Hervorragende Wirkung

Wir hatten letztes Jahr enorme Probleme mit Dickmaulrüsslern im Garten und haben letzten Herbst und dieses Jahr im Mai Nematoden eingesetzt und sind bislang absolut begeistern. Die Anwendung war sehr einfach und man muss sich keine Gedanken machen den Hund danach in den Garten zu lassen.

Gute Wirkung

Ich fand die Anleitung etwas kompliziert bzgl. mischen und verdünnen, aber habe dann eine nette telefonische Hilfe bekommen. Die Nematoden haben dann super gewirkt.
