Why Do My Basil Leaves Have Holes

Basil leaves with holes often mean bugs are munching on them. Leaves that look like someone took tiny bites from them can be the work of Japanese beetles, slugs, snails, aphids, or whiteflies.

These little critters love basil just as much as you do! Spider mites and flea beetles also create small holes in leaves. Pests like these can sneak up on your basil when you least expect it.

Sometimes, other things cause trouble too. Fungus or bacteria might attack the plant if the leaves stay wet for too long. Make sure your basil gets enough air to dry off after watering! Keeping plants healthy is key – strong basil can handle pests better than weak ones.

Watch out for signs of damage so you can jump into action fast if needed!

What’s Eating My Basil Leaves?

You might be surprised to find out that your basil is quite the snack for a variety of garden critters; let’s dive into who could be behind those mysterious holes.

Japanese beetles

Japanese beetles love to munch on basil. They can quickly chew through leaves, leaving behind holes or a lacy look. These bugs are not picky and will eat lots of different plants. They even hurt grass by eating the roots, making it turn brown and die.

If you spot these shiny pests on your basil, you can grab them with your fingers. Drop them into soapy water to stop them from doing more harm. This simple step helps protect your basil and keeps your garden healthy without using harsh chemicals.

Slugs or snails

Slugs and snails love munching on basil leaves. They sneak in at night and leave behind holes, sometimes big ones. Their eating can make the leaves look like someone cut out shapes with scissors.

If you see slimy trails near your plant, that’s a big clue they have visited.

To keep these pests away from your basil, try some tricks. Sprinkle diatomaceous earth around your plants; it’s like sharp glass to slugs and snails but safe for the plant. Iron phosphate pellets also work well to stop them without harming other animals or the soil.

Setting up a beer trap is another clever idea – they crawl in, attracted by the smell, and can’t get back out. Remember to check your traps every day! These methods will help protect your basil so you can enjoy its fresh taste without holes.


Aphids are tiny bugs that can be many colors like green, yellow, or red. They love to eat plants by sucking out the good stuff inside the leaves. This can hurt your basil and make holes in it.

If you see these pests on your plant, they might be causing the trouble.

You have ways to fight back against aphids and help your basil stay healthy. A spray made from insecticidal soap can push them away from your plant—neem oil works well too. Both choices are safe for people who like organic gardening.

Also, having insects that are friendly, like ladybugs, is smart because they eat aphids!


Whiteflies are tiny insects that love to eat basil plants. They suck the sap right out of the leaves, leaving your plant weak and with yellow spots. These bugs can even spread viruses that make things worse for your basil!

You might see a sticky mess called honeydew on your basil leaves — this is from whiteflies. It’s not just messy; it can also bring fungus that harms your plant. To stop these pests, try using insecticidal soaps.

Getting rid of whiteflies helps your basil grow strong and healthy again.

What to do with Damaged Basil Leaves with Holes?

Seeing holes in your basil leaves can be a sign of trouble. But don’t worry, you can fix the problem with a few simple steps.

  • Snip off the damaged leaves. Use sharp scissors to cut them at the stem.
  • Clean up fallen foliage from the soil. Remove any dead leaves to prevent more bugs.
  • Give your plant a gentle shower. Wash off tiny pests with water from a spray bottle.
  • Try natural remedies to keep bugs away. Sprinkle cayenne pepper around your plants.
  • Use garden fabric to protect basil. Cover it lightly to stop insects from getting close.
  • Prune your basil regularly. This helps the plant grow strong and healthy.
  • Add beneficial insects if needed. They eat bad bugs that hurt your plant.
  • For tough bug problems, use insecticides carefully. Pick ones safe for indoor plants like bacillus thuringiensis.
