Two days ago I stumbled upon a underground nest out back in an area that is natural vegetation .. yet a place that gets mowed a few times each summer. From a quick google search on how to eradicate the pests, most advised to leave late summer nests alone to let the first good frost kill the nest .. at which time closing it off. This nest has an entrance hole 3 inches wide. Hubby got stung while watering in the general area .. after I warned him about the bees. (Knowing him, he probably let the hose spray water over the nest ... he's a guy .. just saying).
I've seen these little buggers completely devour dead birds and insects .. bones and all in the course of a day. Not one to wish away time .. the first good frost is mighty appealing right about now.
