Through salt spray, your vegetables get a good amount of these nutrients that help them grow and thrive. 

Another benefit of using a salt-based insecticide is that it does not leave any awful odor or bitter taste on your plants. You can wash the excess salt from your veggies after harvesting and then cook them to perfection. 

The most common insects that homemade salt spray can deter include:

  • Snails 
  • Slugs
  • Beetles
  • Fleas 
  • Roaches 

Making salt spray is also quite easy. All you need to do is mix some salt in water per your vegetable garden’s needs and then pour the mixture into a spray bottle. If you are looking for an invisible, odorless insecticide, salt spray is one of the best organic insecticides for a vegetable garden.

You can then use it to spray on top of your vegetables and the underside of leaves. Make sure to apply the mixture to the base of your plants to deter insects from hiding there. You can use this mixture once or twice a week.
