This natural pest repellent is extremely effective and it gets better with time. Soak chopped onions, and chilies for at least 3 days before using to spray or splash in dark areas where the pests are. I use a pasty brush to spread the liquid inside dark cupboards and then I spread some of the liquid under the fridge. Then I clean after a day.

If there are many eggs, you will need to use it after every 10 days for a long time because regular pests lay a lot of eggs. This is great for cockroaches, bedbugs (kunguni), ants, flies etc. Basically any typical pest cannot stand the smell and they never want to come into contact with the liquid.
