Fleas are tiny creatures that might seem insignificant at first, or like something that will only trouble your pets, but they are a huge problem despite their small stature. If you don’t take care of the problem in time, you could have a full-blown infestation on your hands. Things like mosquitoes are nothing compared to a horde of these pests running around your house biting everything in sight at all times.

In such cases, you might want to resort to calling an exterminator, but the best way to get rid of the fleas is just buying and using a fogger. Also called “flea bombs,” these insecticides are easy to use and will usually get rid of not just fleas but also other insects that you might have trouble with.

Here’s how useful the best flea foggers can be and why you should get them even if you only have a minor flea problem.

Why Buying a Flea Fogger?

Flea foggers are one of the finest ways out there to get rid of flea infestations quickly and efficiently. They are insecticides that use a few different targeted chemicals for killing fleas. Pyrethrin and pyrethroid are the most common ones, though there are products that use others, like nylar, tetramethrin and so on. Some contain only one of these chemicals, but the better brands usually contain two, three or more of them to make sure the fleas are dead.

Get rid of bloodsucking pests with the best flea fogger

Using flea foggers is mostly simple. You just place them in a room and let them fill it with the gas. Of course, you should make sure that everyone is out of the room beforehand since these chemicals can be dangerous to inhale. You also need to make sure the windows are closed, and all the drawers and similar places where the fleas could hide are open, and the gas can get into them.

Turn off any electrical appliances beforehand, just in case, as the gas can be flammable. Cover or put away any food, so it doesn’t get contaminated. After around two or four hours it will all be done, and you can come back in and air out the place. The fleas should be dead in a matter of days if not hours.

Of course, they usually leave eggs, which the flea fogger won’t kill, so you might have to repeat the process once or twice after a few weeks, but that will get rid of them completely. Make sure to vacuum before and after the process as well.

But what if you have no flea problems? Well, despite the name, flea foggers are usually good at killing more than flees and can work on other insects or arachnids you might have in your home. They can work on mosquitoes, centipedes, spiders, scorpions, cockroaches and more. Be sure to check the label to see what the product works on.

Of course, flea foggers are not an entirely surefire solution, and you also have to treat your pets for fleas to make sure they don’t bring them back in. Still, they will get rid of almost all the fleas in a few treatments and are one of the best and cheapest ways to deal with flea infestations.

Not all foggers are equally good, however, and some will do little more than stink up your place, leaving the bugs alive and well. Unfortunately, it is difficult to tell if this is the case before you buy and use the product, so you might end up with a dud without knowing it if you’re not careful.

Not a lot of people have the knowledge necessary to spot a good fogger at first glance, but we have decided to impart that knowledge upon you. Here we will discuss the best products we found during our testing process, review them, add in some opinions from genuine users and discuss the most important aspects of foggers.

Meet the Best Flea Foggers

Hot Shot 100047495 HG-20177 No Mess Fogger, Aerosol, 3/1.2-Ounce, Model:100047, Pack of 1

The Good: Effective immediately, non-flammable and doesn’t leave any nasty smells around

The Bad: Not effective in the long run and doesn’t offer a lot of cans for the price.

The Bottom Line: Overall, this is quite an effective product in the short term, more than any other out there. Even though it lacks longevity, we still believe it is more than worth its high price due to how well it works.

Black Flag 11079 HG-11079 6 Count Indoor Fogger, Clear

The Good: You get a lot of it for the price, and it can last for quite a while.

The Bad: Leaves a smell, is quite flammable and doesn’t kill a lot of insects.

The Bottom Line: Despite some upsides this product has, the main issue with it can’t be overlooked – it doesn’t work well and isn’t effective at killing most insects. Because of that, it is a difficult sell even at this price point.

Precor Plus IGR Fogger Flea Control 6(3 oz.) cans

The Good: It’s long-lasting and effective while being able to cover a huge area.

The Bad: The can is poor at dispersing the chemicals, and it costs much more than other products.

The Bottom Line: There’s no doubt that this is an effective and long-lasting flea fogger. However, it’s hampered by how poor the can it comes in is, and it costs far too much for us to be able to recommend it.

