There are many choices to select from when in search for a natural deterrent for ants, but which ones actually work?

Although relatively harmless, ants can become a serious issue when they begin to invade your home, especially in the kitchen where leftover food scraps, spills, baked goodies and sugar are ripe for the picking.

Once infested, it can be extremely frustrating to deal with, as you may get rid of them one day but they soon return in numbers the next day.

The aim of the game is to repel the ants before they enter your home. We have devised a list of natural products and plants that you can implement immediately to help get rid of the current infestation and to prevent them from entering your home.

Natural products that repel ants

The strong smell of vinegar confuses ants by removing their scent and disrupting their trails, which prevents them from communicating with each other. Mix a 50/50 solution of vinegar and water into a spray bottle and Spray the solution around your window sills, doorways, and any other entry points you see ants coming inside from. Spray the solution directly onto the ants to kill any that have made it into your home. To prevent ants from ever returning, locate the nest and pour vinegar directly onto it. Alternatively, you can fill up a syringe up and inject it deep into the nest for safe measures. 

Lemon juice

Similar to vinegar, lemon juice also disrupts the scent trails that the ants use to communicate and follow. Create an all purpose spray using a cup of lemon juice and 2 cups of water and spray the solution around entry points of your home, or any areas where you’ve spotted ants.

What attracts ants into your home?

Knowing how to deter and kill ants is one part, preventing them from entering your home entirely is another. There are 3 reasons why ants will enter your home, knowing what these 3 major factors are will help you identify the source of the infestation, making it easier to exterminate.

  1. Food. Just like humans, ants need food to survive and it just so happens that our food has every bit of nutrition they need. Ants are 5 times more receptive than other scavenger insect and can sense food debris or leftovers that are left in the open. Make sure that all food scraps have been properly disposed of, as well as all leftovers glad wrapped and put away.

  2. Water. Like all living things, ants need water to survive, however they don’t need much. A little puddle or water leak, even food can be suffice. Check your home for any water leaks.

  3.  Shelter. Whenever ants leave the nest they are vulnerable. What may seem harmless to us is catastrophic to them. Cracks and crevices around your home are an open invitation for ants, as they seek refuge from heavy rainfall, wondering pets and other predators.
