At first I used yellow sticker, but after quickly around 80 Trauermuecken glued to it, I decided to tougher arms to grip.
The product came within 2 days with me.
The guide was briefly and clearly, the application accordingly simple.
Important:
It must not be too hot or too cold at the time of the application (see instructions).
The soil of the plant must for the period of application moist (but not wet) werdem held.
I've taken a water mister currently, the I use daily and will water the earth, rather than pour the pot.
Thanks to Yellow Sticker + nematodes I could see a first effect after about 5 days.
After around 10 days now I see no new final Trauermuecken more.
So if you want fast and reliable remedy is well advised here.
