And that’s not all. We will take a closer look at the factors you should consider when buying a roach killer and the various methods you should consider trying out. What has worked for someone else, might not necessarily work for you?

Read on for an in-depth analysis and comprehensive product reviews and we can guarantee that your roach problem will be no more.

How to choose the best roach killer under a budget

When you are facing a roach problem in your home, you want to try the fastest but most effective way possible to deal with them. A few hours of research will present a couple of methods and now it’s up to you to make your choice.

Just like when choosing other products, there are a few factors you should consider before making your purchase. We will take you through a few that you can consider, especially if you are on a budget and you cannot afford to splurge on expensive methods.

Frequency of use

You have to take into account just how many times you will be required to apply the treatment to completely eliminate the roaches from your home.

Even if you cannot afford to spend so much on a roach killer, look at the techniques that will be economical in the long term.

For instance, if you have a heavy infestation, you can opt for baits because in most cases, one pack will come with around 15 baits which you can spread around your house for more efficiency; and all the baits go for a really affordable price that won’t break your bank.

Some methods like killer spray always lose their ineffectiveness when you clean the sprayed surfaces or even step on them. When you are on a budget, its best to stay away from such roach killers because you will be required to keep buying more cans after having exhausted the current one, which means spending more money in the long term.

When you can’t afford to splurge on a roach killer, we recommend that you apply your preferred technique very thoroughly, so that it can get rid of most, if not all, roaches in the specified amount of time. This will save you money you would have otherwise spent on more purchases.


Safety should always be your first priority when purchasing roach killers. Will the technique you have in mind affect your children or your pets? Will this killer put your family at risk of contamination?

Look at the methods that fit your budget and then look at the safety precautions you will have to undertake during application. We advise that you disregard any technique that you feel like will be detrimental to your safety at home, in any way. Boric acid and silica aerogel are among the best affordable roach killers out there with low toxic levels.

The next step would be to always wash your hands thoroughly after application of a roach killer. If you are dealing with roaches in the kitchen, it’s best to store all your foods in ziplock bags to avoid contaminating them.

If you have pets and small kids who keep running around the house, then methods like killer sprays may not work best for you because they will step on the sprays which deem them ineffective, not be forgetting the part where you have to keep reapplying more times and purchasing more cans which are expensive in the long run.

Moreover, it’s vital that you ask about the toxicity levels of a roach killer. Go for the ones with lower levels, of course also having considered the price. Always check the environmental hazards listed on the packaging, and eliminate any killer with more hazards.

Lastly, you should consider the residual life of the killer; the longer it can stay, the more economical it is. Do not forget to wash off the surfaces with the pesticides after they have become ineffective. This is to avoid your kids or pets later coming in contact with the chemicals.

This is not a major safety issue but you should keep in mind that there are some killers that end up staining your home surfaces and fabrics. You should get information on how best to deal with such occurrences without affecting other areas in the house.


We have all been there, wanting the best products but we just cannot afford it. Most consumers always consider the cost factor before making any purchase, and roach killer products have not been left behind.

There are very many ways to eliminate roaches from your homes and some are definitely more costly than others. With cockroaches, you want the best product that can eliminate all in a short period of time. Mostly, these products are more expensive than you thought.

So how can you get the best products at a good price? Depending on the levels of infestation, first, you have to consider whether you need larger quantities or smaller doses. There are some roach products that come in very small quantities but are so costly.

You can focus on getting the products that give you a good value for your money. Let’s say those that you can apply for longer periods, over six months, or those which come in pairs or more, but for one great price.

Even if you are on a budget, buying the cheapest products may end up being expensive in the long run if they are ineffective and now you have to go back to the store and purchase the more costly ones. It’s very important that you always try to balance out the costs with the killers’ success rates before making any purchase.


It’s very frustrating purchasing a product that just doesn’t seem to work for you. If you have a cockroach problem, you want them out of your home as fast as possible which makes you desire to purchase only the most effective killers.

Most pesticides that are deemed to be the most effective are very costly. This should not worry you, especially if you are on a budget. Keep in mind that they have been tested mostly in labs, which is a controlled environment and quite different from the real situation that is your home.

Before making any purchase, you can always go online and read other user reviews regarding these products. That’s exactly how you know just how effective they are because they have been tested in real life situations. The best part? The most deemed effective roach killers are even not that expensive and you will be relieved to realize that you can afford them after all.

Species specificity

When you are on a budget, you just cannot purchase the wrong products because if they don’t work, getting alternative treatments might end up breaking your bank.

There are different cockroach species out there, which only means some have higher endurance levels towards some roach killers more than others.

The first step is finding out the specific species in your home so that when considering which treatment to use, you can go for the one designed to eliminate the species. If there is no way of finding this out, you can try spot tests of a couple of low-cost treatments just to see which chemicals work with the roaches in your home.

