the different types of applications out there, how long they take to kick in, and how often you need to use them.

Chemical vs. Natural Ingredients 

Some people are nervous about the idea of using a chemical-based flea spray, especially on their pet. Fair enough, because certain chemicals (like imidacloprid, fipronil, permethrin, methoprene, and pyriproxyfen) have been known to cause serious health problems in animals. Even if you don’t have pets, people can be sensitive to chemicals, so it’s important to pay special attention to specific ingredients when shopping around.

The good news is there is another option; natural sprays. These are designed to kill and repel insects on contact. Natural sprays are intended to be used around the home on things like bedding, carpets, upholstery, and in the yard. Unfortunately, natural sprays aren’t always as effective in getting rid of fleas as their chemical counterparts can be.

Here’s a quick guide to common chemicals and natural oils that can help repel fleas:

  • Chemical flea sprays include the following:
    • Etofenprox: kills adult fleas
    • Nylar/pyriproxyfen: prevents flea eggs from hatching and young fleas from growing
    • Permethrin: treats many parasites, like fleas and lice
    • (S)-Methoprene: kills flea eggs and newly hatched fleas
  • Natural Oil flea sprays include:
    • Cedar oil: naturally repels fleas and ticks; safe for dogs and cats
    • Clove oil/eugenol: may kill fleas, but not all formulas are safe for cats

Insect Type 

Some flea spray products work against more than just fleas. You may need protection against a number of other pests, like ticks, flies, mosquitoes, and cockroaches, so know that there are all-in-one options on the market. Some flea sprays can be used directly on a pet as well as on surfaces around the home and in the yard.

Application

Consider the various types of flea treatments available and choose the right one for your needs:

  • Insecticide sprays with insect growth regulators (IGR) kill adult bugs on contact by preventing the eggs and larvae from developing into biting adults, eliminating the flea life stages at the beginning.
  • Diatomaceous earth, a natural, soft, white sedimentary rock powder, kills fleas, ticks, and pests on contact when the rock particles cause dehydration as they cut the exoskeleton.
  • Natural sprays kill insects on contact and repel others. Natural sprays can be used inside and outside your home in spots where fleas will likely be drawn to (such as carpets, upholstered furniture, bedding (including your pet’s), baseboards, and patio furniture/items).
  • Concentrated IGR prevents eggs and larvae from developing into biting adults.
  • Flea traps coerce pests over with lamplight, heat, and smell of the bait. Once there, the adhesive won’t allow them to move from the trap.
  • Flea foggers/bombs are not too effective because very little insecticide gets into cracks and hidden places.

Working Time

The amount of time flea sprays require to become effective is an important consideration in the spray you choose. To get the most time-efficient product, read the labels and specs of any spray you’re considering using and be sure to follow the directions carefully.

If the source of fleas is from your dog, removing them from your pet must be done along with all other areas of your home. Depending on the product used and level of infestation, it can take as little as 24 hours for the best flea sprays to work. But often, an entire infestation removal can take 3 to 4 months, as the fleas’ life stages may last this long. If all of the eggs and adult fleas are killed off together, you will successfully break the cycle.

Spraying Frequency

Flea home sprays come in bottles that range in size from 8 ounces to 1 gallon. The best option depends on the size of your home. Some manufacturers clearly label how much of the spray is needed to treat a particular area, so choose the appropriate amount.

Buying in bulk gives you the best value, but you don’t want to waste money on a formula you aren’t sure is effective. When trying a spray for the first time, it’s often best to start with a smaller bottle to make sure it works and that you’re satisfied with its results.

We researched the most sought-after flea sprays in their respective categories and discovered that the best options are determined by their type, compatible insect types, compatibility with multiple surfaces, and working time.

When searching for the best flea and tick home sprays on the market, the chemical sprays appeared to be the most popular for their immediate or quick effectiveness, their ability to kill ample types of insects, and, in some cases, an integrated insect growth regulator.

Tips for Using Flea Spray

There are many factors to consider when choosing the best flea spray, depending on your needs and those of your household members, including pets.

  • To eliminate fleas and other pests together, look for an all-in-one option.
  • If you have pets, get a treatment that can be used directly on your pet as well as on surfaces inside and outside your home.
  • Watch for chemical sensitivities—natural products are always an option.
  • Though buying in bulk gives you the best value, don’t invest in a large quantity of a new product until you know it will work—start with the smallest size to ensure you like the formula before buying more.
