This is the quickest way to kill a cockroach. There is nothing faster than spraying directly on the cockroach which will kill it instantly.
The uncontrollable urge to just smash a cockroach flat instantly at just the sight of it is uncontrollable. An urge as such is understandable and to just put an end to their infestation by smacking roaches is impractical much. A much easier way of killing roaches is by using sprays.
Roach sprays are used to target the areas where the cockroaches gather like the cracks, window frames, skirting boards and places usually not reachable with bare hands. Roach spray is an aerosol spray that comes in cans or bottles. On spraying, the effect starts within seconds and kills the cockroach that is sprayed on in no more than 5 minutes. Sprays are most widely used repellents of all for a fast solution.
The basic pesticide used in a roach spray is synthetic pyrethroids. This affects the central nervous system of the cockroach and kills it as quickly as possible.
How to use a roach spray
- First, cover your nose with a face mask or tie a handkerchief around your face before you use the roach spray.
- Then, locate the target area and place the nozzle of the can pointing at the area where you want to spray.
- Once the nozzle is pointed towards the affected area of your house, spray it.
- A few pointers to keep in mind while using a roach spray are
- It is important to keep children and pets away when using roach sprays as they emit harmful chemicals.
- These sprays are highly inflammable.

Cockroach Gel Bait
To keep roaches at bay, humans come up with various seemingly effective solutions. Not all of them work a cent percent. We never stop trying though. In this war against roaches, Cockroach Gel Bait is one such hopeful solution.
The effectiveness of this is however not up-to-the-mark. To lure cockroaches into falling for this bait is tricky. The catch here is to entice a cockroach into eating the gel bait. In most cases, cockroaches exhibit a certain kind of aversion towards it. Therefore, infestation continues if they do not consume it.
The bait works very rarely as most of the times, it’s difficult to locate them as they can be scattered all over a place.
How to use gel bait
To use this bait, one needs to follow the following steps:
- Firstly, you must locate the spots you want to target.
- Usually, places with feces of any kind, or leftover food near trash cans in your kitchen or small cracks and crevices in walls and floors are where these critters are found.
- Then, once the spots are located, place small dots of the gel bait.
- The gel bait dries up over time losing its effect. Therefore, keep reapplying it.
If you are looking for a way to disinfect a larger area like a warehouse or an office or an entire apartment, a fogger is your solution. It is an expensive way but an effective one to get rid of a cockroach infestation quickly.
Roach Fogger works by transforming the poison into dry fog particles less than 15 microns in size. The fog which consists of the roach killer components can percolate into any openings or crevices where no other product can reach.
It takes up to 6 hours for the infestation to be brought to an end from the time of its use. Dry fogging is usually a professional way to deal with pest problems. If you want to do it yourself, you can buy a thermal fogger machine yourself. The working mechanism is the same.
On using a fogger, the roach poison particles rise up in the air and then gradually settle. While settling, they fall onto small cracks and openings and even on ceilings and walls killing every adult, larva or ovipositor. The effect lasts from 40 to 60 days of its use. It provides the best result, the closest to professional extermination.
How to use the fogger
- It is a toxic pesticide that can cause harm to pets and children and to the one using the fogger. Therefore, before using it, make sure to vacate the place for at least 10 hours and cover your nose with an effective face mask, wear glasses for your eyes and gloves for your hands.
- Cover all the food and drinks at home.
- Make sure the poison does not come in contact with the skin.
- Then, the low power equipment is turned on and sprayed all over the place.
- Once the necessary precaution is taken, use a generator of high-temperature dry fog. Ordinary sprayers are not equipped to create dry fog.
- Use a high-quality poison. And make sure to not use the same poison every time as cockroaches can adapt and develop tolerance too often.
You must be thinking, predators!, What animals do like eating cockroaches?
Well, the list of predators is never-ending. Turns out, a cockroach is a pretty liked delicacy for most animals including mammals, reptiles, amphibians. Animals like hedgehogs are very fond of eating cockroaches. Reptiles like lizards are one of the greatest predators of cockroaches. Be it house lizard or geckos.

The Argentine black sugar ants are also predators of cockroaches. Other than these, mites, centipedes and roundworms too feed on cockroaches.
If you want a fairly inexpensive alternative to getting rid of cockroaches and a lesser harmful way of pest control, boric acid is your answer.
Boric Acid is highly poisonous for cockroaches and is the best bait that you can use at home. However, the only drawback of it is, on getting the faintest whiff of Boric Acid, the cockroaches instead of eating it, go as far away from possible from it. That does not kill them. In order to die, they must eat the powder.
How to use Boric Acid
In order to lure them into eating it, first, you will need to eliminate the smell of Boric acid. To achieve that, you need to mix boric acid with raw egg yolk.
- Take 50 mg of Boric acid and mix it well with 1 raw egg yolk.
- After blending it well, it will form into a gruel. Roll the gruel into small balls of 1 cm in diameter and leave these balls to dry.
- Once dried, spread these balls in the targeted territories and let the cockroaches snack on them.
Or you can also leave the powder as it is by sprinkling them all over the desired location like sinks, toilet bowls, places around any water source and around trash bins.
Once the infestation seems to have uprooted, you can wash off the boric acid with a wet rag.
Another natural remedy to kill cockroaches is by leaving a baking soda and sugar mix for cockroaches to feed on. The combination plays ‘trap to kill’ as sugar attracts the cockroaches and the baking soda kills.
Cockroaches do not have any gastrointestinal mechanism to release gas. On eating baking soda and then drinking water after it creates gas in the roaches and therefore causing the reason for death.
How to use baking soda
- You must mix equal parts of sugar to equal parts of soda and leave it on unusable plates or lids of old containers in places which are not easily reachable like behind wardrobes, under sinks, under refrigerators.
- If possible mix yeast with the mixture and let the roaches get lured to eat it.
- Once they eat the mixture, they go near water sources and die as a result of the explosion of its stomach.
Bleach is an inexpensive repellent. It sure is doubtful to put a complete end to your roach problem, however, you can use it to keep them at bay. Bleach gives off a strong smell that the roaches hate.
Therefore, instead of enticing them to eat, the smell of bleach sends them away. Hence, leaving bleach as it does not kill cockroaches.
How to use bleach
- Use an old bottle and attach a small spraying nozzle.
- Make a solution of bleach and water and pour it inside the bottle.
- Shake it well before spraying them on the cockroaches at sight. The cockroaches will be soaked in the mist and die eventually.
However, bleach is a corrosive product. It is therefore not really advisable to use bleach to treat your cockroach problem at home.

- Firstly, locate the most known places of gathering. Usually, areas surrounding water sources, or places in your house with easy availability of food.
- Once you have located, dust the area with borax.
- The cockroaches walk over the dusted area and the borax stick to their feet and when they clean their feet off, the borax is eaten by them which causes their death later.
- Sometimes, on feasting upon the dead cockroaches, the feeding cockroaches too die if there remain traces of borax.
