what to do about cicada killers on front lawn
This is the second year they have appeared. They are in our lawn. Last year we let them be, because I read that they are beneficial. But they are where we need to walk and mow frequently, and we don't want to get stung by one who is defending itself. I really don't feel comfortable with them in our yard. How can we safely get rid of them? Thanks!
Cicada killer wasps are considered beneficial as they keep the cicada population down and should be tolerated if possible. They usually do not bother people even when provoked. There are no easy control solutions. Modify the habitat and make the area unattractive to burrowing.
In lawns thicken your stand of turf by overseeding in the fall. Reduce exposed soil in ornamental beds by planting groundcovers and applying mulch. In new beds pin down landscape fabric with landscape pins and cover with mulch.