This is what we think about the foggers in general. Scroll down below to see why.

All of the Factors Considered

Foggers are quite different from normal bug spray even though they might seem alike at first glance. Applying the same strategy to buying them as you do for bug strays is a mistake a lot of people make, and they end up with a bad product because of it. Because of that, we decided to write up a list of the most important things you should consider when buying a fogger, based on our extensive testing.


What matters most about a flea fogger is how effective it is. There’s no point to it if it doesn’t kill fleas, after all.

There are a few ways you can gauge the effectiveness of a given product before you even use it. The first one is by looking at which chemicals are used. The more different flea-killing chemicals there are in a product, the more certain it is that it will kill most of the fleas in your house.

Another thing you should check it is the length of its effectiveness. Some products may stay effective weeks or months after use, and that can prevent any resurgence, which makes them more effective.

If you’re looking to kill more than fleas you should see what bugs the fogger can affect. Some foggers can kill a huge range of common pests, and that can be a large bonus, even if you’re only looking to get rid of fleas.


When using foggers, you should use only one can per each room, no more and no less. However, rooms can vary in size, and some might just be too large for one can to cover. Because of this you should always check out the coverage of each fogger before purchasing it and compare it to the size of the rooms you’re going to use them with.

Coverage is mostly expressed in cubic meters or cubic feet, depending on your location and knowing how large your rooms are is easy if you know how high up the ceiling is and what size is the surface of the room.

Of course, you also don’t want to use a can with extremely large coverage in an incredibly small room since it might be difficult to air it all out. You should only use them in rooms that aren’t small than half the coverage of the product.


These products can be highly unsafe if you don’t go about using them properly and they can’t be made much safer than they already are. However, there are ways in which some can be safer than others.

For example, a product coming with a detailed instruction manual is always a good thing. It should detail the exact ways in which you can avoid getting harmed by it or harming others with it.

Some products are also less prone to bursting into flames than others and are safer as a result. Shoddy packaging can also lead to a product being unsafe and leaking before use, so make sure the bottle is durably made and has no leaks.


The smell of an insecticide like this can be awfully pungent, and it can linger for quite a while. That can be a huge problem considering that the best way to use them is to fill your house with them. If your house smells horrible for months after use, it might not be a good product.

You should always check out the experiences of other users when it comes to this. See what they say about how smelly the product is and for how long does the smell linger inside the house.

Now that you’re aware of all this check out how our top products measured up.

In-depth Reviews of 3 Best Flea Foggers

Hot Shot 20177 Fogger

The best part about this product is that it is effective almost immediately – it will kill loads of different insect pests, and it will do it in a matter of hours after use. It’s also safer than most due to being non-flammable while also leaving little to no smell. The issue is that it isn’t useful in the long run and that you don’t get a lot of it for the price.
What We Like
Exceptionally safe - not flammable
Doesn’t leave any nasty smells
Works on a wide variety of pests and kills quickly
What We Don't Like
Doesn’t have a lot of staying power
You only get three cans in a pack
The sprayers malfunction at times

Key Features

Effective in the Short Run Doesn’t Stay

The effectiveness of this product can’t be argued with – it will kill not only fleas but ants, spiders, centipedes, crickets and most other insects incredibly quickly. However, its effects will dissipate equally fast, so if you want some long-term treatment, you will have to use it again and again.

Hot Shot Fogger

Plenty of Coverage

In the pack, you get three foggers, and each one is good for a room of up to 2000 cubic feet. This is decent for a product at this price point, and you can use it for larger rooms without any problems. However, if you have a house with more than three rooms you will have to buy multiple packs and considering that it doesn’t last for long, the cost could pile up.

Hot Shot Fogger Coverage

Incredibly Safe

This is a supremely safe product because it isn’t flammable and you can easily leave most of your lights on while it is still in the house. It also doesn’t stick around for too long. The quality of the cans it comes in is suspect though.

