Boracic acid can help you have a cockroach free home ecologically without the use of chemical pesticides. You can use boracic acid by itself or mixed with sugar to attrack the roaches. It is a stomach poison and affects the insects’ metabolism, while the dry powder is abrasive to the exoskeleton of the creepy crawlies. Place boracic acid in cracks and corners in the kitchen, behind the fridge and other appliances or cupboards, away from the reach of pets and nimble fingers of children.
Another ecological way to keep cockroaches away, is to place cucumber peels around the kitchen. They absolutely hate its smell!
