Natural pesticides and antsFeatured science projectScience project video

Conclusion

Out hypothesis that lemon juice is more effective as a pesticide, than apple, tomato or carrot juice, against ants, has been proven to be correct.

Using natural pesticides derived from plants, vegetables or fruits are a better and safer way of keeping insects at bay. Their effectiveness may be for a short period of time and they be a more expensive means of pest control, but they are safer and more environmentally. Regular use of chemical pesticides can be harmful to our health, especially to our children. These insecticides can enter our bodies through inhalation of fumes or the contamination of food and drinking water, causing various types of illnesses.

Also consider

Would your observations be different if this science fair project were to be repeated using different types of insects like cockroaches or termites?

The science project experiment can also be repeated using different types of natural substances like vinegar, saltwater, garlic oil or tea.
