Now there are many ways to get rid of ants but if you don't want to spend money on it you can easily create your own "ant killer" just using some ingredients you have at home
Step 1: Step 1: Ingredients
2 teaspoons of dishwashing soap
2 teaspoons of cooking oil (any kind of oil will do the job)
400 ml of water
1 spray Bottle
Step 2: Step 2: Mix Everything Together
Now take a spray bottle and fill all 3 ingredients in it. Shake it well and you're ready to go.
It's just easy as that. Now take the bottle and spray along the ant trails or directly. Remember to re-apply it after some days as it's going to evaporate fast.
