    What Are The Causes of Cockroach Infestation In Your Apartment?

    Cockroaches are among the most common household pests. These nocturnal scavengers are the ultimate survivors of the insect kingdom and the most stubborn pests in many households that can trigger the spread of serious illnesses as they thrive.

    Although cockroaches prefer warm environments that are close to sources of food, the success of their species is mainly attributed to their ultimate adaptability. Whether you are living in an urban or rural setting, you can expect some crawling invaders if:

    • You have a couple of exposed food here and there
    • Dark and wet areas inside your unit
    • You let your trash linger inside your unit and uncovered
    • You have a lot of gaps and cracks in various corners of your apartment
    • You are living right next to a messy neighbor

    Is It Possible To Get Rid Of An Infestation In Your Apartment?

    Yes, of course!

    However, bear in mind that cockroach infestations are often hard to deal with especially if you are not equipped with a proper battle plan. Apartment buildings typically have shared walls and vents. These serve as major highways for cockroaches to easily thrive from one door to the next.

    Nonetheless, it still doesn’t mean that there’s nothing you can do to turn the tide. There are actually a number of home remedies that can help you get rid of these unwanted guests.

    You can sprinkle boric acid along corners, gaps, and underneath the furniture which are frequented by cockroaches. Boric acid is a popular cockroach poison that can kill the pest when it comes in contact with the chemical. Just make sure to keep it out of reach of children and apply only minimal amounts on target areas.

    Baking soda and sugar are another effective solution. This however, takes a little while before you can see some positive results. Other proven effective home remedies in battling out cockroach infestations are the use of fabric softener spray, bay leaves, and lemon peels.

    How Can You Keep Roaches From Invading Your Apartment?

    Killing cockroaches can be pretty simple and easy provided that you have the right tools to get the job done. But putting these nasty scavengers out of their misery is only half the battle. You also need to make sure that these cockroaches won’t be able to infiltrate your unit in the future.

    Seal up cracks and gaps

    With a flexible exoskeleton, it is quite easy for cockroaches to squeeze through gaps as narrow as 1/16 of an inch. Locate as many holes and cracks as possible throughout your unit and seal them up with a caulk that contains boric acid.

    Treat your baseboards with Diatomaceous Earth since it is also an effective remedy against cockroaches. Lastly, secure your unit with a door seal set to totally deny cockroaches any possible entry into your unit.

    Eliminate clutter and vacuum from time to time

    Cockroaches won’t be dubbed as the ultimate scavengers for nothing. In fact, these pests can eat almost anything inside your apartment including wallpaper paste as well as your books and hair.

    Keep your apartment clean and tidy all the time. Maintain an organized arrangement of all your things and vacuum regularly especially underneath your furniture.

    Secure your food

    As mentioned earlier, one of the main causes of cockroaches inside your apartment is exposed food. As much as possible, secure all of your food stuffs in a glass container that can be completely sealed.

    It is also wise to make sure that all food droppings and smudges on your dining table and inside the kitchen are wiped clean.

    Cockroach Warning

    If you do think you have cockroaches in your apartment, we highly recommend first consulting with a local exterminator before using sprays or any other method of cockroach control. Improper use can and will make your cockroach problem worse.

    Use our local exterminator search tool to get a couple free quotes so you can begin the removal process.
