The fragrance is lemony and bearable to most people but pungent to many insects, especially mosquitoes. Other essential oils that have insect-repelling properties are cedarwood, lemongrass, eucalyptus, peppermint, pennyroyal, lavender, and bergamot.

Below is a list of common pests and ways to use essential oils to repel them.


A common natural way to get rid of ants is by using vinegar. Put vinegar in a spray bottle and spray it where ants commonly appear. Black pepper or cayenne pepper can also be used to defend areas from ants by sprinkling it in places where ants show up. Peppermint essential oil can be sprinkled along areas of the kitchen or bathroom.


Mix 10 drops of both rosemary and lavender oil in 1 litre (4 cups) of salt water. Spray the affected plants. Most plants should be safe to apply the solution on them. Neem oil has repelent properties and keeps aphid reproduction down. Need oil has a bitter taste so aphids and many pests which eat garden plants will not attack plants which have been treated with it. Another natural aphid repellent is calcium powder. Sprinkle the powder around the plant’s base.


Get some cotton balls and drop a few drops of citronella oil on each cotton ball. Also consider adding peppermint oil or lemongrass as well. Then place the cotton balls in trouble areas such as cupboards or under the sink. You can also make a spray solution by adding a half cup of water and 5 drops of cypress essential oil and 10 drops of peppermint oil. Spray the solution wherever the cockroaches appear.


Get a bowl and place a handful of dried cloves in it. Sprinkle a few drops of clove oil, lavender oil, and citronella oil or peppermint oil on the dried cloves. Add the oils again regularly. Place in areas where flies may come or linger such as a front or back doors, kitchen, or near the garage.


Put a few drops of citronella oil or lemongrass oil in an oil burner. Using a citronella candle works well too. Get a ribbon and place five drops each of citronella oil, lemongrass oil, peppermint oil, and lavender oil on the ribbon. Hang the ribbon from doorways, patio, or a window.


Get some cotton balls and place a few drops of peppermint, eucalyptus, or spearmint oil on some cotton balls and position them where you suspect they are. Mice may appear behind appliances such as a fridge, washer, or dryer. Also place them in areas of a attic or garage. Look for places where mice may be entering the house and place cotton balls there as well. This can deter mice but further measures may be required if the infestation is serious.
