Neem oil has a strong aroma, so when using topically it's advised to dilute it in a 1:1 ratio with another carrier oil.

Massage a small amount of diluted neem oil onto your legs, arms, and other exposed body parts to repel insects. It can also be applied to your pets’ skin and coat to repel fleas and other insects.

Use neem oil topically to treat nail infections, cuts, redness, inflammation, acne, and itchy skin.

To treat head lice, massage diluted neem oil into the scalp and hair. Cover with a shower cap and leave in overnight. The next morning, comb the hair before washing with shampoo.

Use neem oil to make a natural anti-microbial cleaning spray. Combine 1 tablespoon neem oil, ½ cup pure vodka, and 1 cup water in a spray bottle. Use this to clean surfaces, windows, floors, and furniture. Spray it onto your bed and linen to eradicate fleas and bed bugs.

To make a natural insecticide spray for the garden, mix 5ml (1 teaspoon) neem oil,
2ml liquid soap, and 1-liter of water. Store this in a spray bottle and use the mixture
on your plants within 8 hours of making.
