GETTING RID OF TERMITES

People keep telling me that used engine oil would help to get rid of termites.  Since the wooden fence of the Herb Garden was infested with termites, I decided to follow the advice and hope that it would be effective to keep the termites at bay.
During recess time this morning, two of my students from 4JER1, Lan and Ikhram helped me to dig holes and then pour the oil into it.  Hopefully, it works.
