will hornets return to a nest year after year? What's a good way to get rid of a large hornets nest? Professional help?
Denver County Colorado
A colony of hornets builds a new nest every year from scratch. Since it is so late in the season, unless the nest is in a high traffic area, you could just ignore it.
If you prefer to get rid of it, you either could hire an exterminator or use one of the aerosol products available at hardware and big box stores that are labeled for hornet and wasp removal. If you remove it yourself, follow the label instructions.
