What Is Eating My Basil Plant and How to Prevent It

If you're noticing holes in the leaves or stems of your basil plant, it's likely being eaten by pests.

Aphids, whiteflies, and spider mites are common culprits that can cause significant damage to basil plants.

Basil is a favorite snack of many garden pests, including aphids, which can reproduce quickly and spread disease.

To prevent pest infestations, ensure your basil plants are receiving enough light and water, as stressed plants are more susceptible to pest attacks.

Most basil pests are insects that love the scented leaves and can't resist munching on the tender foliage.

Slugs and snails are notorious for eating large ragged holes in basil leaves, especially at night. They hide under mulch, plant leaves, and rocks during the day.

Aphids are small, soft-bodied insects that can be almost any color and may be found atop or on the underside of leaves and even on stems. They use needle-like mouthparts to pierce plants and feed on the sap.

Japanese beetles are easy to spot in sunlight due to their iridescent coloring and larger size. They overwinter as white grubs in the soil and emerge from the ground about mid-summer.

Armyworms and other caterpillars nibble on basil leaves, leaving behind their droppings. They tend to go for the tender new growth first.

Grasshoppers can be a big problem in some gardens, chomping on leaves and making holes in random locations across the leaf. Brush your basil leaves to knock loose any grasshoppers.

Larger critters, such as rats, can also find basil appetizing. Bird netting can help prevent these guys from snacking on your basil.

Physical barriers can be an effective way to keep pests away from your basil plant. Bird netting is a great option to prevent flying and leaping insects from setting up residence.

Garden fabric, also known as floating row cover, is another great choice that prevents moths and butterflies from laying eggs on plants. It's lightweight and easy to use, making it a popular choice among gardeners.

Critters can get stuck inside garden fabric, so be sure to remove it to inspect your plants every once in a while.

Deer are a common culprit when it comes to basil plant damage. They may grab a taste test, but quickly figure out basil is not a preferred flavor.

Deer damage typically looks like a torn stem, missing top, or even a whole plant ripped out of the ground. Hoof prints are a good sign deer have been there.

To keep deer at bay, you can use deer repellent frequently, switching the type every few weeks. This will help deter them from returning to your basil plant.

Installing tall fencing around the part of your garden you want to protect, or your whole yard if possible, can also be an effective solution.

To keep your basil plant healthy and pest-free, it's essential to cover it with row covers when Japanese beetles are imminent.

Keeping the plant consistently watered and fed will also help it grow strong and resilient to pests. Make sure to keep the area around the basil free from weeds and other detritus where pests might hide.

Armyworms and other caterpillars are common pests that can nibble on basil leaves, leaving behind their droppings. Check the undersides of leaves every few days to catch them early.

Grasshoppers can be a big problem in some gardens, and their babies are often hard to spot because they're the same color as leaves. Brushing your basil leaves can help knock loose any hidden grasshoppers.

Bird netting is a great way to protect your basil from larger critters like rats and even carpenter ants that might be gnawing away at the leaves.
