1. Manual Removal
Your first step to removal is handpicking all of the caterpillars you find on your plants. It is a good idea to check your garden at night to find slugs and caterpillars. You can either drop them in a bucket of soapy water, killing them, or relocate them to a different area.
You should also check your garden for eggs frequently. Removing all of the fallen leaves and debris around your plants will deter caterpillars. If you find eggs on a leaf, pinch or snip off the leaf and remove from the garden.
2. Neem Oil
Many gardeners like to use Neem oil to control caterpillars and other bothersome pests. It is ideal for whiteflies, leafminers, and thrips. However, Neem oil may kill some important insects like bees and earthworms, so it is best to be cautious. To use Neem oil, you must spray the foliage with it.
3. Bring in the Birds
Even though you may want to keep birds from your berry patch, setting out bird feeders and encouraging birds to thrive in the area around your garden can help get rid of caterpillars. Chickens and ducks, if you have a flock, love these little insects! They are a tasty treat!
4. Bacillus Thuringiensis
Another natural method of removal is to dust your plant foliage with Bacillus Thuringiensis (Bt) powder. Bt can kill caterpillars but won’t do any harm to the insects your plants need. Bt is a bacteria that naturally occurs in soil. The bacteria infects and destroys the lining of their gut. Luckily, it is entirely non-toxic for humans and animals. Insects, such as caterpillars, will either stay clear of it or die. Bt is hard to find; you may have to find a specialty store or order it online.
5. Deter Cutworms
To avoid damage caused by cutworms, put a stiff collar around your delicate seedlings. A plastic cup or a toilet paper roll can serve as a collar to protect against these harmful caterpillars.
6. Shield Plants
Another way to get rid of caterpillars is to shield the plants with a sheet of porous polyester fabric. These sheets are porous and allow light to pass through to the plants, but they prevent any pests from reaching them. Making your row covers is simple, even though you can buy premade row covers. Stick hoops into the ground and cover with perforated plastic or fabric sheeting. Remember to weigh down row covers with bricks or other heavy items!
7. Plant a Border
If you think ahead, you can line the edge of your garden with certain herbs and flowers. Insects are deterred by the smell of certain plants like lavender, mugwort, sage and peppermint. These plants have strong scents, and they disguise the smell of the plants the caterpillars are attracted. The goal is to make them look elsewhere for their next meal. So, if you have a problem caterpillar, place a few of these plants around them!
8. Crop Rotation
Another natural way to get rid of caterpillars is by practicing crop rotation. It requires planning ahead of time. An example is not planting tomatoes in the same place two years in a row.
