What’s eating my pepper plants at night? 8 possible offenders

Pepper plants can bring vibrant color and flavor to any garden. However, they are also susceptible to a range of pests, especially those that feed during the night. While you may easily spot insects or damage during the day, many pests prefer the cooler, darker hours to feast on your plants, leaving you frustrated with damaged foliage or fruit when you inspect your garden in the morning. Understanding what’s attacking your pepper plants at night is the first step toward protecting your crop.

Read on to learn about eight common nocturnal pests that may be damaging your pepper plants, how to identify their presence, and strategies to prevent further harm.

How to Identify What’s Eating Your Peppers at Night

Identifying the culprits responsible for eating your pepper plants at night requires a bit of detective work. There are a few methods that can help you pinpoint the pest problem:

Monitor for Larger Animals: If you suspect larger animals, such as rabbits or deer, you can set up motion-activated cameras near your pepper plants to capture photographic evidence of these nocturnal visitors.

Nighttime Inspections: One of the easiest ways to catch pests in the act is to visit your garden at night with a flashlight. Many nocturnal pests such as slugs, snails, and caterpillars become active after sunset, and you might spot them directly on your plants.

Examine Damage Patterns: Different pests leave distinct types of damage. For example, small round holes in leaves might indicate insect feeding, while larger areas stripped of leaves suggest damage from larger animals like deer or rabbits.

Slugs and Snails

Slugs and snails are common nocturnal pests that can cause significant damage to pepper plants, especially young ones. These slimy creatures typically feed on the leaves, leaving large, irregular holes. They are most active during damp, cool nights and often leave a telltale slime trail as they move.

How to Identify Slug and Snail Damage:

• Large holes in leaves.
• Slime trails on the soil or plants.
• Activity mainly at night.

Prevention: Hand-pick slugs and snails off your plants during nighttime inspections. You can also use barriers like copper tape around plant beds or apply diatomaceous earth around the base of your plants to deter them.

Cutworms

Cutworms are caterpillars that feed on plant stems near the soil line, often causing entire plants to collapse. These pests are active both day and night, but their most destructive feeding tends to occur during the nighttime.

How to Identify Cutworm Damage:

• Severed stems, often near the base of the plant.
• Wilted or collapsed plants in the morning.

Prevention: Create a physical barrier around the base of your pepper plants using cardboard collars or similar materials. Regularly check the soil around the plants for cutworms and remove them by hand.

Hornworms

Hornworms are large caterpillars that feed on pepper and tomato plants, stripping the leaves and sometimes eating the fruit. While hornworms are often active during the day, they can continue feeding into the night.

How to Identify Hornworm Damage:

• Large sections of leaves missing.
• Hornworms visible on leaves or stems.
• Sometimes spotted during the day as well as at night.

Prevention: Hand-pick hornworms when spotted. If you see hornworms with white bumps on their backs, leave them alone—these are parasitic wasp larvae that will eventually kill the hornworm and help control the population.

Earwigs

Earwigs are nocturnal insects that may nibble on pepper plant leaves, but they can also be beneficial by eating pests like aphids. If the damage is minimal, it may be best to leave earwigs alone. However, if you notice significant feeding, you may need to intervene.

How to Identify Earwig Damage:

• Small, irregular holes in leaves.
• Nighttime feeding behavior.

Prevention: Use oil traps to attract and capture earwigs. Simply place a small container filled with vegetable oil near your plants. The earwigs will be drawn to it and become trapped.

Asiatic beetles

Asiatic beetles are another nocturnal pest that feeds on pepper plant leaves. Unlike Japanese beetles, which feed during the day, Asiatic beetles prefer to feed at night, creating small, ragged holes along the edges of leaves.

How to Identify Asiatic Beetle Damage:

• Irregular holes chewed around the edges of leaves.
• Nighttime activity.

Prevention: Hand-pick Asiatic beetles off your plants at night. You can also use a cup of soapy water to drop the beetles into as you remove them from the plants.

Rabbits

Although rabbits are not typically drawn to the fruit of pepper plants due to the capsaicin, they may still nibble on the leaves or stems, especially if other food sources are scarce. Rabbits are most active at dusk and during the night.

How to Identify Rabbit Damage:

• Leaves and stems chewed down, often close to the ground.
• Rabbit droppings near the plants.

Prevention: Erecting a low fence around your garden is one of the most effective ways to deter rabbits. A fence made from chicken wire or plastic garden fencing can protect your plants from these nibblers.

Deer

Deer can cause extensive damage to pepper plants by eating the leaves and stems, although they typically avoid the fruit due to the spicy capsaicin. However, in the absence of other food sources, deer may still graze on pepper plants, particularly younger ones.

How to Identify Deer Damage:

• Plants stripped of leaves, often down to the stem.
• Deer tracks or droppings near the plants.

Prevention: An 8-foot-tall fence is the best deterrent for deer. Deer can jump over shorter barriers, so a taller fence is crucial to protect your garden from these large herbivores.

Birds

Birds are attracted to the bright colors of pepper fruits and may peck at them, even though they are not affected by the heat of capsaicin. While birds are not nocturnal feeders, they may be active early in the morning, causing damage before you have a chance to inspect your plants.

How to Identify Bird Damage:

• Peppers with peck marks.
• Birds seen near the plants, particularly early in the morning.

Prevention: Bird netting can help protect your pepper plants from birds. You can also use reflective tape or other deterrents to scare them away.

How to Deter Nocturnal Pests from Your Pepper Plants

Protecting your pepper plants from nighttime pests involves using targeted methods depending on the type of pest.

• For Insects: Hand-picking is one of the most environmentally friendly solutions for controlling pests like slugs, snails, and caterpillars. Visit your garden after dusk to inspect for and remove pests. You can also use natural pesticides like diatomaceous earth or neem oil for larger infestations.
• For Larger Animals: Physical barriers like fences are the most effective way to keep larger animals such as rabbits and deer away from your pepper plants. Ensure the fence is tall enough to deter deer and securely installed to prevent rabbits from burrowing under it.

Understanding what’s eating your pepper plants at night is essential to protecting your garden. By identifying the specific pests causing damage, you can implement effective strategies to keep them at bay. Whether it’s hand-picking slugs, using traps for earwigs, or installing fences to deter larger animals like deer, there are many solutions to safeguard your plants. A proactive approach to pest management will ensure that your pepper plants thrive and continue to produce a healthy harvest.
