  2. You need to do this every couple of hours, this will not only reduce the reddening and the irritation caused by the bites, but it will also help in healing quicker.
  3. However, sometimes people tend to be sensitive to these oils and hence it is better to first try the oil out on a small patch of your hand just to make sure that you don’t have any allergic reactions to it.
  4. Once sure, you can move ahead and use this all over your body to treat the bug bites.
  5. Tea tree oil is one essential oil that you don’t need to dilute before using. You can directly apply the drops on the bites itself but since it is oil, it is thick and sticky and might drip if applied in excess and so it’s better to dab them on your skin to avoid creating a mess.

Yes. Bed bugs cannot stand the strong and pungent odor that is apparent in all bottles of tea tree oil. Some people will simply open a bottle and leave it near their beds to repel insects.

Others will pour it oil into a bowl with water and keep it on the nightstand. We tend to rely on spraying tea tree oil with water in a spray bottle all over our bed and let it dry.

We like the smell, but bed bugs hate it and will wish to get a far away from it as possible before direct contact kills them.
