How to Get Rid of Cockroaches?

Last Updated: 05.02.23


Getting rid of cockroaches is an arduous process, but it can be done right if you have purchased the best cockroach killer. Today, we have prepared a step by step guide that can help you kill the pests that have invaded your house. Additionally, we have also included a description that can help you identify the species of roaches that you are dealing with.


What are the causes of a roach infestation?

If you are dealing with a roach infestation, you are probably curious to find out what caused this to happen. Well, according to the specialists, there are a couple of factors that you should be aware of. 

First thing first, roaches are attracted to unsanitary conditions. This does not mean that an infestation only occurs in homes that are not well maintained. If one of your neighbors owns a home that is filled with cracks and rubbish, chances are that some of the cockroaches will soon visit your house.

On top of that, roaches usually infest homes where they have easy access to water and food. To avoid any unwanted visitors, be sure to do the dishes every night and make sure that all the food in your kitchen is properly stored.

One thing that many people do not know is that they can bring cockroaches inside their home without them wanting to. One can do so by purchasing second-hand furniture, or clothes. 



How to get rid of these pests?

Before you start your fight against roaches you have to understand that it is easier to exterminate roaches in a private house, rather than in an apartment building. This the case because, in apartment complexes, the insects tend to migrate from one apartment to another. 

If you intend to effectively get rid of the roaches that are currently in your home, it is recommended that you use chemicals as well as mechanical methods simultaneously. If you are not efficient or if you simply do not want to deal with these pests directly, you should hire professional help.


Identify the type of cockroaches you are dealing with

There are over 4,000 species of roaches worldwide. However, in the USA, people are often confronted with only two species: the German cockroaches and the American one. The German cockroaches have light-brown bodies as well as dark stripes that run parallel along their bodies. What is more, these roaches also have wings, but they rarely chose to fly.

German roaches are small in size and they measure around half an inch in length. They are known to prefer moist and warm areas such as bathrooms and kitchens. This species is the most common of the two. So, chances are that this is the type of cockroach that has invaded your beloved home.

American roaches are significantly longer as they measure around 1 ½ – 2 inches. They have a reddish-brown color and a thorax colored in faded yellow. This species likes dark areas and is most likely to be found in crawl spaces, basements and in and around drains.


Eliminate access to food

To start, you should make sure that the pests have no access to a source of food. Therefore, you should sweep the floors and place all food in airtight containers. You should not leave any type of food on the counter overnight as it is regarded as a feast by these insects. Moreover, the specialists argue that you should also do the dishes before you go to bed. 

To make sure that you have not missed anything, it is best that you perform this task methodically. For instance, you should check behind cabinets for debris and you should make sure that there are no crumbs in the toast maker. 

Your garbage should be placed in a bin that has a tight-fitting lid so that the pests cannot get inside it. Plus, it is strongly recommended that you take the trash out as often as possible.



Destroy their hiding places

The next thing that you should do is to eliminate the hiding places where the roaches hide. Because roaches like dark and humid places, it is vital that you seal any cracks in your home by using a caulk gun.

Also, make sure that you close all holes around the pipes and check so that all your door frames and windows are tight and inaccessible. You can also use tape to seal any crevices in the appliances that you are using in the kitchen. Exterminators argue that small appliances such as toasters or computers are often used as harborage by roaches.


Use baits

Once you are done cleaning and fixing up any entry points, it is time to start the elimination process. For the best results, you should use a powerful insecticide, baits and an insect growth regulator.

Baits are essential to the process of dealing with a roach infestation because these insects like to communicate with each other. Therefore, one cockroach that eats from a bait, might interact with other 40 roaches and, consequently, poison them as well.

Because of this, you must invest in high-quality, effective baits. You should place the baits behind the kitchen cabinets and countertops, under the stove, beneath and near the sink, around pipes, behind bathroom fixtures and in and near cracks, crevices, and shelves.

The baits have to be reapplied every 2 to 3 weeks. However, if you notice that a bait has disappeared, it is time to place a lay one in its place.


Use growth regulators

After all the adult roaches have been killed, it is time you use a growth regulator so that their offspring does not contaminate your home. A new infestation is possible and, in many cases probable, as roaches often hide egg capsules around the house.

To destroy the remaining eggs, you have to use an IGR product that contains a pheromone that effectively disrupts the lifecycle of the insects that are in the egg or/and larvae stage. You can find IRGs available in numerous forms, including sprays, aerosols, and liquids.



Use an insecticide

Finally, you should go ahead and use a powerful insecticide. You have to apply it in any cracks and crevices, under appliances, along baseboards and around the doors and windows. You can also spray it on the pipes and in the area where the cables enter the house.

Under no circumstances should you use the insecticide in the same area in which the bait was placed, as this will contaminate it and make the pests avoid it.

The insecticide that you have purchased should be reapplied depending on the instructions provided by the seller. So, be sure to read all the information made available so that you can avoid any accidents.

Chemical solutions have been used for a long time in the war against cockroaches. These products are effective, powerful and convenient, which is why many like to employ them. However, there are a handful of disadvantages that you should know about.

To start, because chemicals have been used for years to control roaches, the pests can easily build up a tolerance to some of them. When this happens, the solutions lose their effectiveness.  

Plus, many insects like to hide and wait for the chemical solution used by the homeowner becomes inefficient. Besides, roach chemicals have a strong odor and they pose a problem for those who suffer from allergies. 

Once you use the solution, you have to vacate the house/room and leave the solution to do its work. This can prove impractical for many.

At this stage, you can also install an insect catching device. Some also recommend that you use other products such as glue traps.  


Professional help

If you do not want to waste your time and money getting rid of the cockroaches that have invaded your home yourself, it is recommended that you get in contact with a local exterminator. Chances are that he/she will know just what type of solutions to use and how to get the job done in due time.

One good piece of advice that you should put into practice is that you should always look for reviews before hiring help. This way, you can get a better understanding of whether or not the selected firm can be trusted or not.

To find help, it is best that you go online and search for local firms. This way, you can also read the reviews left by previous customers.
