3. Coffee grounds

Take coffee grounds and mix them with water in order that the coffee grounds are wet but not submerged, then divide the mixture into jars with lids and place them wherever you suspect there are insects. They will be attracted by the smell of coffee and will crawl into the jar. The caffeine in coffee can remove many types of insects, especially cockroaches.

4. Garlic

Cockroaches and mice are most afraid of this, put it in the corner of the room and no one will come near.
