Step 5: Remember that even insects are thirsty, so make sure you don’t give them a chance to take fluid. Any spring of water, even a few droplets, is enough to attract them.
Step 6: Identify all the cracks in the house and seal them off. The least poisonous way is silicone.
Step 7: Prepare the natural repellent by mixing lemon peel with water and spraying on heavily frequented areas.
Step 8: When you have seen cockroaches in the pantry, empty them and clean them well with water to which you have added some lemon juice. Then put half a lemon in the closet as it is. Let it stand for 2-3 days and then replace it with a fresh one.
Step 9: Create a self-made trap to kill cockroaches. Mix a part of boric acid powder (you can find it in the DIY), a part of white flour and a part of sugar. Mix well until a kneading-like dough is formed. Place balls of this paste in the different areas of the house you have often ventured into. The flour and sugar in the mix attract cockroaches, and boric acid kills them. You can also produce a similar trap with a ratio of 1 part of boric acid, 1 part cocoa and 2 parts white flour. Use this trap for at least two weeks to make sure that all cockroaches have disappeared. WARNING: Keep this mixture out of reach of children and pets, as it is very toxic.
