I bought this fly trap the other week from our hardware store and while it doesn’t have poison in it, the contents are surely popular with the flies. In fact so much so I ultimately threw it out as it was far too effective, and consequently rather gross.
Meanwhile the wavy paw lizard was only too happy. He worked out that the flies were there and stationed himself above the lid feasting on a fly smorgasbord. I guess I’ve made it harder work for him now it’s gone.
