10 Ways to Control Lily Leaf Beetles and Protect Your Garden Plants

Lily Leaf Beetle and Its Impact

Have you ever noticed a small, red beetle on your lilies or hostas, munching away at the leaves? Chances are, it was a Lily Leaf Beetle.

These colorful insects may look harmless, but they pose a significant threat to your garden. In this article, we will explore the Lily Leaf Beetle’s life cycle and where they lay their eggs.

Lily Leaf Beetle is a notorious pest that infests lilies, hostas, Solomons Seal, hollyhocks, daylilies, canna lilies, and calla lilies. This insect is a significant problem in the northeastern United States and Canada, where it has been present since the early 1990s.

They also pose a threat to newly planted gardens, as they lay their eggs in the soil. The larvae of Lily Leaf Beetles are responsible for the damage caused to plants.

These larvae are black, with orange stripes and spines. They feed on the leaves and can strip a plant entirely in a few days.

Once the larvae have finished feeding, they drop to the soil and pupate. After pupating, the adult Lily Leaf Beetle emerges from the soil and begins to feed on the leaves, starting the cycle again.

It is essential to remove the larvae as they can cause the most harm.

Where Lily Leaf Beetles Lay Eggs

Lily Leaf Beetles prefer to lay their eggs on the underside of lily leaves, hostas, and Solomons Seal plants. They may also lay their eggs on the underside of hollyhock leaves, daylilies, canna lilies, and calla lilies.

The eggs are small, oval-shaped, and colored bright red or yellow-orange. They cling to the underside of the leaves, where they are well-hidden from predators.

The Identification of Lily Leaf Beetle Eggs

If you suspect that your garden has been infested by Lily Leaf Beetles, your first step is to identify the eggs. To do this, you need to know what the eggs look like.

Lily Leaf Beetles lay their eggs in clusters, and they are easy to spot on the underside of leaves. They are approximately 1mm in size, and depending on their stage, they can be red or yellow-orange in color.

While Lily Leaf Beetles are known to prefer lilies and hostas, it is important to note that they can infest other plants, too. It is crucial to regularly inspect your garden for signs of infestation, including eggs, larvae, and adult beetles.

Early detection of infestation can prevent severe damage to your plants.


Overall, the Lily Leaf Beetle is a notorious pest that poses a threat to lilies, hostas, Solomons Seal, hollyhocks, daylilies, canna lilies, and calla lilies. It is essential to know where Lily Leaf Beetles lay their eggs and how to identify them to prevent infestation in your garden.

By regularly inspecting your plants and quickly removing any signs of infestation, you can protect your garden and ensure its health for years to come.

Getting Rid of Leaf Beetle Larvae and

Repelling Adult Leaf Beetles

Lily Leaf Beetles can be incredibly damaging to your garden plants. They pose a threat to lilies, hostas, Solomons Seal, hollyhocks, daylilies, canna lilies, and calla lilies.

These pests are mainly known for their destruction and can damage your plants to the point of death. In this article, we will look at several ways to get rid of Leaf Beetles’ larvae and repel adult Leaf Beetles from your garden.

Hand Removal of Eggs and Larvae

One of the simplest and most effective methods to remove Lily Leaf Beetles’ eggs and larvae is by hand. If you inspect your plants regularly, you can remove and destroy any visible larvae and eggs that you find.

A quick way to get rid of larvae you spot is to mix water and dish soap or insecticidal soap in a spray bottle and apply directly to the pest.

Spraying Larvae off with a Hose

Another method to get rid of Leaf Beetle Larvae is spraying them off with a hose. Set your hose to the jet setting and spray the plant’s affected areas.

The water pressure will force the larvae off the plant. This is a good way of getting rid of the larvae without using any chemicals or pesticides.

Use of Ladybugs as Natural Predators

Ladybugs are a natural predator to Lily Leaf Beetles. Having ladybugs in your garden will help regulate and control Leaf Beetle populations.

Ladybugs and their larvae feed on Leaf Beetles eggs, larvae, and adult beetles. You can also introduce naturally-occurring parasitic European wasps that eliminate Leaf Beetles.

Inviting predators like ladybugs and wasps to your garden is a safe and natural way to control Leaf Beetle populations.

Application of Castile Soap and Dish Soap

Another non-invasive way of controlling and preventing Leaf Beetles is using Castile soap mixed with water and spraying it on the affected areas of the plant. Dish soap sprayed directly on the leaves will also eradicate Leaf Beetles.

These soaps kill the pest’s nervous system, rendering them lifeless and predictable in a matter of minutes.

Use of Neem Oil

Neem oil is a potent natural fungicide and pesticide. It also repels and eliminates Lily Leaf Beetles.

Applying Neem oil to your garden will repel Leaf Beetles. You can mix a few tablespoons of this oil in water along with dish soap and spray your plants regularly.

The Neem oil’s taste and smell make it difficult for the Leaf Beetles to survive.

Diversifying Plant Species

Plant diversity is a crucial way of helping your garden plants to thrive. Diversifying plant species can also keep Lily Leaf Beetles at bay, as they may prefer lilies or hostas over other plant species.

Including ground cover and companion planting in your garden design plans can significantly reduce Leaf Beetle populations by making it harder for them to find their ideal host plants.

Prevention of Pupating in the Soil

Removing the possibility of pupation is another effective way to control Lily Leaf Beetle’s populations. Trap and prevent pupation by applying Tanglefoot Pest Barrier.

You can also lay cardboard or newspaper on the soil to prevent adult beetles from laying their eggs on the ground.

Repelling Adult Leaf Beetles

Adult Leaf Beetles are challenging to eliminate, but you can take several preemptive measures to keep them at bay.

Use of Castile Soap and Neem Oil

The combination of Castile soap and Neem oil is an effective natural repellent to adult Leaf Beetles. Create a solution with equal parts Castile soap and Neem oil with water and spray your plants regularly.

This will repel Leaf Beetles and prevent damages.

Use Strong Herbs such as Garlic and Onions

Strong-smelling herbs such as garlic and onions are natural repellents to Leaf Beetles. Companion planting with plants from this family can significantly help reduce Leaf Beetle populations.

Use of Coffee Grounds

Coffee grounds contain acidic compounds that repel Leaf Beetles. Sprinkle coffee grounds around the base of your plants or apply a diluted coffee solution to repel Leaf Beetles.

Encouraging Predator Insects and Birds

Birds such as bluebirds and wrens, feed on adult Leaf Beetles. Installing bird feeders or planting bird-friendly plant species such as sunflowers may attract birds naturally.

The introduction of ladybugs to your garden will also help keep these pests in check.


Getting rid of Lily Leaf Beetle larvae and repelling adult Leaf Beetles can be challenging. Using natural methods such as Castile soap, Neem oil, diversifying plant species, and predator insects can be useful at keeping these pests in check.

By incorporating preventative measures, regular plant inspection, and control tactics will help keep your plants safe and allow them to thrive.
