Lilies, a perennial garden favorite, have been a significant concern for gardeners due to the presence of a small, red beetle called the red lily leaf beetle. This pest, known as Lilioceris lilii, is an important pest from Eurasia that threatens native and cultivated true lilies (Lilium spp.) and fritillaries (Fritillaria spp.). The beetle, which is just under a half-inch long and black underneath, feeds on the leaves, stems, and buds of lilies, including Oriental, Asiatic, and Easter lilies.
The red lily leaf beetle was introduced to North America in the 1940s from Europe and is known to attack all species of lilies, including Oriental, Asiatic, and Easter lilies. Although no known parasitoids exist in North America, seven wasp species and one fly species attack the beetle in Europe. To avoid damage caused by pests and diseases, it is essential to ensure healthy, strong lily plants with the resources available to withstand minor events.
The adult lily leaf beetle is scarlet red on top and black underneath, and is just under a half-inch long. It has an elongated body with a bright red head. As lilies break through the ground, overwintered adult lily leaf beetles will actively feed on the foliage.
While lily beetles do affect Asiatic, Oriental, LA, and Martagon types of lilies, when they overwinter, they can cause leaf drop, weakening the plant. Scarlet beetles, which are 6mm – 8mm long and have black heads, eat the leaves, flowers, and seedpods of lilies and other members of the lily family.

What are the little red bugs crawling around?
Clover mites are small, red insects that crawl around windows and other surfaces in homes. They are not insects but true mites, with an oval-shaped body and eight legs. They feed on clover, grassy lawns, plants, and weeds and appear in large numbers in spring and fall. These insects crawl up the side of a structure from the ground, entering through cracks and openings around windows and doors. Inside, they can be found crawling around window sills, walls, curtains, drapes, furniture, or directly on windows. When smashed, they leave a red stain, which is not blood but the mite’s body pigment.
On the exterior, they can be found on siding, brick walls, under loose bark of trees, foundation walls, and around window frames. They are commonly found on the sunniest side of the house or foundation, often on the south side due to warmth. Clover mites are not dangerous, bite, or cause structural damages like termites. They are simply nuisance pests that can be difficult to eradicate due to their size and ability to invade homes in large numbers. If you have these tiny red bugs invading your windows and home, contact a pest control professional for a free inspection and discuss effective control and preventative measures.
Is neem oil safe for lilies?
Neem oil is a natural pesticide used to control various types of plants, including houseplants, flowering landscape plants, vegetables, and herbs. It is safe for organic gardening and can be used to eliminate garden pests. However, it can have harmful effects if used incorrectly. Different neem oil products are available, and it is essential to understand their differences to choose the best one for your needs. Neem oil, derived from the neem tree, has been used for centuries to control pests and has also been used in medicinal and beauty products.
Some neem oil products work on disease-causing fungi and insect pests, while others only control insects. It is crucial to check the product label to ensure you get an effective neem oil for plants solution for your specific pest problem.
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. However, fresh coffee would be expensive and not suitable for keeping lily beetles out of gardens. Most people drink coffee in winter, but overuse is not good for health due to its hot nature. The reader has been battling beetles using coffee grounds and picking them off, hoping they will move on or die off.
How big are lily beetles?
The red lily beetle, a bright red beetle with a black head and legs, has become a significant threat to lily growers, causing significant damage to popular garden plants like Hemerocallis, lily, rosemary, and berberis. The Royal Horticultural Society (RHS) and the National Biodiversity Network are collaborating to help UK gardeners map non-native pests that cause serious damage to these plants. The RHS science department has submitted 4, 000 entries of location records of four non-native pests, including the Red Lily beetle, Rosemary beetle, Hemerocallis gall midge, and Berberis sawfly, to establish their distribution and spread since their arrival in Britain.
This information will improve advice provided to gardeners and enable an assessment of the threat these non-natives pose to the garden and the wider environment. The input from visitors to the web-based surveys is crucial for understanding the location and spread of these pests.
Are firebugs harmful?
Firebugs, primarily feeding on linden seeds, are not harmful to humans or crops. They are common in Latvia, often found in country parks and plantations with trees, such as linden trees. The second most common species is Graphosoma lineatum, found on wild chervils or other umbellifer plants. LVM Environmental Expert Mārtiņš Kalniņš suggests that removing firebugs is not effective as it would destroy their living environment. Instead, Kalniņš recommends enjoying their natural color and shape.
What is the best bug spray for lilies?
The insecticides carbaryl and malathion have been demonstrated to be effective in controlling adult lily leaf beetles and their larvae. Pyrethroid cyclfluthrin, when used alone or in combination with imidacloprid in the Advanced line, has been shown to be an effective foliar spray.
What are the bright red bugs in the UK?
The red-headed cardinal beetle is a medium-sized beetle found in woodlands, hedgerows, parks, and gardens. Adults are present during the summer, often sunbathing on flowers or tree trunks. They are predators, feeding on other insects flying around the flowers. Their flattened larvae live under loose bark, feeding on other insects’ larvae. The red-headed cardinal beetle is bright red with black legs and long, black, toothed antennae. There are two other cardinal beetle species in the UK: the black-headed cardinal beetle (Pyrochroa coccinea) and the Scarce cardinal beetle (Schizotus pectinicornisis).
Red-headed cardinal beetles are similar to lily beetles in appearance, but the latter has a more rounded body and covered wing cases. The lily beetle was introduced into the UK in the 1900s, arriving on imported flowers.
How can I stop lily beetle?
The Lily beetle, also known as the Red Lily beetle or Lilioceris lilii, is a leaf beetle with around 250 species found in Britain. They feed on plants, including lilies and fritillaries, and are most active from late March-October. The larvae of the beetle and their black excrement-coated grubs consume the foliage of these plants. The adult beetles are rarely found on other plants, but lilies and fritillaries are the only plants where eggs are laid and grubs develop.
Despite leaf damage, plants can produce a good display of flowers, although heavy defoliation in early summer can result in undersized bulbs that may not flower next year. The Lily beetle has become widespread in Britain and Ireland since the early 1990s.
Are scarlet lily beetles poisonous to humans?
Scarlet Lily Beetles are small, half-inch-long beetles that have been consuming plants in the lily family since the last century. They come from Europe and Asia and have been slowly spreading through the US and Canada. They are known to eat true lilies in the Liliaceae family, such as asiatic lilies and fritillaria, but not daylilies. They may also bite out of hollyhocks or hostas but generally leave them alone. These beetles have been observed in the US and Canada, and their presence has led to increased interest in preventing their spread.
Are lily beetles native to the UK?
The red lily beetle, a pest that can devour lily or fritillary plants, has become a significant threat to lily growers. Initially discovered in the late 19th century, the beetle became widespread in Surrey and Berkshire by the late 1950s. By 1990, it was found in Hampshire, Middlesex, Wiltshire, Dorset, Hertfordshire, and Oxfordshire, and by 2005, in almost every English county. The beetle has been reported from Glasgow and Belfast, and it has been consistently one of the top ten pest problems reported to the RHS Members’ Advisory Service. A three-year PhD research degree project was completed in 2008, funded jointly by the RHS and the Horticultural Development Council.
Does neem oil work on red lily beetles?
Hand-picking larvae and adult beetles is an effective method, but time-consuming. Place a light-colored cloth under plants to identify fallen beetles. Neem oil, containing azadirachtin, is effective against adults and small larvae, and should be applied every 5-7 days. 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.
