How to Add Insecticide to Deer Repellent

By Alicia Bodine ; Updated September 21, 2017
Deer frequent properties in search of food.

You might already be using neem oil as an all-natural insecticide to keep insects away from your flower and vegetable gardens. But if you also have a problem with deer, you can add this same product to a deer repellent and spray it around your property. You can make this repellent at home without needing chemicals that might harm pets and children.

Place the water, garlic cloves, onions, and hot pepper powder in a blender. Blend until completely combined.

Pour the deer repellent into a container that has a lid. Place the lid on the container and let the mixture sit on your counter for one day.

Strain your deer repellent to remove any bits and pieces of the onion or garlic.

Add a gallon of water to the strained mixture. Then add neem oil to the deer repellent. Neem oil is an all-natural insecticide. Mix the ingredients together.

Pour the mixture into a spray bottle. Spray all over your property to repel deer and insects.
