A garden would be so beautiful if there were not always insects to feast on. Clematis is high on the menu of the black weevil.Weevils are particularly active at night
What is a weevil?
This is a roughly one centimeter tall, black beetle that is particularly active at night. If you discover feeding spots at your Clematis, you should arm yourself with a flashlight at dusk and go in search of this plague. If you discover the beetle, you can carefully collect it. It is important that you do not touch the leaves beforehand, because it is very frightful and easy to fall. Incidentally, he cannot fly away.
The larvae of the black weevil
The larvae of the black weevil are particularly harmful. This annoying vermin lays the eggs on the bottom of the plant. The larvae then live in the soil and feed on the roots. And that damages the clematis even more. The older larvae can even work their way down to the main root and damage it.
Nematodes help against both the beetle and the larvae. These are roundworms that you can use for plant protection. These worms are just 0.1 millimeters in size and can therefore get into the vermin through the body openings and the skin. There they deposit a type of bacteria that is dangerous for weevils, which then kills them.
