Use lily varieties that are more resistant to the red lily beetle, such as Asiatic hybrids like Lilium henryi ‘ Madame Butterfly’, Lilium speciosum ‘ Uchida’, and Lilium ‘ Black Beauty’. Entomologists at the University of Rhode Island have identified European parasitic wasps as potential biological control agents against the pest, but these wereps are not yet commercially available.

What gets rid of red lily beetle?

Red lily beetles, also known as Lilioceras lilii, are a beautiful but destructive leaf beetle that can cause significant damage to lily plants. These beetles are 6-8mm long, have a bright red body and wings, and black legs and head.

They lay their eggs on lilies or frittilaries, and are difficult to spot due to their bright orange/red color.

Is there a homemade spray for Japanese beetles?

To control Japanese beetles in your garden, try various methods such as soapy water, soap spray, stomping, companion planting, and milky spore. Soapy water kills beetles by mixing dish soap with water, which can be used in empty beer or soda cans. Spraying the solution on vulnerable plants can also kill beetles, but it may also repel beneficial insects. Stomping is a quick and effective method for removing beetles before they release pheromones. Companion planting, such as garlic, scallions, marigolds, and catnip, can also help keep beetle numbers lower.

Milky spore is the most effective method, as it works on the grub stage of Japanese beetles, which are more active and prevalent late in the season. The ideal soil temperature for effectiveness is 60 to 70 degrees, and it only works on the grub stage. This organic and safe method offers long-term control and only needs to be applied once per season.

However, it is important to note that the first year of treatment may take up to three years to see a significant decline. After a couple of years, the number of beetles may decrease, and even more each year since. Overall, using these methods can help control Japanese beetles in your garden.

Additionally, they offer a comprehensive FAQ section, detailed shipping information, and a hardiness zone map.

How do you use neem oil for beetles?

Neem oil can be used as a spray or soil drench to treat various pests in plants. As a foliar spray, mist the entire plant, covering both the undersides and topsides of leaves and stems. Wear gloves and a mask to protect sensitive skin and lungs. Soil drench involves pouring the diluted solution directly on the soil, treating fungus gnat larvae, nematodes, and other soil-borne pests. The compound azadirachtin, taken up by plants through roots, works as a mild systemic pesticide against certain insects that feed on foliage by sucking plant juices.

Do coffee grounds repel lily beetles?

A reader suggested testing fresh coffee, as the coffee grounds used in the experiment had already been extracted. Caffeine may act as a natural insecticide, making freshly ground coffee a more effective deterrent against incoming beetles.

Seal gaps and cracks in structures where lady beetles may enter, such as siding, doors, windows, chimneys, ridges, soffits, and vents. Pay close attention to areas like pipes, conduit, and utility wires. These proactive measures can help prevent the infestation and protect your home or business from the pests.

Can I spray neem oil on lilies?

Scarlet Lily Leaf Beetle is a destructive pest that can be controlled using natural methods such as hand-picking adult beetles, using soapy water, and scouting plants. Hand-picking is effective for small lily plants, but be vigilant and fast. The beetles are quick and can drop to the soil level, making them difficult to find. To capture and destroy the adults, hold a jar of soapy water under them and nuzzle them off the leaf. Scouting plants several times a week, especially early in the season, is essential.

Safe and organic pesticides like neem oil, a botanical insecticide made from the neem tree, are also effective in controlling the beetle. Neem kills larvae and repels adults, and must be applied every 5 to 7 days. The larvae’s “fecal shield” provides some protection from sprays, so heavy and complete spray coverage is necessary. Late-season larvae may be somewhat resistant to neem.
