The insect pest is also responsible for heavy damage to museum specimens and historical books. Among these insect pests, silverfish are well-known pests of houses, libraries, museums, and commercial places, feeding on and damaging a variety of food, such as clothing, paper products, paste or glue, as well as books. They can be a problem in libraries and other places where books, documents and papers are stored. Therefore in this study, lemongrass essential oil was investigated as insecticidal activity against silverfish. Insecticidal bioassay results of lemongrass essential oil indicated that no mortality was recorded in adult silverfish treated with all concentration of lemongrass essential oil for 15 minutes. But with increasing concentration of lemongrass essential oil and increasing treatment duration, the number of silverfish decreased. Maximum mortality was recorded at high oil concentration and higher treatment duration. The increase of ROC (%) is directly related to the increase of oil concentrations and treatment duration. An increase in ROC (%) was effectively recorded after treatment duration of 30 minutes. The increase in ROC (%) is minimum when the silverfishes are treated at 0.3 ml oil concentration for 15, 30, 45 & 60 min, 0.3 ml for 15, 30, 45 and 60 minutes and maximum ROC (%) recorded when treated at 0.9 ml oil concentration to be done.
