The lily leaf beetle, also known as the red or scarlet lily beetle, is an invasive insect that poses a threat to ornamental lily plants. Originating from Eurasia, this destructive pest has made its way into gardens around the world. The presence of Lily Leaf Beetles can have devastating effects on your beautiful lily plants.

These DIY organic treatments offer an effective and eco-friendly way to combat the destructive impact of these pesky insects.
Top 10 Homemade Sprays for Lily Beetles
Essential Oil Blend Spray
Essential Oil Blend Spray is a popular homemade solution for getting rid of Lily Leaf Beetles. This spray combines the power of essential oils to repel and deter these pesky insects from feasting on your lilies. To make this organic lily leaf beetle spray, you will need a few drops each of essential oils like peppermint, lavender, and neem oil. These oils not only have strong scents that beetles dislike but also possess natural insecticidal properties.
Mix the oils with water in a bottle and shake well before use. Then, generously spritz the mixture onto your lily plants, focusing on the stems and leaves where beetles tend to congregate. The scent of the essential oil blend will create an unpleasant environment for Lily Leaf Beetles, making them less likely to infest your precious flowers.
Pyrethrin-Based Spray
Pyrethrin-based sprays have gained popularity as an effective and organic treatment for lily leaf beetles. Derived from the flowers of chrysanthemum plants, pyrethrins are natural insecticides known for their quick knockdown effect on pests. When used in this DIY lily beetle treatment, pyrethrins target the nervous system of lily leaf beetles, disrupting their ability to feed and reproduce.
This makes them an excellent choice for controlling these destructive insects without harming beneficial insects or pollinators. To make your homemade lily beetle repellent spray, you can purchase a concentrated pyrethrin extract and mix it with water according to the package instructions. Always follow safety tips when handling any pesticide product, including wearing protective clothing and avoiding contact with skin or eyes.
Rhubarb Leaf Spray
To create this eco-friendly lily beetle solution, gather a handful of rhubarb leaves and chop them into small pieces. Place the chopped leaves in a pot with about two cups of water and bring it to a boil. Let the mixture simmer for about 20 minutes, then strain out the leaves and allow the liquid to cool.
Once your rhubarb leaf spray has cooled down, transfer it to a spray bottle, and you’re ready to start treating your lilies. Be sure to coat both sides of the leaves with the spray, as this will help deter those hungry beetles from munching on your plants. The key ingredient in rhubarb leaves that makes this spray effective is called oxalic acid. This compound naturally repels insects like lily leaf beetles while still being safe for plants.
Tomato Leaf Spray
This homemade spray is not only easy to make but also incredibly powerful in repelling and eliminating these destructive insects. To create lily beetle organic control spray, collect a handful of tomato leaves from your garden or local farmers’ market. Chop them up into small pieces and steep them in hot water for about 24 hours. Strain out the liquid, dilute it with water (typically a ratio of 1 part tomato leaf extract to 4 parts water), and pour it into a spray bottle.
When applied directly onto the foliage of affected plants, the natural compounds present in tomato leaves act as repellents against Lily Leaf Beetles. Therefore, it’s always recommended to test a small area before treating the entire plant.
Mint Tea Spray
To prepare this organic lily beetle prevention DIY, simply steep fresh mint leaves in boiling water for about 10 minutes. Let it cool, and strain the mint tea liquid into a spray bottle. Now, you have your very own mint tea spray ready to combat those unwanted invaders. When you spot any lily leaf beetles on your plants, please give them a generous misting with the mint tea spray. The strong aroma will help deter them from feasting on your precious lilies.
The great thing about using mint as an insect repellent is that it’s completely safe for both humans and pets. Remember to reapply the mint tea spray every few days or after rainfall for maximum effectiveness against these persistent pests. With regular use, you’ll soon notice fewer lily leaf beetles wreaking havoc in your garden.
Onion Spray
The most effective homemade spray for combating lily leaf beetles is onion spray. This natural remedy not only repels these pesky pests but also prevents them from laying eggs on your precious lilies. To make garden beetle control for Lilies, chop up a few onions and steep them in water overnight. The strong odor of the onions acts as a deterrent, keeping the beetles at bay. After straining out the onion pieces, transfer the liquid into a bottle and apply it to your plants.
The sulfur compounds present in onions are what make this spray so effective against lily leaf beetles. Remember to reapply the onion spray every week or after rain showers to ensure continuous protection for your lilies.
Epsom Salt Spray
This natural treatment not only helps get rid of these pesky pests but also nourishes your plants at the same time. To make this natural lily beetle remedy, dissolve Epsom salt in water. Mix well until the salt has dissolved. Then, transfer the solution to a bottle and apply it directly to your lily plants.

When sprayed on the leaves, it creates an environment that repels them from feeding and laying eggs on your precious lilies. Furthermore, Epsom salt is known to improve plant health by promoting better nutrients and enhancing overall growth.
Cedar Oil Spray
The strong scent of cedar oil acts as a deterrent for these pesky insects, keeping them away from your precious lilies. To make the cedar oil spray, mix about 10 drops of pure cedar essential oil with a quart of water in a spray bottle. Shake well to ensure thorough mixing. Then, spray the solution onto the plant leaves and stems.

To make this spray, you will need a few simple ingredients: citrus peels (like oranges, lemons, or grapefruits), water, and a spray bottle.
