how to kill roaches: photo

People have long fought cockroaches, that’s why there are all sorts of products available on the market. Here you'll find 12 best roach killers: poison baits, traps, liquid substances, sprays, and sterilizers.

Nowadays, gel baits are the most popular Roach Killer as the mixture of poison and attractant triggers chain deaths of the insects. They gather to feast on the bait, consume it and die slowly. The insects feeding on their corpses die too.

Table of Content:


Before letting you pick a specific product, let us remind you the principles of functioning and the differences between various roach killers:

  • Poison gel baits and gel bait stations never kill their victims instantly, they eliminate the entire pest population due to the fact that the cockroaches spread the poison with their kin rather than merely consuming it by themselves.
  • Sticky glue traps can only help eliminate trapped pests. You’d better use it as an additional treatment and monitoring measure.
  • Killer sprays finish off only those pests that were directly affected by it.
  • Boric acid killer tablets exterminate pests at an extremely slow pace (as they poison and dehydrate them) yet they manage to eliminate the entire population. The entomologists believe that boric acid is one of the best non-toxic and one of the most human ways to eliminate cockroaches. Moreover, it is cut-rate and affordable.
  • IGR products sterilize adult and stop the larvae growth. The population will die out very slowly. This type of treatment is recommended to be used as a complementary measure.

Its rating is 4.5 out of 5 stars, and there are more than 9000 customer reviews. No rival product has so much feedback.

The active ingredient is this bait is Indoxacarb, 0.6% which attracts and then kills the roaches. You should know, this chemical substance has an expiry date of 2 years after the manufacturing date. The pack will hardly last longer, though.

The manufacturer recommends applying 0.5 g dozes of gel 10 ft apart from each other. 3-5 such dozes will suffice even for the most infested house, and a regular infestation requires 1-3 drops of this gel. The poison exterminates a dozen of different types of insects, including the most spread types of cockroaches.

91% of customers claim that this product is useful; therefore Advion can be called the best roach killer. Consumers also state that using this poison 3-4 times per year is enough for fully controlling a cockroach infestation at home. Most of the insects die within a week. It is also mentioned that this gel needs to be hidden somewhere inaccessible for pets and small children and should never be placed near food.

Toomuchstuff was even able to discover the best way to apply the substance: “I did not apply it as was recommended. I don't like having poison applied to surfaces. I took bottle caps and plastic contain er covers and put the Advion in them and put them on the surfaces where I had seen roaches scooting about. In about a week, I noticed a decline in numbers. I threw away the baited bottle caps and replaced them with fresh baited caps. I did this weekly for about two months.

3 Dupont Advion Cockroach German Roach Pest Control Bait Stations Used By All The Pros!

Dupont Advion Cockroach Bait Stations: photo

This Dupont Advion bait is already packed in small plastic traps. Customers in the comments section claim though that this kind of protection is not sufficient for kids and pets. There have been cases of dogs swallowing these traps (they are somehow attracted by the bait) and of kids playing with them like they play with toy houses. In spite of this, the customer rating of this product is as high as that of the previous one, and the price is even lower. it is ~$7.03.

The range of gels available on the insecticide market is very wide. Advion has half a dozen rivals which are very similar, and the only difference is the chemical composition and price. Let’s take a short glance at the main products available on the market.

Combat Max Roach Killing Gel, 60 Grams (2-pack)

Combat Source Kill Max Roach Killing Gel: photoIts price is ~$19.89 (2-pack); customer rating is 4.3 out of 5 stars. This thick tube of gel is very affordable. Unlike Advion, it is only supplied with one poisonous stick. It is applied the same way, the bait is to be replaced monthly. Many users are confused by the instant drying of Combat, but experienced customers claim that gel works even when dry unless it dried inside the syringe (you’ll have a hard time uncorking it).

Invict Gold Cockroach German Roach Control Gel Bait 4 tubes w/ plunger (35 grams per tube) 

Invict Gold Cockroach German Roach Control Gel Bait: photo

Here’s another product. It is also supplied with 4 tubes 35 grams each, and it costs ~$23.37 Invict’s appearance is very similar to that of Advion. But frankly speaking, this product is made by a well-known manufacturer on the insecticide market. the important thing about this killing gel is that it is not supposed to be used for exterminating insects, other than German roaches or cockroaches. They are Imidacloprid 2.15%, the active chemical, is guaranteed to eliminate them.

Both the manufacturer and the customers warn that every user absolutely must read the label before using the gel. 88% of customers consider Invict Gold useful.

