The study is aimed at examining the insecticidal properties of aqueous extracts of garlic at different concentration (10, 20, 30, 40 and 50 mg). The grains were kept open for infestation. The results showed a very high effectiveness of different concentrations of garlic aqueous extract on post-harvest pest of Beans (Callosobruchus maculutus) and Maize (Sitophilus zeamais). S.zeamais recorded mortality total rate of 49(98%) when compared to the C.Maculutus which had 43(86%). Increase in the concentration of the garlic aqueous extract also showed an increase in mortality of both post-harvest pests tested. In the Analysis of Variance (ANOVA), the F-distribution calculated which was 0.195 for the mortality of both post-harvest pests is less than that which was tabulated at (4.84), this implies that there was a relationship between the extracts and mortality of Sitophilus zeamais and Callosobruchus maculutus.
