Rid my exterior lawn/driveway/ sidewalks of ants ?
Diatomaceous earth, borax mixed with sugar, pouring boiling water repeatedly down their nest site, or applying a chemical spray for ants such as Ortho should solve the problem.
There are ant spikes you stick in the area. They eat it and take traces back to nest. Also you can buy "Home Defense" spray to cover the area.
Find the nest and pour boiling water on it.
I read somewhere that ants will be killed by eating cornmeal, its worth a shot!
There are a couple posts here that could help:
First and foremost, sources of attraction include any food that’s left sitting out, so make sure to keep your kitchen tidy and wipe down counters to get rid of crumbs or residue. Keep all pet food sealed in an air tight container and get rid of any leftover food in their bowl.
Vinegar. Mix three parts white distilled vinegar with one part water into a spray bottle. Next, locate the entrance points where you notice the ants have made their way into your home. Spray liberally around the entrance points and reapply daily until you no longer see any evidence of ants.
Food grade diatomaceous earth (FGDE). Even though it sounds like something out of a science fiction novel, food grade diatomaceous earth is a natural substance that’s harmless to mammals – but very harmful to ants. It’s easily found most home improvement stores or even on Amazon FGDE is commonly used by farmers to kill off insects in grain storage, so chances are you’ve actually ingested some over the years. Simply sprinkle some around any entrance point or ant hills you’ve located to get the job done. Also, be sure to purchase the food grade quality of diatomaceous earth, as the non-food grade is harmful to breathe.
Cornmeal. Cornmeal is a very effective, natural way to destroy a colony of ants. Much like food grade diatomaceous earth, cornmeal is harmless to humans but fatal for ants. Spread cornmeal liberally around where you see any type of ant hill or evidence of an ant colony. The ants will eat the cornmeal or take it back to their colony to eat later. However, instead of getting a free meal, this will kill of the ants due to their inability to digest the cornmeal. It does take longer to work than a pesticide, but it’s safe to use in a house with small children or animals.
Essential oils. The smell of certain types of essential oils can stop an ant dead in its tracks. Some of these oils include eucalyptus, cinnamon, clove, peppermint and citrus. Mix a spray bottle with equal parts water and one of these essential oils. Spray down any entrance points and repeat the process a few more times after the mixture has dried to create a solid barrier.
Herbs and spices. Sticking with the same concept as essential oils, there are several herbs and spices that ants will avoid due to their strong scent. Powdered cinnamon, clove, garlic, cayenne pepper, black pepper, mint or bay leaves all have the ability to repel ants as they work their way into your home. Sprinkle some around any entrance points to keep ants away.
Borax and sugar. Make sure to use a small amount of Borax when making this ant bait. In a bowl, mix together two cups of sugar, one cup of water and two tablespoons of Borax. The sugar will attract the ant while the Borax will slowly kill it as it wanders back to the colony. Place the mixture in small saucers around the house or near any entry points.
Boiling water and soap. Fill a medium pot with water with enough room left at the top that it can be carried for a distance. Bring the water to a boil and stir in about a cup of liquid dish soap that is environmentally friendly and biodegradable. Once you’ve located a series of anthills that indicate where the nest is, pour the water down one of the hills. The mixture should flush out most of the colony, but repeat as necessary if you notice any more ants.

If you can find the ant hills, you can destroy the hill. Borax or (my favorite) diatomaceous earth applied at the trails and hills will kill them. Good luck and stay safe!
I'd get ant killer poison.
Hi Newie: This is what I used for my ant problem, it may work for you, too.
Make a mix of 1/2 baking soda and 1/2 powdered sugar. Mix well and put around the spots they are in your garden, or inside your home, it's harmless to people and pets. For outside use, you can put it in a bottle, like a pill bottle or something like that. Cut a hole on the edge of the cap, and lay the bottle on it's side so the ants can come in and get the mix. This way, it stays dry if it should rain. They will take it back to the nest and it should kill them. I'd keep it out there all season if you can. The mix makes a gas and the ants can't pass gas, so it kills them. Anything else that eats it will just taste the baking soda and say "Yuck" and walk off. It won't hurt anything that can pass gas, so it's completely safe. It helps to know what type of ant you are trying to get rid of, too.