Endurance levels

We have all been in situations where you think the roach killer you just purchased is working only to later realize that the roaches are in fact multiplying in numbers. How heartbreaking!

What happens is that at first, the pesticide may be working and actually eliminating these cockroaches. However, with time, they build up a resistance against the chemicals which seems the killer ineffective and thus they keep multiplying as usual.

You have no way of knowing whether the pesticide you buy can limit the growth of the roaches in your home until you actually try it out.  This means that you can’t just afford to spend so much money on one treatment if you haven’t tried it out first. Start small, with less costly products and see what works for you then you can stick to using the particular killer.

Ease of use

Despite focusing so much on the price, you should also consider the ease of application of the roach killer. If it will give you a hard time even if it’s within your budget, then do not make the purchase.

Killer sprays, for instance, are equipped with fan sprays and nozzles that help you reach both inaccessible and open roach infested areas easily.

Wrapping up

We end up focusing so much on the prices of various products and often overlook the most important factors. For roach killers, before making any purchase, it’s vital that you ask yourself just how effective the killer is, how long you can use it and also its toxicity levels.

Do not shy away from spending just a little more over your budget for a good product. You know how frustrating living in a roach infested is, and therefore when planning to eliminate them, you cannot afford to go wrong.

It’s good to have a budget for your purchase, but this should not limit you from exploring other more effective killers outside your initial budget. What matters is just how successful they will be in making your home cockroach free once again.

Types of roach killers you will find on the market

There are different types of roach killers in the market for your home, but each treatment method varies in terms of application and how best it works. Additionally, not all killers are designed to kill all roach species, so you might have to find out what type of roaches you have in your home. Alternatively, you can decide to use a method that can eliminate all roaches, regardless of its species.


Poison gel baits

If you are looking for a safe roach killer that you can use in sensitive areas, even in your kitchen without worrying about contamination and odors, baits are your answer.  The active ingredient, Indoxacarb, works by blocking sodium channels in a roaches’ nervous system. This leads to severe dehydration which causes death.

Baits don’t eliminate individual roaches. Far from it. They kill entire colonies in one go; when a cockroach ingests the poison, it goes back to its nest, and after excreting the poison, ends ups spreading the bait to the rest of the roaches in there who die as well.

You should keep in mind that baits may take longer to work, as compared to other roach killers, but that doesn’t mean that they are not as effective. Once the poison kills the first batch of roaches, their eggs hatch which brings up another generation. You have to keep putting out the baits to do away with all of them.

They work best when placed along corners or edges, basically any path that roaches travel on in your home. Other areas of interest might be under your sinks and along baseboards.

Additionally, you should never use other killers such a sprays alongside the baits. This ultimately renders them ineffective because roaches tend to ignore them.


Sticky glue traps

Glue traps are also very safe to use as roach killers since they come in handy in all situations. The best part about using these is that you can know which areas are more infested than the others depending on how many dead roaches you find stuck on the traps.

The major flaw is that they only attract a specific breed of cockroaches; young roaches, nesting females and male cockroaches ready to mate. So if you don’t know exactly what type of roaches have infested in your home, it’s better to adopt other treatment techniques.

Additionally, they only eliminate the cockroaches that are trapped, leaving the source unaffected. This lowers their success rate and you might consider using an alternative method alongside the glue traps for more effectiveness.


Killer sprays

This is one of the fastest actings and long-term roach treatment methods we have in the market. Reason being, with a spray, you get to the cockroach the minute you see it. You don’t have to put out a mixture and wait for the roaches to ingest; you use the spray directly on the pest, killing it instantly.

Synthetic pyrethroids, which is the most active ingredient in most sprays acts by interfering with the roaches nerve systems, which ultimately leads to paralysis and later, death.

The downside to this method is that once you step over a sprayed area or clean, the spray is deemed ineffective. Most sprays are designed to last for a couple of days on a surface such that other roaches coming into contact with it also die.

Moreover, chances are when you spray on a certain surface, let’s say a crevice, you might drive the roaches further in and end up making your problem a little worse. Therefore it’s important that you target their nests, alongside killing them on sight. This is a more effective plan altogether.

The sprays will usually come with either plunger-type of sprayers or hand compression air sprayers that allow you to apply the pesticides more effectively. They are designed to have pin stream nozzles which you can use when targeting the roaches in crevices and other areas that are hard to reach. Alternatively, for the easily accessible areas, the sprays have a fan spray for that. The best part is that you can always use a paint brush if you cannot get the other listed equipment.

During application, focus on moistening the area but not to the point where the contents are dripping or running off. This can end up contaminating other areas in the house. With these sprays, you can start off with a heavy application and ease towards periodic subsequent treatments to make sure that the remaining roaches are completely eliminated.

