If you see 3-4 cockroaches crawling around in your kitchen at night, it is an indicator that you have hundreds and thousands of roaches hiding in cracks, cabinets, under kitchen sink and pipes, so you have to do something before they invade your home completely and make your life hell.

We talked alot about Cockroach baits, and foggers in our previous articles. Today we are going to review Best cockroach powder available in the market that actually works. We already did testing, research and investigation so you don’t have to spend hours on research and reading the reviews. 

Even embarrassing when you invite your friends at home for a party and they see creepy cockroaches flying and crawling all over the place. This can become very serious if you have a wedding function or something important. 

There are some home remedies that you can use to get rid of cockroaches. But these remedies sometimes do not work or require some time to tweak it make it perfectly right. 

But don’t worry, there are so many other ways to skin the cat!

Home Remedies can only work in small infestation, and it is a huge time suck and pain in the butt. For large cockroach population, I highly recommend to use commercial product.

Majority of roach products available in the market use boric acid as active ingredient. There is a misconception about boric acid that it kill roaches on contact. It won’t!

When you treat your house with boric acid, when cockroaches crawl over it. Boric acid particles stick to cockroach body and when they clean themselves by licking their body they ingest boric acid and eventually get killed.

This is the basic mechanism of product that use boric acid. Other products and active ingredient might work differently. See product label and check what active ingredients are used and then search google to see how that ingredients can work against cockroaches if you are curious.

The main difference about cockroach liquid based bait and powder is that liquid bait gets tried within couple of days while powder can work for months. This makes Cockroach powder a viable option for both household and commercial cockroach control.

However, powder based products are not good for “chain reaction” and killing the nest. Because it can’t be spread as gel based baits do. On top of that, gel based baits tend to attract more roaches as compared to powder based products.

We have listed best powder available in the market to treat cockroaches. Now lets deep dive into each product and discuss its active ingredients, application and safety precautions.

Each product works differently, we will go in details and check its active ingredients, online feedback given by other users and so many other things.

Here are some of the Best Cockroach Powder You Can Find Online:

1. Harris Boric Acid Roach Killer Powder

Harris is on the top of my list always when it comes to powder based roach control. It is a great company and has tons of experience creating household pest control products. I have seen so many pest control professionals who use Harris boric acid based powder for treating cockroach infestation. 

As per company claims Harris powder was used in the Whitehouse (Way back in 1924 when Calvin Coolidge was american president)  After successful roach elimination from white house, it was used on other important government buildings for example in senate, supreme court and other buildings. 

This is not just another china imported products. This product is made in the USA and are registered with the Environmental Protection Agency (EPA) .    

Now this gives a huge power and trust this brand and that is the reason thousands of users are buying this product day in day out. If you are brand oriented person, this is probably the best product in terms of effectiveness and price.

By the way, sometimes cockroach problem get priceless! Customers are willing to pay hundreds of dollars if someone can help them control the situation.

Harris use boric acid and some other food substance. Boric acid is used as active ingredient and the additional food substance is used to lure cockroaches which is very powerful.

These extra ingredients makes it different from using boric acid yourself. These companies spend millions of dollars on studying biology of target insect, their behaviour and how they react to different baits.

This product seems to be in the market for almost 100 years. Which makes its manufacturer stand out from the crowd.

Application

You don’t have to sprinkle powder over cockroaches. Apply powder in high infestation areas ( Crack and Crevice, crawl spaces, under kitchen cabinet and sink)

To increase chances of a cockroach crawling over the powder, create a barrier around cockroach infestation. Treat all entry points to your cabinets, under the sink. The more targeted area you treat, the higher cockroaches you kill in the process.

Do you have a garbage can in your kitchen? Treat it!

It wouldn’t be a bad idea to put some powder in garbage collection can outside your home. You will be surprised to see cockroaches in trash can outside your home.

You might be asking what should i bother with cockroaches outside my home ? They invaded your home from outside in the first place!

Cockroaches can only get inside if you allow them and create the environment they need. So it is always a good idea to take preemptive techniques to reduce risk of cockroach infestation. Putting powder in trash collector outside your house is just an addition to the same strategy. These roaches crawling around near garbage collector box would invade your home when they get a chance.

Funny enough, they don’t need your doors open to get into your home. Some species of cockroaches can swim under sewage pipes and they can enter your structure by just swimming in sewage pipes.

Periodic inspection would be required to make sure powder is kept dry to remain effective. Re-apply more powder if first round wasn’t effective.

How It Works?

Haris use boric as active ingredient and some food substance to lure cockroaches to get maximum damage. As discussed above, once cockroaches crawl over the powder, its particles stick cockroach body and when they lick themselves they inject the poison and get killed within 24-48 Hours.

You might be interested in reading about my other article about boric acid: How Boric Acid works against Cockroaches

Affected roach can bring back powder to their nest and kill more roaches in the process so there is a chain reaction and you get very good control in a couple of days.

But chain reaction of powder based products isn’t good as compared to gel base baits.

Different scientific studies proved the effectiveness of boric acid for cockroaches. But you have to add some sort of ingredient to lure cockroaches which Haris did it really well. This is the reason why this brand is in favorite product of even pest control professionals

2. Zap-A-Roach Boric Acid Roach Killer Powder

This is another boric acid product especially designed for cockroaches, ants and other bugs. It works exactly as Harris roach powder, but it is less popular brand. If you aren’t a brand oriented person, this might be a good option for you.

You get two 16 oz bottles one pound a piece. This is a lot of material you can use for almost one year. I bought it for myself last year and i had half of stuff left which I gave to my friends with a huge roach infestations.

