If you are using a Pest control service make sure they are Eco Friendly. We have pets, babies and our own health to consider when toxic sprays are used to repel insects. If you are noticing ants in your home there are a few household items that can repel the ants before the Eco friendly pest control service arrives. Remember: the ants do not wait for Pest control – they continue to feed. Determine where the ants are entering your home and sprinkle or spray the area with one of the following: Cayenne pepper, black pepper, cinnamon, a citric acid, cream of tartar or vinegar. Each one of these items repels the ants in one way or another whether it be by odor or taste.
