Fleas are small in size yet the most dangerous insect that sucks your blood. Fleas can be harmful to both your pet and your children. You can find fleas in your home, in your pet’s fur, or maybe in your car.

If you see any fleas around your home or anywhere else, you must require the best flea insecticide that will help you to get rid of them completely.

But seeing too many options in the market for flea insecticide spray or medicine will make you confused. But you have to comprehend some common factors before buying flea insecticide for your home.

And if you can recognize these major factors before getting flea insecticide, it will be easier for you to choose which flea insecticide you’ll need.

Chemical or natural ingredient

It is crucial to know what is inside the flea insecticide. Some people do not feel safe spraying flea insecticide that has chemical ingredients, especially on their pets.

Because certain chemicals such as imidacloprid, fipronil, permethrin, methoprene, and pyriproxyfen can cause health problems in some dogs and pets.

For that reason,

People are nervous about whether to get chemical flea spray or natural flea spray, especially for pets.

If you don’t have pets, you still want to know the ingredients of the flea insecticide because some people are allergic to some kinds of chemicals.

Knowing the ingredients whether it’s for you or your pets while getting flea insecticide is a vital point.

Thankfully if you’re allergic to some type of chemicals or nervous to use chemical spray for fleas then here is an option of getting natural flea insecticide.

Natural flea insecticides can kill insects and other types of fleas but it’s not effective every time. Natural flea insecticides may kill some of the fleas but it is not guaranteed to kill them effectively.

Types of insects

If you live in an area where insects are constantly getting inside your home then spraying for only fleas won’t help. Because you can not buy an individual spray for every insect.

For that reason, you can choose a flea insecticide that can kill other types of insects as well. Such as mosquitoes, flies, cockroaches, etc are some insects that should be also killed by flea insecticide spray. Now you can get the all-in-one option in your flea insecticide spray so that it can kill every insect at your home.

Even you can directly spray the flea insecticide on your pet’s body without any problems. So if you want a flea insecticide then make sure the insecticide is versatile for every insect.

Application method

Not only flea spray but also various flea insecticides are available to get rid of fleas from your home or somewhere else. So make sure to know all the application methods of flea insecticide before buying them.

Insect growth regulators insecticide spray: this flea insecticide has insect growth regulators that kill adult bugs and fleas and prevent larvae from growing.

Concentrated IGR: concentrated IGR prevents larvae from getting spread and butting adults.

Flea traps: flea traps help to coerce pests over with lamplight, smell, and heat of the bait.

Flea bombs: flea bombs help to get rid of fleas from every corner of your house. But they are not too effective to get rid of the fleas properly.

These are some effective application methods for fleas and make sure you’re choosing the right method for flea insecticide.

Flea Control

Working time

Effective working time should be in consideration if you are choosing a flea insecticide spray for you or your pets. Sometimes you want to get rid of the fleas in a day, then you should get a spray that can kill the insects in 24 hours.

Make sure to check the labels on the spray bottle of flea insecticide and check if it can kill the insects in 24 – 26 hours. Some flea insecticides are unable to kill the insects in a day and they usually take 3 to 4 days to kill the insects effectively.

If you want less time-consuming flea insecticide spray then it may contain some chemicals that result in killing the insects in 24 hours. So people who want effective working time for flea insecticide should choose chemical spray for them.

The natural flea insecticide spray won’t kill the insects in one day because it contains natural ingredients that are not strong enough. But natural ingredients won’t give you any allergic reactions and other problems you may face with chemical flea insecticide sprays.

Size of the flea insecticide

If you have too many insects in your home or car then make sure to check the size of the flea insecticide spray bottle. Because you may have to spray the flea insecticide frequently to get rid of fleas completely.

Often spraying one time doesn’t give you an effective result to get rid of the fleas. So make sure to spray the flea insecticide frequently on the areas where fleas are living.

You have to spray other areas where fleas are not living to prevent the larvae from growing.

Flea home spray’s bottle size ranges from 8oz to one gallon so that you can choose what bottle size is suitable for you. If you don’t have too many insects then we recommend you get small bottles of spray.


Do dryer sheets repel the fleas?

The dryer is the best weapon against fleas and it kills fleas instantly. The high temperature inside the dryer is enough to kill all the fleas from your bed sheets, clothes, curtains, etc. So if you witness any fleas then put the clothes in the dryer.

How do I treat my pillow for fleas?

If you see any fleas on your pillow then put the pillow in the hot water and wash it. Or you can spray flea insecticide to get rid of fleas then wash the pillow with hot water and put that in the dryer. The high temperature along with flea insecticide will get rid of fleas completely.


Getting rid of the fleas seems easy but it is tough work to do. Even if one flea gets away from the Insecticide then it will reproduce again. So getting the best flea insecticide for fleas is crucial for your home and your pets.
