Three sets of Concentration 2.5%, 5% and 7.5%were tested. Percent mortality was recorded at intervals of time for each plantextract. Data analysis was made by using Complete Randomized Design (CRD).The results showed that mortality effect varies according to extract type,concentration and time period .The time 12 h showed higher insecticidal effect withthe tested plants, Strong toxicity effect was observed at concentration 7.5 %. TheLT50 values were 1.10, 1.05 and 0.30 for Mentha arvensis and 1.75, 1.48 and 0.90for Nerium oleander.
