Abstract

The ants and mealybugs are interrelated species, the ant protect the mealybugs from their enemies while
the mealybugs feed the ants with the nectar obtained from the plant. There two individuals cause the
nuisance and annoyance to human. Accordingly, the project was aimed to investigate the solvent type,
the optimal extraction time and the ratio of cayenne pepper and white holy basil on eliminating the ants
and the mealybugs. The results showed that 95% ethanol was the most effective solvent. The most
appropriate time for extraction was 72 hours. The pepper and basil at a ratio of 3:2 was the best
extraction for getting rid of the ants and the mealybugs. This insight knowledge could be applied for
developing the insecticide product.

Keywords: The effect of extraction on eliminate, ants, mealybugs
