I bought these panels, because I in some small orchids fly
had noticed in the pots and not coinciding with the sizes "bug spray mace"
wanted to advance.
The panels come in a wide, narrow package in itself with again
held a rubber band together and each sheet has two Schutzfoluen (front
and rear) and is pre-cut at the top to attach either a thread
or - as I did - to attach from seed rods.
Those things are extremely sticky and after a short time you see the first insects
plan. I admit there are more appetizing, but think it is better than extensive
Chemical operations.
So summarized: it works (see photo)
