Roaches have a strong sense of smell and are repelled by a variety of potent aromas. Scents that can help deter them include citrus (such as lemon and orange), herbs like peppermint, mint, basil, thyme, and oregano, spices like bay leaves, cinnamon, clove, and garlic, as well as lavender, eucalyptus, citronella, tea tree oil, and vinegar.

You can use these scents in several ways to create an unwelcoming environment for roaches:

• Plants: Place mint or lavender plants in your home or garden.

• Powders and Leaves: Sprinkle garlic powder or place crushed bay leaves and citrus peels in high-risk areas like kitchens, bathrooms, and entry points.

• Sprays: Create a diluted solution with scents like lemon or vinegar to spray in your home. These can also be used in cleaning products or as room fresheners.

• Essential Oils: While essential oils of these scents can be used, be cautious as they can be toxic to pets if inhaled.

It is important to note that while these smells can help keep roaches away, they typically do not kill them and may not be enough to drive out an existing infestation entirely. For best results, combine these scent-based deterrents with regular cleaning. Be sure to clean up all food spills, crumbs, and dirty dishes promptly, and keep trash cans covered with a tight-fitting lid to remove potential food sources.

There’s little scientific evidence to suggest that homemade remedies to ward off wildlife are effective. But, often, when using them alongside other management techniques, it won’t do any harm to try. Suggestions include using urine-soaked kitty litter or sweat-soaked clothing items. Try applying them around your fence perimeters. Always read the instructions carefully for any commercially-bought repellents and opt for EPA-approved products. Multiple applications, especially after rain, are often necessary.

Any food that’s left out can potentially attract mice, but they especially like grains such as rice. Mice will also go after fruit, fatty foods like bacon, pasta, and cereal. Mice can also be attracted to garbage and compost bins if they’re left uncovered. The best way to prevent mice from getting to these areas is to keep food in hard-sided containers and cover garbage bins.

Yes, it’s possible for bats in your attic to find a way into your living spaces. Until you can properly remove the bats, the best course of action is to keep the attic doors closed and any holes sealed. Evidence suggests bats follow the airflow in your home, so they may try escaping from the attic to other parts of the house.
