My family and myself noticed these insects this summer flying around and crawling between the interlocking stone and the pool this summer. They keep flying around us whenever we swim and I’m worried somebody is going to get stung. I’ve also noticed them carrying locust into their nest which I figure is in our pool area. Is there any way I can remove these from this area?
This is a Great Black Wasp, Sphex pensylvanicus, and it is not an aggressive species. You mentioned seeing the female with a locust. BugGuide notes that they prey upon Katydids which earns the species an additional common name Katydid Hunter. Since they are not aggressive, we would urge you to just let them cohabitate with you in your yard and to refrain from killing any more individuals of this magnificent wasp.
