I also have vast numbers of pollen beatles and I have companion planted them with my runner beans in an effort to increase pollination of the beans. I am fighting critters all around this year. Slugs as big as mice, rats under next doors shed, lily beatles,mice, black fly on the beans and probably many,as yet unfound. I almost despare. I thought that the harsh winter would have destroyed over-wintering critters.but apparently not. They like my roses and clematis appear to have been invigorated. I wish that I was!