With a successful treatment, you will be able to get rid of all the roaches, without worrying that they will just move to another area in your home. Most companies are manufacturing sprays with very low volatility, in a bid to make them less harmful to your family and pets.

Do not use the sprays on surfaces where you handle food to avoid contamination. And if you have to, ensure that all your food is stored safely in zipping lock bags and kept out of sight.


Boric acid

This is a chemical substance that has low toxic levels to humans but is quite deadly to cockroaches, making it among the most effective roach killers there is.

Its major disadvantage is misapplication; where the powder is easily misplaced by air currents in the house, especially if you use ceiling fans. When it ends up on food or pets, it becomes quite hazardous and can cause bodily harm.

It’s one of the slowest methods we have in the market, but despite this, it will manage to eliminate all the roaches in your home. You will also love the fact that boric acid is very affordable as compared to all other methods.

Wrapping up

As you have seen, there are different types of roach killers out there. What you purchase for your home will depend on the roach species, how effective the killer is and how much it costs.

We have also given you the pros and cons of each method. Keep in mind that what works for someone else may not necessarily work for you. Therefore, do your research and make an informed decision. If one method doesn’t work out, do not give up, just get an alternative treatment and see if it manages to eliminate the roaches. If it doesn’t, move on to the next method until you can get what finally works for you.

Top 5 Roach Killer on the Market

Below we listed some of the best roach products you can find on the market right now. We checked their features and reviewed their pros and cons so you can make an informed decision whenever you are out looking for a good roach killer for your home.

Here is a table that you can use to compare the six roach killers easily when you want to make a quick buying decision.


Advion Syngenta Cockroach Gel Bait review

Advion Syngenta is one of those affordable roach killers that is manufactured to eliminate all cockroach species. The MetaActiveTM is a non-repellent compound found in this gel, an active ingredient that even the toughest of roaches cannot get away from.

The application is pretty simple; you only need to dab a few drops on crevices and cracks found in your home; targeting both indoors and outdoors spaces. You can also target other hidden areas like under the sinks and refrigerator, by the stove, behind doors and even behind your dishwasher and microwave.

The most effective way of application is using polka dot pattern on the surfaces, which should come after you have thoroughly vacuumed your house. However, we recommend that you store your foods well during this time, probably in zip lock bags, such that the gel does not come in close contact whether with your foods or utensils in the kitchen. Keep in mind that roaches roam around, even after stepping on the gel, and might spread this all over your house, making you susceptible to diseases.

You may not see results the moment you use the gel; but after a few days, you will start finding dead roaches all over the floor, especially if you had a bad infestation. Chances are, some might survive, but this should not worry you because they get weak and also die after some time.

What’s more? The gel goes for approx. $23.42, which not only gets you 4 tubes but also gives you a good value for your money. You get to save money that you would have otherwise used on much more expensive treatments.

Pet Soldier Electronic Plug Ultrasonic Pest Control Repeller review

Purchasing this Pet Soldier Pest Control Repeller will get you a set of 4 white electronic plugs at approx. $39.99. This plug uses high-density ultrasonic frequency technology that produces inaudible sound waves and eliminates all kinds of pests from your home, including all cockroach species alongside rats, bugs, mice, and spiders.

The application is super straightforward; you just need to plug in the Repeller and you are good to go. Each plug will cover about 1250 square feet of space. If you are worried about inhumane ways of getting rid of roaches, the Pet Soldier is certainly cruelty-free.

It works by repelling the roaches away from your home and making sure they don’t keep coming back. The sound waves attract the roaches out of their hiding places and since they cannot survive under such conditions, they end up leaving your home.

It’s an organic and safe way to get rid of roaches, without emitting any hazardous fumes, odors, and chemicals in your home. You can have the plug on for 24 hours every day and you will hardly notice that’s it even there. The sound waves produced are so inaudible that even other pets in your house like cats and dogs will not be bothered.

The best part is that for areas such as the attic and basement where you can’t access every day, you can just leave the plugs and let them repel the pests there and all you have to do is check every other couple of days to ensure its working.

However, some users have complained that they did not see any results within the first month of their purchase. You might want to leave the plugs out for longer to see if they finally work, or you can consider looking for an alternative method altogether.


Combat 12 Month Roach Killing Bait review

Most roach killers work by eliminating the pests away from their source, but not the Combat 12 Month killing bait, which is designed to only target the source of the infestation, making it among the most effective methods we have out there.

Just like the Huvai, you will need to use bait for this method to work. You will need to place your bait in specific areas like under your sinks, behind toilets and appliances and in large cracks and crevices.

Combat works under the domino effect assumption that once the roach is attracted by the bait, it will take it back to its nest, which will end up affecting all other roaches present, and ultimately also destroys the nest. Any roaches that feed on the dead ones are poisoned by the bait and they die too.

