Against the Wolläuse on my orchids I first tried the product of Neudorff. On the bottle is already that it leaves stains in the area, if you are not covering everything ... ended with me in Balkonschrubben. The spray is something charming and overall it's not as productive as a similar product of Compo, I've tried the same in the connection - because in my many orchids, the bottle was empty after only one and a half applications and the lice still there. They have moreover been unimpressed that has the other product definitely better hingekriegt.