Hot Shot Fogger Safety

Leaves no Smell

There’s no smell left after using these foggers, and you won’t even notice that they were used. You don’t have to worry about your furniture smelling horrible after using it.

Customer Reviews

There are a ton of stinkbugs in the area where we live, and they’re a real pain in the butt. So, this was immensely helpful at getting rid of them. We got a full bucket of dead ones just a day after we set these off and they are still dying off a week later. I’m glad it works so well, and I highly recommend it.
I bought this to get rid of the fleas that have been infesting my house since the dogs bring them in all the time. I fogged the house around a week ago, and I haven’t had any issues since, thank goodness. This product works well, and I would recommend it to anyone who has flea problems.
I used this almost two months ago, and the bugs haven’t appeared since then. You should make sure to go over all the rooms in the house for it to be effective – yes, even the attic and the basement. If you don’t do that the bugs will just hide out in the places you missed and return later. If you do it properly, it works well and leaves no nasty smells. I used this to get rid of spiders, centipedes, and some spiders and I haven’t seen them at all for the past couple of months.

Who Should Buy this Product

If you want to see results almost immediately, this is the product for you. It is also quite suitable for people who want a fogger that is safer than most and not flammable or one that doesn’t leave any smells. It works for more than fleas as well, and you can get rid of loads of different pests with it.

What to Watch Out For

If you want something that will work over a longer period and stay effective weeks after use, you should look elsewhere as this product dissipates in a matter of days. You also don’t get a lot of it for the price since only three cans are in a pack. It can be unreliable as well since cans have failed to spray at times.

The Conclusion

This product is great in some regards, especially how effective it is in the short run and how much safer it is than other products out there. The issue is the cost and the fact that it fails to be effective in the long run. Still, we think it is worth the cost because it is more effective than most other products out there.

Purchase this Product on

Black Flag HG-11079 Fogger

You get a lot of cans for the price, six in total, and it is a long-lasting formula that can linger for up to six weeks. What also linger is the horrible smell, and it’s a shame that this fogger isn’t particularly effective at killing most insects in the short or the long term.
What We Like
Easy to use
Lasts for quite a while
Comes with six cans at a good price
What We Don't Like
Not as effective as similar products
The smell lingers for quite a while
Extremely flammable

Key Features

Long Lasting but not Effective Enough

The effects of this product can linger for up to 12 weeks, which is quite a lot. The problem is that it is not good at killing a lot of different things and it barely even kills fleas properly.

Black Flag Fogger

Decent Coverage

Each can is able to cover around 2000 cubic feet, which is enough. That’s not amazing but is quite standard when everything is considered. It does come with six cans in a pack, meaning that you can cover plenty of space with just one purchase.

Black Flag Fogger Coverage

Not Safe Enough

Most of these products are flammable due to how they’re made and the chemicals they use. The issue with this one is that it is more flammable than most, so you should take extra care when using it or even when just handling the cans.

Black Flag Fogger Safety

The Smell Lingers

The product leaves an odor after use, and the manufacturer is at least honest about the smell can remain for a day or two as well, so you should make sure that you’ll be out of the house for a while when using it or you will have to deal with the stink.

Customer Reviews

This did exactly what it was supposed to, and it got rid of all the bugs in my house. I just followed the directions to the letter, and it was easy. It doesn’t leave a foul smell like other chemicals do, so that’s nice. I used it two times already, and it worked each time, which is nice. I will probably use it in the future as well if I happen to need it again.
It works just as it was described. I have a couple of cats that go outside a lot, so they catch a lot of fleas and bring them in. It has been particularly bad during this year, so I got this to deal with it. It got rid of the fleas, but it didn’t get rid of the eggs they laid, so I had to use it again after a few weeks, but that did the job, and I haven’t seen a flea since. It’s a good product overall.
I set these off in every room in the house before going on a month-long vacation, so I wasn’t around to watch them do their magic. However, when we got back from vacation, we found no bugs around the house. Well, no live bugs, there were plenty of dead ones that we needed to clean up, We haven’t had any bug problems since, so I guess it works, and that’s enough for me.

