Respected Hakim Sahib, As Salam Alaikum!
I heard this from an old lady that if almost eight to nine inches long camel bone is buried in the termite affected earth, the trees, plants, flowers and grass and every wooden object will be protected from termites. There is no harm if the bone is smaller than the suggested size. We tested it in a few houses in termite affected areas; with Allah’s grace, those places were protected. The grass and plants turned lush green, we are still experimenting it.
