Hot Shot Indoor Fogger Review

You do not need to read many Hot Shot Indoor Fogger reviews to see why it is one of the best products on the market. With four cans in the pack, as well as an odor neutralizer, this is a great tool. It will instantly exterminate even the heaviest of cockroach infestations from your indoors area. Each can contains 2 ounces (56.5 grams) of fogger, which is enough to treat up to 2000 cubic feet (56.6 cubic meters) of enclosed space.

Like other good roach killer bomb and fogger products, the Hot Shot Indoor Fogger easily and successfully penetrates all cracks, crevices, nooks, and carpet fibers. This allows it to effectively exterminate hidden roach and bug nests, eggs, and larvae. Thus, it brings an end to entire pest populations at once.

More than just a one-time solution, the Hot Shot Indoor Fogger has a lasting effect of up to two months. This will guarantee that you will be seeing no more of the nasty pests. It will also give you the time to take preventive measures against future invasions. Even better, the Hot Shot Indoor Fogger works on more than just roaches.

The product can be easily used in any enclosed indoors space: houses, apartments, barns, attics, basements, boat cabins, campers, crawl spaces, garages, trailers, storage spaces, sheds, and more. The Hot Shot Indoor Fogger could even be a great roach bomb for cars and other such vehicles. Keep in mind that the smaller cubic area will mean that you will need to give the area extra ventilation and cleaning after the fact.


Raid Concentrated Deep Reach Fogger


What we like:

What we don't like:

  • Online purchases tend to cost significantly more than buying in a local store
  • Intended for crawling bugs rather than fliers
  • Does not treat as wide of a spectrum of pests as other products

Raid Concentrated Deep Reach Fogger Review

It should be no surprise that this Raid Concentrated Deep Reach Fogger makes an appearance in our Top 3 list. As you would expect from a Raid product, this Concentrated Deep Reach Fogger truly goes deep. There is no crack, crevice, or nook that this fogger will not reach. This guarantees 100% effectiveness, a fact which is backed up by the many positive customer reviews out there.

Additionally, this fogger leaves no wet residue behind. This is a great plus, as anyone who has ever used most other roach fumigation tools will testify. With this item, you can not only rid yourself of roaches but also of a significant part of the cleaning that comes afterward. That is, of course, if you have followed the product’s instructions completely.

The pack comes with three cans in it, which is enough for most apartments, houses, and residential areas. Still, it should be noted that if you expect to need more than three cans, you might want to pick up another product – or a second pack.

This Raid Concentrated Deep Reach Fogger is a good choice for use in cars and other vehicles. Remember to clean the treated area extra diligently afterward. With its strength and coverage, this fogger is definitely a worthy candidate for any “best of” list. It does not have as wide of a spectrum as other foggers. It is also less effective against fliers than crawling insects as it specializes in crawlers.


PCO Products Pyrethrin Fogger


What we like:

What we don't like:

  • Quite pricey

PCO Products Pyrethrin Fogger Review

If you are looking for a good bug bomb or roach fogger, do not skip over this PCO Products Pyrethrin Fogger. You do not have to read many reviews to see that this PCO Products item deserves its spot in our Top 3. Its active ingredients are pyrethrins, piperonyl butoxide, and dicarboximide. These give it exceptional power and reach when bombing any enclosed areas.

No matter what area you are looking to de-roach – your home, storage area, garage, crawlspace, barn, any commercial building, restaurants, warehouse, school, hospital, and so on – the PCO Products Pyrethrin Fogger is a highly effective solution to any roach problem.

One can of this product is enough to cover 5000 cubic feet (141.5 cubic meters) of enclosed, unobstructed space. This fact alone shows this product’s power. Roughly speaking, this means one can treat a room that is 25 feet x 25 feet (7.6 meters x 7.6 meters) with an 8-foot (2.4-meter) ceiling.

Aside from roaches, this product works wonders on other insects as well. This includes fleas, ants, spiders, weevils, and any other species of flying insect.

Other Products to Consider

Raid Fumigator

The Raid Fumigator comes in a pack with three 0.35-ounce (9.92-gram) bottles. The unique consistency of the smoke allows it to penetrate all hidden areas behind walls and surfaces. The fog is dry and leaves no oily or moist residue behind. Instead, it leaves a clean and fresh scent. This product answers the question “Do roach foggers work?” with a resounding “Yes!” Still, there are stronger and more effective foggers out there, which kept this product out of the Top 3.

Hot Shot No-Mess! Fogger

Not many Hot Shot No-Mess! Fogger reviews need to be read to convey the effectiveness of this product. The fog created by this fogger stays airborne for a long time. This allows it to effectively kill flying insects and still reach those crevices and cracks in your home to deal with roach nests and other crawlers. As a dry fogger, it is safe and easy to use but not as effective as some other products out there.

Durvet No-Bite Multi-Pest Indoor Fogger

The Durvet No-Bite Multi-Pest Indoor Fogger uses a three-insecticide formula which allows it to effectively kill a wide range of insects in addition to roaches. It comes as a three-pack. Each individual 6-ounce (170-gram) fogger can treat an area of 6000 cubic feet (1828 cubic meters). The large size of the can does make it less practical for smaller spaces, thus reducing its versatility.

