Natural Pesticides and Ants

Natural Pesticides and Ants | Science Fair Projects | STEM Projects
Do you want to know if natural pesticides like lemon juice are more effective than apple, tomato, or carrot juice against ants? In this science project, you will find out!


The hypothesis is that lemon juice is more effective as a pesticide, than apple, tomato or carrot juice, against ants.

Method & Materials

You will locate an ant hill, collect ants, prepare juices, draw circles, and observe if the ants cross the lines made from the juice.
You will need an empty bottle, black ants, gloves, a lemon, an apple, a tomato, a carrot, four plastic cups, and a juice extractor.


The results showed that lemon juice was effective in keeping the ants within the circle, while the apple, tomato, and carrot juices were not. This stands out as an observation.

Why do this project?

This science project is interesting and unique because it explores the effectiveness of natural pesticides against ants, which is a safer and more environmentally friendly alternative to chemical pesticides.

Also Consider

Experiment variations to consider include repeating the experiment with different types of insects like cockroaches or termites, and repeating the experiment using different types of natural substances like vinegar, saltwater, garlic oil, or tea.
