How to avoid birds flying into your monitoring trap?

Birds frequently fly into TRAPVIEW housing and feed with caught insects. Some of them can't unstick from sticky panel, some of them leave traces, some of them are more agile and do not, but pests just disappear from sticky panel.

In order to prevent that birds fly into your monitoring trap you can insert the wires on the inlet hole in the housing. The corrugated polypropylene allows that you insert wires in holes and thus reduce the size of the inlet hole as shown on the pictures.
