How to Do Patch Test

Mixing tea tree oil for bed bugs is easy and only involves a few steps. Before you start using tea tree oil, make sure that it is safe for you. You can do this by running a quick patch test.

That way, you can quickly know whether you are allergic to the oil. However, you will need a day or two to get your results.

This is a natural step that entails choosing a patch of skin in an area that is not easily noticeable. You will test the oil on it and see how it reacts.

  • Place one or two drops of the oil in your inner forearm. This is the ideal area for patch testing since the skin is highly sensitive and cannot be noticed easily. Also, you will not run out the oil unknowingly.
  • For the test, you can use any dilution ratio. Try to use somewhere between 1-50%. Anything more than that might be too much and your skin might not handle it; hence, you will obviously get an allergic reaction.
  • Place a bandage on the area on which you placed the few drops of diluted tea tree oil.
  • Let it dry. If you start to feel irritation around the area, remove the bandage immediately, and wash thoroughly with water and soap.

However, if you don’t feel any irritation within the first 24-48 hours, then you are not allergic to the oil. Note that while you might be allergic to the oil, you might still be sensitive to a high concentration of the same.

After running the patch test successfully, you can go ahead and use the oil to kill bed bugs. If you learn that you are allergic to the oil, you can ask someone to do the work for you.

However, if there is no one to help, make sure that you cover your body well leaving no skin exposed to the tea tree oil during the application.
