It is autumn in New England and holly bushes are being swarmed by wasps, bees and other insects. I believe this is caused by aphid secretions and the holly flowers that bloom at this time. Are there any treatments that will help deter this from happening?
Yes, the sugary "honeydew" produced in potentially copious quantities by aphids is a major attraction to sweet-feeding insects, and as the weather dries and cools in the fall there may be fewer other options available, making the honeydew that much more attractive. Insects like honeybees, in particular, are trying to increase their stores of honey so they can survive the winter, while wasps and other bees may just be there to live as long as possible. Who knows but other insects may be predators that feed on the aphids or even on the bees and wasps that frequent these plants.