Bengal Concentrated Flea & Roach Fogger

The Bengal Concentrated Flea & Roach Fogger almost made it to the Top 3 thanks to its wide range and significant coverage. In addition to coming in a three-pack, this fogger is a testament to Bengal’s quality. The instructions of this particular product are a bit dodgy, however. There are some significant omissions about the ingredients, the consistency of the smoke, and the preventive measures that need to be taken.

Spectracide Bug Stop Indoor Fogger

There are plenty of Spectracide Bug Stop Indoor Fogger reviews that can be read online but few actually give this product the justice it deserves. This fogger kills all common household bugs on contact, leaving no messy residue behind. It does not have the unpleasant odor of so many other foggers and bug bombs. The effective coverage area of this fogger is smaller than other foggers of the same class. That makes it better suited to smaller spaces or cars than larger spaces.

TAT Fogger

This TAT Fogger is great for all kinds of enclosed areas. It can be used to treat most common household bug infestations. In terms of raw power, however, there are stronger products on the market right now.

Black Flag Concentrated Fogger

Consider the Black Flag Concentrated Fogger if you do not have simply a roach problem, but rather a German cockroach problem. This six-pack kills most common household insect pests, including those pesky German roaches. It also leaves a fresh scent behind instead of a stinky odor or messy residue. The effects last up to 12 weeks, giving you time to set up additional preventive measures. It is not as effective for flea control, however, and the trigger mechanism can be a bit tricky to use.

About Cockroach Foggers and Bombs

A Quick Breakdown of Roach Bombs and Foggers

Total release foggers, also called roach bombs, are devices that contain insecticides and aerosol propellants. After you set them in the center of a room and activate them, they spray all of their contents up into the air and the droplets settle around the room killing anything that comes into contact with them.

Unlike roach bait gels, they do not poison roaches and let them remain alive long enough to contaminate the rest of the nest. Instead, much like cockroach sprays, they simply kill anything they come in contact with instantly. However, unlike sprays, foggers require that you leave your home for hours at a time. When you return, you’ll need to air out the house and thoroughly clean all the surfaces in the room where you set off the roach bomb. It can end up being a long process and a lot of work.

What this means is that roach bombs are not really a good tool for frequent use or to act as a preventive measure. They don’t reach into many cracks and crevices where roaches hide. They can have residual effects if you don’t clean them up, but fogger residues are dangerous for human and animal health. So, if you want to make sure that your house or apartment will remain bug-free in the future, you will need some other preventive tools such as roach baits or gels.

Still, roach foggers do have their use. They will kill any cockroaches that happen to be outside of their hiding places when the bomb goes off. This is useful in severe infestations when hiding places have been filled up.

Ingredients of roach bombs

Roach bombs and foggers can have a lot of different ingredients. Generally, these ingredients are different types of pesticides, since their goal is to kill every living roach, bug, egg, or larvae in the area. There are dozens of different pesticides out there. That is why we will not even try to go over them all in a simple article like this. Suffice it to say that the reason why there are so many different types of active ingredients is that different bugs are resistant to different types of chemicals.

In fact, even among cockroaches, different types of roaches can live and breathe in areas that have been heavily fogged with pesticides. The most obvious examples are German roaches which seem to be able to survive anything. Well, not quite. Even German cockroaches have met their match in certain products.

Roach Bomb and Fogger Buying Guide

Getting the right roach bomb or fogger can be tricky but is very important. Even though roach bombs and foggers work by just gassing everything indiscriminately, there are actually a few variations you need to consider when buying one. Going through each question carefully is an essential part of making the right decision. So, let’s go over the questions you should be asking, one by one.

Are you dealing with fliers or crawlers?

Most bug bombs and foggers say that they work on all kinds of common household insects. That is usually true – they do. Most are still better suited for fliers, though, and are rarely lethal for crawlers.

The main active ingredient in most foggers is pyrethrin, which is less effective against insects such as ants, cockroaches, and bed bugs than it is against flying pests. Look for non-pyrethrin insecticides but keep in mind that cockroaches can and do develop resistance to multiple types of insecticides simultaneously. 

Which type of bug is the bomb intended for?

Similar to the above consideration, different active ingredients will make them better suited for different pests and insects. 

What are the dimensions of the target area?

Always read the label. Manufacturers of bug bombs and foggers know the amount of space their products will fill and they put it on the label. Never use more devices than the label specifies. Improper use of total release foggers is the main cause of illness, injuries, and death resulting from their application.

How much does it cost?

This may be redundant but as with almost all other products, price matters here as well. Even if you are not on a budget, bug bombs and foggers may need to be purchased multiple times or in larger quantities (if you are treating a very large area). So, while you should not compromise on quality, it is good to not overspend either.

Looking at the price alone is not a good way to measure things. Consider the volume in cubic feet (or meters) that the fogger covers. Calculate the ratio of volume against price to get a clear picture of how much this fogger is really going to cost.

