You asked for tips to control termites. We often have termite in our home; we spray kerosene oil on it with syringe, it kills its worms. After this, we remove the termites from there and spray again. If it makes holes, we apply some kerosene oil on cotton bud and close the hole with it. The worms are killed immediately with kerosene oil. Moreover, we have also heard that termites are removed with sulfur fumes but we never tried it.
