You'd probably say that the pests need to be exterminated. But these pests, especially the lily beetle, are quite cunning. They try to nibble on young lily buds when the gardener isn't looking or is busy with other plants.
I usually inspect lily buds during the day and see new ones appearing. If I don't treat them immediately, the beetle will inevitably find them and eat them from the inside. Within a day or two, the buds will turn yellow and fall off. Then, it's possible that several beautiful lilies won't bloom.
This bright red beetle lays pink eggs on lilies, which can deprive the plant of almost all its buds. Its bright color and impressive size (6-8 mm long) make it stand out against the green foliage.
Red beetles on lilies are quite common.
The lily beetle may look beautiful with its scarlet coloring, but it is a very dangerous pest. If this insect is detected, immediate control measures are necessary. It has powerful jaws. Its diet includes not only leaves but also buds, flowers, and even lily stems.
To control lily beetles, I use an organic product: dolomite flour, a natural remedy. Dolomite is a naturally occurring mineral found in nature as a sedimentary rock. Dolomite is composed of oxygen, calcium, and carbon and is found throughout the world. Chemicals can be harmful to bees and other beneficial insects, as well as pets.
All the best!
