The Best Cockroach Killer To Maintain Your Sanity

Cockroaches evolved with the dinosaurs, and in their natural habitat, they are actually a very necessary insect in the food chain. It is when they invade a house, home or apartment that they become a nuisance. Without any natural predators, cockroaches will quickly overrun any dwelling, and they will particularly flourish in areas that are unkempt with food stuffs left laying about, grease from cooking that is not cleaned, and crumbs that are left on counters or that have not been swept up from the floor. That type of environment is a cockroaches paradise. And before you can kill them, you have to clean up their food source, or they will continue to re-infest the area.

Cockroaches are notorious for their hardiness, so the best cockroach killer in 2022 on this list must be 100 percent effective from the get-go. Price is no object here since pest eradication has no cost limitation. Ease of use will come into play, but the best cockroach killer will be quick and the most effective to rid your house or home of cockroaches ASAP. Just remember, baits and ingredients in cockroach killers are also toxic to kids and pets, so care must be taken to hide baits in places that are hard to reach and hard to get at.

What Are the Types of Cockroach Killers?

Roch killers come in different products and variants and they differ in how they work. Each variant has its own unique features that you can’t expect from others. Sprays can go deep in hidden places, while roach motels have an edge to be safe for children and pets.


Roach killing powders are a fast and effective way to get rid of cockroaches. The powder can be used at any place even at hard-to-reach points. You can pour the powder in between the nest of roaches and they are finished in a few minutes.


Sprays are easy to use and a quick solution for your kitchen safety. Sprays usually attack the nervous system of the roaches and kill them in less than a day. Also, they are handy products as compared to other roach killers and can reach inaccessible places too.

Roach Motels

Roach motels are enclosed boxes that attract roaches into them with no option of going back. These motels offer a safety factor for children as they are not poisonous.

Some other motels attract roaches into the motel having a poisonous substance that kills them right away. It's an effective option but not safe for pets and children.

Roach Gel

Gels emit some strong appealing smell that roaches can't resist. The best part of the gel is that they do not kill the roaches right away, it starts its action when roaches return to their habitats. When they are killed in their habitats, they become food for others, this creates a spontaneous process and the other roaches get finished too.


Foggers – also known as bug bombs – are can-shaped roach killers, containing a poisonous gas. Upon activating, the foggers leave a harmful gas that gets into inaccessible places, covering the whole room. Foggers use pyrethroids, which slowly fail the roach's nervous system and slowly kill them.

Before you use foggers, make sure the edibles, dishes, and other utensils are covered. Also, leave the room for at least 4 hours to make the air go back to normal.

Factors Should You Consider Before Buying a Cockroach Killer

Effectiveness On Pests

When choosing a cockroach killer always pay attention to what pesticides it is using and on what insects they are effective. Different killing products work differently and have their specific targeted insects.

The glue sheets can catch every size of an insect, including rats, lizards, ants, and roaches. Roaches have some sort of good immunity, so the roach killers use high-potency pesticides that can even affect your pets and children.

Safety Factors for Pets and Children

Safety matters first! Make sure your family and pets are in a safe area before starting the operation. The gels and baits are attractive to kids and pets due to their bright colors. So make sure you keep an eye on your kids.

Some children-safe options are available but they are not that effective. You can use those roach killers if the problem is not that severe.

Length Of Efficacy

Length of efficacy means how long the roach killer will produce the desired results. Most of the roach killers produce results for 1-month at a minimum- the period can be as long as 2 years.

Type Of Bait

There are two types of baits commonly used to attract and kill roaches. Fipronil is used for some baits and some killing products use hydramethylnon.

Fipronil uses poison and works fast! Roaches can't take a single step after consuming it. It uses sugar to attract and fipronil to kill them on the spot.

On the other hand, hydramethylnon uses a slower process of killing! They attract and lure the insects to eat. When they finish, they get back to their habitat, slowly lose their nervous system, and it's over. The process doesn’t stop here, the killed roaches now become the food of other roaches, and kill them too! The spontaneous process kills the whole community in your home.

What Do Professionals Use To Kill Roaches?

The high-level insecticide used by professionals to eradicate roaches is Indoxacarb. This substance is also found in gels. Due to its high potency and effectiveness, it is recommended over all other insecticides.
