Using natural pesticides to control termitesFeatured science projectScience project video

Conclusion

The hypothesis that boric acid and vinegar will be able to keep termites away,  is partially  correct. Only the boric acid (borax) was effective in keeping the termites contained within the circle.

Natural pesticides are made with substances that are derived from fruits, vegetables, plants or naturally occurring minerals. Natural pesticides may not be as long-lasting as chemical pesticides and they are also more expensive. However, they are safer to use and are less harmful to our environment.

 

Also consider

What would happen if the science fair project was repeated using different types of insects - eg. cockroaches or red ants?

The experiment can also be done using different types of natural substances like saltwater, garlic oil or tea.

Would increasing or decreasing the concentration of the acid solutions make a difference to your results?
