Roach spray is an excellent alternative to baits and traps. It is easy to use, is very quick, and is often very affordable. However, the market is flooded with hundreds of roach killing sprays, and everyone claims that they have got the perfect product.
Some manufacturers even claim that they have got environmentally friendly roach killing sprays. At the same time, other says that their cockroach sprays can even destroy eggs.
I have been using roach spray for quite a long and have been assessing them on various fonts, including effectiveness, availability, cost-effectiveness, residual effect, safety profile, and eco-friendliness.
Following is the list of the best roach sprays that I recommend,
- Bengal Roach Killer (Highly Lethal and Strong with Excellent Residual Effect)
- Raid Ant & Roach Killer (Effective yet safe Around Pets and Children due to Organic Nature)
- Dr. Killigan’s Six Feet Killer Spray (Effective and can be sprayed on day to day use items like bedsheets, Pillows)
- Ortho Home Defense Insect Killer for Crevices (Economical and can reach inside Cracks and Crevices)
- Hot Shot Roach, Spider, and Ant Killer (Kill roaches very effectively and can also kill other home pests including bedbugs, ants, and spiders)
It is essential to know that I have thoroughly tested these cockroach killing sprays and have found them very effective.
During the whole testing time, the one thing that I noticed which very much dictated the outcome was how you use the product. If you are using the product wrong all the time, then it’s very sure that you will get poor results.
For Example, Bengal Roach spray is a dry spay that contains bait. Therefore, it does not instantaneously kill roaches. Instead, once you spray it, you will have to wait for the next 2 to 3 days to get results. However, if you use Bengal roach spray and wash the area within the next day, you waste the product (It will fail to kill any roach).
List of Best Roach Sprays
The best bug spray for roaches is not essentially the one that instantaneously kills roaches. Instead, the best roach sprays are the ones that help you completely exterminate roaches, and you declare your house to be roach free.
Here are my recommended and time tested best roach sprays,
1. Bengal Roach Killer Spray
Bengal roach spray is my personal favorite and is the best in the market. The excellent thing about Bengal roach killer spray is its patented chemical “Nylar,.”
Nyler stays on the surface for long and keeps roaches in check for you for the next 4 to 6 months. That is why I believe that it is the best roach spray for home.
Bengal roach spray contains permethrin as its active ingredient, which is highly toxic to roaches, bugs, spiders, and ants.
The downsides of Bengal roach killing spray are its ethereal smells and safety concerns around pets. However, that can be avoided easily with proper room ventilation after use.

2. Raid Ant & Roach Killer Spray
Raid ant and roach spray contains Lemongrass oil, imiprothrin, and cypermethrin as active ingredients. This makes the product environmentally friendly and very safe around children and pets.
The Raid ant and roach killer is the best spray for apartment because unlike other roach sprays it lacks the pungent smell and we know the truth that apartments usually do have not up to the par ventilation.
The cons of Raid ant and roach killer spray is that for best results you must apply the spray directly to cockroaches or their nests. Moreover, it is also expensive compared to other products.
3. Dr. Killigan’s Six Feet Killer Spray
Dr. Killigan’s roach spray is also one of the best roach killer spray because of its unique combination of Castor, Soyabean, and Clove oil.
This product is non-aerosol, meaning you need to keep pushing the handle to apply the insecticide. Dr. Killigan’s spray is capable of killing all insects, including bugs, roaches, spiders, and ants.
The good thing about this product is that you can directly spray it on the beddings and sheets, which will help you repel roaches. The company also claims it to be non-toxic and devoid of pyrethroid chemicals.
The one drawback of this product is its range. It doesn’t fumigate and hence must be applied directly to roaches.
4. Ortho Home Defense Insect Killer Spray for Crevices
The best thing about this product is its ability to reach inside crevices and cracks because it comes with an extension nozzle that can be attached to the mouth of a spray can. Therefore it can kill cockroaches deep inside the walls pretty effectively.
One more benefit of using ortho home defense spray is its ability to destroy cockroach eggs. However, my personal experience with this has not been so good (maybe I used the product incorrectly?)
Last but not least, you might be wondering why I placed Ortho home defense roach killer spray fourth on the list. The reason is the product quality issues. Some users on Amazon said that their spray Can come leaked or was defaulted.
5. Hot Shot Roach, Spider, and Ant Killer Spray
Hot Shot is the best spray to kill roaches both indoors and outdoors. It doesn’t smell bad or pungent and has a refreshing lemon smell. Moreover, it will keep roaches in check for you for up to 3 months because of the residual effect.
Hot Shot roach spray kills spiders, ants, flies, and other bugs instantaneously and does not allow them to crawl around on the floor, scaring everyone around.
One downside of Hot Shot Roach Spary is its extreme toxicity, making it quite difficult to use around children, pets, and inside the kitchen.
Best professional Roach Spray
Do you know how & why professional roach exterminators successfully exterminate roaches? The answer is simple: they do not only use roach sprays to kill roaches. Instead, they use a combination of roach killing products such as Roach Baits, Traps, Insect Growth Regulators, and professional roach sprays.
Professional exterminators often make their composition of roach spray by diluting a strong chemical insecticide. The enviromental Protection Agency highly regulates these strong insecticide chemicals, and only licensed agencies are allowed to use them.
That is why you often see professional roach exterminators using off-label containers to spray the insecticide spray.
However, if you are a DIY enthusiast and looking for a professional roach spray, I highly recommend Ortho Home Defense Insects Killer.
Ortho home defense insect killer is a professional roach spray of 1.1-gallon liquid that has got excellent reviews.
The good thing about this product is that it kills roaches and is very effective against several insects, including ants, aphids, armyworms, beetles, black widow spiders, brown recluse spiders, and caterpillars.
Ortho Home Defense is the best professional spray because,
- It comes with a prepacked electric spray, making it easy to use.
- Has excellent residual effect, (once the roaches are exterminated, they won’t reappear for long).
- The liquid doesn’t stain walls and cloths
- It is odor-free.
- Safe to use around pets and children.
- No allergy to the liquid is reported,
All these factors make it the best professional roach spray.
To use it, apply a 4-inch barrier around baseboards, cabinets, windows, and other infested surfaces.
Best spray for german roaches
The German cockroach is the most common small roach that infests indoor spaces. This notorious and filthy roach measures half an inch in size and has dark strips on the back of the head.
The German cockroach infests houses, catering kitchens, high-rise buildings, apartments, damp basements, and untidy restaurants all across the US. It is also a notoriously fast breeder and gives rise to german roaches nymphs within 30 days.
Keeping all the factors in mind, the best spray for german roaches will be the one that nips the evil in the bud.
Here are two best Spray for German Roaches,
- Bengal Roach Spary is a dry bait spray, is slow in action but has lasting effect that predominantly destroys the whole German roach colony.