Best Roach Bait Stations

This product is well-known, it looks like plastic pucks with 4-8 entrances and exits for insects which, being attracted by the bait, run there, feed there and die along with their mates. These things used to be more popular than gels. They are not easy to place somewhere inaccessible, but kids and pets will have a hard time taking the poison out of the small plastic box. The customer rating of bait stations is substantially lower than that of gels!

The highest-rated (4.0 out of 5 stars) product is Combat Roach Killing Bait, Large Roach Bait Station, 8 Count. This set of 8 stations costs ~$11.15. It is obvious that the target audience is young parents, as even the name of the product mentions that it is “child-resistant”. What else do you need to know about Combat? It exterminates both small and large cockroaches of different types, doesn’t require any special installation and exterminates its victim within hours. This is one of the fastest products besides the instant ones.

Combat Roach Bait Station: photo

Customers claim that Combat Bait Station can also help get rid of water bugs and "palmetto bugs". Despite unclear instructions, you needn’t use all 8 stations simultaneously: everything depends on the dimensions of the room and the degree of infestation. Of course, a single station won’t be enough even for the smallest room.

Surprisingly we have found dozens of comments stating that Combat eliminates the cockroaches in 1-2 nights, which is fantastic. We have also encountered such comments, as "Combat Roach Bait Station: Not working in my house. I placed the 8 stations inside my house 3 weeks ago and they did not liquidate any roaches so far".

Best Roach Traps

Traps are rated next in terms of popularity and effectiveness. As a rule, sets of tiny traps are very cut-rate, with one interesting exception.

Black Flag HG-11020-1 Roach Motel Insect Traps, Case of 12

This product with the sarcastic “Roach Motel” name costs ~$25.99. It is very popular with customers. Black Flag was rated 4 out of 5 stars. This is a set of 12 traps, each of which lasts 4 month. The cool thing about it is that the dead cockroaches disappear in this “motel” and you don’t get to see their corpses. Many women (and even men) are merely afraid of dead cockroaches: they are disgusting not only to touch but even to look at.

This motel welcomes not only cockroaches but also aquatic beetles, spiders and even scorpions (which is a big plus for the residents of the southern regions).

Black Flag Roach Motel Insect Trap: photo

The idea of "Black Flag" is very simple. Cockroaches are attracted by an attractant inside the box, and they cannot get out, and thus they die of hunger. In addition, the inside of the box is designed in such a way that the insects get injured when they attempt to get out. The effectiveness of the system is confirmed by the dozens of comments from real customers.

Some of the users were able to find weak spots of this motel, though: “The downside to this product, at least in regards to American roaches, is that the trap alone is not enough because 1) the large roaches can live up to a month without food, and 2) they will tear body parts off to get out of this trap long before they die of starvation. Since it was evident that the roach would eventually rip off enough body parts to escape, I got the bright idea to spray the roach with an insecticide and then replace the trap with a fresh one. This resulted in wetting the adhesive, allowing the roach to free itself and try to scurry off. I ended up having to squash it with a broom. So be aware that these are single-use traps for large roaches”. Read other customers’ reviews to decide whether it is worth buying.

Glue traps, like Trapper Max Glue Traps 12 Glue Boards Trap Mouse Bugs Insects Bed Bugs Spiders Cockroaches NON-TOXIC are also simple to use. For only ~$9.84 you’ll get a set of 12 cardboard traps covered with adhesive tape on the inside. No hi-tech or innovations are involved, this is a traditional method. The gluey area is small: only 4.5x6.5 inches. The manufacturers assure users that this will be enough to catch dozens of insect. There are no complex attractants inside the Trapper Max though the chocolate smell of the glue hints that some aromas were nonetheless used. It’s funny that this thing can be called a transformer, as the box can be opened and expanded thus making the trap open and closed.

The customers recommend setting up the trap carefully so that you don’t get your finger in the glue. The most meticulous users even recommend not relying on such traps as a universal product against insects. According to them, you have to first destroy the nests of the insects (which Trapper Max surely isn’t capable of) if the cockroach infestation instead of implementing some aesthetical measures.

Price: ~$9.84 Check the current price

Another cheap and simple roach trap is Trapper Insect Trap (Great for Bed Bugs, Spiders, and Cockroaches) which includes 90 traps. A single set of 90 (!) traps costs ~$17.19. This is much cheaper than Black Flag and Trapper Max. These traps, though, are disposable and too simple. But does this really matter? Effectiveness is the main thing here. You won’t find any attractants or chemicals (you can buy some compatible attractants still). The trap is made of mere cardboard adhesive strips 7x3 inches in size. If you wish, you can divide a single strip into three miniature traps which can easily be located in inaccessible places. When working, Trapper Trap is supposed to be shut, but after that you can open the lid and check who got trapped. Turns out that this device is not only a trap but also is a means of monitoring a cockroach population.

