Damage caused by black vine weevil and its larvae

The black vine weevil is one of the most important pests in gardens and roof gardens. Its larvae feed especially on the roots of plants, which can cause wilting and eventual death. The adult beetles feed primarily on the leaf edges of the affected plants, resulting in the typical and unsightly "bay feeding".

Sehr gute Wirkung, leider auch gegen Kellerasseln

Wir haben uns 2 Fallen in den Garten gelegt, weil wir große Schäden an unseren Rhododendren hatten. Nach ein paar Tagen haben wir viele tote Käfer unter den Fallen gefunden, aber auch einige Kellerasseln, die uns eigentlich nicht stören. Trotzdem immernoch deutlich besser als Gift zu versprühen!

Application of nematop® weevil-stop

Simply place the trap near the infested plants. Make sure that the grooves point downwards. The nocturnal beetles hide during the day and crawl under the trap. There they come into contact with the nematode gel. The nematodes now penetrate into the beetles and fight them.
