Ants can be extremely difficult to get rid of, and unfortunately, DIY ant pest control is mostly ineffective and can be dangerous if not used properly. If you spot one ant or a trail of ants in your home, follow the trail to locate their entry point. Entry points can include baseboards along walls, underneath doors, plumbing fixtures, and cabinets. Seal entry points with a silicone-based caulk and spray undiluted vinegar along the trail. Repair leaky plumbing and eliminate food sources by storing foods in containers, cleaning floors, and sanitizing all surfaces. Always call your local ant exterminators when you are having recurring infestations.
