Natural Control of Ants

We are still getting used to our new house.  My last house had a seasonal ant infestation that I took care of with natural means and was able with a few modifications to keep them out of the house for the most part.

Here I had to start over.  We had the usual spring infestation when the ground warmed and they came in looking for food.  With a bit of work. I was able to end that in quick order.

Generally, I sprayed a vinegar mix in the areas they entered and sprinkled baking soda in the pathways to keep them from coming back.

Recently I have a new one, in my office by the window.  This is weird because the window is in a bumpout that does not reach the ground on the exterior of the house, so I am trying to figure out where they are getting in, so I can stop the invasion, but until I do I am using a number of different applications to keep them under control.

Controlling Ants Naturally

1. Distilled White Vinegar

A white vinegar and water solution is a common method to wipe out ants for good. Ants don't like the smell of vinegar. It not only repels them; it can also kill them. Depending on how much you can bear the smell, mix at least one part vinegar and three parts water. Some people use 100% vinegar in a spray bottle or a 50/50 mix of water and vinegar. You can stop with just plain white distilled, but since it is my office I opted for a thyme and lemon scented vinegar.  I can kill germs and the scent is more nose friendly as it is my office.

Ants search for food using pheromones, leaving a trail for other ants to follow. To get rid of the trail, spray this mixture anywhere you spot ants. Don't forget any entry points, like window sills, backdoors, or baseboards. Use the solution to wipe down and sanitize surfaces. If used once a week or so, you should see a marked improvement.

2. Citrus Fruits

Ants hate the smell of citrus fruits, such as lemons, limes, and oranges, so they're an excellent natural repellant. Save your lemon or grapefruit peels and scatter them around entryways. They act as natural deterrents without causing ants any harm.

3. Peppermint Oil

Peppermint oil is one of the best household remedies for creeping critters in your home or garden. The odor of peppermint is strong enough to ward off insects—ants, flies, and mosquitoes—without being pungent enough to cause headaches or nausea.  I created a spray using peppermint essential oil using it to wipe down the windowsills, wall areas and baseboards.  The scent is very relaxing.

Another option is to use an oil incense burner near the ant infestation source to keep them from coming back. 

4. Cinnamon

Studies show that cinnamon has a compound known as trans-cinnamaldehyde that effectively repels and kills ants. Place ground cinnamon around common entryways and its strong smell will act as a natural repellent. You can also coat cotton balls with cinnamon powder or cinnamon oil and place them near ant-prone areas. I sprinkle cinnamon on ant hills that are too close to the house or along the foundation so they relocate away from the house.

5. Salt

Spread table salt near nooks and corners to keep ants away. A line of salt or baking soda creates a barrier that repels ants. A spray of salt water solution can also help kill ants by dehydrating them. I use this once I figure out where they are coming in then I spray them as they enter and leave and take care of them.

6. Cayenne or Black Pepper

Like many people, ants find the smell of raw pepper to be irritating. Sprinkle pepper around the areas where ants access the house. A Texas A&M study found that a water and pepper solution was effective at killing ants.

7. Borax (sodium tetraborate)

Borax and boric acid are not the same chemical compound despite their similar-sounding name. But both may be equally as effective at killing ants in the home.  However, it is imperative to keep borax away from pets and children as it may be harmful.

To use borax, follow these steps:

• Put on safety gloves.
• Make a solution of 1/2 teaspoon borax, 8 teaspoons sugar, and 1 cup warm water.
• Stir until the sugar and borax are dissolved.
• Saturate cotton balls and place them around your home in areas where you commonly see ants.
• After use, wash containers thoroughly or discard.

Find borax in the laundry section of Walmart or the grocery store or at your local hardware store.

So once I kill them at the entry point.  I will need to take care of the entry point.

How to Keep Ants Out of Your House

1. Seal all entry points. Caulk and seal any cracks or exposed crevices where ants can access the house.

2. Keep sweets in airtight containers, tightly wrapped with foil or plastic, or in the fridge. And stop throwing food items out in the office trash that may not be picked up as often as the kitchen trash.

3. Regularly clean countertops, floors, cabinets, and pantries. Also, keep pet food properly stored between meals and regularly clean pet bowls.

4. Take out the trash and make sure that the trash cans are covered. Inspect the cans for residue that might linger after taking the garbage out and clean them regularly.

We know they came into my office due to a tossed out frosty cup in my office trash.  The sweet was a magnet for the ants. I took out the trash, treated the wall so they lost the scent track to the trash can and then went looking for where they came in.  My office is nowhere near the kitchen or the pantry or anywhere else that food is kept so the fact I still have the ants after removing the Frosty cup means there is another source that requires investigation.
