Most professionals know how to make the best pick, but ordinary consumers need a little bit of guidance for them to choose the right bombs to kill fleas once and for all. Therefore, you should consider the following aspects when making your purchase.

Most people think that all foggers available on the market have the same components to kill the fleas.

Moreover, some pests may be resistant to particular pesticides, and thus, it is best to purchase flea foggers that work on various types of pests.

Re-Infestation Prevention

I strongly advise that you should buy a fogger that can prevent future infestation of fleas. Most foggers that have been reviewed above prevent re-infestation due to their long residual effect. That means they can still kill pests long after you have done the spraying.

Aside from checking whether the foggers have a residual effect, you should also find out whether they can regulate growth or kill the eggs. Since flea eggs can last for a long period before hatching, you need to kill them to avoid any infestations in the future.

Safety Levels of the Pesticides

Keep in mind that you will be using these chemicals in your home around your children and pets. That’s why you should make sure that pesticides have very minimal health effects because it’s impossible to find one with no negative effects. Try to look for an insecticide that is not poisonous or one that has no lingering smell because inhalation of these pesticides can also be dangerous. Make sure to follow safety precautions.

Size of the Area You Intend to Use It In

Foggers are available in packages that differ in the amount of the product. As such, you need to get more foggers if you have a big house or the infested area is large. Additionally, flea infestation happens rapidly. That’s why you should purchase extra foggers so that you can spray your home frequently to prevent infestation.

The Vacating Time for the Different Foggers

Most flea bombs can be toxic to people, so you will need to leave your house after spraying them. The majority of them require you to stay away from the sprayed area for about 2-4 hours. Inhalation of these pesticides may cause health problems to your family and your pets and, therefore, it is a very important factor to consider.

Frequently Asked Questions

Most people who have never used flea bombs before may have various questions. This section will help you get the answers to common questions asked by consumers when they are planning to make a purchase.

How to use a flea bomb?

Setting up a flea bomb may take time and a little more input to achieve better results. If you don’t know how to use a flea bomb, then you can seek professional guidance. Flea bombs mainly work best in areas without obstruction, and, therefore, you may need to take some household materials outside. It’s better to take out kitchen appliances if possible so that you can spray the cabinets and other areas where fleas hide.

You should be very careful when using a flea bomb and follow the instructions to avoid health complications. After spraying the area, you should clean all garments and beddings properly. However, you should avoid washing the carpet to ensure the pesticide works on the pests for a few more days.

How do flea bombs work?

A big concern of many pet owners is “how do flea bombs work?” To use these foggers, you need to first put it in a can that has high pressure and activate it. Once activated, the aerosol will start releasing the pesticide. Leave the house immediately after activation for the time recommended by the manufacturer. When the mist settles down, it has a toxic effect on the pests it comes into contact with.

The mists can penetrate the small holes and cracks to the hidden fleas. One flea bomb may not be enough to achieve complete eradication, so you will need to do this frequently. So, if you have been asking “Do flea foggers work?”, the answer is yes, but only if you follow the manufacturer’s instructions.

How long does it take to flea bomb a house?

After setting up and activating the fogger, you should step out and wait for the mist to settle. It may take up to 8 hours, depending on the pesticides. So, how long does it take to flea bomb a house?” Most pesticides may take 2-4 hours. It’s approximate time when flea bombing takes place.

How long to stay out of house after bug bombing?

Most manufacturers indicate the vacating period on packages to inform consumers of how long to stay out of house after bug bombing. Most of them require you to stay out for around 2-4 hours. This time is enough for the fog to settle down, and for most pesticides, the air will be clear of the smell in case it is not odorless.

If you are planning to go for a vacation, then it’s the best time to set the flea bombs since you should always ensure your family is safe and that they can be out of the house during the stipulated time.

Are flea bombs/foggers safe for pets?

These pesticide sprays are made of aerosols, which may be harmful to both humans and pets. Mostly, these bug killers become dangerous if instructions are not followed. Besides, pesticides contain toxic components, and if not used properly, they can cause health problems.

There are cleaning shampoos for pets, for example, dogs or cats, and they can be used to get rid of the fleas from them. The shampoos are friendly to pets. But after cleaning the animal, you should also clean the pet’s sleeping place to avoid the pests jumping on your pet again.

Where to buy flea bombs?

If you have decided to purchase these bug killers, it’s important to find a store that offers high-quality products from reputable brands. Many online stores offer flea bombs, but it’s better to make your purchase at a well-known place to avoid buying counterfeit products. I can recommend Amazon.

Can fleas cause diseases?

Yes, they do, although these diseases are rarely transmitted to humans. For example, cat fleas can transmit tapeworms. Flea borne typhus is also a disease transmitted to pets by fleas. They get this disease from biting infected rodents, and when the same flea bites your pet, it passes the disease to the animal.

Can flea bombing get rid of bed bugs?

It is rare to find foggers that can kill bed bugs because bed bugs are mostly resistant to these insecticides and may require stronger chemicals. The best insecticides for bed bugs contain pyrethrin and other botanical chemicals. However, some manufacturers are trying to combine these chemicals in flea foggers. So it is vital to learn about the components of the product to determine if it is capable of killing bed bugs.

Can flea foggers cause damage to electronics?

Most people think so, but it is not true. Your electronics will not be damaged by these insecticides, although you should remove them if they obstruct the penetration of the pesticide to the infested areas.

Can flea bombing kill plants?

If you have a flower or other plant in your house, you might be wondering whether your plant will be safe during flea bombing. There is no need to worry. Your plants will be safe, especially if you follow the manufacturer’s instructions. Most pesticides on the market are not harmful to plants.

The Bottom Line

Using flea bombs to kill pests is considered as one of the best methods to control flea infestation. While most of the foggers deal with the flea adults, they differ in their strengths to kill larvae and flea eggs that have not been hatched. That’s why the most effective flea bombs are the ones with the insect growth regulation molecules and those that kill eggs before they hatch.

The effectiveness of foggers is also determined by the long residual effect of the pesticides because it ensures perfect control of the future infestation. Also, you should purchase a pesticide that can handle a variety of pests. Eradicating fleas should not be much of hassle, especially if you get the right bug killer.

There is a variety of pesticides available on the market, so when making a choice, you should take into account such aspects as high quality, affordability, versatility, and safety. Make sure that the products are suitable for your home, taking into account the size of the area you want to use them on. Finally, if you feel like you cannot handle the problem alone, you can seek professional advice on how to get rid of the fleas.
