water boatmen

6077   Hi, would you be able to identify these bugs and let me know if I should control them.. We started seeing them recently (July 2017) and they are just too many! I live in Edmonton AB. Thank you very much. Ayumi

No need for any control; these are water boatmen (Hemiptera/Heteroptera: Corixidae). These aquatic insects are good fliers and are attracted to lights at night. See https://tinyurl.com/ycngsjtx for more detailed information.  Ed Saugstad, retired entomologist; Sinks Grove, WV.
