Well the trap is installed, along with about a litre of vegetable oil - things could get messy when I next go to see what (if anything) has been caught! I guess if this doesn't work the next step may be to go to IPM and get some nematodes to feed off the pupating larvae! Lets's see how things go over the next couple of weeks!
