How To Control Lily Beetle



How to control lily beetle? The lily beetle (Lilioceris lilii) is a notorious pest that can wreak havoc on lilies and other members of the Liliaceae family. These bright red beetles, along with their larvae, feed on the leaves, stems, and flowers of lilies, causing significant damage and potentially killing the plants if left unchecked. Controlling lily beetles is essential to protect the beauty and health of your lilies. In this article, we will explore various methods and strategies to effectively control lily beetles and minimize their impact on your garden.

1. Manual Removal

One of the simplest and most effective ways to control lily beetles is through manual removal. Regularly inspect your lilies for the presence of adult beetles, which are easily identifiable by their bright red color and black head. Wear gloves and pick off the beetles by hand, dropping them into a bucket of soapy water to kill them. Be sure to check both sides of the leaves and stems, as the beetles have a tendency to hide. This method is particularly useful in the early stages of an infestation or for smaller gardens.


2. Neem Oil

Neem oil, derived from the neem tree, is a natural insecticide that can be used to control lily beetles. Dilute neem oil according to the manufacturer’s instructions and spray it onto the leaves, stems, and flowers of your lilies. The oil disrupts the life cycle of the beetles, inhibiting their feeding and reproductive abilities. Neem oil is safe for beneficial insects and does not harm the environment when used correctly. Repeat the application every 7-10 days or as needed, especially during the peak beetle activity period.


3. Biological Control

Introducing natural predators of lily beetles can be an effective long-term strategy for controlling their population. Ladybugs and their larvae, as well as lacewings, are known to feed on lily beetle eggs, larvae, and adults. Encourage these beneficial insects to your garden by planting nectar-rich flowers, such as daisies and marigolds, which attract and provide sustenance for them. Additionally, you can purchase ladybugs or lacewings from garden centers and release them near your lilies.


4. Chemical Control

If the infestation is severe or other methods have proven ineffective, chemical control may be necessary. There are several insecticides available specifically formulated for lily beetles. Look for products containing active ingredients such as pyrethroids or imidacloprid. Always read and follow the instructions on the label carefully to ensure safe and effective use. It is important to note that chemical control should be used as a last resort and with caution, as it may harm beneficial insects and other non-target organisms.


5. Cultural Practices

Implementing certain cultural practices can help prevent and reduce lily beetle infestations. Start by maintaining good garden hygiene, removing fallen leaves and debris where the beetles may overwinter. Consider planting lilies in containers or raised beds, as this can make it more difficult for the beetles to reach the plants. Applying a layer of organic mulch around the base of the lilies can also act as a deterrent. Additionally, regular fertilization and proper watering can promote healthy plant growth, making them less susceptible to beetle damage.



Controlling lily beetles requires a combination of proactive measures, including manual removal, neem oil application, biological control, and cultural practices. By implementing these strategies, you can effectively manage lily beetle populations and protect your lilies from their destructive feeding habits. Remember to regularly monitor your plants for signs of infestation and take prompt action to prevent further damage. With patience and diligence, you can enjoy beautiful, lily beetle-free gardens.

We thought we had bedbugs but could find no evidence apart from what we thought were bites. I called Bon Accord and Gabriel was there within a couple of hours. He told us we had carpet beetle. Finding the evidence and showing us photos of the skin reaction which was exactly what we had. He advised and returned at a time to suit us to spray which was done thoroughly and efficiently. No sign of the little critters returning. Thank you Gabriel.

Gabriel was absolutely wonderful, a real life saver when I found a mouse by my bed at 10pm. He came in less than an hour and was able to catch the mouse and put my mind at rest so I could go to sleep! Highly recommend, fab service and lovely people.

Gabriel turned up with an hours notice one evening and immediately identified the issued. He works efficiently and professionally throughout with timely follow-ups to ensure the problem was resolved. Once completed he was kind enough to continue to check in to see that the issue had gone. Having had Rentokil previously that spent two years doing very little this was a complete breathe of fresh air and solved the problem in less than two weeks. We are grateful and would highly recommend his services.

We were lucky to have found Bon Accord, they responded very fast to our request and Gabriel was very helpful and informative. He made several visits and did his absolute best until the mice problem we had was gone. Highly recommended.
