Insecticide For In-Ground Yellow Jackets

Q: What is the best insecticide to treat an in-ground nest of yellow jackets? 

A: Any insecticide dust would work well. Locate the hole during the day then drop no more than two tablespoons of the dust into the entrance at dusk, when they have all returned to their nest. A dust works well because each insect has to walk over it as they exit the nest. The two tablespoon limit is just a reminder that there’s no need to dump a whole bag into the nest. A little dust around the entrance is all that’s needed.
