5. Petroleum jelly
If you keep your pets’ food bowls in the kitchen, you’ve likely dealt with ants finding their way into any food that isn’t eaten immediately. You definitely shouldn’t use a store-bought repellent around your cat or dog’s food, so you need a pet-friendly remedy. Put a thin layer of petroleum jelly near the base of the food bowl. This will be too slippery for ants to crawl over, keeping them out of the food meant for the animals who are actually welcome in the house.
