How to Use Orange Peels to Kill Ants


There are quite a few types of commercial insecticides used for killing ants in and around the home. However, these can be toxic and aren't always the best choice for those who have pets or small children. Making orange peel insecticide is a natural alternative to commercial sprays and powders. The citrus oil in the peels gets rid of ants and keeps them from returning. It's best to apply the solution to the anthill early in the morning so that the majority of the ants are still inside.

Step 1

Peel two to three oranges. Use the fruit for another purpose and discard pieces of the white pith that aren't connected to the peel.

Step 2

Place the orange peels in the blender pitcher and add about a quarter-cup of warm water. Cap the blender and puree the peels and water on high for about 90 seconds.

Step 3

Add more water to the orange peel insecticide about a tablespoonful at a time until the mixture is an easily poured liquid.

Step 4

Locate the anthill outside and pour the orange peel ant killer directly into the top opening in the colony. It's OK if some of the solution doesn't make it into the anthill, as it will eventually sink into the dirt.

Step 5

Repeat the treatment as needed. If there is more than one anthill in the yard, it's important to treat each of them with the orange peel insecticide to control the ant situation.

Tips and Warnings

  • Be careful not to come in direct contact with the anthill. You might want to wear gloves.