You can choose what to use as bait, as long as it’s a sweet food that will definitely attract roaches, like a piece of chocolate, cookie or some sugar.

Combat is mostly used to attract small roaches, using fipronil, as its active ingredient. The best part? You can start seeing results very fast, in hours and the bait, which will cost you approx. $10.97, will keep giving you protection against roaches for up to twelve months.

You are supposed to use all the 18 baits found in the packaging, and once the twelve months are up, you are required to safely dispose of all of them. Additionally, we advise that you don’t use sprays around the baits because they will ultimately reduce their strength and effectiveness.

Keep the baits away from your pets and children, and always wash your hands thoroughly after handling them.

One of the major downfalls of this product is that after laying the baits, you just hope the roaches find their way to them. Some users pointed out that roaches did not get to the bait in some areas such as the bathroom, which then reduced their effectiveness to completely eliminate the pests.

A few users have complained that the bait does not work, even after months of use, while others have been completely satisfied with the effectiveness. Some also brought up the fact that the bait clip does not fit on larger appliances such as a ceiling fans. Therefore, you only need to try out and find out for yourself.


Raid Ant & Roach Killer Insecticide Spray review

Raid Ant Roach Killer is a spray that kills cockroaches on contact, with a 17.5 oz. bottle going for approx. $8.20.

You don’t have to worry about sprays with fragrances anymore because Rad Ant is not only fragrance-free and odorless, but it lasts for up to 4 weeks on the application. It works by using a water base technology that will leave little oil residue on your surface, and eliminate all the roaches you come across.

Some roaches are immune to other forms of pest control, but Cylathrin, which is the active ingredient in Raid Ant, will not spare even one upon contact. This spray lasts for up to 30 weeks even when dealing with the heaviest of infestations.

Upon application, you will realizes the roaches will die in about 15 seconds. Sprays are a bit convenient because you can just keep it at an arm’s reach and use it whenever you spot a roach. It’s not like applying a pesticide and waiting until roaches make their way to it. With a spray, you can get to all the roaches in your sight very easily.

The major downsides to this using the spray is that it might leave your floor a bit slippery and therefore, you will need to clean up after every application, to prevent accidents. Additionally, it only kills roaches on contact which means, you are not able to get rid of most of the ones that have hidden nests.

Some users have also complained that once you have sprayed on a surface, the insecticide will not be as effective after a couple of days, despite the description that it can last for up to 4 weeks.

You might also want to be very careful during application, not to get the spray on your pets because it causes irritation and itching that doesn’t go away for hours.  You should also wash your hands thoroughly after handling the spray to avoid contaminating food and other surfaces in your home.

There is no lingering smell after using the spray, but you will notice a faint chemical odor that will go away after a few minutes. Other than that, most users were satisfied with its effectiveness.


Harris Boric Acid Roach Powder with Lure review

Harris Boric Acid is an effective Roach Powder that kills roaches within 72 hours of coming in contact with it. It’s also very long lasting and continues to kill roaches weeks after your initial application, but as long as no one steps on the powder.

It’s manufactured with the irresistible lure, a chemical ingredient that attracts roaches from their nests to the powder. They die soon after ingesting it.

The application is pretty much straight forward since it comes with a puffer designed with an extended straw that you will use to get to those hidden areas, such as under sinks and behind appliances. It’s very effective, especially where liquid insecticides have failed.

Another upside to having the straw is that the powder will not come into contact with your hands. You can mix it up with a little sugar if you want to attract the roaches instantly.

We recommend that you keep the powder away from human reach and pets because once ingested, it can cause harm to the body. You will also notice that sometimes with a heavy infestation, the powder takes a little longer to eliminate them all. Do not give up just yet, just give it a few more days and you will start seeing dead roaches all over.

What’s more? It will cost you approx. $ 8.99 for a 16 oz. can, which is a good value for your money. Most users seem impressed with its effectiveness to get rid of roaches just within a few days. This is also driven by the fact that you can get a powder to even the tiniest of crevices in your home that other treatments might not be able to get into. The extended straw sure does come in handy at this point.


There you have it! An in-depth analysis about all you need to know about roach killers, different types we have in the market, the factors you should consider before purchasing one and most of all, the best six products that are out there.

We have also given you the pros and con of each product and treatment method so that it can help you know what can work for you and what roach killers to stay away from.

Having a cockroach infestation in your home can be very unsettling and frustrating and it’s up to you as the homeowner to know the best way to eliminate them. Keeping safety in mind at all times, because killers with high toxicity levels are detrimental to the health of your family, including your pets.

Not sure which method to go for exactly? You can try out a few just to see what is most effective with the roach species in your home. Purchasing different products especially when you are on a budget can seem like a difficult task but it’s always worth it in the end when you can walk around your house and not see roaches scurrying around.
