If you’d prefer not to use chemicals, you should know that there are a lot of other ways to take care of a grub problem. People have been dealing with grubs for hundreds of years, long before commercial pesticides were invented. If you start looking into natural pest prevention methods, you’ll find all sorts of options.
As mentioned above, not all grubs are the same. If you’re going to focus on getting rid of your grubs in a natural way, you’re going to want to use a method that was designed for the type of grubs that you have. For example, some types of grubs are repulsed by citrus smells. If you apply a citrus spray to your plants, you may be able to keep those kinds of grubs away. However, this method might not be effective for other types of grubs.
