Wary of Wasp Nests

Can you identify which wasp nest is the biggest worry? Wasps don’t attack unless threatened, but what constitutes a threat to a wasp? Sometimes it is our unintentional actions such as stepping on a hidden wasp nest. That is why the yellowjacket wasp nest in photo C is the most worrisome. Not only are yellowjacket wasps aggressive by nature, they often build nests in old rodent burrows. Read more about yellowjacket wasps and control HERE.
