A Guide to the Best Cockroach Killer

Cockroaches have existed since the era of dinosaurs and have, in no way been beneficial to anyone. These horrible creatures spread diseases and look creepy and infest your house in swarms.

It is no wonder that humans have come up with varied ways to get rid of these infernal pests.

Instead of using gel baits you can also use a trap or spray. But traps are tricky and will not target the entire population.

And the sprays are a temporary solution as well. In case, you are wondering about how to get rid of roaches without an exterminator, here is a way for you.

So if you are searching for the best cockroach killer in the market, I will be happy to help you reduce as much of their population as possible.

Among the several methods that I have used (and I have used a lot), the best cockroach killer would be the Advion Syngenta Cockroach Gel Bait.

It is easy to apply and works on nearly all roaches.

Most, like me, do not have the patience to analyze the particular species that has infested our homes.

We end up generalizing them under roaches, altogether. So it is better to get an all-in-one product.

And this is a good choice if you have been suffering from an infestation for a long time and the cockroaches have developed a resistance to your products

#1. Advion Syngenta Cockroach Gel Bait (Best Roach Killer)

As if the very notion of a cockroach was not scary enough, they come in several shapes and forms.

If you are battling a varied collection of these pests at once, here is your solution.

This product, counted as the best roach killer in this list is most effective for more than one species.

Roaches are known for their pestilence above all else.

You can hit them with even the vilest of poisons and they wouldn’t even have the decency to die.

This Advion Roach Gel Bait is a unique formula that is known for its excellent performance.

You can just inject this into the cracks of your door and windows and rest assured that your roaches will bite. The composition in this bait is non-repellant as well.

There are numerous varieties of these pests and each come with a fresh new horror.

Whether it be the dreaded German Roaches or the American or Asian ones, this bait is adept at killing them all off.

In the vast plethora of roaches that this gel is capable of exterminating, are the smoky-brown roaches, the brown-banded roaches, the Australian roaches, Asian roaches, American and German roaches.

Often the greatest deterrent of using any kind of insecticide is the unwanted danger they pose to our pets.

However, if you use this gel bait in the prescribed manner, it would be perfectly safe for them. It is perfectly capable of killing the direst of infestations as well.

For a moderate one, you merely need around 1 to 3 drops 10 linear feet apart. For a more severe situation, you will need a higher dose of 3 to 5 spots.

Cockroaches know how to evolve and that is how they survived the long eons to grace us with their existence.

Thus, the repeated use cockroach killers lead them to adapt and grow resistant to its effects.

This non-repellant formula is made to kill even the toughest of infestations and leave your house safe and cockroach free.

However, the product will expire in two years and so you will have to use it up before that.

But on the other hand, if you follow the prescribed process, the contents would not last more than two years either.

Feature We Like
  • Non-repellant.
  • Deals with severe infestations.
  • Kills the toughest species of roaches.
We Dislike
  • The product expires in two years.

#2. Boric Acid Roach & Ant Killer

If you find yourself fighting in turns, a cockroach, and an ant infestation, this Boric Acid Formula serves both purposes equally well.

For an easy and fast removal of a roach infestation, this is your bottle of bliss.

Cockroaches infest our homes and when you kill them off, ants swarm the bodies and this culminates in an ant infestation.

Wouldn’t it be easy if instead of juggling between a couple of different insecticides for different pests, you get one that serves both purposes?

This cockroach killer is a solution of boric acid that serves to remove all kinds of pests from your home.

Other than roaches and ants, it further works on flies and most other insects as well.

This solution is known for its potency. It is easy and works fast on the roaches as well.

It will remove most of the infestation. If you use regularly, then you will be able to have a cockroach-free home soon.

Because it is not a gel bait, the application is not as neat. You have to make sure that you cover all the surfaces properly to reach every single cockroach in your home. But being an acid solution, the work is effective without question.

Feature We Like
  • Versatile.
  • Strong boric acid solution.
We Dislike
  • Application can be a bit messy.

#3. Invict Gold Cockroach German Roach Control

If your house has been undergoing an infestation for a long time and you’re wondering about how to get rid of German roaches, this is the product for you.

Even if that does appear a bit limited, it is satisfactorily merciless on those roaches.

Household German roaches are stubborn and grow accustomed to any bait that you use for a continuous stretch of time.

While that does speak highly of them, it is not so great for us.

And that is why cockroach killers have to be used alternately to fool those pests.

If you are bored with the declining effects of your previous roach killer, it is a good idea to switch it with the Invict Gold in-between.

This gel bait contains the active ingredient, Imidacloprid, which is efficient at exterminating even those roaches that do not take the bait easily.

The container comes along with the plungers that help in application. You can just squeeze a couple of spots in between your furniture and doors or windows and forget about it.

The roaches will take the bait soon enough and you will find dead bodies in swarms all over your floor.