Customers praise the product in the comments section. The remarks were made only by those who were hunting fleas and other insects and weren’t satisfied by the headcount caught. It works perfectly for cockroaches, though. However, in order not to hesitate, you can read all if the customers’ feedback and see for yourself whether it’s worth buying.

Roach Spray - the Fast Way to Eliminate  Roaches

Let’s now move on to the most traditional product used by our parents. Sprays have really proven themselves over time!

Raid 17.5OZ Cockroach Killer

This product costs ~$8.95 and is in demand. Its Amazon rating is 4.1 out of 5 stars. It works as fast as possible and kills the insects once it comes in contact with them. The smell of the poison disappears quickly which is another advantage. The smell of Raid Roach Killer isn't that bad though as it contains lime aroma. The main peculiarity of this killer is that it is also highly effective against ants. A “2-in-1” spray at a low price is what makes it so popular.

Raid Roach Killer: photo

Such express-killing has its disadvantages too. It has been proven that chain reaction doesn’t work with this spray, i.e. when you spray it over 10 cockroaches, you will exterminate exactly 10 cockroaches. They won’t reach the nest and contaminate 100 other insects. That’s why don’t waste it and spray the most infested spots with it.

Raid 17.5 OZ Roach Killer is especially popular with the farmers as they have to get rid of all types of insects: ants, flies and mosquitoes. Frankly speaking, we weren’t able to find a single negative review of Raid.

Price: ~$8.95 Check the current price

Ortho Insect Killer: photo

Another universal poison is Ortho 0196410 Home Defense MAX Insect Killer Spray for Indoor and Home Perimeter, 24-Ounce (Ant, Roach, Spider, Stinkbug & Centipede Killer). This spray doesn’t use gas: this is simply a poisonous liquid which needs to be sprayed with an aerosol. It eliminates and repels over 130 species of insects (most often it is bought against ants, roaches, and spiders)!!! The price for Home Defense is very affordable; it is ~$12.16 for a 24 oz bottle. This mixture not only acts as an instant poison, but it also serves as a repellent.

Other Methods of Exterminating Cockroaches: Tablets and Insect Growth Regulator

If you don’t trust modern chemistry, or you feel pity for cockroaches to be killed, we’ll tell you about the oldest cockroach control product, which is 80 years old. We’ll also devote some time to the sterilizer which doesn’t cause the death of an insect but makes the females infertile and thus stops roaches’ breeding.

Harris Roach Tablets

They sell old anti-roach tablets on Amazon, Harris Roach Tablets 4 oz for ~$6.49. The rating of this product is 4 stars, but despite this rating 72% of customers consider these tablets effective. Even our grandparents used Harris Roach Tablets. The principle of action and the composition haven’t changed since. You’ll find about 100 tablets in a box which have to be put in the places where there are most cockroaches. The tablets don’t exude any unpleasant odors or harmful spirits; they simply lie there and wait to be eaten by the roach. However, they definitely have to be hidden from pets and toddlers. They don’t attract cats and dogs, though, but kids can be drawn by them, and, in that case, the kid will be seriously harmed.

Harris Roach Tablets: photoAs a rule, people place the tablets into the fridge, on the furniture, windowsills, in the gaps, behind the trash bin and sink, in the bathroom and on other objects. The more tablets are used simultaneously, the more dead cockroaches the happy users will find. We were also unable to find any complaints about the effectiveness of the product. The only complaints would be the stories of parents who have to keep their children away from small white tablets which look so edible.

10 Gentrol Point Source IGR Insect Growth Regulator Discs~~ Half Box~~ ~~ Control German Roaches and other Cockroaches as well as Stored Product Pests....

Gentrol IGR Discs is a hybrid of a bait and pure poison. We have a sterilizer which affects cockroaches without contacting them. All you have to do is put the small white planks in the apartment, open them by pressing on a designated spot on the case, and wait. The chemical will spread over your place and sterilize the roaches. It also regulates the growth of born eggs and larvae. They will never grow up.

insect growth regulator discs: photo

The customers in the comments sections complain that no manual is provided, and thus they have to rely on their own sixth sense to operate it. Such an approach helps many people get rid of the cockroach, as the 4.2 out of 5 stars rating testifies. Both the official description and the reviews state that the discs are to be replaced every 90 days and that each of them covers an area of 75 sq. ft. Inside the discs, you can find hydroprene which limits the insects’ growth. 

As for the reviews, many of the customers recommend using Gentrol as a supplement to the traps and poisons. The latter will eliminate parent insects, and Gentrol will finish off the offspring.
