What Is Eating My Pea Plants

So, you’ve been nurturing your pea plants with unwavering dedication, only to find something has been feasting on them. Without a doubt, diagnosing these leafy lunch thieves can feel like unravelling a complex botanical mystery.

Don’t despair though – your garden isn’t facing a whimsical apocalypse. It’s clear there’s an elusive, voracious culprit amongst the foliage. Who’s the naughty nibbler? Well, several critters may be responsible – let’s take a closer look.

What Is Eating My Pea Plants?

The most common pests that could be eating your pea plants are pea weevils and aphids. Pea weevils mainly feed on seeds and seedlings but can also cause damage to adult plants. On the other hand, aphids are small sap-sucking insects that attack all parts of the plant. Both pests can cause significant harm to your pea plants if left unchecked.

– Aphids

Description Small, soft-bodied insects with pear-shaped bodies and long antennae that suck plant sap, causing yellowing and curling of leaves.
Damage Leaf damage, wilting, stunted growth, yellowing leaves, loss of flowers/fruits.
Control Implement natural predators, such as ladybugs or lacewings, use insecticidal soap or neem oil, and practice crop rotation.

Aphid Damage
Aphids are a common pest in gardens, particularly for pea plants. They feed on plant sap and stunt plant growth by siphoning off nutrients, distorting new growth, spreading viruses, and secreting a sticky substance called honeydew which could lead to sooty mold.

Control Measures
There are several ways to manage an aphid infestation. Utilizing natural predators such as ladybugs, lacewings, and hoverflies can help control the aphid population. Spraying affected plants with a strong water jet will also dislodge aphids.

Furthermore, using insecticidal soap or plant-based oils (like neem) can effectively kill aphids without harming beneficial insects or the plants. For severe infestations, a pesticide specifically designed for aphids may be necessary. Applying an ant bait near your plants can also help since ants often farm aphids and protect them from predators.

Remember to periodically check the underside of leaves as aphids often hide in these areas. With consistent care and observation, your pea plants can recover from aphid damage and thrive.

– Slugs

Description Slimy, nocturnal pests with voracious appetites that leave irregular holes and silvery trails on pea plant leaves.
Damage Holes and chewed leaves.
Control Implement physical barriers, such as copper tape or eggshells, around the plants and apply organic slug repellents like coffee grounds or beer traps.

Slugs as Pests

The common garden slug is one of the primary pests that could be eating your pea plants. Slugs are known for their voracious appetite and can cause significant damage. They usually feed at night and prefer young, tender plants, like peas. Evidence of their presence may be visible as large, irregular holes in leaves and slime trails.


To control slugs, clean up garden debris and mulch that provide hiding and breeding places. Introduce natural predators, such as birds or ground beetles, or create a barrier around your plants with materials that repel them, like diatomaceous earth or crushed eggshells. You can also use a commercial slug bait or make a beer trap. However, remember that persistent monitoring and a combination of these methods is typically required for effective slug control.

– Snails

Description Small slimy invertebrates with shells, leaving silvery trails, grazing on leaves and causing significant damage to pea plants.
Damage Holes and chewed leaves on pea plants.
Control Protect plants with barriers, such as copper tape or crushed eggshells, and remove snails manually.

How Snails Affect Pea Plants
Snails are one of the common pests that enjoy dining on pea plants. They typically feed during the night or on overcast, damp days, leaving irregularly shaped holes or ragged edges on leaves and stems. Heavy infestations can defoliate plants, reduce yield, and even kill them. Snails are especially destructive in cool, wet conditions and can be a serious problem in gardens with heavy mulch.

Solution to Control Snails
Control of snails begins with regular garden inspections, especially in the evening when they are most active. Handpick and dispose of any snails found. A trap made of beer or yeast solution in a shallow container can also attract and drown snails. Barriers and deterrents such as copper tape, crushed eggshells, or diatomaceous earth placed around your plants can discourage snails. Biological control methods include species that are natural predators to snails such as certain types of birds and beetles. Commercially available snail baits or pesticides can be effective if used correctly, but always follow the manufacturer’s instructions. Lastly, remember to keep your garden clean to reduce hiding and breeding places for snails.

– Rabbits

Description Small mammals with long ears and sharp teeth, causing damage by feeding on pea plants.
Damage Significant loss of foliage and stunted growth.
Control Install a physical barrier, such as a fence or netting, around the pea plants to prevent rabbits from accessing them.

Commonly, rabbits are known for eating pea plants, causing major damage especially when the plants are budding or just emerging from the soil. They love the succulent stems and will even eat down to the roots, leaving little to none of the plant behind. The chewed off tops of pea plants, primarily at the ground level, are a sign that rabbits are eating them.

Prevention and Control: One effective solution to protect your pea plants from rabbits is installing a chicken-wire fence around the garden. The mesh should be small enough (a 1-inch or less grid) and the fence should be buried at least 6 inches deep to stop rabbits from digging underneath it. Aside from fencing, repellent sprays can also be used whether commercial or homemade such as garlic or vinegar sprays. Just make sure to reapply after rainfall as the scent tends to wash off. Lastly, using live traps baited with apple or carrot slices can also help control the rabbit population. However, it is important to check local regulations on trapping.