Who makes it?

As with pretty much every other product out there, branding matters here, too. Some brands are famous for their high-quality bombs and foggers while others are notorious for their sub-par products. Some of the best brands to consider are Raid, Black Flag, Hot Shot, Durvet, TAT, Spectracide, Bengal, and PCO.

Useful Information About Cockroach Bombs and Foggers

When it comes to roach bombs and foggers, the first question that comes to most people’s minds is: “Are they safe for us?” The answer to that is: “Well… no, not really.” Of course, if you take the necessary precautions and read and follow all label instructions, you will be safe. If inhaled, the active ingredients in foggers are dangerous for humans and other mammals. The aerosol propellants used to get the insecticides into the air are flammable and can cause explosions. Their danger is a huge part of the reason why people with roach problems often avoid foggers, choosing other anti-roach products instead. This is also a common reason why some choose to call an exterminator to help them fight these pests. 

One additional reason is that foggers and bug bombs can simply be tricky to use. They take a lot of work, effort, and are not really fool-proof. Furthermore, they are often ineffective against cockroaches. While we will go over how to use roach bombs and foggers below, the conclusion that many people reach is that there are other products out there that are simpler and safer to use.

Of course, all this does not mean that roach bombs and foggers do not have their uses. They can be used as part of an integrated pest management plan in conjunction with other tools. We understand that if you have a really bad infestation, you may even consider using a flamethrower or an actual bomb. Fortunately, most of us never have to face that level of infestation. Even more fortunately, there are some great foggers (and other treatments) on the market that can come to the rescue. So, leave that flamethrower in storage and try one of the foggers in this article instead.

Usage Tips for Roach Bombs and Foggers

Using a roach fogger is not easy or pleasant. Pesticides are toxic. They should not be inhaled by mammals or birds and should not be allowed to settle on fish tanks. To that end, it is very important to follow the instructions on your roach bomb or fogger to the letter.

But, to give you an idea of what you are in for, here are some quick points to follow.

cockroach bomb use


  • Pack up and remove all food, plants, children’s toys, pet toys, and pet beds/cat towers from the area before fogging. Put all of the dishes away. 
  • Rearrange the furniture so that there are as few obstacles for the smoke as possible, if necessary. 
  • Cover all upholstered furniture or other pieces that are difficult to wipe down.
  • If there’s a chance that there are insect eggs or larvae inside your upholstery, let the furniture get fogged. If you can’t easily clean them after fogging, cover them with a sheet or blanket for at least a month to give the pesticide a chance to dissipate.
  • Wear breathing masks and protective clothing. A mask, goggles, rubber gloves, and a nylon protective coat should be in your arsenal before you even think of releasing a bug bomb in your home.
  • Keep foggers and bug bombs at least 6 feet away from ignition sources, turn off pilot lights, and unplug any device that can spark. A fiery accident is the last thing you want in your home or storage space.
  • Make sure all pets and family members are out of the house.


  • Leave the area while fogging.
  • Do not re-enter until the fogging is complete. The label will specify the amount of time you need to stay away.


  • Air out everything after the fogging has ended. You should let the space air out for at least one hour.
  • Thoroughly clean surfaces.

Clean everything!

Every hard or soft surface should be properly cleaned after the fogging. This is still true if you used a dry bug bomb which leaves no oily, moist residue behind.


Remember, roach bombs and foggers are a final measure and should be used as part of an integrated pest management approach. They are not something to be used after seeing just one or two roaches in your bathroom at night and not as the only method. They are also not preventives. Sanitation and exclusion are critical.

Depending on the severity of your infestation and the number of obstacles, even the best foggers may need a repeat performance. Keep in mind that it will only work on roaches that are out in the open. Despite claims of “deep reach”, the aerosols just don’t penetrate into cracks and crevices. You will need to complement your fogging with gel baits, traps, and/or sprays.

The Top Three

So, to wrap things up, here are the top 3 best roach foggers and bombs on the market right now:

  1. The Hot Shot Indoor Fogger comes in a four-pack. It is effective against all types of common household bugs. If the necessary precautions have been taken, it can be used in an enclosed area, residential or commercial. It is a rather pricey product, but that comes with its quality.
  2. The Raid Concentrated Deep Reach Fogger specializes in exactly what its name suggests. It reaches as deep into your home’s cracks and crevices as needed to exterminate every last larvae and egg that may be hiding there. It does not do as well with fliers, so keep that in mind. But that is not what this product specializes in, after all.
  3. The PCO Products Pyrethrin Fogger can eradicate all manner of insect pests from virtually any enclosed area of the appropriate size. This wide-range, multi-purpose bug bomb has an impressively deep reach. This allows it to go into the deepest cracks and crevices while still having a strong effect on flying insects.

Do you know what is the MOST penetrating fogger is? I remember using some around 12-15 years ago and there was dead bugs about 50 feet out in the parking lot. My house is drafty but I’ve never had any bug bomb work as good since. I deal with alot of hobo spiders and black widows where I live. Thank you
