This morning I received an email from Norm
Subject: cocoon removal
“ I have the cardboard tubes with liners.
Is it possible to remove the cocoons from this type nest?”
Yes it is possible. First try pulling out the liners. If the liner is dry, you can remove the liner and replace the tube with a clean liner. Unfortunately if there is any moisture, the liner absorbs moisture and breaks when you try and remove the liner. If this happens, the cardboard tube has to be unraveled to get the cocoons out.
