Kill cockroaches with boric acid.
Boric acid is a white powder used in household remedies for cleaning a dog's ears and eliminating pests. The powder works to kill and repel many bugs, such as cockroaches, ants, fleas and termites. The bugs eat the boric acid, which kills them. It is used in dog`s ears to eliminate any ear mites or other bugs. Boric acid is mildly toxic, so it is not recommended as a regular cleaner.
Instructions
Dog Ear Cleaner
1. Mix 16 oz. witch hazel, 4 tbsp. boric acid powder and 16 drops gentian violet in a clean glass jar.
2. Fill an eyedropper with the solution and slowly squirt it into the pet's ear. Don`t insert the eyedropper too deeply or you could damage the ear.
