A quick addendum to my last posting. I have just made three wasp traps from soft drink bottles. I’ve cut off their necks and turned them upside down inside the bottle and taped around the top. Using a hole punch I’ve made two holes and threaded garden twine through the bottle to hang. Squeezed the juice from a lemon and lime, added a good scoop of sugar and a little boiling water, stirred until the water is dissolved and then poured into my traps. Fingers crossed several of these hung around the garden will resolve our wasp problem.
