Best Insecticide For Lily Beetles

Introduction

If you’ve never had lily beetles, consider yourself lucky. They’re the most destructive insect pests of true lilies and fritillaries and are rapidly spreading throughout North America, where they were only introduced in the 1940s. These inch-long beetles have voracious appetites; a single adult can eat an entire leaf in 24 hours, leaving behind nothing but the veins. The larvae do even more damage, as they tend to eat their way through the buds before moving on to leaves and stems. If you find these pests, it’s important to get rid of them quickly with one of our recommended insecticides below so they don’t take over your garden completely.

Organic Insecticides

Organic insecticides are made from naturally occurring ingredients, including plant-based oils, minerals and mineral salts. Organic insecticides contain the same active ingredient as synthetic insecticides but without chemical additives that can cause harm to humans or the environment. Organic pesticides have been used for centuries by farmers to protect crops from insects. These products are considered safer than synthetic pesticides because they do not persist in soil like many chemicals do; therefore, there is a lower risk of harmful effects on wildlife when used properly.

However, organic pesticides are more expensive than synthetic ones and may be less effective against pests such as lily beetle larvae. In addition, it is difficult for homeowners to apply these products effectively because there are fewer options available at local garden centers; therefore homeowners must be willing to spend extra time researching how best to use them so they will work properly on their plants

Neem oil

Neem oil is a natural insecticide, made from the seed of neem trees. It is non-toxic to humans and does not harm honey bees or other beneficial insects. Neem oil is effective against lily beetles and whiteflies, but it also works well against other pests such as aphids and mealybugs.

Neem oil prevents larvae from maturing into adults by disrupting their life cycle in the egg stage; adult beetles are killed when they ingest this substance during feeding on plant leaves.

Pyrethrin

Pyrethrins are the most common ingredient in insecticides and are made from the Chrysanthemum flower. Pyrethrins are not toxic to humans or animals. They work as contact pesticides by attacking nerve cells and making insects unable to function normally.

While they are considered safe for use in organic gardening, they may be harmful if inhaled or ingested in large amounts.

Diatomaceous earth

Diatomaceous earth is a natural powdery substance that’s made from the shells of diatoms—a type of algae. It’s non-toxic, but works by absorbing moisture from insects’ bodies and dehydrating them to death.

Because it’s so light and easy to handle, DE is sometimes used as an insecticide rather than a pesticide (which includes chemicals). The powder can be applied directly onto plants or soil for effective control of many pests. You’ll find diatomaceous earth in most garden centers, hardware stores and online retailers like Amazon.

Pest Oil

The best thing about Pest Oil is that it’s a natural product made from the neem tree. It’s safe for humans, pets and birds. It’s also an organic insecticide that can be used around food crops and ornamental plants.

Pest oil works by smothering the lily beetle, which makes it a contact pesticide. This means you are applying pest oil directly on top of where the adults lay eggs and hatch larvae in order to kill them before they grow up into adults themselves—so it’s important to apply pest oil at the beginning stages of their life cycle!

Bt (Bacillus thuringiensis)

Bacillus thuringiensis (Bt) is a naturally occurring bacterium that produces toxins harmful to insects. Bt has been used as an insecticide for decades, and was first registered by the EPA in 1976. While this insecticide is often considered organic, it’s also registered with the EPA as an insecticide.

Bt products are formulated with specific strains of Bt based on the type of pest they’re targeting. For example, there are different strains of Bt that target mosquitoes or fleas than there are strains that target caterpillars or other insects. The EPA regulates what type of product should be used against each species because some insects may be more susceptible than others. According to the Center for Disease Control (CDC), “The risk of developing illness from these products is extremely low.”

Horticultural vinegar

Horticultural vinegar is a safe and effective option for organic gardens. It’s also one of the least expensive insecticides, so it’s more cost-effective than many chemical options.

While horticultural vinegar can be used to kill lily beetles, the best time to apply it is when they are adults. Horticultural vinegar isn’t as effective at killing larvae or eggs, which means you should plan on treating your garden with horticultural vinegar every year until it becomes infested with lily beetles again.

Synthetic pesticides

While synthetic pesticides are the most effective and widely used insecticides, they have their drawbacks. They kill all insects they come into contact with, including beneficial ones like bees and birds. They can also cause health issues in humans and animals if ingested or inhaled in high enough quantities.

The best way to use a synthetic pesticide is in combination with another method, such as an organic spray or a barrier around your plants that will keep the lily beetles out completely.

Use insecticides from the list to get rid of lily beetles

The insecticides on the list are a good starting point for your treatment, but you may need to use a combination of them. To be effective, you’ll also want to reapply the insecticides if they don’t work—and make sure you don’t spray too much of any one product.

Conclusion

In this article, we have covered the 8 best insecticides that you can use to get rid of lily beetles. The best way to prevent lilies from being infested with these pests is to plant them in an area that receives full sunlight. The plants will be less likely to attract both adult and larvae beetles when they are grown in direct sunlight. We recommend baits because they provide a simple method for killing the adult beetles, which can then be picked up by hand or vacuumed up before they lay their eggs again next springtime. Additionally, it’s important not to use any kind of herbicide on your garden as these chemicals could harm beneficial insects like ladybugs or praying mantises which help keep other destructive pest populations down too!
