Hey there, I have also been involved in work with OPM the last couple of years, primarily surveying for them in various places. I've just finished many weeks of pheromone trapping for the OPM around London. Where have you been trapping in the past? From the information I've collected on the spread of the OPM it looks like eradication is out the window, its largely spread West and South of London now and I do believe it be near out of hand. Ive also found the moths in far north london aswell just in smaller numbers as elsewhere.
