Termites are the most serious pests of field and horticultural crops, forests, and wooden household furniture. In Hamelmalo Agricultural College (HAC) the infestation of termite is very high resulting in great destruction of crop plants and wooden office and dormitory furniture. The devastating attack of termites should be managed by using best and ecofriendly management method. The purpose of the study was to compare the effectiveness of manual destruction of mounds and killing of termite queen and king, chemical chlorpyrifos, seed and leaves extract of neem and Lantana (as separate experiment) and smoke on termite control. Termite mounds were selected randomly inside HAC compound. The materials used were hand hoe, spade, fork, water, 20 L jar and protective clothes. The treatments were replicated three times. The botanical treatments were prepared at 2 L of highly concentrated extracts per 20 L of water each. Chlorpyrifos was applied at 20 ml per 20 L of water. Dried woody plants were used for smoke treatment. Careful digging was done to avoid king escape and queen rupture and they were killed by burning. Among all, the mechanical destruction and killing of king and queen and chlorpyrifos resulted in a complete control of the termite population. Except in the mounds treated by chlorpyrifos, the activity of termite population was very active and they closed the opened galleries immediately after treatment even though there were dead termite castes in all treatments. Living termite castes were counted by taking a medium size spade of broken mound pieces. The highest count was recorded from mounds treated by smoke. After two weeks the queen and king in every treatment mound were cheeked and killed for those who were alive. Except by the chlorpyrifos and manual destruction of mound (king and queen were killed before) all the royal families were alive and killed. Controlling of termite population in the field (outside their mound) is not possible due to the hidden fora
