The efficacy of Fenugreek, Trigonellafoenum graecum, Celery, Apium graveolens Laurel, Laurus nobilis and Thyme, Thymus vulgaris extracts, against the four stored grains pests, rice weevil, Sitophilus oryzae, cowpea beetle, Callosobruchus maculatus, mould mite, Tyrophagus putrescentiae and house dust mite, Dermatophagoides farinae were investigated. Mortality (%) increased with increasing concentrations, exposure periods and varying from plant to plant. Petroleum ether extract of A. graveolens induced 100% mortality after two, eight and seven days of exposure for C. maculates, S. oryzae and D. farinae, respectively. Foenum graecum caused 100% mortality after four, five and seven days for S.oryzae, D. farinae and T. putrescentiae, respectively and 93.3% for C. maculates after five days. Petroleum ether extract of L. nobilis caused 100% mortality to C. maculatus, T. putrescentiae and D. farina but declined to48% with S. oryzae. T. vulgaris caused a complete reduction in F1- progeny for C. maculatus but had no effect against S. oryzae moderate effect on T. putrescentiae and D. farinae. A. graveolens and T. foenumgraecum were the most toxic plants followed by L. nobilis; while T. vulgariswas the least. For all plants, petroleum ether extracts were more effective in mortality percentage and reduction in F1- progeny than acetone extracts.
