Cockroach Killer Home Remedies
#1. Diatomaceous Earth as Home Remedy
Diatomaceous earth is fine dust made of diatoms which has silicon dioxide shells. The fine dust absorbs fats and oils from the outer layer of the hard shell that covers cockroaches and other pests.
The tiny particles of fine dust have abrasive edges that further break the shell down. As result cockroaches or pests are unable to retain moisture, they dehydrate and die.
- Use only food-grade diatomaceous earth which is nontoxic to humans and pets
- Do not sprinkle in the wet areas else the earth will be ineffective
- If you are using insect-grade diatomaceous earth, wear a dust mask, gloves and goggles to avoid irritating skin, eyes or lungs
#2. Baking Soda and Sugar to Keep Cockroach Away
The baking soda is poisonous which produces gas after reacting with water. Cockroaches are attracted by sugar smell and consume the baking soda.
The baking soda mixes with stomach acids and releases carbon dioxide rapidly. The rapid release of carbon dioxide destroys the internal organs and finally kills them.
#3. Boric Acid as Home Remedy for Cockroach
Boric acid is an inorganic insecticide that has higher concentrations of boron which make difficult for cockroaches to eat or step around.
Boric acid is not only toxic but has a positive electrostatic charge which causes powder particles to stick to the bodies of cockroaches.
The slow-acting property of acid allows time for the cockroaches to carry the poisonous powder back to their nests and infect other cockroaches.
When cockroaches ingest the boric acid the cellular lining of their stomach gets destroyed which finally kills them. This is the most lethal method of killing cockroaches as they have been seen developing resistance to commercial pesticides.
