    Finding cockroaches in your home can be frustrating and also hazardous to your health. They tend to carry bacteria and allergens that can affect human health as well as the health of pets. The primary concern is to find ways to get rid of them. Though professional help can make the task easy, you can try some budget-friendly DIY methods. This blog will explain a few effective and practical DIY methods to get rid of roaches overnight.

    Why Do Roaches Invade Homes?

    Roaches are drawn to food, water, and shelter, which they get in abundance in your homes, giving them an ideal environment. They often enter through small openings and hide in the dark, making it hard to detect them. They are mostly active at night and reproduce quickly. This is the primary reason for the infestation to spread quickly.

    DIY Solutions for Best Results

    The Boric Acid

    Boric acid is considered one of the best home remedies to prevent cockroach infestations. Here is how to use it as a DIY solution:

    • Take a mixing bowl, add 2 parts of boric acid powder and add 1 part of flour. The flour you choose can be rice, whole wheat, or white flour.

    • Take enough Karo syrup (or any sweetener as a substitute) to form a peanut butter-like consistency.

    • Mix thoroughly using a popsicle stick. Place the mixture in areas where roaches are commonly seen.

    It is important to prepare the mixture outdoors and wear a dust mask to avoid inhaling boric acid powder. Avoid contact with the eyes or accidental ingestion.

    Mix Borax and Sugar

    Borax is another popular option for dealing with roaches. The combination of borax and sugar creates a powerful homemade bait for roaches. Here is how to use them:

    • Take three parts of borax with one part sugar. Mix them together

    • Spread the mixture at places where you often see roaches. This could be underneath sinks, behind appliances, or in the dark corners of your home.

    Sugar in the bait attracts the roaches. Borax in the bait slowly dries out their exoskeleton and kills them.

    Vacuum the dead roaches right away. Avoid touching them with your bare hands. Lastly, make sure to keep the borax out of reach of children and pets to avoid accidental consumption.
