How To Choose the Best Roach Killer for Your Apartment

Controlling or eradicating a cockroach infestation isn’t easy. Cockroaches can hide in various places which are hard to reach and often breed quite easily. Additionally, they can adapt to various challenges thrown their way, which makes killing them all the more difficult. 

Thus, the main factors you need to consider before choosing a roach killer for your apartment are:

  • Safety risks
  • Cost
  • Ease of use
  • Effectiveness
  • Other targeted pests

Safety Risks

Products used as roach killers often contain very harmful chemicals. You need to consider the risk the roach killer poses to you, your kids, or your pets. It’s important to pay attention to the warning labels or any safety information on the roach killer before making a purchase decision. Ensure that you use the spray away from kids or pets.

Roach killers should never be mixed with other chemicals, as this may cause a hazardous reaction. It’s important to follow the instructions on the label when using roach killers, as they can be dangerous if not used correctly.


The price of roach killers differs based on various factors, including effectiveness and type. Sprays, tablets, gels, and baits all have varying prices. Roach killers with a higher price tag are often more effective at eradicating roaches. If you rent your apartment, consider talking with your landlord to minimize the costs you will incur.

A building with numerous tenants will likely have a cockroach infestation in more than one apartment. It will drive up the cost of eradicating the cockroaches, and you may need to buy a higher quantity than you had initially planned.

Ease of Use

Select a roach killer that is easy to use, especially if you will be applying it yourself. Traps are usually very easy to use because you just have to set them up where the cockroaches often frequent. Sprays and gels are also not difficult to use because you can apply them where the roaches are hiding.

Powder solutions used in killing roaches, such as boric acid, are a bit complex as they involve preparation and cleaning up afterward. These solutions are often a great option if you need to eradicate some roaches in an outdoor area.


You should check the ingredients on any roach killer to determine its effectiveness at killing roaches. Some products are highly effective because the active ingredient breaks down quickly after application. Sprays are arguably one of the most effective roach killers, but they are not efficient at permanently dealing with a roach infestation.

Poison and traps are the best options for dealing with a large infestation of roaches. The efficacy period of most roach killers varies from 1 month to 2 years. Roach killers that work slowly are more effective at killing a large population of roaches. For instance, boric acid can eradicate the whole population but works very slowly.

Other Targeted Pests

Cockroaches don’t live in isolation, and you will likely find one or two other pests alongside them. Consider roach killers that kill other pests, such as ants, mice, and hornets. Some traps are useful for catching both roaches and rats.

Many roach killer products will have a list of pests they can kill. Thus, you should find out what other pests you can eliminate before making a purchase decision.

Dangers Roaches Pose to Your Apartment

Cockroaches are a health hazard when present in your apartment or home. Roaches can carry germs or bacteria that may make you or your loved one sick. Roaches can cause allergic reactions in some individuals, such as coughing, sneezing, and watery eyes. People with asthma risk suffering an attack if they come into contact with cockroach feces or dust.

Roaches contaminate food and surfaces with their feces, which can cause food poisoning and other illnesses. Roaches can spread Salmonellosis and cholera, which can be fatal. Allergies and allergic reactions are likely to increase with cockroaches in the apartment.

What Brings Roaches to Your Apartment

Noticing a roach infestation for the first time is not quite shocking. But repeated roach infestations, even after extermination, should make you question what makes your apartment so attractive to pests despite being clean. Some of the reasons roaches will find your apartment appealing include the following:

  • Availability of food
  • Water or moisture
  • Presence of clutter

Availability of Food

Cockroaches can eat almost anything from grease to wallpaper paste. Even if you keep a clean kitchen, you shouldn’t be surprised to see a few roaches.

Presence of Water or Moisture

Locations with high humidity will likely attract roaches as they need moisture to survive. Ensure your apartment has no leaky pipes or areas, such as the laundry room, and the kitchen remains dry. Consider keeping such areas well-lit because roaches like to make their nests in dark or poorly-lit locations.


The presence of too much clutter in your apartment will attract roaches. Make sure you regularly dispose of anything you don’t need. The buildup of clutter will offer a suitable habitat for roaches and encourage them to breed.

Alternatives to Commercial Roach Killers for Apartments

An alternative to commercial roach killers is natural remedies that don’t contain any toxins. You can create roach killers on your own using ingredients available in your home. Here are some remedies to roach infestation you can make on your own:

  • Borax
  • Essential oils
  • Onions and baking soda
  • Boric acid


Borax is a powder often used as a laundry product. You can use Borax to eradicate roaches by combining them with sugar. Leave the mixture in locations where you know roaches will find it. Remember that you should keep it away from pets and children.

Roaches cannot get attracted to Borax, and it has to get ingested to eradicate any infestation; therefore, you need to mix it with something roaches like, such as sugar. Borax kills roaches by causing dehydration due to the presence of Sodium Tetraborate. Borax is not a fast-acting killer of roaches. But you will notice a drop in the roach population 1 or 2 weeks after making the mixture.

Essential Oils

Essential oils in peppermint and citrus are helpful in repelling roaches. Cockroaches despise the scent produced by these essential oils.

Onions and Baking Soda

A mixture of onions and baking soda can help kill any roaches you have seen running around the apartment. Cut up some onions and place them in a dish. Add baking soda to the onions and place the dish where it’s accessible to the roaches.

Baking soda is an effective roach killer capable of causing death one day after ingestion. Thus, baking soda helps manage a roach infestation without the use of commercial roach killers.

Boric Acid

Boric acid is one of the most effective substances in killing roaches and features as one of the main ingredients in some of the best roach killers for apartments. You can create a mixture of boric acid and peanut butter or mix it with sugar and flour. Once you have prepared the mixture, place it near a roach nest.

After exposure or ingestion, boric acid will take three days to kill a cockroach. The solution is helpful in dealing with infestations because roaches often come into contact with the boric acid powder and then return to their nest. 


Some of the frequently asked questions on roach infestation and control are:

Why is it difficult to get rid of cockroaches?

The main reason it’s difficult to get rid of cockroaches is that they breed quickly. Roaches can hide virtually anywhere, making it hard for pesticides to work effectively. Cockroaches can adapt to various situations quickly and may even develop resistance to some pesticides.

What preventive measures can you take to ensure roaches don’t infest your home?

  • The following are measures you can take to prevent a cockroach infestation:
  • Keep food in sealed containers
  • Empty garbage cans every day
  • Ensure your kitchen and other areas of your house are dry
  • Clear away any waste from your house, especially food sources

How much time does it take to eradicate cockroaches?

The time it takes to eradicate roaches will vary based on a few factors, such as the potency of the pesticide used and the number of roaches in the nest. Eradicating one or two roaches will not take more than three days.

Ensure you keep using the pesticide until the roaches have been completely eradicated. Failing to do this will often lead to a never-ending cycle of infestation as the roaches left behind breed and increase in number.