This would be a nice gift for someone who has severe roach infestation. If you buy it yourself and works well for you, why not help your friends to get rid of these pesky little creatures.

I get a lot of emails about the smell of these products. You can easily read this on label or in product description before you buy it. Zap is odorless so it won’t smell bad. You can freely use it if you have guests coming in. It can do the same thing as other product but for relatively low price.

The best thing about Zap-A-Roach is that its substance is non-staining, so it is safe to use on a variety of surfaces including floor, baseboards cabinets etc.

One user has reported that she used it as a spray and worked really well. I don’t have evidence to support this but it’s worth a try. Mix the powder in water (put some sugar in the water) and spray as you normally do.

It wouldn’t work for flying insects. The product is especially designed for crawling bugs because the bag has to crawl over its substance to get killed

User Feedback

I checked different retail sites and customers seem to be satisfied with the product. (Excluding few bad reviews)

One user has reported that she got good success by just sprinkling it on baseboard, in cabinets & and in trash box (so many people ignore this) cockroaches like to live near trash boxes in both kitchen and outside your home.

If you have a garbage collection box outside your house, must apply some insecticide on top of it. A few roaches in trash can invade your home even if you get control inside. So it is necessary to get control both inside and outside

The product is advertised as both ant and roach killer but some user has reported it doesn’t work for ants.

Just want to make sure, always use a product that is designed to attack one type of insect. You might see dozens of over the counter product claim to be working for almost anything on the planet.Thats far from reality.

Each insect has different biology and different ingredients are required to treat that specific pets. Especially if you are dealing with pests like cockroaches, you really need to make sure you are buying product especially created with active ingredients that control cockroaches.

If you do meta analysis about 70% of people are satisfied with this product.

3. Bayer Tempo

Bayer is a Billion dollar Pharmaceutics company based on Germany.

Bayer tempo is another dust product for roaches. This product is mostly designed for commercial use. If you have roaches in your hotel, restaurants, hospital or food handling areas, you should use temp by bayer.

Tempo use cyfluthrin as active ingredient. It works both as stomach poison and on contact killing. It attacks the nervous system of insects and eventually get paralyzed and killed.

More Information about Cyfluthri from National Pesticide Information Center. Tempo can be used if you have cockroach resistance issue. You might be wondering which is this? 

Well some species of cockroaches can create resistance against specific type of insecticide and it won’t work no matter how much you treat the area with insecticide.

This isn’t a myth this is proved by scientists over and over again. A study published in journal of economic entomology by Donald G Cochran studied Monitoring for Insecticide Resistance in German cockroaches and they found resistance can be a serious issue in some species but can be treated with proper insecticide. 

I have so many complaints about Top line products and each time investigate the issue, there is resistance issue!

The easy way to deal with resistance is to simply change the product with different active ingredients. This is pretty normal practice by pest control professional. Some pests can create a very strong resistance against insecticide which is very hard to deal with sometimes. 

Each pound can treat utpo 1,000 sqft area. Which is huge! 

This product might be toxic for honey bees so ditch using it if you have honey bees in surrounding.

Boric Acid Won’t Effect Eggs

This a huge drawback of boric acid based products. It won’t destroy egg cases that is ready to reproduce. It does kill female roaches with egg case inside but it does not affect eggs that is ready to give birth.

For small to medium infestation it won’t make a difference but if you have a huge cockroach population in your area. Boric acid based products won’t work well because new roaches will increase population pretty quickly.

To be fair, getting rid of egg cases is not that easy. It takes a lot of time and energy to do that and even pest control companies won’t do that. They’d prefer treatment after every 3-4 months. And it works because even if you get rid of egg cases, you can still get cockroaches in your houses from other sources.

So getting 100% control isn’t worth it. There will always be some sort of infestation, few roaches won’t even affect you at all.

Don’t worry if you see few roaches even after you treat your house. Monitor the infestation and re apply bait or any other product before it gets severe. The mentality of a hundred percent control is going to get you stressed.

There is no such thing. Even professional pest control company won’t give you a guarantee that you won’t see a single cockroach after they treat your house. This isn’t realistic , they only can guarantee 80-90% control which is very good. And you should shoot for the same when you are doing it yourself.

How To Find Infested Area?

To save yourself sometime and applying products on useless areas here is what you need to identify cockroach infestation. 

Cockroaches tend to prefer dark, moist places to they use moisture as water source. Cockroach would likely live under kitchen cabinets, under the sink, Crack and crevice in cabinets and under the refrigerator. 

Look for obvious cockroach infestation signs, although you don’t need any sophisticated equipment to figure out roach infestation.

It is pretty simple and straightforward. You have to check areas where cockroaches like to hide to get a better sense where you should apply your product to get maximum possible control. 

To get a better idea, inspect your kitchen or bathrooms in night time. Because cockroaches are mostly active at night and you can see a huge population which would help you to diagnose infested area for treatment in the day timings.

Powder vs Gel Baits For Cockroaches

I am a big fan of cockroach gel bait. Overall gel gives you a better control but if you are looking a comparaitley natural product and you like powder based insecticide ( it might be your personal choice) than you should opt for powder based products. 

I wrote as much detail as possible about powder products. Do your due diligence before buying gel based or powder based products. It might depend on your personal taste and type of infestation. 

In general, Gel based baits are very popular amongst users. 

Do you have any personal experience with cockroach powder based products, please let me know in the comments, I’d like to start a conversation. A healthy debate always works and it helps the end user.
