However, to prevent their return, you may also need to carry out some minor repairs.
Start by inspecting the walls for cracks, holes, or other points of entry. These openings often serve as gateways for cockroaches from neighboring areas. Use filler or sealant to close them up immediately. This step is crucial in stopping new pests from invading your space.
To further reinforce your home, cover all ventilation openings with fine mesh tulle or a screen. This will prevent cockroaches from slipping through these hidden pathways.
To effectively lure and eliminate cockroaches, prepare a homemade bait using common ingredients:
Boil a thick semolina porridge.
Mix it with sweet tea to make it more appealing.
Add boric acid powder to the mixture, a natural insecticide.
Roll the mixture into small balls.
For best results, place these bait balls in areas where you have observed cockroach activity. The sweet tea will attract the pests, while the boric acid will poison them.
Leave the bait out overnight. Within 24 hours, you should notice dead cockroaches throughout the house. Use a broom or dustpan to collect them and dispose of them properly.
Usually, one night is enough to rid your home of cockroaches. However, if you still notice a few, you can repeat the process for complete extermination.