Who Should Buy this Product

For those that want a lot of value for their money, this is the product to get. You get six cans in total, and each can is able to cover a decent 2000 cubic feet. The product is also long-lasting and can work for up to 12 weeks after the initial use. On the surface, this looks like good value for the price.

What to Watch Out For

When you get down to it, this is not a product that is effective enough, and it can’t kill a lot of insects, not in the short run or the long run. It is only effective for a few species of insects, mostly fleas, and roaches and it won’t kill off most of them either. It is also potentially unsafe since it’s extremely flammable.

The Conclusion

Overall, despite how much you get for the relatively low price, this product isn’t particularly worth buying. The reason is that it lacks quality, so it tries to make up for that with quantity. It doesn’t kill insects well, and that is its greatest downfall, even though it has some other flaws as well.

Precor Plus IGR Fogger

This is an effective product that can cover a large area and last for months on end. It also leaves no smells in your house after use, which is a nice bonus. The issue is that it costs quite a pretty penny and the can it comes in is not effective at dispersing the contents inside, so it loses effectiveness.
What We Like
Extremely long-lasting product
Doesn’t leave any lingering smells
Huge coverage
What We Don't Like
Costs quite a bit
Unusable in smaller rooms
The can itself does a poor job at dispersing the contents

Key Features

Effective but Difficult to Use

This is an effective product, there’s no doubt about that, and it lasts for an extremely long time, up to seven months. That’s just in theory since the cans it comes in are of poor quality. They spray badly, and you can’t place it on the floor like most foggers – you have to place it quite high up for it to work well. Even then, it still might not disperse well enough.

Precor Flea Fogger

Great Coverage & High Cost

It can cover a room of up to 750 square feet in size with no issues, which is more than most other products. The issue is that a six-pack of these foggers costs quite a bit more than most others, almost three times more. Also, because of this, it won’t work well in smaller rooms.

Reasonably Safe

While not any safer than most other products of this ilk, it is not more unsafe than them either. You still have to follow the same protocol as with other foggers, but you will have no extra worries.

No Smells Left

Due to its formula this product won’t leave any lingering smells and will dissipate an hour or so after use. You don’t need to worry about staying out of the house for a day or two due to using these foggers.

Customer Reviews

We make a habit of setting off six or seven of these in our house each spring, without fail. They get rid of all the fleas, ticks and other bugs in our house, and it keeps killing them even months after the initial use. We find dead scorpions even at the start of winter, and it’s probably because of this. It’s incredibly effective and long-lasting, and I just love it.
This product managed to kill a ton of fleas, but I was lucky that I read some of the other reviews and heeded their advice. If you have a huge flea infestation, one use is simply not enough. It won’t kill any eggs that remain, and you will have more fleas later because of that. I sprayed all the cracks in my floor and walls with bug spray to get rid of them as much as I could. I also kept vacuuming every day to get them out of the rugs. It took around three weeks to root them out completely. This product helped a lot with that though, so I would recommend it.
I used this in combination with a bug spray, and it managed to eradicate the flea infestation I had completely. It was so bad that I thought I would never manage to root them out, but I did. Now I’ll be more careful and use some anti-flea products on our pets to stop this from happening again.

Who Should Buy this Product

This fogger is ideal for people who need a long-lasting product since this is the best one out there when it comes to that. It will last an astounding seven months, which covers the entire bug season, from early spring to late summer. It is the ideal product for people who don’t want to keep spraying and have large houses.

What to Watch Out For

The largest issues here are the cost and the lack of effectiveness this product has due to the can it comes in. The sprayer isn’t effective at dispersing it properly, meaning that it will mostly stay low to the ground and in the area near it, dispersing quicker than it should. This can be remedied a bit, but it’s difficult. For such a costly product, this is highly disappointing.

The Conclusion

If this product was half the cost that it is, we might still be able to recommend it, but at this price, its flaws are simply unacceptable. The fact that it doesn’t disperse properly is the largest one and makes all its benefits moot. It’s a shame, but we have to say that this product is not worth buying, not at this cost. Wait for a discount, and it might be worth your cash.