However, this product is limited to German roaches only. It won’t work as well on any other varieties.

So I would recommend this, only if you have identified the species that plagues your home to be the German variety and not just an amalgamation of different kinds of cockroaches.

It is often not possible to examine the cockroach species to be of any particular kind.

They all are brownish-black, have wings and creep out of corners. So in most cases, I wouldn’t recommend this product.

However, if you have somehow managed to identify the kind, it is one of the most effective products in the market.

It is probably the best German Roach killer I have ever used. In case you have a good guess but are not sure, you can replace your original roach killer with this every other day, just to check if it works.

Feature We Like
  • Effective when used alternately.
  • Easy to apply.
  • Great on German Roaches.
We Dislike
  • Works greatly only on German Roaches .

#4. Dupont Advion Roach Gel Bait

If your bait victimizes just one cockroach, it doesn’t really have much of a point.

Baits are meant to take out the entire infestation with maybe some exceptions.

So if you are tired of reapplying your baits, again and again, you should probably try this one out.

If a cockroach dies as soon as it consumes the bait, there is no guarantee that the other roaches will find the baits and die as well.

However, the Dupon Advion contains an active ingredient called Indoxacarb that works to cause a delay in the death of the cockroach.

The cockroach returns to its nest and effectively poisons the other roaches. This helps to take out the entire infestation in a few days, instead of eliminating them one by one.

One of the primary qualities of the best cockroach killer would be to kill the hardiest of species.

And some varieties like the German cockroach, the American and the Brown-banded cockroach are pretty hard to get rid of.

This poison is designed specifically with that purpose in mind. The constitution of a powerful bait matrix works to kill even the most bait-averse roaches.

It is non-repellant and bears the maximum chances for consumption.

It can be used both indoors and outdoors. So, if your roach problem stems from your drainage, you can easily apply the outside your house as well.

Further, this is usable in all kinds of environments including residential and industrial.

However, the bait does not draw the roaches to itself. You have to rely on the chance that the cockroach will come across it and consume it.

This, though, is highly probable if you apply it at the areas that roaches seclude themselves in.

This is a really potent cockroach killer with a couple of unique features on top. It is probably one of the best in this list.

However, the problem is when the as it kills the infestation in the nest itself, it is difficult to discover the dead bodies. So that might lead to an ant infestation in the future.

Feature We Like
  • Poisons the entire infestation.
  • Works on several species.
  • Can be used outdoors.
  • Kills bait-averse roaches
We Dislike
  • The roaches are not drawn to the bait .

#5. Bayer Maxforce FC Magnum Roach killer Gel Bait

Often cockroaches outsmart the humans and leave the baits alone.

However, there are ways to overcome this hurdle as well.

Wait for this bait, consumption is not actually necessary for it to work on the roaches.

Leaving the baiting up to chance is often ineffective.

Unlike rat poisons, many cockroach killers are not built to attract the roaches and entice them to eat it.

More than often, even if you place it at strategic locations, the roaches will merely brush against the bait without actually consuming them.

However, this gel bait is potent enough to work with just a touch. That allows it to kill a larger number of roaches than just a regular one.

The bait remains effective for a longer period of time. Most gel baits expire and are ineffective on roaches after a year of application.

This, on the other hand, works just as well even after it has crusted into a dried chunk.

So don’t be disheartened and pick it out in a month or two. If it hasn’t handled your infestation till now, it will.

The bait is pet safe, which is a major consideration for all pet owners. However, you have to follow the directions meticulously for it to be so.

The only downside is that, before application, you will have to clean and dry out the area if it is dusty, to begin with.

However, apart from that, it is an excellent product that wins out in its longevity and method of killing the roaches. It is more liable to work that most other baits as well.

Feature We Like
  • Fast efficient bait.
  • Is effective for a long time
  • Kills almost the whole infestation.
We Dislike
  • Can’t be applied in dusty areas .

How to Choose a Cockroach Killer?

Roach baits are poison and can potentially harm your pets and kids. However, with proper application and purchase, this can be avoided. So firstly, keep the safety of your pets as a priority and buy accordingly.

Secondly, cockroaches should be drawn to the bait for it to work fast enough. If the baits are not enticing enough for the roaches, then it will be ineffective and pointless. Some baits work on just contact and don't have to be consumed at all. These have a higher chance of working faster and killing a large number of roaches.

Thirdly, it is an advantage if instead of killing the roaches instantly, it works as a slow poison that kills the insect after it has gone back to its nest. This poisons and kills the entire infestation and makes your job easier.

A cockroach killer should be able to work on all types on roaches, instead of a just a particular species. This way, you don’t have to identify the species of infestation and kill them all.


Finding the best cockroach killer is more of an act of desperation than anything else. Like several people, if you do not want to employ the pest control services at first, you must have gone through several poisons and traps. However, the key is to research properly, so that the product you use is both safe and effective. That’s all for today.
