Use steel wool to stop mice
Seal cracks or holes in wall and baseboards with steel wool, which mice and other household pests can’t chew through. Here are the things in your house right now that are attracting pests.
Stop ants with a natural barrier
Sprinkle a narrow, unbroken trail of cayenne pepper, black pepper, or salt across their path. Or draw a line with chalk.
Try ant-repellent herbs
Ants dislike the strong odors of certain herbs, so try placing pots of mint, pennyroyal, rue, or tansy—or dried bunches of these herbs—near trouble spots. You can also frequently wipe down windowsills with oil of cloves or eucalyptus oil.
